Of the injectables, they are the most focused on deep skin hydration. Unlike a topical moisturizer, the skinboosters are injected into the area to be treated through a very fine and small needle or through cannulas in a subdermal plane providing a significant build up of water in the skin. The injected product is hyaluronic acid in gel form associated with other active ingredients (vitamins, amino acids, coenzymes, nucleic acids). When talking about global skin rejuvenation, the target is always water, that is, hydration.
