Full Review

Sunday Riley Good Genes Lactic Acid Treatment is a potent, multitasking skincare product designed to exfoliate, brighten, and smooth the skin. Formulated with purified lactic acid derived from fermented sugar, this treatment gently removes dead skin cells to reveal a more radiant and even complexion. It also helps reduce the appearance of fine lines, wrinkles, and dark spots by promoting skin cell turnover and rejuvenation. The formula is lightweight and suitable for all skin types, including sensitive skin, making it a versatile addition to any skincare routine.

Beyond exfoliation, Good Genes contains licorice root extract to brighten dullness and reduce pigmentation, while lemongrass provides antioxidant benefits and a fresh scent. The treatment works both as a daily serum or an intensive weekly treatment, offering flexibility based on your skin’s needs. With consistent use, users report softer, smoother skin texture and a more youthful glow.

The product is free from parabens and sulfates, aligning with clean beauty standards. Packaged in an air-tight, opaque bottle, it ensures product stability and potency over time. While the price point leans toward the premium side, the visible results and high-quality ingredients justify the investment for many skincare enthusiasts.

Radiant skin in weeks
I noticed a significant improvement in my skin’s glow and smoothness after just a few uses. It’s gentle enough for my sensitive skin and doesn’t cause redness. Highly recommend!

Effective but pricey
This treatment really helped reduce my dark spots and evened out my skin tone. The only downside is the cost, but the results justify it for me.

Great for sensitive skin
I was worried about using acids on my sensitive skin but this product was surprisingly gentle. I experienced only a mild tingling at first, and my skin improved visibly.
