用途
作用方式
Topical hydroquinone produces reversible depigmentation of the skin by inhibiting the enzymatic oxidation of tyrosine to dopa and suppressing other melanocyte metabolic processes.
成人常用劑量（仿單摘要）
Hyperpigmented skin conditions (chloasma, melasma, freckles, senile lentigines): apply to affected areas topically twice daily, morning and before bedtime, or as directed by a physician; discontinue if no lightening after two months
懷孕與哺乳
- 懷孕
- Unknown Topical skin lightener; unlike most skin products, a relatively high share of applied hydroquinone is absorbed. No animal studies and very limited human data (US label: use only if clearly needed). Skin lightening can wait: avoid in pregnancy, as melasma often fades after delivery.
- 哺乳
- Unknown Not studied in breastfeeding. LactMed: not contraindicated, but some experts advise against long-term use. If used, keep the infant's skin and mouth away from treated areas.

哪些人需要特別留意
- Depigmenting agent that may produce unwanted cosmetic effects if not used as directed.
- Test skin sensitivity first by applying a small amount to an unbroken skin patch and checking within 24 hours; stop if itching, vesicle formation or excessive inflammation occurs.
- Avoid contact with the eyes.
