Hand skin boosters are injectable treatments specifically formulated to improve the quality and appearance of dorsal hand skin. Unlike dermal fillers that add volume, skin boosters work by delivering hyaluronic acid, polynucleotides or other bio-stimulating ingredients directly into the dermal layer to enhance hydration, stimulate collagen production and improve skin texture, elasticity and tone. They're ideal for addressing crepiness, fine lines, dullness and age-related textural changes without altering hand structure.
