Acne scars form when the layers of skin under the epidermis become damaged due to a large blemish, whitehead, blackhead or other acne-related lesion. When the skin becomes damaged, excess collagen fibers can form, which can cause an irregular pattern–resulting in a scar. Many commercial creams currently utilize onion extract due to its effect on inflammation. In order to reduce the visibility of these scars, an acne treatment cream containing onion extract may be of benefit.
When applied regularly to an acne scar, onion extract can reduce inflammation in the skin, according to Go Ask Alice. This not only reduces redness that can accompany a newly forming scar, it also can reduce the scar’s size. A study conducted on the effectiveness of onion extract conducted by M. Hosnuter, et. al.,published in the June 2007 issue of the “Journal of Wound Care”, found that onion extract applied daily to a scar helped to reduce inflammation and discoloration. This is especially beneficial for treating acne scars, which tend to be on the face and are more noticeable when the scarred area is inflamed.
