I use Sofina SPF 23 for daily use, and SPF50 for outdoor use. I've been using it for almost 10 years now and it's the best sunblock I've ever used! I tell you what, I've been to Africa for 3 months, playing golf and water sports and my face doesn't look tan at all (my body does because I sometimes forgot to put sunblock on). I'd recommend Sofina to everyone!
