According to scientists from the University of Michigan, the signs of aging can be reversed. This is especially true for fine wrinkles, deeper creases and saggy areas around the mouth and neck. According to them, some anti-aging treatments are effective in repairing collagen. They arrived at this result after more than a decade of studies. The results are published in the May issue of Archives of Dermatology.

Highlights of the study findings
a. Studies were conducted by University of Michigan dermatologists to explain why skin treatments using topical retinoic acid, carbon dioxide laser resurfacing and injections of cross-linked hyaluronic acid were effective.
b. Researchers found that the breakdown of the dermis' firm, youthful structure is a very important factor in skin aging.
c. A 2007 study looked at Restylane, marketed as a dermal filler.
d. It was seen that injections of the product caused fibroblasts to stretch, promoting new collagen.
e. It also limited the breakdown of collagen.
f. In another 2007 study, the researchers tested lotions containing retinol.
g. It was seen that this product significantly reduced wrinkles and skin roughness in elderly skin by promoting new collagen.
h. Other studies showed why some laser treatments work and some less powerful ones do not.
i. Carbon dioxide laser resurfacing proved to be effective as it removes the aging dermis and stimulates the production of new, young collagen is produced.
j. These 3 treatments improve the skin's appearance and boost its ability to resist bruises and tears by stimulating new collagen growth.
