White spots are one of the first signs of acne. First, a micro lesion (microcomedone) appears on the skin. This is invisible but it then turns into a blackhead or whitehead. An acne whitehead forms in the same way as a blackhead: it is a build-up of sebum and dead cells in a skin pore, except that in the case of a whitehead, a layer of cells covers the pore tip, hence the term "closed comedone" to describe the whitehead. The contents of the pore do not oxidize on contact with air and remain white, like a microbead under the skin.
White acne spots can break off and spread their contents to the outside or inside of the skin. White acne spots can also progress to an inflammatory stage, forming a red and painful acne spot.
To eliminate white acne spots and fight more generally against retentional lesions (blackheads and whiteheads), use cosmetics (lotions, creams, masks) that are filled with keratolytic-active ingredients to help unclog pores blocked by sebum and dead cells.
Unlike blackheads, whiteheads do not pierce easily. Don’t force them. Doing so can actually infect white acne spots and leave scars. Conversely, the prescribed treatment and daily care help to eliminate whiteheads from the skin. The dermatologist may also suggest removing white acne spots by skin cleansing or using laser treatment methods.
