Many factors contribute to skin changes as we age; such as genetics, sun exposure and lifestyle factors. The formation of wrinkles and sagging skin is due to a loss of volume in the underlying tissues. Hyaluronic Acid Dermal Fillers have been approved by Health Canada to help improve this lost volume. The effects of Hyaluronic Acid Dermal Fillers can last anywhere from 6 months to one year, sometimes more! Results vary from person to person.
