Acne, the sign of a changing human

Acne is not restricted to adolescents going through their teen years. Nope, acne shows up during times of  major hormonal changes. There is "baby acne" when a baby is just adjusting to its new world and growth hormones are just kicking in. Of course puberty is the next stage of life when acne shows its ugly blackhead. Then as if we have not had enough of acne already, adult acne shows up in our 20's and 30's. That late stage acne could be due to other hormonal influences induced by stress or premature aging.
