Finally something that actually matches my skin.
I've tried every "personalized" routine on the market and most are just quizzes. The DNA report explained exactly why my old products were failing me — within 6 weeks my redness was almost gone.

Worth every penny for the report alone.
Skeptical at first but the science checks out. Kit was easy, results came in two weeks, formula was nothing like what I would've picked myself. My dermatologist was impressed.

Solid product, great support.
First formula was a touch heavy for my skin type. Emailed support, they reformulated for free. Second batch is perfect. Genuinely impressed by their stand-behind-the-promise approach.
