Facial lipoatrophy is a decrease or loss of subcutaneous adipose tissue, affecting mainly facial regions. The progressive loss of facial fat, especially due to the decrease in malar fat (Bichat fat) and temporal fat, causes the appearance of skin ridges with wrinkling of the face, areas of depression and evidence of bone structure.¹
This loss of adipose tissue may be caused either by the natural aging process or by different systemic diseases such as discoid lupus, traumatic fat atrophies, or in response to the use of antiretroviral drugs for HIV treatment.
To correct the skin grooves and depressions produced by lipoatrophy it is recommended to perform facial filling with subdermal implants such as Calcium Hydroxyapatite (CaHa). Calcium Hydroxyapatite is a naturally occurring mineral found in bones and teeth which makes it a safe and biocompatible material even when synthetically obtained.
In addition to its volumizing characteristics, Calcium Hydroxyapatite is also used to biostimulate collagen production to improve skin appearance.
