Are chemical sunscreens safe to use with Tretinoin?

Question

Hello. I'm male, 29 y. Fair Mediterranean skin type. My question: Is it safe to use chemical Sunscreens with Tretinoin? I read that Tretinoin thins out the outermost layer of the skin, the stratum corneum. I also read that chemical Sunscreens need an intact stratum corneum to work. Does using Tretinoin therefore render chemical Sunscreens ineffective or is it a safe combination? Thank you very much.

Combining Tretinoin and chemical sunscreens is generally considered safe. While Tretinoin can thin the outermost layer of the skin, it primarily affects the epidermis and works to promote skin renewal. Chemical sunscreens typically penetrate the skin and provide protection by absorbing UV radiation.

However, it's crucial to follow proper skincare guidelines. Ensure you apply Tretinoin at night and use sunscreen during the day to protect your skin from harmful UV rays.

Best of luck !
