As we age, the concentrations of collagen elastin and hyaluronic acid in the skin decrease. This accounts for the thinner skin and loss of skin hydration that occurs in aged skin, which causes wrinkles and skin laxity.
Under this situation, HA fillers are used to correct deep wrinkles and loss of facial volume. HA fillers correct wrinkles and loss of facial volume by two mechanisms, one is that HA draws water molecules into these tissues, increasing tissue volume, skin turgor and lubricating tissue and the other is the stimulation of collagen formation by cross-linked HA and formation of elastin. HA fillers have been found to improve the structural integrity and the appearance of aging skin when injected under the skin.
HA fillers for skin boosters improve skin texture and appearance in the following ways:
(1) Skin hydration-by injecting HA fillers into the skin, the HA molecules can draw water molecules up to 200x its weight into the dermis, resulting in improved skin hydration, roughness and fine wrinkles. When injected into acne scars, skin boosters can also "lift" depressed acne scars.
(2) Stimulating the synthesis of collagen and elastin in the skin.
(3) Restore dermal scaffolding support in a more homogenous and diffused pattern (more than localized injections for wrinkles and volume correction).
