What to expect as you age: 25 or under

At this age, the skin should look plump and youthful, your skin tone should be even and bright, and lines and wrinkles should be virtually non-existent- unless you have a very expressive face, in which case they might faintly appear around your smile lines, between the brows or across your forehead. One change you might notice is that your pores get a little larger, which is one of the first signs of lowering collagen levels.
