What causes blemishes to develop in oily skin?

1. High levels of hydration

2. Clogged pores with oil and dead skin cells

3. Exposure to sunlight

4. Insufficient exfoliation

The correct answer is: Clogged pores with oil and dead skin cells

Blemishes in oily skin primarily develop due to clogged pores, which are often a result of excess oil production combined with dead skin cells. When the sebaceous glands produce too much sebum, this oily substance can mix with dead skin cells that normally shed from the skin’s surface. This combination can lead to blockages in the hair follicles or pores, creating an environment where bacteria can thrive. When bacteria multiply, it can lead to inflammation and the formation of blemishes like acne. While high hydration levels, exposure to sunlight, and insufficient exfoliation can influence skin health, they do not directly cause the primary issue of clogged pores in the context of oily skin. Proper exfoliation is crucial for helping to remove dead skin cells, but if the pores are already clogged due to oil, the blemishes will persist until the underlying issue is addressed. Therefore, the key factor leading to blemishes in oily skin is the accumulation of oil and dead skin cells that block the pores.
