Aesthetic dermatology: What's new, what's true?

Aesthetic dermatology (AD) is a rapidly growing subspecialty of dermatology. The acceptance of AD in scientific community and the society is associated with its competence, efficiency, and seriousness. This review highlights some recent developments toward new tools, techniques, and understanding in the field of AD. Analyzing the specific needs of patients and assessing the effect by objective measurements is important for further progress. For long time ignored, white adipose tissue has gained increasing interest in biology and rejuvenation. Characterization of dermal and subcutaneous white adipose tissue has made progress. The interaction of hyaluronic acid and calcium hydroxyl apatite (CaHA) fillers with adipocytes could be responsible for clinical efficacy. New developments of oral collagen treatment and highly diluted CaHA to contour the body outside the face will be discussed. Submental contouring using purified desoxycholic acid is another new development.
