Hi! 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.  1. Avoid breaking the boils  2. Use a good sunscreen properly  You can start with Clindamycin containing medicine like Erytop gel.
