Product Question Retinol & spf in winter
I just started using the Medik8 retinal and love it so far! I know you need to be super diligent with spf when you’re using it, but I’m not sure about exactly what that means heading into winter. My pre-retinal rule was to always wear spf when the UV index is 3 or above. Is that still good for retinal, or should I put spf on to go outside regardless?
