Sunday Riley Good Genes Lactic Acid Serum 0.5 oz — Brightening, Texture-Smoothing Treatment

Sunday Riley Good Genes is an all-in-one lactic acid facial treatment serum that exfoliates dead surface cells to instantly brighten, smooth texture, and visibly plump the look of fine lines in minutes.

Formulated around purified lactic acid, this concentrated 0.5 oz serum targets dullness, uneven tone, and surface texture without heavy residue. The lightweight, single-step treatment works quickly to dissolve buildup on the skin’s surface, restoring clarity and enhancing natural radiance while improving the appearance of dark spots and fine lines.

How quickly will I see brighter, smoother skin with Good Genes?

Many users notice immediate improvements in luminosity and skin texture after the first application because lactic acid removes dead surface cells that trap dullness. Continued, regular use supports more even tone and a softer feel over weeks.

• Visible glow often within minutes after application
• Smoother skin texture with repeated use
• Helps reduce the look of surface discoloration over time

How should I add this lactic acid serum into my routine?

Use Good Genes once daily at night or as your routine allows, after cleansing and before moisturizers or oils. Start with a small amount to assess tolerance, then increase frequency if your skin adjusts comfortably.

• Apply to clean, dry skin — a little goes a long way
• Follow with a hydrating moisturizer or oil if needed
• Always pair daytime use with broad-spectrum SPF

Is Good Genes suitable for sensitive or reactive skin?

Lactic acid is a gentle alpha hydroxy acid compared with stronger exfoliants, but individual sensitivity varies. Patch testing and gradual introduction are recommended to minimize irritation while benefiting from exfoliation and brightening effects.

• Patch test on inner forearm before full-face use
• Begin with every-other-night application if concerned
• Discontinue use if persistent irritation occurs

What visible concerns does this treatment target?

Good Genes focuses on surface-level concerns: dullness, uneven texture, and the appearance of fine lines and dark spots. It’s designed to lift away dead skin cells and reveal fresher-looking skin without an overly aggressive approach.

• Instant radiance by removing dull surface cells
• Visibly plumps the look of fine lines and wrinkles
• Brightens the appearance of dark spots and discoloration

Who is this for: Sunday Riley Good Genes is aimed at anyone seeking a single-step exfoliating treatment to boost radiance and improve surface texture—suitable for those bothered by dullness, mild uneven tone, and the early look of fine lines. If you’re new to chemical exfoliation, introduce it gradually and protect skin from sun exposure when used during daytime routines.
