What should you know about glutationa melasma?

Melasma causes recurring brown or grey-brown patches, often on the face, when pigment-producing cells become more active. Sunlight and visible light can deepen it, and hormonal changes may contribute. A product marketed as a brightener does not confirm that a patch is melasma.

If facial discoloration is new or the diagnosis is uncertain, a dermatology examination can distinguish melasma from other causes of dark patches. Irritation from aggressive products may leave additional uneven tone, particularly in skin that marks easily after inflammation.

Use daily broad-spectrum sunscreen, protective clothing, and shade; reapply sunscreen as directed when outdoors. Keep skincare gentle and stop products that burn or sting. A dermatologist may discuss prescription pigment treatments or options such as [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/), [Microneedling](/treatments/aesthetic-procedures/microneedling/), [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/), or [Laser Toning](/treatments/laser-and-energy/laser-toning/), depending on the pattern and your skin type.

Learn more about [Melasma](/conditions/melasma/), [Sun-Damaged Skin](/conditions/photoaging/), [Dark Patches On Skin](/symptoms/dark-patches-on-skin/), and [Uneven Skin Tone](/symptoms/uneven-skin-tone/) before choosing a procedure.

Book a dermatology review for a rapidly changing, bleeding, painful, or one-sided mark, or when pigmentation affects the eyes or is accompanied by other new symptoms. Seek urgent help after a treatment for facial swelling, breathing difficulty, severe blistering, eye pain, or rapidly worsening redness.

Ask whether the pattern is melasma, what may be triggering it, whether glutathione is suitable, how to prevent rebound darkening, and which treatment can be adjusted safely for your skin tone.
