Is it ok to start using retin-a during summer? and use spf50 during the day? how often to apply retin-a when starting? thanks

Avoid sun : Avoid sun exposure bet. 10-2. Wear sunblock and reapply at least every 2 hours maybe even more. You can start by keeping it on your skin overnight or as short as you can tolerate. If you're itchy or it feels like it burning, wash it off, skip next day. Do the same next time until you are able to tolerate it without a lot of side effects. So start every other day woke it up to daily
