Acne symptoms usually include blackheads, whiteheads and pimples which can occur in the previously mentioned areas, and besides being highly unaesthetic, they can also become very painful if infected and can also leave scars. In terms of acne causes, there is no singular cause for these skin lesions. Acne occurs when sebum mixes with dead cells and clogs the pores or follicular openings. In time, these accumulations grow, forming smaller or larger bumps.

The hair follicle’s wall may rupture because of this growth, permitting the bacteria and other irritating substances to penetrate deeper into the skin, causing inflammation and redness. If the oil reaches the surface of the skin, it’s a whitehead; if it accumulated melanin and oxidizes due to contact with air, it’s a blackhead.
