retinal. Lately I am very happy with the results I have been seeing from Dr. Whitney Bowe Beauty’s Retinal Night. This .1% Retinal serum is gentle yet effective. I do not have sensitive skin and am used to using Retinal, so I jumped right in. I used it five days on two days off for a month with no issues. I had zero peeling or signs of sensitivity. I like how the consistency goes on and seems to absorb fast. It layered well under my night-time moisturizer. I think this a great option if you are looking for Retinal.
