What Dermatologists Say About TikTok Skincare Trends
In recent years, TikTok has become a powerhouse for beauty influencers pushing everything from quirky DIY remedies to multi-step routines promising radiant skin. But how do dermatologists weigh in on these trends? Let’s unpack what is backed by science—and what should be approached with caution.
The Role of TikTok in Skincare Trends
TikTok has made skincare more visible and accessible than ever. According to one industry analysis, 64% of individuals aged 18–34 turn to TikTok for beauty advice, rivaling traditional professionals.
Dermatologists acknowledge that social platforms can raise awareness—empowering users to pay attention to skin health and ingredient transparency—but they warn that “misinformation travels six times faster than accurate information”. With minimal regulation, anyone can share unverified advice without consequences.
Dermatologist-Approved TikTok Trends
Skin Cycling
This four-day routine alternates between chemical exfoliation, retinoid application, and recovery days. Dermatologists widely endorse it as a balanced approach to combining potent ingredients without overloading the skin barrier.
Slugging
Applying a thick layer of petroleum jelly over moisturized skin overnight is effective in retaining hydration and repairing the skin barrier—making it especially beneficial for dry, irritated skin. However, it’s not recommended for acne-prone or oily skin due to potential breakout risk.
LED Light Therapy (at-home devices)
Dermatologists generally support this trend. When choosing a device, matching the wavelength to your skin needs (e.g., red light for signs of aging, blue light for inflammation) is key.
7-Skin Method
This South Korean–inspired trend involves layering toner up to seven times to hydrate. Experts say it may benefit dry skin—but can overwhelm sensitive or oily skin.
Trends Dermatologists Warn Against
Face Taping & Chin Wraps
Often promoted for anti-aging or jawline sculpting (e.g., the viral “morning shed” routines), dermatologists call these methods ineffective and possibly irritating. They can also contribute to plastic waste and provide merely temporary effects. Better alternatives? Retinoids, sunscreen, and medically advised treatments.
Pore Vacuums
While satisfying to watch, these devices can damage skin, break tiny blood vessels, and exacerbate acne. They don’t address root causes. Gentle exfoliation and prescription options are more effective and less risky.
DIY and One-Size-Fits-All Hacks
TikTok trends like using lemon juice, toothpaste, or raw garlic as skincare can compromise your skin’s barrier and cause irritation, burns, or infections. Influencer routines often lack essential context—like user skin type or product ingredients—so they may not be suitable for everyone.
DIY Mole Removal, Self-Injectables, Melanotan Sprays
These trends are downright dangerous. Attempts at removing moles or skin tags without medical oversight can hide signs of skin cancer or lead to infections. Self-injecting fillers or Botox, similarly, risks serious complications—including blindness and vascular damage. Melanotan nasal sprays, used for tanning, are unregulated and may increase melanoma risk.
Volufiline (Plant-Derived Plumping) Hype
Selling points tout it as a topical filler alternative, but clinical evidence is minimal. Dermatologists are skeptical and note that maintenance is required—and using proven in-office treatments may be more effective and safer.
Anti-Sunscreen Trends
By far one of the most harmful, some influencers encourage ditching lotion in favor of “natural” exposure or homemade alternatives. Dermatologists and public health experts strongly oppose this, citing increased risks for premature aging, sunburn, and skin cancer. Their recommendation: stick with broad-spectrum SPF 30+, especially mineral-based options, and don’t fall for misinformation about ingredients like oxybenzone.
Why Teens Are Especially at Risk
A study in Pediatrics analyzed 100 TikTok routines by users aged 7–18 and found that routines averaged 11 active ingredients—and alarmingly, only 26% included sunscreen. The developing skin of children and teens is more sensitive and prone to allergic reactions. Dr. Hallie McDonald advises simplifying routines—fragrance-free cleanser, moisturizer, and mineral SPF—and consulting a dermatologist for issues rather than chasing online trends.
How to Navigate TikTok Skincare Safely
Here’s a dermatologist-approved checklist before trying any TikTok skincare trend:
Check for Scientific Support – Is there peer-reviewed research or clinical backing?
Know Your Skin – Consider your specific skin type and conditions; what works for one may harm another.
Patch Test First – Test new products or DIY treatments on a small area before full-face application.
Watch for Red Flags – Emergency trends, claims of instant results, or heavy use of harsh ingredients should raise concern.
Prioritize Basics – Foundational skincare—gentle cleansing, hydration, and daily SPF—is the real key.
Consult a Professional – Always consult a board-certified dermatologist if you're unsure or dealing with skin problems.
Final Thoughts
TikTok offers a double-edged sword for skincare enthusiasts: on one hand, it's driving awareness and transparency. On the other, it’s become a fast lane for misinformation and risky practices. Dermatologists encourage embracing trends like skin cycling or slugging (for appropriate skin types), while steering clear of untested DIY methods, self-injections, or misinformation that can compromise skin and health.
In the end, nurturing healthy skin isn’t about flashy routines—it’s about consistency, personalization, and science-backed decisions.
