How the recommendation engine works
Product role first, brand second
Every named product is tagged by role, skin-type fit, goal, sensitivity and active family. The engine scores those tags against your answers, excludes retinoids when the cautious pregnancy setting is selected and separates exfoliating or retinoid treatment nights from recovery nights.
A favourite brand can be prioritised without forcing it into every step. That matters because a range may make the right cleanser or sunscreen for you without making the strongest treatment for your main goal.
