Melasma

Definition:

Melasma is a common skin condition characterised by brown or gray-brown patches of pigmentation, primarily on the face. It is more common in women and people with darker skin tones.

Symptoms of Melasma: Irregular, flat, brown or gray-brown patches

Most commonly seen on: Cheeks, forehead, bridge of the nose, upper lip, chin

Less commonly seen on neck or forearms (especially with sun exposure)

Factors leading to Melasma

1. Hormonal changes

Pregnancy (known as chloasma or “mask of pregnanc”)
Birth control pills or hormone replacement therapy

2. Sun exposure: Ultraviolet (UV) rays trigger melanin production, worsening the condition

3. Genetic predisposition: Family history increases risk

4. Cosmetics & skin irritants: Some skin products can irritate and worsen pigmentation

5. Thyroid disorders: May be associated with hormonal imbalance

Treatment/cure

Melasma may fade over time, especially after pregnancy or stopping hormonal medications, but persistent cases require treatment.

Topical treatments

Hydroquinone (skin-lightening agent)
Tretinoin and corticosteroids
Triple combination creams (Hydroquinone + Tretinoin + Corticosteroids)

Other treatments

Microdermabrasion
Laser therapy (used cautiously to avoid rebound pigmentation)
