Although it may seem counterintuitive, dry skin can result in pores getting more easily clogged, thereby worsening acne. This is caused by the skin’s natural response to increase sebum production from the sebaceous glands if the skin gets too dry. Sebum is the naturally occurring, waxy, oily substance in the skin, produced by the sebaceous glands that are located next to the hair follicles. Excess sebum leads to clogging of the pores and secondary formation of acne lesions. Therefore moisturising your skin is very important if you are prone to acne.
