I live in Florida and have been using Thalgos SPF 50 for years. It is light-weight, not greasy and never clogs my pores. I play tennis everyday and even when I am sweating it provides me with the protection I need to get me thru my whole game. I also like that I can wear it under makeup and it never feels heavy or makes my makeup look too thick. It is even gentle enough for my 2 year old grandson to use when he comes over for a day at the beach!
