Get pro tips like products you can skip and the sneaky cancer signs you should never ignore
Key Takeaways
- Dermatologists say over-exfoliating can worsen dryness and fine lines after age 50.
- Skin cancer can appear in unexpected places, including under nails and on the vulva.
- Stress, diet and sunscreen habits all play a major role in skin aging and health.
Dermatologists are specialists best known for inspecting iffy moles, calming rashes and erasing fine lines. But they also see hidden clues the rest of us miss about our skin health. Plus, they’re bursting with expert insights that help us look our best. The problem? They rarely get the chance to share these gems with patients. So, we asked top dermatologists to spill the surprising skin secrets they want every woman to know.
Dermatologists’ 12 best-kept skin secrets
The key to radiant, healthy skin after 50? Learning from this doctor-backed advice:
Daily face scrubs backfire
Cutting back on everyday scrubs, peels or acids isn’t just good for your wallet—it also makes your face more radiant at this age, says Debra Jaliman, MD, New York City cosmetic dermatologist and author of Skin Rules. As estrogen declines around 50, your skin barrier becomes more delicate. The result? “Excess exfoliation leads to irritation, dryness and redness, and can actually make fine lines more noticeable.” Limit exfoliants one to three times a week and you’ll avoid those downsides while still getting the glow-boosting benefits. Prefer a gentle manual exfoliator over scrubs or peels? Consider Cleanlogic Sensitive Skin Dual-Texture Facial Mitts.

Topical collagen isn’t worth it
Want a firmer, plumper look? Don’t bother splurging on creams that list collagen on the label. “They’re a waste,” insists Dr. Jaliman. “Collagen molecules are too big to penetrate the skin, so they don’t rebuild collagen or restore firmness,” she explains. For real results, she recommends looking for peptides, which are more easily absorbed and stimulate the skin to make more of its own collagen.
This hidden gem softly brightens
If you’re looking for a more even complexion, there’s one ingredient worth adding to your routine: azelaic acid. It doesn’t get the hype of retinol or vitamin C, but it gently tackles several concerns at once. “Azelaic acid is very underrated,” says Dr. Jaliman. “It improves brown discoloration, reduces redness, evens tone and smooths texture all without irritation.” Best of all, many azelaic acid creams are inexpensive, such as The Ordinary Azelaic Acid Suspension 10% Cream, which costs around $12 at Ulta.
A too-hot rinse saps moisture
Simply switching to lukewarm water when washing your face gives you a softer, smoother appearance, says Dr. Jaliman. “Hot water strips the skin of its natural oils and worsens dryness,” she explains. Another smart tweak: Apply a rich moisturizer while your skin is still slightly damp. “This helps lock in hydration.”
Unique clues may signal skin cancer
You’ve probably heard about the ABCDE rule for checking moles—look for asymmetry, borders that are irregular, colors that vary, diameter that’s wider than a pencil eraser and evolving in size or color over time. But those aren’t the only red flags, says Maya Thosani, MD, medical director and skin cancer expert at Modern Dermatology in Scottsdale, Arizona. She suggests also watching for these lesser-known red flags:
- The ‘ugly duckling’ spot: “This is when one mole seems out of place and doesn’t look like any others you have,” she says. Dermatologists often use this trick to catch early melanomas that don’t appear obviously abnormal.
- A ‘pimple’ that won’t go away: If the same bump keeps returning in the same spot and bleeds easily, it could be a basal cell carcinoma—the most common type of skin cancer, she notes.
- Your wound won’t heal: A curling iron burn, gardening scratch or other injury that lingers for more than a month deserves a check. “Skin cancers like basal cell or squamous cell carcinoma can form in a scar as it’s healing, especially if that area gets sun exposure.”
- A dark stripe under one nail: An isolated streak or band on one fingernail—especially if it has multiple colors—can be a sign of melanoma lurking underneath, she shares.
Melanoma can show up ‘down there’
When you think about checking for suspicious spots, you probably focus on your face, neck, arms, legs and back. What rarely gets mentioned: “You can get skin cancer, like melanoma, on your vulva,” says dermatologist Melissa Mauskar, MD, founder and director of the Vulvar Health Program at UT Southwestern. While rare, it can be more dangerous because it’s often caught late. So, regularly take a look, then make sure to mention any dark spots, color changes or growths to your doctor.
Ask us about genital itching
Have irritation on your vulva, but tests come back clear from your gynecologist? Head to a dermatologist next, recommends Dr. Mauskar. “People don’t often think of seeing a dermatologist for vulvar symptoms, but I usually see patients that have been to two or three other doctors first,” she shares. Because vulvar skin behaves just like the skin on the rest of your body, conditions like eczema or psoriasis can show up there too—and they’re often treatable once you visit the right specialist.
Sunscreen is for indoors too
Broad-spectrum SPF isn’t just for when you’re spending time outside. It’s also important to apply it when you’re inside rooms with windows or driving on sunny days. “While standard glass blocks UVB rays (which cause sunburns), it allows most UVA rays to pass through, contributing to premature aging and skin cancer,” says Erica Lee, MD, dermatologist and Mohs surgeon at Memorial Sloan Kettering Cancer Center. Choosing broad-spectrum sunscreen ensures you’re protected from both types of rays, no matter where you are. Two we like: Vacation Classic Lotion SPF 50 and Burnd SPF41.
Most miss key sunscreen spots
Even the most diligent SPF users tend to forget a few places, says Dr. Lee. “Patients often overlook applying sunscreen to the lips and around the eyes, ears and neck.” Since these locations get plenty of sun, they’re common sites for skin cancer, she points out. Remember to apply SPF lip balm and give these body areas a swipe of sunscreen.
Spray sunscreen can cause burns
It may seem convenient to put on SPF by just pressing a button, but dermatologists say spray sunscreen comes with a hidden hazard: If you’re near an open flame—like a grill, fire pit or even a candle—it can ignite on your skin if it hasn’t completely dried, leading to serious burns. The reason? “Spray versions of sunscreen often contain alcohol and propellants that make them quick-drying and easy to apply, but these ingredients can be flammable until they fully evaporate,” explains Dr. Jaliman. To stay safe, she advises using a lotion-based sunscreen when around heat sources since they don’t carry the same flammability risk.
Food can lessen—or worsen—sun damage
“The way your skin responds to the sun is influenced by what you eat,” says dermatologist Jen Haley, MD, host of the Radiance Revealed Podcast. Diets high in processed foods (like candy, pastries and white bread) can worsen DNA damage from UV radiation, while foods rich in polyphenols and carotenoids (including berries, tomatoes, carrots, leafy greens and green tea) help protect against its harmful effects, she explains. One key reason: Sugar and other highly-processed ingredients tend to increase inflammation, which slows skin repair. But antioxidants in plant-based foods calm inflammation and support the skin’s natural defenses. While salads and iced tea don’t replace sunscreen, they can give your skin an extra boost of protection from the inside out.
Sudden sensitivity may be stress
Ever had an unusual reaction to a moisturizer, serum or cleanser you’d used for years without issue? Your nervous system may be temporarily overwhelmed, says Keira Barr, MD, psycho-dermatologist and author of The Skin Whisperer. “Stress lowers the skin’s sensory threshold, so products that used to feel fine may suddenly make your skin sting, flush or itch,” she explains. Fortunately, you can reverse this reactivity by dialing down stress. A calming tactic she suggests: After cleansing at night, gently rest your palms over your face for 10 seconds. “This activates nerve fibers that send a signal to parts of the brain involved in safety and bonding, slowing your heart rate and lowering the stress hormone cortisol.”
