Skin booster injections are minimally invasive cosmetic treatments that deliver microinjections of hydrating substances, such as hyaluronic acid, deep into the skin to improve its tone, texture, and elasticity. They are designed to hydrate and plump the skin from within, reduce fine lines, and create a natural glow, without adding significant volume like a filler does. These injections can be used on the face, neck, décolletage, and hands.
