Sunday Riley Good Genes Lactic Acid Serum 1.0 oz — Brightening, Exfoliating Treatment for Smoother Skin

Good Genes All‑In‑One Lactic Acid Treatment is a concentrated lactic acid serum that exfoliates surface dead skin cells to reveal brighter, smoother skin and reduce the visible appearance of dark spots and fine lines.

This targeted treatment from Sunday Riley combines high‑potency, purified lactic acid with brightening botanicals to lift away dullness and even skin tone. Lightweight and fast‑acting, the formula works on the skin’s surface to clarify texture and enhance radiance while supporting a more refined-looking complexion. It’s formulated without common irritants and layered with soothing and conditioning extracts to help maintain comfort during exfoliation.

How quickly will I notice smoother, brighter skin?

Good Genes is designed for visible surface results right away and progressive improvements over time. Within minutes you can expect a more plumped, radiant look; continued nightly or regular use targets discoloration and texture for cumulative benefits.

• Fast-acting lactic acid exfoliates dead skin cell buildup for immediate clarity.
• Contains licorice extract to support a brighter, more even tone over weeks.
• Formulation includes soothing aloe and botanicals to temper irritation.

What makes this serum different from other exfoliants?

Unlike harsh physical scrubs, this product relies on purified lactic acid — an AHA known for gentle, chemical exfoliation — paired with botanical brighteners and moisturizers. The result is a multi‑tasking treatment that refines texture while also addressing visible dark spots and signs of aging without over‑stripping the skin.

• High‑potency, purified lactic acid for controlled surface exfoliation.
• Licorice and lemongrass help support radiance and evenness.
• Squalane, aloe, and plant extracts help maintain hydration and soothe.

How should I incorporate Good Genes into my skincare routine?

Use as a treatment step after cleansing and before heavier creams or oils. Begin with a few nights a week if you are new to AHAs, then adjust frequency based on tolerance and results. Always follow with daytime SPF when using exfoliating acids.

• Apply a thin layer to clean, dry skin; allow it to absorb before moisturizing.
• Start slowly (every other night) and increase as tolerated for steady improvement.
• Use daily sunscreen during daytime to protect newly revealed skin cells.

Is this product suitable for sensitive or reactive skin types?

The formula includes soothing components like aloe and balancing botanicals, and it is free from fragrances, parabens, sulfates, and many common irritants. However, because it contains a potent AHA, patch testing and gradual introduction are recommended for sensitive skin to gauge tolerance.

• Fragrance-free and formulated without many common allergens.
• Aloe and botanical extracts help calm the skin during exfoliation.
• Patch test and introduce slowly if you have reactive or very sensitive skin.

Who is this for: Good Genes is ideal for anyone looking to refine texture, fade the appearance of dark spots, and lift overall radiance—especially those experiencing dullness, uneven tone, or the first visible signs of aging. It suits users who prefer a concentrated, leave-on lactic acid treatment that pairs with moisturizers and serums in a targeted skincare routine. If you are new to chemical exfoliants or have highly sensitive skin, start with reduced frequency and consult with a skincare professional as needed.
