👉 Wrinkles are small lines or dots that appear on the surface of the skin. They can be caused by a variety of factors, including aging, genetics, and environmental factors such as pollution and sun exposure. Wrinkles can affect different parts of the face, but they usually occur in the creases between the eyebrows, under the eyes, and along the forehead. Wrinkles can also appear on specific areas of the face like the chin or neck.
