Blackheads can usually disappear on their own if they are not squeezed. Blackheads are a type of acne vulgaris, which is mainly due to the fact that the contents of the pimples are exposed to oxygen and dust in the air during the process of excretion, which results in a black appearance due to surface oxidation. In this case, it is actually a form of acne vulgaris. Generally, topical application of keratin softeners can be used to promote the outward excretion of the internal contents of blackheads, thus forming the automatic fading of blackheads.
