Clinique super city block sunscreen cream has SPF 40 ultra protection plus boosted level of antioxidants and is oil-free face protector. It promises that it will protect skin from damaging UVA/UVB rays, protects from environmental aggressors and ability to hold makeup in place, making it last longer.
Sunscreen should be applied every day to exposed skin, and not just if you are going to be in the sun. Even on a cloudy day, up to 80 percent of the sun's ultraviolet rays can pass through the clouds. Sunlight consists of two types of harmful rays; ultraviolet A (UVA) rays and ultraviolet B (UVB) rays. UVA rays are the aging rays and UVB rays are the burning rays. Sunscreen plays an intergal part in prevention of premature aging and skin cancer.
I bought this sunscreen couple of months ago for daily use. It has worked well like they have promised. I even use this as a base for my foundation and its not greasy at all. It is sheer and absorbs quickly. Also when i used this sunscreen as a base for my make up it hold my make up longer. I used L'oreal solar expertise sunscreen before but i didn't like it at all. After two days of application I had to bin that sunscreen. My face looked so greasy after application and also left white streak on my face. I thought L'oreal probably would have good sunscreen because of their brand but it has let me down. I will never use their sunscreen again in my life.
Sunscreen should be applied before 15 to 30 mins before going outdoors to get maximum protection. Ideally, sunscreen with SPF 30 or higher provides broad-spectrum coverage against both UVA and UVB light. So, when you are buying one always go for higher SPF. The higher SPF, the better protection for your skin!!
