What do Korean pharmacists recommend for sun protection & tone?
Read the SPF number together with how much you apply. Raising the SPF is the easy part; making a sunscreen you'll actually wear daily is the hard part. Application amount, reapplying, and pigmentation care — all on one page.
Mineral vs chemical is mostly a difference in feel. Reapplying means layering on top, not starting over. Wear it on cloudy days and by the window too.
