Our Take
A potent, proven exfoliator that earns its shelf space and its price.
Sunday Riley's Good Genes is a high-potency lactic acid treatment built for visible results—not just promises. Lactic acid exfoliants have become the smart middle ground between gentle and aggressive: they work fast enough to matter, gentle enough to use regularly.
The Buying Guide
What to look at before you buy
01
Purified-grade lactic acid
The Active
Lactic acid is an alpha hydroxy acid (AHA) that dissolves the bonds between dead skin cells, revealing fresher skin underneath. This formula is high-potency, meaning it's concentrated enough to deliver visible results without requiring a prescription or professional application.
02
Serum texture with licorice brightener
The Ritual
Apply to clean skin. The serum absorbs quickly and works while you sleep or throughout the day. The addition of licorice root extract is meant to complement the exfoliating action by addressing the appearance of dark spots and uneven tone—turning a one-note exfoliant into a multi-step treatment in one bottle.
03
Cruelty-free, sulfate-free, paraben-free, vegan, and free of fragrance, gluten, soy, and phthalates
The Clean List
If you're building a serum routine with other actives or have skin sensitivities, the absence of common irritants and fragrances means fewer variables to manage. The vegan formulation appeals to those prioritizing ethical sourcing.
