To identify whether there is a relationship in between a abyss of facial wrinkles as well as a density of a retinacula cutis in a subcutaneous tissue of a skin.Wrinkle abyss was assessed with picture research upon a forehead as well as a lateral canthus of human cadavers. The density of a retinacula cutis was totalled in Azan-Mallory-stained skin sections obtained around a wrinkles.Gross Anatomy Section, Kagoshima University Graduate School of Medical as well as Dental Sciences.Fifty-five male as well as female cadavers (35-93 years old).The maximum abyss of each wrinkle was used to represent a wrinkle's degree. In a skin sections, a density of a retinacula cutis was totalled around a deepest point of each wrinkle in a 1-mm-wide area (the wrinkle-specific area) as well as a 10-mm-wide area that included a wrinkle (the wrinkle-inclusive area).In both a wrinkle-specific as well as wrinkle-inclusive areas, a retinacula cutis densities became lower in a forehead as well as in a lateral canthus areas. When a wrinkle was shallow, a density was lower in a wrinkle-specific area than in a wrinkle-inclusive area. With wrinkle progression, a density disproportion in between a wrinkle-specific as well as a wrinkle-inclusive areas gradually decreased until there was no apparent difference.Facial wrinkles seem to rise above sites of reduced lower retinacula cutis density. As a wrinkle develops, a density decreases in both a wrinkle-specific as well as a wrinkle-inclusive areas, whereas a density disproportion in between those areas vanishes.
