Use as often as you'd like, and at least twice per day. In the morning, apply it before your sunscreen. Let it sink into your skin first - it might take 1-5 minutes because of the rich texture of this product.

Use your azelaic acid product every other day, either in the morning before your sunscreen or at night, before your moisturizer.

Use a generous amount of product to remove all dirt, sunscreen or makeup in one step. There is no need to double-cleanse. It is a good idea to always finish cleansing with a splash of clean water to remove any residue from the cleanser. Most people only need to cleanse their skin with a cleanser once per day, at night. It is the first step of a night skincare routine.

Use this product up to two times per week, either day or night, on clean skin. Follow up with your moisturizer or sunscreen.
