Blackheads are one of the first signs of acne. Initially, a micro lesion (microcomedone) appears on the skin due to hyperseborrhea (accumulation of sebum, oily skin and dilated pores) and hyperkeratinization (build-up of cells and thickening of the skin). This microlesion is invisible to the naked eye and turns into a black or white spot. Blackheads consist of a build-up of debris in a pore of the skin and the formation of a spot that oxidizes on contact with air and turns black.
Blackheads can rupture and spread their content outwards, either spontaneously or when pressed with fingers or a blackhead remover. Blackheads can also progress to an inflammatory stage and form a red and painful acne spot. They can also become infected if handled too much.
To eliminate blackheads, use cosmetics (lotions, creams, masks) filled with keratolytic-active ingredients that will help to unclog pores blocked by sebum and dead cells.
It is very tempting to pierce blackheads, especially if they are persistent or painful. But remember to be careful! If you touch the skin, you may end up with an infected blackhead or worse, a scar. You are better off using the prescribed treatment and daily care. The dermatologist may suggest removing the blackheads by skin cleansing or using laser treatment techniques.
