Made for skin you don't have yet
Retinol products are built to treat wrinkles and sun damage, which teen skin doesn't have. Your skin is thinner and more reactive than adult skin, so what you actually get is the side-effect list: redness, peeling, stinging, and extra sun sensitivity, in exchange for basically nothing. If you have acne, adapalene is the retinoid with real evidence for you. Wrinkle products can wait a decade or two. They'll still be there.

More steps, more problems
Researchers actually studied the skincare routines young creators post on TikTok. The average routine had 6 products costing about $168 (some over $500), the most-viewed ones layered up to 21 potentially irritating active ingredients, and only about a quarter included sunscreen. Every extra product is another chance at irritation or a new allergy, all stacked on the same face at once. Three boring steps beat ten exciting ones. It's not even close.
