You should only be using retinol at night! It’s most effective then since it helps with the turnover of your skin (top layer) in turn helping with scaring, wrinkles, and acne. Since your skin doesn’t have that top most worn layer it’s more susceptible to burning, dark spots, etc. But as long as you reapply spf throughout the day and wear a hat you should be fine.
Yes I was planning on doing it at night as the packaging stated that thank you for saying that though bc that wouldn’t be good if I used it in the morning. So if I use it at night and say 10-12 hours later it’s the day and I have to go out will I be okay just wearing sunscreen and shading as I can?
