## What reviewers say

Based on a very large amount of data, this lactic acid treatment is highly praised for its ability to quickly exfoliate and retexturize skin, resulting in a noticeable glow and smoother skin texture. Users with dullness, hyperpigmentation, and fine lines report significant improvements in skin clarity and plumpness. Many find it gentle enough for sensitive or acne-prone skin, though the high price point is a frequent concern.

## How to apply

- Use this exfoliant as part of your PM routine once a week, increasing slowly to twice a week if your dry skin tolerates it well. Always remember to apply SPF every morning to protect your newly smoothed skin.
- Apply the exfoliant after cleansing and toning, but always before your rich moisturizer.
- Gently press 2-3 drops of the exfoliant into your skin and let it absorb for a minute. Avoid rubbing to prevent any irritation on flaky areas.
- Apply the product directly to dry clean skin to ensure the best possible tolerance for your dry type. This helps address flaky patches without causing extra stress.
- Avoid the sensitive eye area and do a quick patch test before your very first use. Do not mix this with other strong acids or retinoids on the same night.

Sunday Riley Good Genes works moderately well for dry skin, helping smooth texture while supporting hydration. To fit dry skin better, a product of this type needs soothing and deeply hydrating ingredients like niacinamide, ceramides, and peptides.
Sources: [Molecules, 2025](https://pubmed.ncbi.nlm.nih.gov/40363772/)

### Which ingredients make this exfoliant a good fit for dry skin?

Lactic acid helps smooth dry skin texture, while squalane supports hydration and barrier function. To fit dry skin even better, an exfoliant treatment needs deeply soothing and hydrating ingredients like niacinamide, ceramides, peptides, and vitamin C.
Sources: [Molecules, 2025](https://pubmed.ncbi.nlm.nih.gov/40363772/)

### What does Lactic Acid do for dry skin?

Lactic acid helps relieve dry skin by drawing in moisture and strengthening the skin's barrier so it stays soft and smooth. This ingredient gently sheds dead cells and supports natural moisturizing factors, making it very useful for improving rough or flaky areas.
Sources: [International Journal of Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40231699/), [Skin Research and Technology, 2013](https://pubmed.ncbi.nlm.nih.gov/23521561/)

### What does Licorice Root Extract do for dry skin?

Licorice root extract helps calm dry skin by reducing redness and irritation, and it supports skin comfort. It is often combined with soothing ingredients and moisturizers to ease tightness and restore a smooth feel.
Sources: [Skin Pharmacology and Physiology, 2013](https://pubmed.ncbi.nlm.nih.gov/23549137/), [Pigment Cell Research, 1998](https://pubmed.ncbi.nlm.nih.gov/9870547/)

### Where does this exfoliant go in a skincare routine for dry skin?

This exfoliant goes in your evening routine, starting once a week before your moisturizer so your skin can adjust safely. An exfoliant for dry skin needs nourishing oils and soothing hydrators like ceramides, hyaluronic acid, or squalane to keep the skin barrier soft and smooth.

### Can I use this exfoliant with retinol, and in what order?

It is best to use this exfoliant on a different night than your retinol to avoid irritation on your dry skin. Alternating nights allows both active ingredients to smooth your texture safely without overwhelming your skin barrier.

### How often should I use this exfoliant?

Start using this exfoliant once a week in the evening, and if your skin feels good and shows nice results, you may carefully use it more often. A product of this type for dry skin needs extra hydrating and soothing ingredients, along with gentle exfoliants to smooth texture without causing dryness.

### Can this exfoliant clog pores, cause breakouts or purging for dry skin?

This exfoliant is unlikely to clog pores or cause breakouts for dry skin, and it is safe with no harsh ingredients that typically cause irritation. It helps smooth texture while supporting hydration.

### Is this exfoliant fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol. Cetearyl alcohol is a fatty alcohol, which soften the skin.
