Oxidation in a blackhead primarily leads to which change?

Size reduction
Color darkening
Texture softening
Size enlargement

The correct answer is: Color darkening

The correct answer is color darkening. In the context of blackheads, which are a type of open comedo, oxidation plays a significant role in their appearance. When sebum, the oily substance produced by sebaceous glands, gets trapped in hair follicles alongside dead skin cells, it forms a blockage. When this blockage is exposed to air, the melanin in the sebum undergoes oxidation, leading to the characteristic black or dark coloration of blackheads. This is why individuals observe that the appearance of blackheads is often darker compared to the surrounding skin. Understanding this process helps estheticians identify and treat the various stages and types of acne, as knowing the factors that contribute to their formation allows for better prevention and treatment strategies.
