Sunday Riley Good Genes lactic acid serum — 1.0 oz | exfoliating, brightening treatment

Good Genes All-in-One Lactic Acid Treatment is a high-potency lactic acid serum that exfoliates surface dead skin to reveal smoother, brighter-looking skin.

Sunday Riley Good Genes is a lab-backed exfoliant formulated around purified lactic acid to lift away dull, pore-clogging cells and accelerate visible radiance. Fortified with licorice and other supportive botanicals, this treatment is designed to refine texture, visually plump fine lines, and help fade the look of discoloration when used consistently. The formula is fragrance-free, vegan, and cruelty-free, fitting into modern, clean routines for many skin types.

How does Good Genes improve skin texture and radiance?

The serum uses purified lactic acid to loosen bonds between dead skin cells, enabling quicker surface renewal and a more luminous appearance. As outer layers shed, skin reflects light more evenly and feels smoother to the touch.

• High-potency lactic acid for immediate exfoliation
• Licorice extract supports brighter-looking tone
• Visibly softens roughness and refines pore appearance

When will I see results for lines, texture, and dark spots?

Some changes—like smoother texture and an instant glow—can be noticed after the first uses, while cumulative improvements to discoloration and fine lines develop with regular use. Consistent application as directed helps the formula deliver its targeted benefits over weeks.

• Immediate: fresher look and softer surface
• Short term: improved texture and plumped appearance of fine lines
• With continued use: reduced look of hyperpigmentation

How should I incorporate this lactic acid treatment into my routine?

Apply on clean, dry skin—typically once daily in the PM or as tolerated—after cleansing and before heavier creams or oils. Because lactic acid increases sun sensitivity, pair the treatment with daytime SPF and introduce it gradually to avoid irritation.

• Use after cleansing, before moisturizer
• Start every other night if you have sensitive skin
• Always apply daily sunscreen while using exfoliating acids

Is this product suitable for my skin type and concerns?

Good Genes is formulated for broad compatibility across skin types and ages, though those with very sensitive or compromised skin should patch-test and consult a dermatologist if unsure. The formula avoids common irritants like synthetic fragrance and parabens to reduce mismatch risks.

• Appropriate for oily, combination, normal, and dry skin types
• Fragrance-free and free from sulfates, parabens, and phthalates
• Vegan and cruelty-free with clinically-backed ingredients

Who is this for: Sunday Riley Good Genes is designed for anyone seeking a reliable, science-forward exfoliating treatment to refresh dull skin, refine texture, and promote a more even-looking complexion. It’s a practical choice for users who want a concentrated lactic acid serum within a clean-beauty framework—ideal for those prioritizing visible radiance and texture improvements while sticking to fragrance-free, cruelty-free formulations.
