Hi. If you get rashes on exposure to sunlight, it becomes a necessity to apply a sunscreen half hour before sun exposure and ideally every two hourly thereafter. You should also be taking oral antioxidants. Skinlite plays no role in the treatment of sun based allergy. As skinlite cream contains a steroid (along with two other components) it should b avoided. Even if ur using it for the pigmentation left behind, it should be used for not more then 3 weeks. Two years is a very long time hence it should be stopped. Please consult a dermatologist nearby.
