Sunday Riley Good Genes All-in-One Lactic Acid Treatment Face Serum is formulated with a high concentration of lactic acid, a gentle alpha hydroxy acid that works to exfoliate the uppermost layer of the skin. This treatment aims to improve skin texture, reduce the appearance of fine lines, and brighten the overall complexion. The serum also includes licorice root extract, which is known for its soothing properties, and lemon peel extract to help refine pores.

The lactic acid in this formula targets dullness and uneven tone by encouraging natural cell turnover without the harshness often associated with stronger acids. It is designed for various skin types, including those with dry or dehydrated skin, as lactic acid also provides mild humectant benefits to support surface hydration.

This product is intended for use as a leave-on treatment and can be incorporated into a nightly skincare routine. The lightweight, fast-absorbing texture allows it to layer easily under moisturizers or oils. Good Genes is often positioned as an all-in-one solution for those seeking a multi-functional serum that addresses exfoliation, clarity, and a more even skin tone simultaneously.

Consistent use may help minimize the look of pores and soften the skin’s surface. The formula is free of synthetic dyes and sulfates, focusing on active ingredients that work gradually. It is suitable for individuals who want a lactic acid-based treatment that balances efficacy with a moderate level of gentleness, making it an option for those new to chemical exfoliants or with sensitive skin types that tolerate lactic acid well. No immediate results should be expected, as individual skin response varies based on frequency of use and overall skincare context.
