Static lines in medicine refer to small wrinkles that can be visually observed on the face without any facial expression. They are obvious wrinkles. Static facial wrinkles can be divided into hyperkeratotic wrinkles and gravitational traction wrinkles, hyperkeratotic wrinkles appear early in the skin around the eyes, and become increasingly apparent after 30 years old. Gravity traction wrinkles are mainly due to aging caused by subcutaneous tissue atrophy, or because of long-term muscle contraction, the skin loses its elasticity, then wrinkles appear. Such as: Nasolabial fold, Marionette line and bilateral mandibular wrinkles. For people who often stay up late and those are often exposed to sunlight and computer radiation, wrinkles are inevitable. Hyawell Derm & Deep are your choice.
