Sunday Riley Good Genes Lactic Acid Treatment Face Serum 0.5 oz — Brightening, Exfoliating

Sunday Riley Good Genes is a concentrated lactic acid facial serum designed to gently exfoliate surface dead skin cells to reveal smoother, brighter-looking skin and a plumped appearance in minutes.

Good Genes is a lactic acid–based treatment serum from Sunday Riley that targets dullness, uneven texture, and the look of fine lines. Its lightweight formulation helps lift away dead surface cells to improve clarity and radiance while smoothing skin’s appearance. The formula is used as part of a skincare routine to support a refreshed-looking complexion and is suitable for targeted nightly or occasional daytime use with sunscreen.

How quickly will I see a difference after using Good Genes?

Many users notice a visible change to skin texture and radiance shortly after application, with more marked improvements over continued use. Initial plumping and brightening effects can appear within minutes for some complexions, while ongoing exfoliation refines tone and smoothness over weeks.

• Immediate: perceived smoothing and brighter surface glow within minutes for many users
• Short term: improved texture and reduced look of dullness after several applications
• Longer term: continued exfoliation promotes even tone and smoother appearance

How should I incorporate Good Genes into my skincare routine?

Apply a few drops to clean, dry skin after cleansing and before heavier creams or oils. Start with less frequent use if you have sensitive skin, and always follow daytime use with a broad-spectrum sunscreen to protect newly revealed skin layers.

• Use: apply 2–3 drops to face, neck, and décolletage as needed
• Frequency: begin 2–3 times weekly, increase as tolerated
• Layering: apply before moisturizers and oils; allow to absorb fully
• Sun care: use daily SPF when using exfoliating acids

Is Good Genes suitable for my skin type and concerns?

Good Genes works for a range of skin types aiming to reduce the look of dullness, uneven texture, and fine lines. Those with very reactive or highly sensitized skin should patch-test and introduce the serum slowly to assess tolerance.

• Oily/combination: helps smooth texture and refine pores’ appearance
• Dry: can aid surface flaking when used with hydrating creams
• Sensitive: patch-test and reduce frequency to avoid irritation
• Concerned about discoloration: supports brighter-looking surface tone

What results can I expect and are there precautions?

Expect clearer-looking skin texture, enhanced radiance, and the appearance of smoother fine lines with regular use. Because it contains an active exfoliant, avoid mixing with other strong acids or retinoids without guidance and always protect skin from sun exposure after use.

• Results: smoother texture and brighter-looking skin surface over time
• Mixing actives: consult guidance before combining with other exfoliants
• Irritation: discontinue if severe redness or discomfort occurs
• Sun protection: apply SPF daily when using exfoliating treatments

Who is this for: Good Genes is aimed at people looking to visibly refine surface texture, boost radiance, and soften the look of fine lines. It fits into routines for those who want targeted exfoliation without heavy peeling, and for anyone prepared to introduce an acid treatment carefully with appropriate sun protection and layering adjustments for sensitive skin.
