Psoriasis

What they are: Facial moisturizers are designed specifically for use on delicate facial skin. Some may be designed for specific areas of the face, such as around the eyes or mouth.

Why to buy: Facial moisturizers are the right option to properly hydrate facial skin and keep it supple. Hand creams and other body moisturizing products tend to be too heavy; resist the temptation to use these instead of face-specific products.

Things to consider: Pay attention to labels and use only as directed. For example, many products are not designed for use on eyelids or close to the eyes, and will sting if applied to these areas. Pick products to meet your needs. Facial moisturizers range from items to treat very dry faces to light moisturizers for acne-prone skin. Expensive may not be better. Ask your doctor or friends and family members for suggestions.

What they are: Body moisturizers come in lotions and thick creams and tend to be heavier than facial products and lighter than hand and foot moisturizers. They often contain humectants—substances to seal moisture into skin, and come with or without fragrance.

Why to buy: Body moisturizers provide the right weight to keep you feeling soft and velvety all over. Many like to keep a good body moisturizer around so it’s always there to use when needed. Some people use them year round, while others only need them during specific dry seasons.

Things to consider: Fragrances in lotions and creams are the most common culprit for allergic reactions. If you’ve had problems with moisturizers in the past, try a product formulated for sensitive skin or that is fragrance-free.

What they are: Moisturizers for hands and feet tend to be the heaviest, most moisturizing products available. Skin on hands and feet is thicker, tougher, and may be more exposed than other areas; these body parts may need a heartier product.

Why to buy: These products are reasonably priced and can address serious dryness, such as cracked heels and chapped, irritated hands. They provide the deepest moisturizing for the areas that need it.

Things to consider: These products are best for thicker, tougher skin, so avoid using on the face or other sensitive body areas where they may clog pores.

What they are: Specialty moisturizers for dry patches are formulated to address a specific concern, such as dry elbows or knees. These products may contain substances that speed up cell turnover in the skin, so the outer layers of dead skin are shed more quickly. This allows the moisturizer to penetrate to where it is most needed.

Why to buy: If you have a very dry body area, especially elbows, knees, heels, or hands, a specialty product can help get the problem under control.

Things to consider: As with hand and feet moisturizers, these products are formulated for very tough, dry skin. They often do not work well on delicate facial skin.

What they are: Chemical sunscreens contain ingredients that react with the sun’s radiation as it hits your skin, preventing the rays from harming skin.

Why to buy: Chemical sunscreens are found in many water-resistant products because they tend to have more “staying power” than other sunscreens. Chemical sunscreens tend to be less expensive and come in easy-to-apply options, such as lotions, gels, sprays, wipes, and sticks.

Things to consider: Some people have allergic reactions to certain chemical sunscreen ingredients. Common offenders include PABA, cinnamates, oxybenzone, and salicylates. If you’ve had skin reactions to chemical sunscreens, try a brand that is free of the chemicals to which you've reacted (if known). Also, try fragrance- and oil-free products to minimize skin reactions.

When sunscreens wash off the skin, they enter the environment. Some chemicals used in sunscreens have been shown to damage coral, and to accumulate in fish and other marine life, where they act as hormone disrupters.

In 2011, the FDA expressed concerns about spray-on sunscreens, especially for children, since it is unclear whether this method of application leads to inhalation of unsafe chemicals, or adequately protects against sun damage.

What they are: Physical sunscreens contain finely ground mineral particles, such as zinc and titanium salts, that form a physical “shield” against the sun’s radiation. The two most common physical sunscreen ingredients are zinc oxide and titanium dioxide.

Why to buy: Physical sunscreens are less likely to cause skin irritation and rashes than chemical sunscreens, making them an attractive option for young kids and adults with sensitive skin. For consumers who prefer to reduce chemical exposure, many health experts advise using physical sunscreens and many pediatricians recommend them for children under two years.

Things to consider: Physical sunscreens, when properly applied, usually give a white appearance to the skin. To reduce this effect, some manufacturers have developed more transparent zinc oxide and titanium dioxide sunscreens using so-called nanoparticles. Although concerns have arisen regarding the potential harms of nanoparticles of zinc and titanium salts, the research so far indicates that they do not pose health dangers.

Physical sunscreens are likely to cost more by volume than chemical sunscreens. In addition, some people find that physical sunscreens “sweat off” more easily, which means they have to be reapplied more frequently to ensure protection.

Keep in mind that even physical sunscreens can contain fragrances or oils, both of which may irritate skin.

