• Abstract:

  Aging is a natural process that results in structural changes in the skin, such as wrinkles, sagging, and loss of elasticity, mainly caused by a decrease in collagen and elastin. These signs, associated with beauty standards imposed by society and social media, increase the demand for cosmetic procedures, with Brazil being the second country that performs the most such interventions. The skin is formed by the epidermis, dermis, and hypodermis, which undergo changes with intrinsic aging (genetic and hormonal factors) and extrinsic aging (solar radiation, smoking, alcoholism). These changes compromise facial support due to fiber degradation, reduction of deep fat, and bone resorption.  Calcium hydroxyapatite (CaHA) stands out as a biocompatible, biodegradable biomaterial that is absorbable by the body. Its action is characterized by an immediate filling effect, followed by biostimulation of fibroblasts, which promote the synthesis of type I and III collagen, elastin, and angiogenesis. This dual function ensures long-lasting functional and aesthetic results, improving skin firmness, elasticity, and quality. Studies show that CaHA is more effective in collagen production compared to other fillers, such as hyaluronic acid, and has advantages over poly-L-lactic acid because it combines volumization and biostimulation. Thus, it is one of the most strategic therapeutic options for facial rejuvenation, contouring, and tissue support.
