When do fine lines begin to appear?

The first signs of fine lines generally begin to appear during a person's mid to late 20s. By the 40s, the skin begins to lose elasticity and deep lines begin to appear around the mouth and eyes.

During the 20s, the skin begins to experience the first signs of dryness. While this can cut down on the number of blemishes that occurred during the teen years, it is also the major cause of the fine lines that appear around the eyes. In the 30s, the collagen and elastin levels in the skin begin to break down, pores get larger, and some women report seeing broken capillaries on the apples of the cheeks.
