I was never a frequent user of sunscreen and never cared about the type or SPF either. But it changed last year after I had a breast surgery. One has to be very careful about breasts after the surgery, so on the insistence of my doctor I started using sunscreen frequently. I realised that frequent use of sunscreen does create a lot of difference to you skin and now it is one of the most important thing in my vanity kit. I use L'Oreal Ombrelle, it’s what my friend recommended to me and I never bothered to change it or try out anything else.
