Sponsor: Cosmetique Active International

View on ClinicalTrials.gov

Summary

Participants will be invited to take part in a research study as they have been diagnosed with multiple actinic keratosis lesions (AK). AK usually present as small, rough, dry, scaly and/or crusty patches or papules of the skin that can be skin-coloured pink, red, tan or a combinationof colours and are often easier to feel than see at their earlier stages. AK are commonly diagnosed in adults, particularly in patients aged 45 years and older and are considered to be pre-cancerous lesions. The research is aiming to investigate the protective effect of an investigational sunscreen known as Anthelios Fluide 100 KA+ UVMune 400, when used together with good sun protection habits (which include staying in the shade during the hours of 11 am and 3 pm, wearing sun-protective clothing, wearing a wide-brimmed hat) in participants with multiple Actinic keratoses's. Eligible participants will be randomly assigned into 1 of 2 groups - an intervention or control group The study main objective is to evaluate tested sunscreen prevention on actinic keratosis lesions.
