Sunday Riley Good Genes Lactic Acid Serum 0.5 oz — Brightening, Exfoliating Treatment for Smoother Skin

Sunday Riley Good Genes is a concentrated lactic acid serum that instantly exfoliates surface dullness to reveal brighter, smoother, and visibly plumper-looking skin in minutes.

Formulated around purified lactic acid, this concentrated treatment works to lift away dead surface cells and improve skin clarity and texture. In a single 0.5 oz bottle, the serum targets dullness, uneven tone, and the look of fine lines without heavy residue, delivering an immediate glow and a refined finish suitable for morning or evening routines.

How quickly will I see results with Good Genes?

Many users report an immediate change in radiance and the appearance of smoother skin within minutes of application. Longer-term, regular use helps maintain clarity and a more even-looking complexion by promoting continuous surface exfoliation.

• Visible boost in glow and plumpness often within three minutes after application
• Consistent use supports reduction in the appearance of dark spots and discoloration
• Fast-absorbing, non-greasy texture for immediate makeup or SPF layering

What does this serum do for texture and tone?

The product addresses roughness by loosening and removing dull, dead surface cells so fresher skin emerges. That exfoliating action refines skin texture and helps fade the look of uneven pigmentation, contributing to a more uniform complexion over time.

• Lactic acid gently exfoliates to smooth bumpy or flaky areas
• Regular application helps brighten dark spots and reduce discoloration visibility
• Works under moisturizers and makeup without pilling

How should I incorporate Good Genes into my skincare routine?

Apply a thin layer to clean, dry skin before moisturizer and sunscreen in the morning or as part of your evening regimen. Because it contains lactic acid, introduce the treatment gradually if you’re new to chemical exfoliants and always follow with sunscreen during daytime use.

• Use after cleansing and before heavier creams or SPF
• Start with every other day, then increase frequency as tolerated
• Pair with sunscreen daily to protect newly revealed skin

Does Good Genes work for sensitive or aging skin?

The lactic acid formulation is often better tolerated than stronger acids because lactic acid both exfoliates and attracts moisture, which helps minimize dryness. Those with highly reactive skin should patch-test and consult a dermatologist if uncertain, then proceed slowly.

• Lactic acid offers gentle exfoliation with moisturizing properties
• Can help the look of fine lines by plumping the skin’s surface
• Patch-test recommended for reactive or very sensitive skin types

Who is this for? Sunday Riley Good Genes is designed for anyone seeking a targeted, high-performance lactic acid treatment to refresh lackluster skin, refine texture, and improve visible tone. It’s ideal for people looking for fast radiance and a smoother canvas under makeup, as well as those wanting a consistent exfoliating step that supports long-term clarity. If you’re new to chemical exfoliants, introduce it gradually and use daily sun protection to protect the renewed skin surface.
