Sunblock (also commonly known as sun screen, sun tan lotion, sun cream or block out) is a lotion, spray, gel or other topical product that absorbs or reflects some of the sun's ultraviolet (UV) radiation on the skin exposed to sunlight and thus helps protect against sunburn. Skin lightening products have sunscreen to protect lightened skin because light skin is more susceptible to sun damage than darker skin, a number of sunscreens have tanning power to help the skin to darken or tan.
The first effective sunscreen may have been developed by chemist Franz Greiter in 1938. The product, called Gletscher Crème(Glacier Cream), subsequently became the basis for the company Piz Buin (named in honor of the place Greiter allegedly obtained the sunburn that inspired his concoction), which is still today a marketer of sunscreen products. It has been estimated that Gletscher Crème had a sun protection factor of 2.

To calculate the Sun Protection Factor (SPF) for sunscreen products, you divide the amount of time it takes for skin to burn without sunscreen by the amount of time it takes with sunscreen. For example, if it takes 10 minutes to burn without sunscreen and 150 minutes with sunscreen, the SPF would be 150/10 15.
A lot of sunscreen
Yes, the sunscreen I am using is FDA approved.
Sunscreen is most effective when applied directly to clean, dry skin before any makeup, including foundation. If you apply foundation on top of sunscreen, it can reduce the sunscreen's effectiveness, particularly if the foundation is heavy or if it's applied in a way that disturbs the sunscreen layer. For best protection, consider using a makeup product that includes SPF or reapply sunscreen over makeup with a setting spray or powder sunscreen designed for that purpose.
Assuming the question is asking about sunscreen SPF, it stands for sun protection factor. This is put on sunscreen bottles to show the consumer how strong the sunscreen is.
Clinique foundation actually can contain or not contain sunscreen based on your preference. The options that do contain sunscreen contain 15 and up spf.
