I had Mohs surgery on my chin about 3 weeks ago, the steri strips are just beginning to come off. I was advised to apply sunscreen when the wound was "completely healed," and I'm not sure what the definition of that would be. The scar feels a bit sensitive. I would like to know what to do next --apply sunscreen, lotion, etc, but don't want to cause damage or irritation. Thanks!
My sunscreen is titanium dioxide/zinc oxide based and I often reapply it throughout the day on top of my makeup in order to maintain protection. Is this effective at blocking uva/uvb rays, unlike doing so with chemical sunscreens (which to my understanding need to be applied directly to dry clean skin in order to work)?
