Topical Hydroquinone vs Tranexamic Acid for Melasma

Melasma is influenced by pigment-producing cells and triggers such as sunlight and visible light. Hydroquinone works directly on pigment production in the skin. Tranexamic acid is used in selected plans to reduce signals that can sustain pigmentation. Neither option replaces consistent light protection, and the best choice depends on the pattern, skin sensitivity, previous treatment, and clinician assessment.

A clinician may consider topical hydroquinone when the diagnosis is melasma and a direct pigment-reducing treatment is appropriate. It is usually applied only as instructed and reviewed rather than used indefinitely. Irritation can make pigmentation more noticeable, so introduce no extra scrubs, acids, or lightening products without advice. Stop and seek guidance for marked redness, swelling, blistering, or a new unusual colour change.

Tranexamic acid may be discussed when a clinician wants another way to address persistent pigment signalling, including for people who cannot tolerate or should not continue a particular topical course. The formulation and route matter; do not assume that a product intended for one route is suitable for another. Tell the clinician about clotting history, blood clots, stroke, migraine with neurological symptoms, pregnancy, and medicines that affect clotting.

Hydroquinone can cause irritation and, with inappropriate prolonged use, a difficult-to-treat dark or blue-grey colour change. Tranexamic acid requires medical screening because clotting-related history and some medicines may affect whether it is suitable, particularly when treatment is not purely topical. Daily broad-spectrum sunscreen, shade, hats, and attention to heat and visible-light exposure support either plan. Patch testing or a gradual start may be advised for sensitive skin.

Not every brown or grey patch is melasma. A single changing spot, a lesion that bleeds or crusts, or pigment with significant itch or inflammation should be examined rather than treated with a lightening cream. Post-inflammatory pigmentation, medication-related changes, and other pigment disorders may need different management. If the pattern is unclear, diagnosis comes before choosing a pigment treatment.

The recommendation is based on the pigment pattern, depth suggested by examination, skin tone, previous reactions, pregnancy status, medicines, and ability to maintain light protection. A clinician may select one treatment, combine compatible measures, or use a planned sequence with review. Melasma often needs maintenance because triggers can reactivate pigment. Ask how long to use the product, what changes should prompt a pause, and when progress will be reviewed.
