Protection against both UVA and UVB is very important, therefore ...
متن کاملCorrelation Between Sun Protection Factor and Antioxidant Activity, Phenol and Flavonoid Contents of Some Medicinal Plants
Long exposure of UV radiation increases risk of skin diseases such as cancer and photoallergic reactions. UV-B (280-320 nm) radiation is mainly responsible for inducing skin problems. Skin protection is a suitable method in the fight against ultraviolet radiation induced damage. Various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they h...
متن کاملSun protection factor: meaning and controversies.
The Sun Protection Factor (SPF) is the most important data to quantify the effectiveness of a sunscreen, being universally accepted. The method is based on determining the minimum erythematous dose (MED), defined as the smallest amount of energy required for triggering the erythema, in areas of protected and unprotected skin. The SPF value is then calculated as the ratio between the MED of prot...
