By applying hyaluronic acid to the middle and deeper layers of the skin, cells are provided with a hydrated environment necessary for proper functioning and the production of new collagen and elastin. By delivering hyaluronic acid with a needle, fine surface wrinkles are removed and the skin tone is smoothed, while its presence in the intercellular connective tissue will ensure a rejuvenating effect for months after the treatment. Although they contain hyaluronic acid, it is less concentrated and has a much less viscous texture in them, which is why the result will not be a reshaping of the face or a change in volume, but rather a deep subcutaneous hydration that is impossible to achieve with any cream.
