Sunday Riley Good Genes lactic acid face serum — 30ml brightening & smoothing treatment

Good Genes All-in-One Lactic Acid Treatment by Sunday Riley is a targeted lactic-acid face serum that exfoliates, brightens, and smooths skin for an immediate glow and improved texture.

This concentrated treatment uses purified, high-potency lactic acid to lift away dull surface cells, refine pores, and promote a more radiant, even-looking complexion. Enhanced with clarifying botanicals like licorice extract, the formula is presented as a multitasking step in your skincare routine that addresses rough texture, visible lines, and uneven tone with repeat use.

How does Good Genes produce faster radiance?

The serum relies on lactic acid, an alpha hydroxy acid (AHA), to accelerate surface exfoliation and reveal fresher skin beneath. This immediate removal of dead skin cells smooths texture and increases light reflection, so skin appears brighter right away while continued use improves clarity over weeks.

• Rapid surface exfoliation using purified, high-potency lactic acid for instant glow
• Licorice extract helps minimize the appearance of discoloration
• Formulated to refine visible pores and soften rough patches

Is Good Genes suitable for sensitive or all skin types?

Good Genes is marketed for all skin types and ages, but because it contains an active AHA, users with sensitive skin should introduce it gradually and watch for irritation. The formula is fragrance-free and combines botanicals intended to balance skin, which can help reduce irritation when used as directed.

• Fragrance-free and plant-enhanced to lower irritation potential
• Start with fewer applications per week if your skin is reactive
• Always follow with sun protection during daytime use

When will I see improvements in lines, texture, and dark spots?

Visible smoothing and plumping of fine lines can appear quickly as surface cells are cleared, while fading of dark spots and hyperpigmentation usually requires consistent use over several weeks. Results build over time as exfoliation promotes cell turnover and the brightening botanical supports even tone.

• Immediate textural smoothing after application
• Noticeable reduction in the appearance of fine lines with repeated use
• Dark spot improvement typically develops with ongoing treatment

How should I add Good Genes to my skincare routine?

Apply a thin layer to clean, dry skin—either morning or night—then follow with moisturizer. When used during the day, pair it with a broad-spectrum sunscreen to protect newly revealed skin. For sensitive skin, alternate nights or dilute with your serum or moisturizer until tolerance is established.

• Use on clean skin; apply a thin, even layer
• Follow with moisturizer and daytime SPF if applied in the morning
• Adjust frequency based on tolerance—start gradually

Who is this for: Good Genes suits anyone seeking a concentrated lactic-acid treatment to improve dullness, uneven texture, and the visible signs of aging. It’s appropriate for those who want a clinically oriented, fragrance-free formula backed by botanicals, and for users ready to introduce an AHA product into a measured routine with sun protection.
