What skin issue does hydroquinone primarily address?

1. Acne

2. Hyperpigmentation

3. Dullness

4. Rough texture

The correct answer is: Hyperpigmentation

Hydroquinone is primarily used to address hyperpigmentation, which includes conditions such as melasma, age spots, and other forms of skin discoloration. This topical agent works by inhibiting melanin production in the skin, effectively lightening dark areas and promoting a more even skin tone. Its primary function makes it a popular choice for those looking to reduce the appearance of uneven pigmentation caused by sun exposure, hormonal changes, or other factors. In contrast, options addressing acne would involve treatments with ingredients focused on oil control and antibacterial properties, while dullness typically relates to a lack of natural glow, often addressed through exfoliation or hydration products. Rough texture pertains to the skin's surface condition, which may be improved through chemical exfoliants or moisturizers, but these treatments do not specifically target pigmentation issues like hydroquinone does. Thus, the identification of hyperpigmentation as the focus of hydroquinone's action is key to understanding its utility in cosmetic dermatology.
