Questions about DUO-A 0.3%

What is in DUO-A 0.3%?

COSMEDIX builds it around 0.25% retinol and 0.05% retinal, with sodium hyaluronate and aloe vera.

How do I use it?

Every night, put one pump on clean, dry skin, staying away from the eye area, then follow with moisturizer. If you are new to retinoids, COSMEDIX says to ease in over the first two weeks and skip a night if your skin feels sensitive. Always wear sunscreen during the day. If you are pregnant or nursing, check with your doctor first.
