Sunday Riley Good Genes Lactic Acid Serum 1.0 oz — Brightening Exfoliant for Smoother, Even-Toned Skin

Good Genes All‑In‑One Lactic Acid Treatment is a concentrated facial serum that gently dissolves dull surface skin to reveal smoother, brighter-looking complexion. This targeted formula from Sunday Riley uses purified, high‑potency lactic acid combined with botanicals like licorice and lemongrass to exfoliate, even tone, and restore clarity without heavy abrasion. The lightweight serum is designed for nightly or weekly use to refine texture, reduce the visible appearance of dark spots over time, and leave skin feeling softer and more radiant. It is formulated to be free from sulfates, parabens, gluten, soy, phthalates, and fragrances, and the brand is cruelty‑free and B Corp certified.

How does Good Genes refine skin texture so quickly?

Lactic acid is an AHA that works by loosening the bonds between dead surface cells so they slough away, revealing fresher skin beneath. Sunday Riley uses a purified, potent form to speed visible smoothing while supporting skin’s natural radiance.

• High‑potency lactic acid exfoliates surface buildup and congested pores.
• Lightweight serum consistency allows quick absorption and even coverage.
• Combined botanicals help comfort skin post‑exfoliation for less irritation.

Will Good Genes help with dark spots and uneven tone?

The formula pairs lactic acid’s exfoliation with licorice root and lemongrass extracts to gradually reduce the look of hyperpigmentation and sun‑related discoloration. Results depend on consistency; visible improvement in spot appearance is reported with continued use over weeks.

• Licorice extract supports reduction in visible pigmentation irregularities.
• Regular application helps fade the look of age spots and dark patches over time.
• Use alongside daily sunscreen to protect new, exposed skin and maintain results.

How quickly will I notice changes and how should I use it?

Many users notice immediate smoothing and a boost in radiance after the first application, while more pronounced changes to dark spots typically appear with consistent use over several weeks. Apply a few drops to clean, dry skin—start slowly if you’re new to acids, then increase frequency as tolerated.

• Apply to freshly cleansed, dry face—massage in gently until absorbed.
• Begin with 2–3 times per week at night, then increase as skin adapts.
• Always follow with sunscreen during daytime to protect newly revealed skin cells.

Is this serum suitable for sensitive or combination skin?

Good Genes blends soothing botanicals like aloe and cactus extracts alongside lactic acid to help mitigate irritation for many skin types. Sensitive skin users should patch test and introduce the serum gradually to assess tolerance.

• Aloe and botanical extracts help calm skin after exfoliation.
• Non‑greasy formula layers well under moisturizers and oils for combination skin.
• Patch testing is recommended for reactive or very sensitive skin types.

Who is this for: Good Genes is aimed at anyone seeking chemical exfoliation without physical scrubbing—those wanting to smooth fine lines, refine texture, and improve uneven tone. It works well for people with combination, normal, or drier skin who can tolerate AHAs, and for seasoned acid users looking to maintain clarity and brighten the complexion. If you have very reactive skin or advanced rosacea, consult a skincare professional before adding a high‑potency AHA serum to your routine.
