I'll soon get my first VBeam treatment since 2 years to treat redness and vessels caused by Rosacea. I got told by my new doctor to wear 4-6 weeks before and 6 weeks after the treatment sun protection (50+) on the area to be treated (nose & cheeks). My old doctor though told me to wear sun prot. in the whole face,not just the treated area. As I wear a full beard it's annoying as I probab. would have to shave;also covering the whole face might irritate my skin. What's usually recommended? Thanks!