What they are: All-natural sunscreens contain only physical sun-blocking ingredients, and may contain herbs and other plant extracts to soothe the skin as well. They do not contain synthetic chemicals, fragrances, or oils.

Why to buy: For those who have children with extremely sensitive skin or very young children, all-natural sunscreens can be a good option.

Things to consider: Because these sunscreens contain physical sun-blocking agents, all of the concerns associated with physical sunscreens apply to all-natural sunscreens. All-natural sunscreens are not as resistant to water and sweat, so a single application may not provide enough protection for a long day at the beach or pool. Be sure to reapply them often to maximize the benefits.

What they are: Long-wear and water-resistant sunscreens are designed to offer the best protection in active situations, such as during exercise or when swimming. Product labels will tell you whether they have been rated for 40 or 80 minutes of protection. After that time they must be reapplied for full sun protection.

Why to buy: For active people, long-wear and water-resistant products may be the only type of sunscreen that truly protects against sun damage. If you tend to sweat a lot or like to swim, these products can be a good option.

Things to consider: Many people find long-wear sunscreens feel “sticky” or “greasy” on the skin. While this may be annoying, this is the reason these products can stand up to sweat and water while still offering sun protection. Labeling requirements allow a product to be called water “resistant,” but not “water-proof” or “sweat-proof.”

What they are: Sunscreens marketed for kids can contain chemical or physical sun-blocking ingredients, or sometimes a combination of the two. These products are usually designed to be safer and gentler on the skin, and often do not contain the chemical ingredients most likely to cause irritation or allergic reactions or pose health harms (PABA, cinnamates, oxybenzone, and salicylates).

Why to buy: Try a kid-friendly sunscreen for your family, especially for children younger than 12 years. The most kid-friendly products contain only physical sun-blocking ingredients.

Things to consider: There are no regulations guiding the use of the words “children,” “kids,” and “family” in product names or marketing—in some cases, these products are no different than those marketed for general use. Sunscreens marketed as kid-friendly tend to cost more, so be sure the formula is truly gentle and safe.

Sunscreens are not recommended for babies under six months old. Babies should be protected from the sun by keeping them in the shade or covered up if they have to be in the sun.

What they are: Face self-tanners come as gels, lotions, creams, and towelettes. They deposit DHA, the key “tanning ingredient,” onto the skin. Products for the face often give a more subtle color than those designed for the body. Face self-tanners tend to be of thinner consistency and come in oil-free and non-comedogenic (non-acne-causing) varieties, to minimize the risk of skin breakouts.

Why to buy: Any tan that you achieve naturally, with sun exposure, causes skin damage; a self-tanner is the only “safe tan.” Products are available that develop into a variety of colors, from light to dark tan, so you can customize the color. Many products can be applied for several days in a row, so the color deepens slowly over time, allowing you to control the end result.

Things to consider: Fragrance is one of the most common culprits in causing negative skin reactions to new products. If you have sensitive skin, opt for an unscented product with the fewest ingredients. If you get no sun, you may want to consider taking a vitamin D supplement to avoid deficiency.

What they are: Body self-tanners come as oils, gels, lotions, creams, and towelettes. They are used to deposit DHA, the key “tanning” ingredient, onto the skin. Products for the body often give more color than those that are designed for the face. Body self-tanner lotions and creams often have a thicker consistency, since body skin tends to be dryer than face skin.

Why to buy: As with the face, the only safe tan on the body is one that comes from a self-tanner. Sun exposure to achieve a tan can increase the risk of premature skin aging and skin cancer. Products come in such a wide variety of forms so that nearly everyone can find a product that works well and gives the desired color result.

Things to consider: Exfoliating and shaving, both of which may remove the outermost layer of skin cells, will speed up how quickly your tan fades. Try exfoliating and shaving your legs before applying self-tanning products to get the longest-lasting result. Moisturizing frequently will prolong the length of your self-applied tan as well.

What they are: Antibiotic and pain-relieving ointments and creams are a combination of antibiotics and analgesics, or pain-relieving ingredients, easily applied to the skin.

Why to buy: To prevent infection and provide immediate topical pain relief for minor cuts, scrapes, and abrasions, antibiotic and pain-relieving ointments and creams are a good choice.

