FAQ Frequently Asked Questions

Wrinkles and fine lines become more noticeable when the skin’s firmness and moisture levels decrease due to factors such as dryness, UV exposure, and aging. Since wrinkles can form in areas subject to repeated facial movements as well as in areas where the skin has sagged, there is no single cause. At YAYOI CLINIC, we examine the location and depth of your wrinkles, as well as your skin condition, and recommend treatments tailored to the underlying causes.

Fine lines are shallow, delicate wrinkles that appear around the eyes and mouth, while expression lines are wrinkles—such as those between the eyebrows, on the forehead, and at the corners of the eyes—that tend to become more noticeable when facial muscles move. On the YAYOI CLINIC website, deep wrinkles such as nasolabial folds are also introduced as a separate category. Even if they look similar, their causes differ, so we determine the type of wrinkle during a consultation before selecting a treatment.
