Whiteheads and blackheads are both types of acne lesions that occur when hair follicles become clogged with oil, dead skin cells, and other debris. The main difference between them lies in the state of the pore and the exposure to air.

- Whiteheads (Closed Comedones):
- Whiteheads are also known as closed comedones.
- The pore is clogged, but the top remains closed, preventing the contents from being exposed to air.
- The trapped material, which includes oil, dead skin cells, and bacteria, appears as a small, flesh-colored or white bump on the skin.
- Since the contents are not exposed to air, whiteheads do not oxidize and retain their light color.
- Blackheads (Open Comedones):
- Blackheads are also known as open comedones.
- The pore is clogged, and the top is open, allowing the contents to be exposed to air.
- The trapped material oxidizes when it comes into contact with air, turning it dark in color, usually black or brown.
- Blackheads appear as small, dark dots on the skin.
In summary, the key distinction is the exposure to air. If the pore is closed, it forms a whitehead, and if it’s open, it forms a blackhead. Both can be treated and managed through proper skincare practices, but some people may be more prone to one type over the other based on factors such as skin type and genetics.
