Tretinoin 'glow-up' claims: what the before-and-afters don't tell you

What did @alexiseliavv actually say?

Honestly? Nothing about tretinoin at all. The transcript is rap lyrics, not skincare commentary. The video's claims live entirely in the caption and the before-and-after images, where @alexiseliavv says they are "in love with tret" and implies the results speak for themselves. There is no verbal explanation of how tretinoin works, what concentration was used, or how long the treatment lasted. That matters, because a lot of the most misleading tretinoin content on TikTok lives in the visual framing, not the words.

The caption credits tretinoin directly for visible skin changes. The hashtags position this as a skincare routine recommendation with 184.9K views pulling in users who may interpret the post as clinical guidance. Without any spoken context, viewers are left to fill in the blanks themselves, and they often fill them in wrong.

Does the science back up the idea that tretinoin works?

Yes, and this is one of the few areas in dermatology where the evidence is genuinely solid. Tretinoin (all-trans retinoic acid) has decades of randomized controlled trial data behind it. Weinstein et al. (1991, Journal of the American Academy of Dermatology) demonstrated statistically significant improvements in fine lines, skin texture, and hyperpigmentation versus vehicle in a 48-week trial. Kligman et al. (1986, JAMA) established the foundational mechanism: tretinoin accelerates epidermal cell turnover and stimulates collagen synthesis in the dermis.

More recent work by Mukherjee et al. (2006, Clinical Interventions in Aging) reviewed over 700 studies and confirmed tretinoin as the best-evidenced topical retinoid for photoaging. The catch is that visible results typically require 12 to 24 weeks of consistent use, and the "retinization" period involves peeling, redness, and irritation that before-and-after posts rarely show. If the results in this video are real, they are real because the science is real, not because of anything special about posting it on TikTok.

What did they get wrong, or right?

Credit where it is due: using tretinoin and sharing results is not inherently misleading. The problem is the context gap. Before-and-after skin posts without disclosing concentration, frequency, skin type, concurrent products, or timeline are a known driver of unrealistic expectations. A viewer with sensitive skin who starts tretinoin after seeing this and skips the slow-titration phase is going to have a bad time.

There is also the category mismatch to flag. This video was tagged under TRT (testosterone replacement therapy) in the platform's classification system, which makes zero clinical sense. Tretinoin is a topical retinoid. It has no relationship to testosterone or hormone optimization. That miscategorization could theoretically push this content toward audiences researching hormone therapy, where the framing of "dramatic transformation" lands very differently.

What is missing: no mention of sun sensitivity (tretinoin substantially increases UV vulnerability), no disclosure of whether this was prescription-strength or an over-the-counter retinol conversion, and no acknowledgment that results vary significantly by Fitzpatrick skin type and photoaging severity.

What should you actually know before trying tretinoin?

Tretinoin is prescription-only in the United States and most regulated markets. It is not the same as over-the-counter retinol, which must be converted to retinoic acid by skin enzymes, making it slower and less potent. Compounded tretinoin formulations exist and are used clinically, but they should not be assumed equivalent to brand-name products like Retin-A or Altreno without provider guidance.

The standard clinical recommendation is to start low (0.025%) and increase slowly, applying a pea-sized amount to dry skin every two to three nights before building to nightly use. Daily broad-spectrum SPF 30 or higher is non-negotiable while using tretinoin. Avoiding it during pregnancy is also non-negotiable, as retinoids are teratogenic. A telehealth provider can assess whether tretinoin is appropriate for your skin type and history, which is genuinely the right starting point before copying a TikTok result.
