How every review works

Not a first impression.
A documented experiment.

  1. Purchase & photograph

    Every product is self-purchased. Unboxing, texture, packaging — all photographed before first use at consistent lighting and angles.

  2. Ingredient breakdown

    Full INCI list analysed. Key actives identified, concentrations estimated, mechanism explained against available evidence.

  3. Four-week skin log

    Weekly photographs under identical lighting. Honest notes on what changed, what didn't, and the likely reason why.
