氢醌（hi-dro-kwi-non）是一种皮肤美白剂，也存在于植物和动物体内。它可用于局部涂抹，以淡化色素沉着或皮肤变黑的部位。
氢醌（浓度最高可达 4%）只能由持牌医生开具处方，以乳膏、乳液、凝胶或溶液的形式使用。它可以作为单一的外用产品，也可以作为其他处方药物中的成分。
如需了解氢醌是否适合您，请预约咨询。
氢醌通过抑制皮肤中的黑色素细胞（melanocytes）来发挥作用。黑色素细胞是产生黑色素（melanin）的细胞，而黑色素决定了皮肤的颜色。
当皮肤出现色素沉着或变黑（如黄褐斑、老年斑/日晒斑、雀斑、咖啡斑）时，这些区域的黑色素含量较高，是由于黑色素细胞的活跃度增加所致。
因此，通过减少治疗部位的黑色素细胞活性，氢醌可以逐渐均匀肤色。
通常，皮肤美白效果在 约 4 周后 开始显现。
具体见效时间取决于色素沉着的类型和严重程度、患者的肤色以及治疗后是否做好防晒措施。对于某些人来说，可能需要数月的持续使用才能达到最佳效果。
部分患者可能更倾向于选择其他治疗方案，例如抗色素沉着激光、Ethosome Gold PTT 以及射频黄金微针（Sylfirm X、Morpheus 8、Secret RF）。
氢醌可用于治疗多种与色素沉着相关的皮肤问题，包括但不限于：
FAQ
Yes, when prescribed by a licensed doctor. Historically, there have been a number of safety concerns about hydroquinone. But the U.S. Food and Drug Administration confirmed that hydroquinone only be prescribed by a doctor at a maximum of 4 percent concentration.
Some side effects such as dryness and irritation are not unusual, especially if you have dry or sensitive skin. We recommend applying a moisturiser after. These side effects may also taper off as your skin adjusts to the ingredient.
If any of the following effects persist or become severe, consult your doctor:
Stop using hydroquinone and consult your doctor if the following occurs:
A very serious allergic reaction to hydroquinone is rare. However, seek immediate medical attention if you exhibit symptoms of a serious allergic reaction such as hives, difficulty breathing, swelling of face, lips, tongue, or throat.
Generally, we recommend applying hydroquinone to the affected area 1 to 2 times a day for 3 to 6 months. If improvements are not seen after 2 to 3 months of consistent use, discontinue use.
At SL Aesthetic Clinic, we prefer using hydroquinone as a concentrated treatment to address an immediate hyperpigmentation concern. We do not offer it as a means to maintain results for the long term.
Hydroquinone is a viable treatment of choice for those suffering from pigmentary problems such as melasma, sun spots, age spots, post-inflammatory hyperpigmentation and more.
Pre-treatment instructions: ensure that you’re in a good state of health. Always disclose your full medical history during consultation (e.g., asthma).
Women should also tell your doctor if you are pregnant, planning for pregnancy, or are breast-feeding.
Inform your doctor if you have other skin conditions (e.g., eczema, psoriasis) or have any unusual or allergic reactions to any ingredients or topicals.
Post-treatment instructions: apply a moisturiser after treatment. Avoid prolonged sun exposure, tanning booths, and sunlamps. Always use sunscreen. And wear protective clothing over treated areas, if possible.
