If you remember at least three objects or cultural references from the 90s/2000s, you should start using retinol for your skin.

The advice uses a generational marker (nostalgia) to suggest introducing retinol into a wellness routine, which corresponds to the age range where cell turnover naturally begins to slow down. Retinol, a derivative of vitamin A, is one of the most documented active ingredients in dermatology for stimulating collagen synthesis and improving skin texture (Meta-analysis, Journal of Clinical and Aesthetic Dermatology). While the ingredient's efficacy is solidly established by scientific research, the idea that the need begins at a specific age based on cultural memory is a marketing simplification. There is no scientific evidence linking the ability to remember an object like a Furby to the precise biological state of the skin. Furthermore, tolerance to retinol is highly individual and depends more on the state of the skin barrier than on the year of birth. The argument is therefore an effective targeting strategy, but it is scientifically arbitrary.
