Fine lines are small, shallow wrinkles or creases that typically develop on the skin as a natural part of the aging process. They are often the earliest signs of aging and commonly appear on areas of the face that are prone to repetitive movements or sun exposure. Fine lines can vary in depth, length, and location, and they may become more noticeable over time.
Fine lines are usually small and thin, measuring only a few millimeters in length. They are typically narrower and less noticeable than deeper wrinkles and may not be visible from a distance. Fine lines commonly appear in areas of the face that are subject to repeated facial expressions or muscle movements, such as the forehead, around the eyes (crow’s feet), between the eyebrows (frown lines), and around the mouth (smile lines or nasolabial folds).
