Hydroquinone

Ingredient · In our Dark Spot Treatment

Hydroquinone

Hydroquinone is the classic dark-spot fader. It slows down melanin, the pigment that makes spots and melasma darker, and it's used for a set period under a clinician's eye.2

Prescription only, short-term use

Hydroquinone is part of an FDA-approved prescription cream for short-term treatment of melasma.2 It can no longer be sold over the counter: FDA says OTC hydroquinone products are unapproved drugs.1 Our creams are compounded by a licensed pharmacy, and compounded versions are not FDA-approved.4

FDA-approved for this useWell studied, used off-labelEarly evidenceLittle or no human data

The studies below used FDA-approved products or other forms. Our compounded version hasn't been studied in trials, and results may differ.

What it is

Hydroquinone blocks a step in how skin makes melanin. Less new pigment means dark patches can gradually fade.2

Why it's in this product

Dark spots and melasma often get more noticeable in midlife, and hydroquinone has decades of use behind it. In our Dark Spot Treatment it's paired with other brighteners and a calming steroid.

What the studies in people show

  • Systematic reviewThe benchmark other treatments get compared toIn a Cochrane review of 20 melasma studies, hydroquinone was part of the most effective option, a triple cream with tretinoin and a steroid. That cream beat hydroquinone alone.3
  • Randomized trialMatched by tranexamic acid in one small trialIn a split-face trial of 50 women, a 3% hydroquinone solution with a little steroid improved melasma about as much as 3% tranexamic acid over 12 weeks.5

What we don't know yet

Melasma studies were generally small, short and of poor quality, and melasma often returns.3 That's why the FDA-approved hydroquinone cream is meant for short-term use, not maintenance.2

Safety, in plain English

Common side effects include redness, peeling, burning and dryness.2 With longer or unsupervised use, hydroquinone can cause ochronosis, a gradual blue-black darkening of the skin that may be permanent. FDA has warned about this with OTC products.1,2 That's why it's used for a set period, with check-ins.

A licensed clinician reviews your health history and decides whether this cream is appropriate for you. Exploring it here never means you'll get a prescription.
