For the prevention of actinic keratosis and non-melanoma skin cancer Actinic Control MD SPF 100 is a certified medical device for the prevention of actinic keratosis and non-melanoma skin cancer. Furthermore, it serves as an adjunctive treatment for actinic keratosis. UV-induced DNA damage to keratinocytes can cause actinic keratosis. Actinic keratosis is the most common pre-cancer on the skin, potentially progressing into non-melanoma skin cancer (squamous cell carcinoma) if left untreated. But the right sun protection can make all the difference. The high effectiveness of Actinic Control MD comes from its high SPF 100. The higher the SPF, the more UVB-rays are blocked out – which are a major cause of cell damage. The more UVB-rays are blocked out, the less cell damage the skin will accumulate during sun exposure. An SPF 100 for example blocks out about 99% of UVB-rays. Additionally, the high SPF 100 can also compensate for sunscreen under-application. As a light textured fluid, it is suitable for everyday use, making it pleasant to apply, and easy for you to stay protected while enjoying everyday outdoor activities.
