Use every day, as many times as needed. For most people, it's best to use a moisturizer twice per day. In the morning, apply it before your sunscreen (or skip the moisturizer in the morning if your sunscreen feels hydrating enough). In the evening, a moisturizer is usually the last step of a routine.

Use every day before going outside, even if it is not sunny. Sunscreen is the last step of your morning skincare routine. You can apply makeup on top of it.
