10 best pieces of skin-care advice dermatologists gave us this year
"No matter your hair type or texture, massage your hair and scalp with hair oil once a week," says Michele Green, MD, a board-certified dermatologist in New York City. That's because when you massage your scalp, you're increasing blood circulation which promotes the distribution of nutrients throughout the scalp and hair. "This step in a hair care regimen helps strengthen hair follicles and promotes scalp and hair health."
There is never, ever a need to get a “base tan” before vacation to avoid burning on the beach. “Any tan is your body’s response to DNA damage by UV radiation,” warns Jennifer Holman, MD, a Texas-based board-certified dermatologist who was diagnosed with skin cancer in her early 20s. “The way I explain it to patients is that a base tan is like smoking five cigarettes a day to get ready for a vacation when you’ll smoke twenty cigarettes a day.”
"The area around the eyes is the most sensitive part of your skin because it's so thin. You can cause an abrasion very easily," says Lynn McKinley-Grant, MD, a board-certified dermatologist in Washington DC. "If you find you're rubbing your eyes a lot, then you might have an allergy to something either environmentally in the air or nail polish, mascara, your eye cream, or even eye drops." Plus, aggressive rubbing can lead to darkening of the skin around the eyes "and it can cause a thickening of the skin, but not in a pretty way," she says. "We call it lichenification of the skin with a lot of wrinkles in it that look sort of like a tic-tac-toe board with little lines going vertically and horizontally."
"Next time you get your gel mani, don't forget to bring your sunscreen along," says Adeline Kikam, DO, a board-certified dermatologist. "The UV light used to harden the nail polish can potentially increase the risk of skin cancer and cause premature aging. Nail lamps mainly emit UV radiation, it's one of the most DNA-altering penetrative wavelengths, and the number one culprit in accelerating premature aging and also contributes to skin cancer."
"If your acne is getting worse, I wouldn't start using multiple products all at once," says Marisa Garshick, MD, a board-certified dermatologist in New York City. "If you're going to start a new skin-care product, make sure you're only doing one at a time. Give it another three weeks, but don't panic and try everything that you see in the drugstore aisle. Make sure that you're thoughtful in your approach and just use one new thing at a time. Maybe start by introducing a new cleanser. So for some people who are already using a prescription active ingredient and maybe a gentle cleanser, it's possible that they need a medicated cleanser in conjunction with that. But don't use that plus an exfoliant plus a toner all at the same time."
"There's a known phenomenon called the Koebner Phenomenon, where any type of trauma—so cuts, scrapes, even self-induced trauma, like a scratch or a rubbing—can flare your psoriasis," says Ivy Lee, MD, a board-certified dermatologist in Pasadena, California. She explains that oftentimes patients with mild psoriasis will try to get rid of it by scrubbing the area with a loofah or pumice stone, and will then find that the scales got worse or spread to a larger area. "And that's what we call the Koebner Phenomenon, where if you manipulate, scratch, or abrade your psoriasis, it can spread."
When opting to get filler, you can get permanent filler that sticks around or temporary filler that uses ingredients like hyaluronic acid that break down over time and require re-injection. Ranella Hirsch, MD, a board-certified dermatologist in Massachusetts won't go near the former. "Permanent ones like certain silicones and others carry the risk of delayed and often permanent complications," says Dr. Hirsch. "While no procedure is entirely without risk, those of temporary fillers tend to be more immediate, temporary, and often reversible."
"Antiperspirants contain aluminum salts which are ingredients used to block the sweat glands and reduce sweating," says Heather Woolery-Lloyd, MD, a board-certified dermatologist in Miami. "Most antiperspirants also contain ingredients to eliminate or mask odor too, but the primary aim of an antiperspirant is to reduce sweat." She adds that it's totally okay to use your regular antiperspirant on your arms, legs, chest, stomach, and wherever else you may need it—the only exceptions are your face and your intimate areas.
When your skin is dry, it's tight. And when it's tight, it's easier for fine lines and wrinkles to settle in and stick around. So keeping your face moisturized can help stave off premature signs of aging, explains Jeanine Downie, MD, a board-certified dermatologist in Montclair, New Jersey, and the founder of Image Dermatology. "I wish that I had moisturized more when I was younger," she says.
"Niacinamide has calming and anti-inflammatory properties, which counteract the effects of stress hormones on the skin," says Shirley Chi, MD, a board-certified dermatologist in Southern California. "Stress hormones increase oil production on the skin, so decreasing inflammation makes your skin less oily." That's because the glands that create oil and sebum have hormonal receptors on them. So calming your skin and protecting it from stress hormones helps to normalize the oil glands.
