Hydroquinone works in two methods: it inhibits the exercise of tyrosinase (the enzyme that controls the synthesis of melanin) and will increase the cytotoxicity of melanocytes (it kills the cells that produce melanin).

Research present that hydroquinone works finest when used with a retinoid and a corticosteroid. Why? Retinoid hurries up mobile turnover, eradicating the uppermost, most broken, darker pores and skin layers. Corticosteroids assist scale back irritation.


Opposite to common opinion, it DOESN’T trigger most cancers (phew!). However, it might probably irritate pores and skin and, in uncommon instances, trigger ochronosis (provides pores and skin a bluish tint).

Ochronosis is extra frequent in individuals with darkish pores and skin. However it doesn’t appear to be brought on by hydroquinone alone (in any other case, everybody who makes use of it could get it). Utilizing hydroquinone with resorcinol or with out sunscreen appear to be the true triggers.

A 1996 research examined the efficacy of two related formulations of glycolic acid/hydroquinone and glycolic acid/kojic acid for melasma.

Sufferers used the cream with hydroquinone on one aspect of the face and the creme with kojic acid on the opposite. The outcomes?

Can You Use Hydroquinone And Kojic Acid Collectively?

However, science is evident on one factor: hydroquinone and kojic acid work finest when used collectively. A 1999 research in contrast the efficacy of a cream with 10% glycolic acid and a couple of% hydroquinone by itself and with the addition of two% kojic acid.

The primary cream lowered melasma in 47.5% of the sufferers. However  when kojic acid was added to the combo, the cream lowered the discolouration in 60% of sufferers.

The catch? Used collectively, hydroquinone and kojic acid are extra irritating. However the redness and stinging often disappears by the third week.

The Backside Line

Each hydroquinone and kojic acid are efficient at treating hyperpigmentation. They work even higher when used collectively. I like to recommend you begin with kojic acid as a result of it’s a bit of gentler and, if that doesn’t work, transfer onto hydroquinone or a combo of them.
