What is sun solar allergy?

Sun allergy (or polymorphic light eruption) is a condition that manifests with skin inflammation, itchiness and rash as a result of an exposure to UV rays. It appears in people who are extremely sensitive to sunlight and can begin immediately after the exposure, after a few minutes, a few hours or several days. How long it lasts also depends.

Once it begins, it is considered a chronic condition because it normally returns each spring (with the first exposure to the sun) and gradually diminishes over the summer.

A significant reduction in symptoms in 3 out of 4 users In users with prior sun allergy, Solar Allergy has proved to reduce the 75% of all allergy symptoms and, specifically, 95% of itching.

By starting this treatment 15-30 days before the first direct exposure to the sun and continuing throughout the exposure period, skin is protected. Its 1% of ectoine strengthens the skin’s natural protective mechanism and makes it more resistant to the sun’s radiation.

Combined with SPF 100+, it is the strongest sun care option for photosensitive skin. Its protection is 2 times higher than the minimum UVA protection (which cause sun allergy) required for a SPF 50+ sunscreen. Its effectiveness has been dermatologically proven.