Things to consider: Use caution when applying ointments to skin that is close to clothing as they may stain, or find formulas that claim to be greaseless and non-staining. If over-the-counter aids don’t help and you suspect an infection, talk with your doctor. Many cuts, scrapes, mild sprains, and strains can be treated at home, but puncture wounds are a different story. These injuries introduce bacteria deep into body tissues and require professional medical care to avoid serious complications. Treat animal bites first at home, but follow up with your doctor, even if the bite seems minor. Animals in general, and cats in particular, may have dangerous bacteria and viruses in their mouths, which can lead to serious, and even life-threatening infections.

What they are: Anti-inflammatory ointments and creams are low doses of anti-inflammatory medications, such as aspirin, trolamine salicylate, and menthol, which can be easily applied to the skin. Some also contain Aloe vera for added soothing.

Why to buy: Anti-inflammatory ointments and creams may reduce swelling and inflammation, offering relief from arthritis pain and minor muscle aches.

Things to consider: If you’re sensitive to smells, choose unscented ointments and creams. Do not use aspirin-containing ointments on children or teens with a fever, due to risk of Reye’s syndrome. Any injury that results in major swelling, misshapen joints or bones, or severe bruising requires medical attention.

What they are: Ointments for dry, cracked or irritated skin contain petrolatum and other soothing ingredients to help restore smooth, healthy skin and temporarily protect minor cuts, scrapes, and burns.

Why to buy: These ointments offer effective healing, soothing, and moisturizing for eczema, chapped lips, and severely dry, cracked skin. They can also protect skin from the harsh, drying effects of wind and cold weather.

Things to consider: Talk with your doctor if conditions worsen or symptoms last more than a week, or clear up and occur again within a few days. Do not use on deep or puncture wounds, animal bites, or serious burns. For sensitive skin, look for fragrance-free options.

What they are: Eye ointments are sterile lubricating ointments that soothe and moisturize dry, irritated eyes, and relieve the burning, itching, and discomfort associated with a sty. For optimal results, most ointments are applied to the inside of the lower eyelid before bedtime and contain mineral oil and white petrolatum as active ingredients.

Why to buy: If you suffer from severe dry eyes, applying lubricating ointments at bedtime may soothe and moisturize. For relief from corneal edema—inflammation of the cornea due to infection, ocular diseases, surgery, or prolonged use of contact lenses—try sodium chloride hypertonicity ophthalmic ointments, available in various strengths.

Things to consider: Over-the-counter eye ointments are designed to treat symptoms and are not a cure for infection. If you think you have an eye infection, see your doctor.

What they are: Diaper creams and ointments offer gentle, easy-to apply treatments for painful diaper rash and other minor skin irritations. Most contain zinc oxide and dimethicone, proven skin protectants. Some also contain petrolatum, lanolin, plus soothing ingredients like Aloe vera, lavender, and chamomile.

Why to buy: Diaper ointments and creams soothe and heal your baby’s delicate skin. Diaper rash ointments protect the skin from chafing and minor irritations, plus they seal out wetness to help prevent diaper rash.

Things to consider: If your baby has sensitive skin, look for fragrance-free creams. Many diaper rash ointments may also be used on other parts of the body, including chafed, chapped, or cracked skin and lips.

What they are: Antifungal ointments and creams contain a variety of medicated treatments for athlete’s foot and other fungal infections of the skin. Active ingredients include tolnaftate, undecylenic acid, and zinc undecylenate.

Why to buy: Antifungals can fight the fungus that causes athlete’s foot, ring worm, and jock itch and provide immediate relief for itchy, scaly skin. Daily use of the appropriate ointment or cream may also prevent recurrence of athlete's foot.

Things to consider: If you don’t see improvement in a few weeks with over-the-counter medications, call your doctor. As part of treating and preventing athlete's foot, clean and dry your feet thoroughly and wear clean socks every day. Unless specified, these products are not effective on the scalp or nails. Do not use on children under two years of age unless directed by a doctor.

What they are: Acne washes, cleansers, and scrubs are designed to remove dirt, oil, sweat, and makeup from skin with cleansing agents that also dry up pimples and kill acne-causing bacteria. Most acne washes contain benzoyl peroxide, salicylic acid, sulfur, or some combination of these ingredients.

Why to buy: These products are inexpensive, easy to use, and because they don’t remain on the skin after washing, they may be a gentler way to tackle mild acne.

Things to consider: If acne washes dry your skin too much, try using only once per day or every other day, rather than morning and night. For people with more serious acne, an acne wash alone may not be enough to get the condition under control. Combining an acne cleanser with a leave-on cream or lotion can help address this issue.

