Retinol is among the most studied active ingredients for photoaging, but it isn’t an essential step, and there’s no specific age at which you have to start. Since 2024, new concentration limits have also been in place in Europe.

Dermatologically tested and clinically tested describe the framework in which the test was conducted, not the result. The five questions that turn a claim into useful information.

Collagen is not deposited or harvested: the term “banking” is a metaphor, not a mechanism. And the famous 1% annual decline is a simplification of the original source.

Face tape, mouth tape, chin straps, and masks: the morning shed promises to wake us up looking more beautiful. Some practices serve a purpose, others have a temporary effect, and others have no evidence behind them.
