There is no conclusive evidence that cocoa butter is effective at reducing the appearance of acne scars. Keeping the scar protected from the sun through the usage of sunscreen is one of the most important steps an individual can take to minimize the appearance of a scar.
Products that have been proven to make scars less noticeable are silicone sheets and bleaching creams. A silicone gel sheet is held against the scar on a daily basis for at least 3 months to make it less noticeable. Bleaching creams help make hyper-pigmented scars lighter. Severe scars are often treated with steroid injections, laser resurfacing and surgical removal.
