Apoptosis, also called cell death, is a complex and important process within our bodies. It results in specific cells being targeted, completely engulfed and eliminated. Although ‘cell death’ doesn’t sound like a positive process in the body, apoptosis performs important functions in fetal development, as well as keeping the skin free from mutated cells that can potentially lead to cancers.
During fetal development, the cells between the fingers and toes are targeted for apoptosis. If this process were not to occur, we would have webbed hands and feet. As it relates to skin cancer prevention, apoptosis contributes to the ridding of damaged cells from the skin. First, cells that are injured by UV exposure and other environmental offenders are identified. Then, cells called killer T cells communicate with the damaged cell and move to engulf it. The process continues with other biomolecules and proteins being summoned to participate in the breakdown and elimination of the mutated cell. Without this process, cells whose DNA has been damaged by UV radiation would be allowed to reproduce, resulting in the development of tumors.
An exciting ingredient that helps facilitate the process of targeting skin cells that have been damaged by UV exposure and instigating the process of apoptosis is caffeine. This powerhouse ingredient not only increases the antioxidant capabilities of other polyphenols, but also helps prevent cells with compromised DNA from reproducing and potentially causing skin cancer tumors. You can find topical caffeine along with the powerful antioxidant silybin in the whole range of PCA SKIN sun protection products including: Weightless Protection Broad Spectrum SPF 45, Perfecting Protection Broad Spectrum SPF 30, Protecting Hydrator Broad Spectrum SPF 30, Hydrator Plus Broad Spectrum SPF 30 and Active Broad Spectrum SPF 45.
