ISDIN Eryfotona AK-NMSC SPF100+ Fluid
Advanced daily photoprotection for actinic damage and sun-exposed skin
ISDIN Eryfotona AK-NMSC SPF100+ Fluid is a medical device formulated for the prevention and protective adjunctive treatment of actinic keratosis (AK) and other forms of non-melanoma skin cancer (NMSC). The formula combines very high broad-spectrum sun protection with DNA Repairsomes® technology to help protect the skin against further sun-induced damage while supporting the repair of actinic damage caused by chronic sun exposure.
Chronic exposure to UV radiation can progressively damage skin cells and contribute to the appearance of rough, scaly lesions known as actinic keratoses. These lesions commonly appear on areas frequently exposed to the sun, such as the face, forehead, ears, scalp, neckline, and back of the hands.
Thanks to its fluid texture, ISDIN Eryfotona AK-NMSC SPF100+ Fluid spreads easily across the skin and creates a protective film that helps absorb, reflect, and disperse UV radiation. Moreover, the lightweight formula blends comfortably into the skin without leaving a heavy finish.
This medical device has CE certification of conformity. Always read the instructions and leaflet carefully before use.
What is ISDIN Eryfotona AK-NMSC SPF100+ Fluid used for?
Long-term sun exposure can lead to cumulative cellular damage that may contribute to visible and subclinical actinic changes in the skin. Consequently, skin exposed to chronic UV radiation often requires daily high-level protection and ongoing care.
For this reason, ISDIN Eryfotona AK-NMSC SPF100+ Fluid helps:
- Prevent actinic damage caused by UV radiation
- Complement the protective treatment of actinic keratosis (AK)
- Support skin affected by non-melanoma skin cancer (NMSC)
- Reduce and improve the subclinical field of cancerization
- Create a protective film against solar radiation
- Provide very high UVA and UVB protection
Additionally, the formula supports daily protection for skin vulnerable to chronic sun exposure.

- Reinforce daily photoprotection in chronically sun-exposed skin
