Hydroquinone in Skincare: Rules, Risks and Alternatives
Hydroquinone is a skin-lightening ingredient used on dark patches. In Australia, the TGA says products with more than 2% hydroquinone for therapeutic or cosmetic use need a prescription.
TL;DR
- What it is: a skin-lightening ingredient used for hyperpigmentation.
- Australian rule: the TGA says products with more than 2% hydroquinone require a prescription.
- The risk: a systematic review links long-term hydroquinone use with exogenous ochronosis, a blue-black skin discolouration.
- The trap: the TGA found imported lightening creams that contained more hydroquinone than their labels declared.
- The alternatives: shop-bought brightening ingredients include kojic acid, alpha arbutin and tranexamic acid.
- Our position: we don't use hydroquinone in any of our products.
What is hydroquinone?
Hydroquinone is a lightening ingredient used to fade dark patches such as melasma and sun spots. It has been used for decades, and it is also among the most debated skincare ingredients.
It is a medicine-grade ingredient in Australia at higher strengths, which is why you will not find strong versions on a regular shelf.
Is hydroquinone legal in Australia?
In Australia, products with more than 2% hydroquinone for human therapeutic or cosmetic use require a prescription, according to the TGA. The TGA also says concentrations of 2% or higher indicate a medicine, listed in Schedule 4 of the Poisons Standard.
The TGA has taken action on imported lightening products such as Caro White and Carotone. Its testing found hydroquinone above 2%, higher than the label declared, and the TGA said supplying them in Australia is illegal because they are not on the Australian Register of Therapeutic Goods.
The TGA page does not set out what applies at or below 2%. If you are unsure about a product, ask a pharmacist or GP.
What are the risks of hydroquinone?
The best-known risk is exogenous ochronosis, a blue-black darkening of the skin. A systematic review in PubMed collected the reports of ochronosis associated with hydroquinone.
Using an unregulated cream is the bigger problem, because you cannot be sure what is in it or how much.
If a dark patch is new, changing or uneven, see a GP first. Some pigmented marks need a proper diagnosis before any cream.
How does hydroquinone compare with shop-bought brightening ingredients?
| Ingredient | Status | Good to know |
|---|---|---|
| Hydroquinone | Prescription above 2% in Australia | Medicine-grade, used under advice |
| Kojic acid | Sold in cosmetics | A common brightening ingredient |
| Alpha arbutin | Sold in cosmetics | Often used in brightening serums |
| Tranexamic acid | Sold in cosmetics | Has its own guide in our library |
| Azelaic acid | Sold in cosmetics | Also used for blemish-prone skin |
Each of these has its own guide. None of them is a like-for-like swap for a prescription product.
How do you spot hydroquinone on a label?
Look for "Hydroquinone" in the ingredient list. Some imported creams do not list it at all, or list a lower strength than the cream contains.
A typical line might read: Water, Glycerin, Hydroquinone, Sodium Metabisulfite. Buy lightening products from a pharmacy or a brand that shows a full ingredient list, and avoid unlabelled jars.
Who should skip hydroquinone or go slow?
Skip any lightening cream with no ingredient list, a vague label or a promise of rapid results. If you are pregnant or breastfeeding, ask a GP or pharmacist before using a lightening product.
Patch test anything new using our patch testing guide. Daily sunscreen matters with any pigment product, because UV can darken marks again.
Do we use hydroquinone at Dope Skin Co?
No. Hydroquinone is not in any of our products.
