It's no secret that social media content is designed to be attention-grabbing. Yet, we still sometimes make skin care decisions based purely on testimonials or "before" and "after" photos we see online.
"There is so much skin care information online now, and it can be genuinely overwhelming," says MU Health Care dermatologist Jordan Parker, MD. "People are being shown thousands of products, routines, supplements, devices and hacks, often with very confident claims behind them."
To help you make sense of some of the skin care claims found online, Dr. Parker is sharing her thoughts on common skin care myths she hears from her patients.
Myth #1: Topical Corticosteroids Are Toxic
Fact: When Used Correctly, Topical Corticosteroids Are Safe and Effective
Topical corticosteroids are not a new skin care treatment, and they are effective for managing many skin conditions. The Food and Drug Administration (FDA) has approved corticosteroids for many inflammatory dermatologic disorders, including:
"The reality is that topical steroids are some of the most well-studied medications we use in dermatology," Dr. Parker says. "But like any medication, they can have side effects, especially if the wrong strength is used for too long."
Dr. Parker suggests only using topical steroids on areas of active rash and avoiding prolonged daily use unless specifically instructed. After two weeks of use, it's a good idea to take a break or transition to a non-steroidal maintenance option if needed.
"Different conditions require different regimens," Dr. Parker adds. "You should always use steroids under the supervision of a dermatologist and follow the plan they prescribe."
Myth #2: Topical Steroid Withdrawal Happens to Anyone Who Stops Using Topical Steroids
Fact: Topical Steroid Withdrawal Only Happens After Prolonged or Inappropriate Use of Topical Corticosteroids
Topical steroid withdrawal (TSW), also known as red skin syndrome, is an adverse reaction that can occur after stopping use of topical corticosteroids. The symptoms of TSW include:
- Burning
- Itching
- Peeling
- Redness or discoloration
- Swelling
"The symptoms being discussed online under the label of TSW are real symptoms," Dr. Parker says. "But one of the biggest misconceptions I hear is that TSW can happen from any use of topical steroids, even short courses used appropriately. There is no data supporting that — and TSW is rarely seen when topical steroids are used under the direction of a physician."
In some cases, the original skin condition can flare up when you stop using topical steroids — creating symptoms that may be mistaken for withdrawal symptoms.
"A rash that occurs after stopping a topical steroid does not automatically mean the steroid caused the problem or that you have TSW," Dr. Parker says. "It may simply mean that the original disease needs a longer-term management plan."
Myth #3: Wearing Sunscreen Can Cause Skin Cancer
Fact: Sunscreen Is Proven to Prevent Cancer, Not Cause It
It's understandable to be concerned about the dangers associated with sunscreen ingredients. However, there is no data suggesting that sunscreen causes cancer. There is overwhelming data proving that the sun causes most skin cancers and that sunscreen can protect you.
"There were old studies suggesting a connection between sunscreen use and melanoma, but no clear evidence," Dr. Parker says. "There have also been social media scares about certain sunscreens containing benzene — a toxic chemical released from automobile emissions, burning coal and oil." But while trace amounts of benzene have been reported to contaminate some sunscreens — which were recalled — benzene is never an intentional ingredient in sunscreen.
If you still have concerns, you can choose to use a mineral sunscreen — they typically have fewer ingredients and are not absorbed into the skin. You can also prioritize nonchemical sun protection, such as covering your skin, wearing hats and sunglasses and limiting your exposure.
Myth #4: Getting a "Base Tan" Can Protect You From Skin Cancer
Fact: A "Base Tan" Increases Your Risk for Cancer
There is no safe way to get a tan from the sun. In fact, any tan — even if your skin doesn't burn — is a sign of sun damage. Ultraviolet A (UVA) rays from the sun penetrate deep into the skin's thickest layer and cause DNA changes to skin cells. That's what makes you appear tan. But those cellular changes are also damaging and can lead to skin cancer.
Getting a "base tan" from a tanning booth increases your cancer risk even more. Tanning beds emit 12 times more UVA rays than natural sunlight.
"Some people think that getting a 'base tan' from a tanning booth before vacation will allow them to avoid a sunburn or sunscreen use," Dr. Parker says. "But a base tan, whether from a tanning booth or the sun itself, essentially provides the same protection as SPF 4 and also significantly increases your skin cancer risk."
The best way to get tan is to use sunless tanners. But you'll still need to take steps to protect your skin from UV rays.
Myth #5: If a Product is "Natural," It Is Safe for Your Skin
Fact: Natural Skin Care Products and Supplements Can Be Unsafe
When you're trying to avoid skin care that is toxic or unsafe, products labeled "natural" or "clean" may seem like a good alternative. The problem is that the FDA provides no accepted definition of "clean" or "natural." Natural products can still contain active ingredients that are irritants and allergens. Essential oils, fragrance, botanical extracts and exfoliating acids can all be found in "natural" skin care products, and all can cause skin issues.
"Just because something is 'natural' does not automatically mean it is safe or useful," Dr. Parker says. "Poison ivy is all natural, but that doesn't mean you should use it on your skin."
She also suggests being cautious with supplements — even if they claim to keep skin moisturized, reduce inflammation or plump wrinkles. Natural supplements are not well-regulated and can interact with medications or worsen certain conditions.
"Biotin, for example, can interfere with some lab testing," Dr. Parker says. "Other supplements have been known to affect bleeding risk, liver function, hormones or acne."
Tips for Navigating Social Media Skin Care Advice
Social media and other online information sources can be a great source of general skin care tips. However, it is rarely a reliable place to get medical advice.
"A lot of dermatology content online is simplified, exaggerated or designed to sell a product," Dr. Parker says. "My advice is to be curious, but skeptical."
Every time you encounter skin care advice on social media, Dr. Parker recommends asking these questions:
- Who is providing the advice? Are they a doctor, board-certified dermatologist or qualified medical professional, such as a physician assistant or nurse practitioner?
- Is the post trying to sell a product or service?
- Does the post make big or extreme claims, such as "this cures EVERYTHING" or "NEVER use this product"?
"A health care professional can determine what is actually evidence-based, what is safe and what may be unnecessary, irritating or harmful," Dr. Parker says. "Your best bet is to use social media as a source of ideas, not answers."
