## Questions and answers

### What makes Sunday Riley Good Genes a great fit for combination skin?

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

Lactic acid helps balance combination skin by gently removing dead surface cells and managing oil while keeping moisture locked in.

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

This exfoliant treatment goes in your evening routine, applied after cleansing and before moisturizing. Start by using it once a week, and if your skin tolerates it well and shows good results, you can carefully use it more often.

### 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 help prevent irritation on your combination skin. If your skin is very used to both, apply this treatment first after cleansing, let it sink in, and follow with your retinol.

### How often should I use this exfoliant?

Start by using this exfoliant once a week in your evening routine, and if your skin feels comfortable and you see good results, you can carefully use it more often. This gentle approach helps your skin adjust to the active ingredients while minimizing the risk of irritation.
