AestheFill® is a dermal filler composed of PDLLA (poly-D, L-lactic acid), designed to improve facial wrinkles and folds by stimulating collagen production. This filler fills the injected areas and maintains initial volume for an extended period. Clinical studies have confirmed its effectiveness and safety. Collagen, a vital scaffold protein, provides skin with smoothness and elasticity. However, as we age, collagen production decreases, leading to skin aging. AestheFill® helps restore collagen levels, addressing the aging process and enhancing skin appearance.
