SPF protection requirements whilst using Retin A, and facial oil issue.

Retin A treatment
Thank you for your question. In my opinion, any sunscreen SPF of 40 or greater is effective in protecting the skin from sun damage. No the SPF factor doesn't need to change as the strength of Retin A increases. I highly recommend you consult with a board certified dermatologist regarding your skin and treatment options that best suit your needs. Take care and good luck.
