Dermal fillers use hyaluronic acid — a naturally occurring gel-like substance found in most tissues of the body. When injected into the skin, hyaluronic acid binds to water molecules to restore volume, improve hydration, and smooth out lines and wrinkles.
The natural ageing process involves a gradual reduction in hyaluronic acid content alongside the loss of subcutaneous fat — resulting in hollowness, lines, and a general softening of facial structure. Dermal fillers work by replacing what has been lost, restoring youthful facial proportions from within.
Restoring volume to the mid-face — particularly the cheeks — also has a lifting effect on the lower face, softening jowls and nasolabial and marionette lines without directly targeting them. This is the principle behind truly natural-looking filler treatment.
