Very high sun protection for skin that reacts to the sun
ISDIN FotoUltra 100 Solar Allergy Fusion Fluid is a very high protection facial sunscreen for sensitive skin that feels reactive in the sun. It offers broad UVB/UVA protection rated SPF50+ and PA++++, plus protection against blue light. Its formula contains 1% ectoin, a natural protective molecule that helps the skin cope with sun stress, together with niacinamide and vitamin E for antioxidant support. A soothing complex of pentylene glycol and 4-t-butylcyclohexanol gives quick comfort from warm and tingling sensations.
The texture
An ultra-light fusion fluid that spreads easily and absorbs quickly without a greasy or sticky finish. It sits well under make-up and suits daily use as well as holidays.
Who it suits
- Skin that feels uncomfortable in summer sun
- Sun-sensitive and reactive skin
- Fair skin that burns quickly
- Anyone wanting a light, non-greasy SPF50+ for the face
Worth knowing before you buy: It is a face fluid in a 50ml size, so for large areas of the body you will need a body sunscreen as well. Like any sunscreen, it only protects if you apply enough and reapply every two hours.
