Kiehl's Better Screen UV Serum SPF 50+, Invisible Facial Sunscreen with Collagen Peptide, UV Filters to Shield UVA & UVB, Helps Correct Visible Signs of Aging, Boosts Skin Radiance

For some reason I thought I ordered the moisturizer with spf but I didn’t so I just ordered this; https://a.co/d/08LxRp4j I picked that based on reviews. I just got approved for retin-a so I’ll work that in to my routine and now I need to find a vitamin c serum. Should I be using a heavier moisturizer at night when I start the retinol or that goes on solo? I also vape and I have an appointment with my primary doctor to get help stopping since I know the random chemicals in that are not helping me either 🥲 trying to work from the inside out and change my health habits over all so I can feel and look better. ❤️
