Melasma
Also known as: Chloasma, Mask of pregnancy, Hyperpigmentation
Melasma is a common skin condition that causes brown or grayish-brown patches, usually on the face — particularly the cheeks, forehead, bridge of the nose, and upper lip. It results from overactive pigment-producing cells and is strongly driven by sun exposure and hormonal changes, which is why it often appears during pregnancy or with hormonal contraceptives. Melasma is harmless but can be cosmetically distressing and stubborn to treat.
Symptoms
Causes
- Sun exposure (UV and visible light stimulate pigment cells)
- Hormonal changes (pregnancy, oral contraceptives, hormone therapy)
- Genetic predisposition
- Certain medications and cosmetics that increase light sensitivity
- Heat
Risk Factors
- Female sex (far more common in women)
- Medium to darker skin tones
- Pregnancy
- Use of hormonal contraceptives
- Frequent sun exposure and family history
Diagnosis
- Visual examination by a dermatologist
- Wood's lamp examination to assess pigment depth
- Dermoscopy in some cases
- Skin biopsy rarely, to rule out other pigmentation disorders
Treatment
- Broad-spectrum sunscreen (including tinted/iron-oxide for visible light) — the cornerstone
- Topical lightening agents (hydroquinone, azelaic acid, kojic acid, tranexamic acid)
- Topical retinoids and combination 'triple creams'
- Chemical peels and laser/light therapy (carefully, to avoid worsening)
- Oral tranexamic acid in selected cases under medical supervision
- Stopping hormonal triggers when possible
Prevention
- Daily broad-spectrum sunscreen, reapplied regularly
- Wear wide-brimmed hats and seek shade
- Use tinted sunscreens that block visible light
- Avoid irritating skincare that can worsen pigmentation
- Discuss alternatives if hormonal contraceptives trigger it
When to See a Doctor
- Patches are spreading or not responding to sun protection
- You want prescription-strength treatment
- A pigmented spot changes in a way that concerns you (rule out other causes)
- Melasma is affecting your confidence or quality of life
