Hyaluronic Acid helps the skin retain water, therefore giving the skin a plumper and firmer appearance through moisturisation. However as we age, the natural levels of Hyaluronic acid decrease, so adding this ingredient back into the skin can help prevent signs of ageing. Adding a collagen booster can help stimulate the production of the skin’s own collagen, strengthening the skin to produce a plumper look that appears fresh and youthful.
