La Roche-Posay is a French manufacturer that makes the best sunscreen in my opinion. I bought this product on eBay a couple months ago and it goes everywhere with me.  I have very fair skin and also live in California, so I am always on the lookout for products with SPF and that will protect me from the damaging effects of the sun. 

La Roche-Posay Anthelios makes the best sunscreen out there in my opinion.  I use the SPF 60+.  It is the most lightweight, non-greasy, and not heavily fragranced, so I can wear it every day and not feel like I have a mask on, and most importantly, it is the most effective sunscreen.  It really works!! I can tell because after I put it on my face, I use the residual and wipe it on the back of my hands.  My skin on the back of my hands is now a few shades lighter than the rest of my arm. 

Dr's claim that one of the most effective anti-aging products out there is to wear sunscreen or a product with SPF ever day, and not expensive lotions and creams.  I highly suggest trying this sunscreen for every day use.
