A cruelty-free skincare based on skin condition (not skin type). There are 35 unique combinations.
The brand is vegan and blacklists more than two thousand toxic or potentially harmful ingredients.
Whether you experience dryness, acne, sagging skin or dullness - you can find a serum to target any skin concern.
Formulas were designed to be safe for all, even individuals with sensitive skin or pregnant women.
The beauty is how you can combine the serums, and apply them all at once, without the loss of individual efficacy.
