Dealing with spots
To squeeze or not to squeeze...
Hormones
Spots (also known as acne) are the skin's response to the hormone testosterone, which can over-stimulate a natural oil called sebum. This gets secreted onto the surface of the skin through tiny open pores. If a blockage occurs a blackhead forms, trapping oil that can breed bacteria. The area becomes inflamed and the zit makes an appearance.
Nearly 70% of people get acne and many are affected in their 20s and 30s.
