Acne is a fact of life for a huge cross-section of society. It affects up to 95% of adolescents and 40% of adults1. Many people experience post-acne marks (Post-inflammatory hyperpigmentation or PIH for short) long after the acute acne has vanished. After tackling blemishes, they are still stuck fighting their post-acne marks, which can persist for several years or even a decade2 with the sun aggravating the symptoms. About 1 in 2 people experience post-acne marks. Men and women are equally susceptible, and all skin types can get post-acne marks, although it is more prevalent in darker tones of skin3.
