According to a PR Newswire study report, by the end of 2026, 23 million people will be affected by acne in India. Acne is a skin condition caused when the sebaceous glands (release sebum) in the skin become clogged. This blockage of sebum causes the growth of a bacterium known as Propionibacterium acnes that leads to pimples, spots and cysts. Several factors can cause an obstruction in oil levels: stress, hormonal changes, genetics, oily diet and infections. Conventional treatment for acne is very expensive and can cause side effects such as redness, irritation, peeling skin and dry skin. Here are some natural ways to treat acne.
