([International Journal of Molecular Sciences, 2019](https://pubmed.ncbi.nlm.nih.gov/31861912/))

This treatment goes in your evening routine, applied after cleansing and before your moisturizer. Putting it in the evening is simple and safe since certain active ingredients are better kept away from daytime sun exposure.

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

You can use this treatment with retinol by applying your retinol product first and following with this treatment, or by using retinol on alternate nights to prevent dryness or irritation. The soothing components and lack of harsh ingredients in this formula help keep your skin calm when combining active products.

### How often should I use this treatment?
