What negative effect can improper skincare application have on acne?

Improper skincare application can lead to product buildup and clogged pores, which is detrimental to individuals with acne-prone skin. When products are not applied correctly—whether too much product is used, layers are not allowed to absorb, or incompatible products are combined— residues can accumulate on the skin's surface. This accumulation can block hair follicles and lead to an increase in breakouts and inflammation. Effective skincare application is essential for allowing acne treatments to penetrate the skin properly and function as intended.

The other choices do not accurately describe the effects of improper skincare application. For instance, enhancing the effectiveness of treatments or promoting faster healing cannot occur without proper application and absorption of those products. Additionally, a moisturizing effect typically results from the right products being applied correctly, not from improper application. Therefore, understanding how skincare application impacts acne is critical for effective management and treatment strategies.
