IV.Accumulation or absence of fat under the skin
Fat can accumulate under the skin with or without creating folds
Example: fat excess in the neck, lower eyelid bags
Treatment: Alone or in combination with wrinkles or folds, the best treatment is a liposuction or laser lipo or direct resection of fat
Fat can disappear with aging, giving the area a hollow aspect.
Example: hollow cheeks and eyes
Treatment: fat grafting, a technique, which is fashionable again. Invented 100 years ago, it was used with variable results until standards have been developed to improve the survival of fat grafts.
V. Volume deficiencies or excesses
Sometimes specific areas in the face are not full enough or too full
