Doctors from the University of Michigan Medical School, US, have found that injecting dermal fillers containing non-animal stabilised hyaluronic acid into sun damaged skin stimulates the production of collagen, and may partially restore its natural structure.
According to an article from the Archives of Dermatology, patients averaging 74 years-old that received three injections of 0.7ml of stabilised hyaluronic acid experienced induced type 1collagen production in their sun damaged skin. These findings, said a project note, suggest that in addition to its cosmetic benefits, “hyaluronic acid may be beneficial in skin-wasting diseases that involve collagen deficiencies, such as those associated with HIV or steroid use”.
