Hi ! Thank you for your query. Pimples occur mainly due to hormonal imbalances which causes an overproduction of oil and cells inside a skin follicle. They block the opening of the skin pore and cause the follicle under the skin to swell and become red. It usually starts in teenage, but most of the time lasts into adulthood. Pimples can be comfortably controlled with treatment. There are many over the counter medications available in pharmacy but you need to use skin products which are most suitable to your skin. Avoid taking anti-acne medications without knowing a skin type. Treatment of acne includes medicines to reduce the breakouts, use of skin products such as face wash, cleansers, moisturisers according to your skin type and a whole range of aesthetic procedures like peels, laser therapy to reduce the current outbreaks and clean the skin, and clean clogged pores. They are safe and do not harm your skin in a long run.
