What is Hydroquinone?
Hydroquinone is a topical cream that can reduce the appearance of melasma. Melasma is caused by an overproduction of melanin, the natural pigment produced by cells in your skin. Hydroquinone inhibits the production of melanin to help clear up dark spots associated with melasma.
How does Hydroquinone work?
Hydroquinone targets an enzyme called tyrosinase to block melanin production.1 Tyrosinase enzymes convert an amino acid called tyrosine into a compound called dopaquinone.2
Dopaquinone then goes through further reactions, depending on the tone of your skin, to form melanin pigments. So by inhibiting tyrosinase, Hydroquinone inhibits the production of melanin, reducing the amount of pigment in your skin.
What doses of Hydroquinone are there?
Hydroquinone is available in two doses for melasma. One contains 2% w/w of active ingredient, the other contains 4%. That means that 1 gram of treatment contains 20 mg of hydroquinone in the 2% strength cream, and 40 mg in the 4%. Right now, we only offer the 4% dose of Hydroquinone for melasma treatment.
What is the active ingredient in Hydroquinone?
Hydroquinone is a generic medicine, and gets its name from its active ingredient: hydroquinone. Itโs a depigmenting agent that blocks the production of melanin by your skin cells. This helps reduce pigmentation, and fade the appearance of dark spots.
