This summer I vow to never get a sunburn.
Which is basically an impossible task for someone like myself (WHITE AS ALL HELL.). I've never managed to get through a whole summer without some sort of burn -- ranging from some red, irritated skin to peeling shoulders to WHAT THE HELL HAPPENED AM I GOING TO NEED A SKIN TRANSPLANT. But, not this time. No, no. This is going to be the summer of shade and the summer of Clarins' UV Plus HP Day Screen High Protection.
This stuff is seriously stellar -- I've gone though 1/2 a bottle already and it is my go to facial sunscreen. I've become even more cognizant about sun protection than before (read: I'm becoming an SPF psychopath) because I'll be damned if I'm getting skin cancer again! With SPF 40 and UVA-UVB protection you can trust, not just some added SPF to your makeup product, this physical sunscreen (sing it with me: "I AM TITANNNIUMMM... dioxide") feels weightless on your skin and doesn't leave any awkward white cast. Note: I've not paid attention/tested this for flashback with photography, so I can't help you there.
Apply it under makeup. Wear it alone. Check out the tinted versions (too dark for me, otherwise I would). Whatever you do, just get it and wear it every day.
