Why does excessive scrubbing of skin exacerbate acne symptoms?

A)Reduces melanocyte UV protection
B)Depletes collagen fiber networks
C)Stimulates sebum production and inflammation
D)Inhibits keratinocyte differentiation cycles

💡 Explanation

Scrubbing triggers a rebound effect where sebaceous glands increase sebum output, because the body interprets the removal as a deficiency. This excess sebum, rather than cleaning the skin, promotes inflammation and blockage in pores, therefore exacerbating acne rather than alleviating it.
