Tyrosinase inhibitors like Hydroquinone are used for which of the following?

Tyrosinase inhibitors, such as Hydroquinone, are effective in treating various skin conditions associated with excess melanin production. Hydroquinone works by inhibiting an enzyme called tyrosinase, which plays a crucial role in the synthesis of melanin. This property makes it beneficial for a range of pigmentation issues.

For darker skin types, Hydroquinone can help manage hyperpigmentation, which is often more pronounced and can occur due to increased melanin. Melasma, a common condition characterized by brown patches on the skin, particularly on the face, can also be effectively treated with hydroquinone, as it helps to reduce the appearance of these dark patches. Similarly, post-inflammatory hyperpigmentation (PIH), which can result from inflammation or injury to the skin, is addressed by hydroquinone by lightening the affected areas.

Since Hydroquinone can be used for all of these conditions, the selection that includes all of the indicated uses correctly identifies its broad applicability in treating various pigmentation disorders.
