Hyaluronic acid (HA) is a naturally occurring substance that has a high concentration in the skin. It retains water and volumizes the skin in addition to adding viscoelasticity to the skin. As we age, HA concentrations decrease in addition to structural changes in the skin such as dermal thinning, fat loss and redistribution, laxity of facial ligaments, and bone loss. Soft tissue augmentation with HA fillers is a great way to create natural looking results that correct this aging process, leaving skin appearing smoother and brighter. It is safe, long lasting, about 8-12 months, and resorbable. Filler can be used to treat areas such as the midface, under eyes, temples, nasolabial folds, lips, chin, and jawline.
