Looksmaxxing: The Viral Trend Dermatologists Are Worried About

What looksmaxxing actually is

If you have a teenager in your life, you've probably heard the term — or seen the TikTok videos. Looksmaxxing is the practice of optimizing your appearance through systematic effort: skincare layering, facial exercises, specific postures, diet protocols, sleep positioning, and in more extreme corners of the internet, practices like "mewing" (tongue posture) and "bone smashing" (striking facial bones to supposedly reshape them).

The skincare side is where most teenage girls enter. The pitch is reasonable enough: use evidence-based actives to get the best possible skin. The execution, copied from adult routines on TikTok, is where things go wrong fast.

What the research found about teen skin and TikTok routines

A 2025 Northwestern University study confirmed what pediatric dermatologists had been reporting anecdotally for two years: TikTok-influenced skincare routines are actively harming teen skin. Contact dermatitis, chronic barrier disruption, and increased UV sensitivity were among the documented outcomes in girls following multi-step active routines.

The problem is not that teenagers are interested in skincare. It's that the products going viral — retinoids, AHAs, vitamin C serums, exfoliating toners — are formulated for adult skin dealing with adult-skin problems like sun damage, fine lines, and hyperpigmentation. Teenage skin doesn't have those problems. It has its own biology: higher sebum production, faster cell turnover, and a barrier that's more sensitive to pH disruption than most product marketing acknowledges.

Where looksmaxxing crosses from skincare into something more serious

Skin damage is the visible part. The harder-to-see harm is psychological. When 68% of teen girls link their skincare routine to appearance surveillance rather than skin health, we're not talking about self-care anymore.

The body dysmorphia overlap is real. Looksmaxxing forums and comment sections grade users' "current level" and prescribe increasingly extreme interventions: from retinol at 13 to jaw exercises to, in the most extreme communities, deliberate facial bone stress. These are not fringe behaviors. They're part of a documented subcultural pipeline where the entry point is a vitamin C serum and the exit can be body dysmorphic disorder.

What teen skin actually needs

Here's the honest version: healthy teenage skin requires almost nothing. The three steps that cover the vast majority of teen skin needs are a gentle, non-stripping cleanser, a basic moisturizer, and SPF. That's it. Starting SPF habits at 13 is the single most impactful long-term skin decision a teenager can make — not because of immediate results, but because UV damage accumulates invisibly for decades before it shows up as pigmentation and structural aging in the 30s.

Acne changes the calculation slightly. Benzoyl peroxide (2.5–5%) and salicylic acid (0.5–2%) have solid evidence for teen acne. But these should be targeted treatments, not daily full-face applications — and if acne is moderate to severe, a dermatologist visit is far more useful than any routine a TikToker can prescribe.

• ✓The 3-step rule: Gentle cleanser + moisturizer + SPF 30–50. Everything else is optional and most of it is unnecessary for healthy teenage skin.
• ✓Retinoids are not for teenagers: Prescription tretinoin for severe acne is a dermatologist decision. Over-the-counter retinol in a daily routine? Not appropriate for skin that already has fast cell turnover.
• ✓Acids at any concentration require caution: AHAs (glycolic, lactic) and BHAs (salicylic) can be useful but should not be daily staples in a teen routine — and never layered with other actives.
• ✓Patch test everything: Teen skin is reactive. Any new product should be tested on a small area for 5–7 days before full-face use.

What to tell your daughter (or yourself, if you're the teenager)

The goal of looksmaxxing content is engagement, not skin health. Creators benefit when you buy more products and try more things. Dermatologists benefit when your skin is actually healthy.

Those are not the same incentive structure.

• →Ask your dermatologist or OB-GYN before adding any active ingredient — retinol, acids, or vitamin C — to a teen routine.
• →If a routine is causing tingling, redness, or flaking that wasn't there before: that's barrier disruption, not "purging." Stop the offending product.
• →If skincare is becoming a daily source of anxiety or self-comparison, that's worth a conversation — with a parent, a counselor, or a doctor.
