What term describes the tendency of a substance to worsen dead cell buildup leading to comedones?

1. Non-comedogenicity

2. Comedogenicity

3. Hypoallergenic

4. Occlusiveness

The correct answer is: Comedogenicity

Comedogenicity refers to the tendency of a substance to cause or exacerbate the formation of comedones, which are the clogged pores that can lead to acne. When a product has comedogenic properties, it means it may contribute to dead skin cell buildup and block the pores, resulting in blackheads and whiteheads. This property is crucial for estheticians to understand, as using products that are non-comedogenic is essential for clients who are prone to acne or have oily skin. The other terms, while relevant in the context of skin care, do not specifically address the issue of exacerbating dead cell buildup and comedone formation. Non-comedogenicity indicates that a product does not clog pores; hypoallergenic refers to the likelihood of causing allergic reactions; and occlusiveness pertains to how a product forms a barrier on the skin, which can also lead to various skin issues, but not specifically to comedone formation. Therefore, understanding comedogenicity is vital for recommending suitable skincare products, especially for clients concerned with acne.