What they are: Acne masks are applied to the skin and left on for 10 to 20 minutes. They may be a cream or lotion, which dries on the skin, and then is rinsed off. They may contain benzoyl peroxide, salicylic acid, sulfur, clay, or some combination of these ingredients.

Why to buy: Acne masks can be used weekly to give an extra boost to your regular acne care routine. Some people find that using a mask once a week or so gives a deep clean that helps keep acne at bay.

Things to consider: Acne masks can be quite drying, so test a small patch of face skin before applying to your entire face. If you apply a mask and it stings a lot, wash it off right away.

What they are: Acne toners are liquid products that are applied to the skin using a cotton ball or pad. Toners are most effective if used after washing, but before applying lotions, moisturizers, or make up. They may contain a variety of ingredients, such as salicylic acid, plus non-oily moisturizing substances to help balance out the drying effects of other acne treatments.

Why to buy: Some people find that toners remove that last bit of acne-causing dirt and bacteria, and lessen the drying effects of other products. For people with mild acne, an acne toner alone may be enough to keep skin clear.

Things to consider: Toners can be more expensive than other acne products, and they require an extra step in your morning and/or evening routine.

What they are: Acne creams, gels, and lotions are applied to the skin and left on to offer maximum acne control. Acne pads are swiped over the skin and leave behind acne-fighting medication. Most contain benzoyl peroxide, salicylic acid, sulfur, or some combination of these ingredients.

Why to buy: These products are inexpensive and for more stubborn acne, they may be the most effective option. Acne creams, gels, lotions, and pads can be used to “spot treat” individual pimples or small breakouts, so the drying effect targets small areas.

Things to consider: Acne gels, creams, lotions, and pads are the most drying acne products. Benzoyl peroxide tends to be strongest, followed by sulfur and salicylic acid. Benzoyl peroxide often is found in teen acne products, since excess oil is often a problem during adolescence. Salicylic acid products are often formulated for adults.

What they are: Acne kits include several acne products in one unit, such as cleanser, skin-clearing treatment, and mild moisturizing lotion.

Why to buy: Acne kits offer convenient “all-in-one” product lines. If using a single acne product isn’t enough for your skin issues, or if you have side effects from single treatments, a kit may be worth a try. The combination of ingredients may be more effective than any one treatment alone.

Things to consider: Acne kits are an expensive acne treatment option and the multiple ingredients are more than many people need, or people may learn that only some of the products work for them. Ask about return policies before buying an expensive kit, and also find out if it’s possible to buy products individually.

What they are: Natural and herbal acne products use plants and herbs to treat and prevent acne. Ingredients found in natural acne products include white willow bark, tea tree oil, lemon grass, witch hazel, calendula, and goldenseal.

Why to buy: Natural acne products offer a way to manage acne without using synthetic chemicals. For acne-prone, sensitive skin, natural products may be less likely to cause irritation, redness, and peeling than conventional products. These products come in lotions, scrubs, spot treatments, toners, gels, and kits.

Things to consider: For tough acne, natural products may not be the most effective option. If you have allergies to specific herbs or plants, those ingredients may cause skin irritation.

What they are: After-sun skin care lotions tend to be thick, hydrating products that can seal moisture back into parched skin.

Why to buy: If you enjoy lots of outdoor time, an after-sun lotion may help keep your skin soft and supple.

Things to consider: These products come both with and without fragrance; if you have sensitive skin, opt for one without. These products are heavier than typical lotions, so use sparingly if you tend to have body acne.

What they are: After-sun skin care gels, wipes, and sprays typically are designed for sun-exposed or sunburned skin. They may contain aloe, chamomile, or other sunburn soothers.

Why to buy: Gels, wipes, and sprays are easier to apply than lotions and may be less irritating to sensitive sunburned skin. Gels, wipes, and sprays can be lighter than lotions, so they don’t tend to “seal in” the heat of sunburned skin—a good thing for anyone with a sunburn.

Things to consider: If your main goal is moisturizing, stick with a lotion.

What they are: Tan extenders are highly moisturizing and may contain ingredients that are designed to slow down the turnover and shedding of surface skin cells.

Why to buy: A tan is within the top few layers of skin; slowing down how quickly your body sheds those outer skin layers can lengthen the time you remain tan.

Things to consider: Some tan extenders come in bottles that look similar to sunscreens, but tan extenders are not designed to block the sun’s harmful rays. Read labels carefully to avoid accidentally using a tan extender as a sunscreen, which may lead to a nasty sunburn.
