Hydroquinone is a depigmenting agent that works by inhibiting the enzymatic oxidation of tyrosine into melanin. It is widely indicated for the treatment of melasma, freckles, and post-inflammatory hyperpigmentation. This active ingredient is found in several verified generic formulations that provide effective skin-tone correction. Our platform ensures secure access to licensed treatments containing Hydroquinone for your dermatological needs.
Hydroquinone is a skin-lightening agent that belongs to the class of phenolic compounds. It has been used for many years to reduce the appearance of dark spots, melasma and other forms of hyperpigmentation. In the United Kingdom it is available only as a prescription-only medicine (POM) formulated mainly as a topical cream or gel. You will find hydroquinone listed as the active ingredient in a range of dermatology products.
Several prescription-only preparations include hydroquinone, most of them in a cream or gel base. Common strengths are 2 % and 4 % hydroquinone, and the products may be marketed under generic names such as “hydroquinone 2 % cream” or “hydroquinone 4 % gel”. Some combination creams pair hydroquinone with other agents like retinoic acid, corticosteroids or azelaic acid to enhance the lightening effect. In the UK these products are supplied by a number of manufacturers and are dispensed through pharmacies when a clinician has written a prescription. The exact brand name can vary, but the active ingredient remains hydroquinone.
Hydroquinone works by decreasing the production of melanin, the pigment that gives skin its colour. By slowing melanin formation, the visible darkened areas gradually become lighter over a period of weeks to months.
When applied to the skin, hydroquinone temporarily blocks an enzyme involved in melanin synthesis. This reduction in melanin production leads to a lightening of pigmented lesions. Effects are usually first noticed after several weeks of regular use, and the degree of improvement depends on the concentration of the preparation, the area being treated and the individual’s skin response. The action is limited to the outer layers of the skin, so systemic absorption is minimal.
These reactions are usually mild and disappear once the skin adapts or the product is discontinued.
If any of these signs appear, seek immediate medical attention.
Store hydroquinone creams at room temperature, away from moisture and direct heat. Most treatments are prescribed for a limited course-usually a few months-because prolonged use can increase the risk of irritation or rare skin changes. Always read the patient information leaflet that comes with your particular preparation and follow any instructions given by your pharmacist or prescribing clinician. Remember that each product containing hydroquinone may differ in strength, formulation and recommended duration of use.
Melanin: The natural pigment that gives skin, hair and eyes their colour.
Hyperpigmentation: Areas of skin that appear darker than the surrounding tone due to excess melanin.
Paradoxical hyperpigmentation: An unexpected darkening of skin that can happen in rare cases when using a lightening agent.
Prescription-only medicine (POM): A drug that can be supplied only with a prescription from a qualified prescriber in the UK.
