Actinic keratosis? Give your skin a new chance Sun exposure may cause cellular DNA damage that builds up over the years. This is known as actinic damage. The effects can be mild, such as wrinkles or blemishes, or severe, such as raised blemishes, itching and flaking, known as actinic keratosis (AK) or non-melanoma skin cancer (NMSC). It is estimated that for every visible actinic keratosis, there are up to 10 subclinical lesions in the immediate area that are still not visible, forming what is known as cancerisation field. The skin will look normal, but the sun will have caused internal changes that will probably develop into new actinic keratoses. If you have been treated for actinic keratosis, it is very important to treat the entire subclinical cancerisation field to prevent new lesions in the area. Repairs DNA Photolyase The sun has an impact on cells and causes damage to DNA. Healthy people are only able to repair 45% of this damage naturally. Plankton is a microorganism that is permanently exposed to the sun. That is why its DNA contains photolyase, which provides fool-proof protection against the sun's harmful effects. Found in Eryfotona as DNA RepairsomesTM, photolyase locates and repairs a further 45% of solar damage that your body is not able to repair, thereby doubling your skin's restorative capacity.
