Dermatologists Warn About New TikTok ‘Over-Seruming’ Trend

A new skincare habit popularized on TikTok is causing growing concern among dermatologists worldwide. Known as the “over-seruming” trend, it encourages users to layer multiple serums—sometimes five to seven products—in a single routine, promising instant glow, poreless skin and fast results. While the videos have gained millions of views, experts say this trend may do more harm than good.

The obsession with serums is not new, but TikTok’s fast-paced beauty culture has amplified it to extremes. Videos often promote mixing actives like vitamin C, retinol, niacinamide, AHA/BHA acids and peptides in one routine without understanding how these ingredients interact. Dermatologists emphasize that combining so many potent formulas can lead to irritation, redness and a damaged skin barrier.

Skin specialists report a noticeable rise in patients experiencing sensitivity, breakouts and burning sensations—symptoms directly linked to product overload. According to experts, many serums contain high concentrations of active ingredients that are designed to be used strategically, not all at once. When layered excessively, these ingredients begin competing, canceling out benefits or triggering inflammation.

Another concern is that many creators promote a one-size-fits-all routine, which ignores skin type differences. What works for oily or acne-prone skin may be harsh for dry or sensitive skin. Dermatologists advise that effective skincare should be personalized, not copied from influencers who often have access to professional treatments off-camera.

The trend also contributes to unnecessary spending. Serums tend to be some of the most expensive products in a skincare routine. Many young users, influenced by viral content, purchase multiple actives they don’t need, leading to product waste and financial strain.

Dermatologists recommend adopting a “less is more” philosophy. A simple routine—cleanser, one well-chosen serum, moisturizer and sunscreen—often delivers better long-term results than stacking multiple actives. They also stress the importance of patch testing and introducing new products slowly to avoid irritation.

The rise of the over-seruming trend highlights the growing impact of beauty influencers on consumer habits, but it also serves as a reminder that expert advice should take priority when it comes to skin health. Skincare is a science, not a viral challenge, and dermatologists hope users will think twice before applying every serum they own in pursuit of instant results.
