The No. 1* recommendation for non-melanoma skin cancer**
Eryfotona AK Fluid is a medical product for the prevention and supportive treatment of actinic keratoses and non-melanoma skin cancer (NMSC).
Eryfotona AK Fluid combines a very high sun protection SPF 50+ with the DNA repair enzyme (photolyase). This prevents sun damage as a result of sun exposure and supports the treatment of skin changes.
The special thing about Eryfotona AK is that unique Repairsomes form a protection on the skin that reduces the formation of new lesions.
With visible results after 3 months of treatment(2)
Regular use of Eryfotona AK Fluid supports the natural DNA repair mechanism. This reduces DNA skin damage caused by sun exposure by half, thus preventing the appearance of new lesions after photodynamic therapy.(4)
The enzyme photolyase contained in Eryfotona AK sunscreen repairs DNA(3)
Due to sun exposure, skin cells are attacked and DNA is damaged. Healthy people can repair 45% of this DNA skin damage naturally.
Eryfotona AK sunscreen for non-melanoma skin cancer** contains unique DNA Repairsomes, a technology patented by ISDIN that supports the body in repairing a further 45% of this DNA damage. This doubles the skin's ability to repair itself.
The texture of the sunscreen becomes more fluid when shaken and melts into the skin. The sunscreen with a very high sun protection factor of 50+ is quickly absorbed and leaves a pleasant feeling on the skin. Suitable for all skin types.

Application:
For non-melanoma skin cancer, apply the sunscreen generously twice a day, morning and midday, to the entire affected area and other vulnerable, sun-exposed areas (face, forehead, ears, dcollet, bald head and back of the hand) - the effect of the photolyase unfolds with visible light. For night care, we recommend using Eryfotona Night to regenerate the skin.
