Melasma: Causes, Prevention & Evidence-Based Care

May 31, 2019

Symmetrical pigment swatches with sunscreen and sun-protection elements

Quick answer: Melasma is a chronic, relapsing pigment condition that typically causes symmetrical brown or gray-brown facial patches. Light exposure, hormones, genetics and heat may contribute. It is not limited to pregnancy, and effective management often combines protection, gentle skincare and dermatologist-guided treatment.

Essential points

  • Melasma is a medical diagnosis, not just a generic dark spot.
  • Both ultraviolet and visible light can contribute.
  • Pregnancy and prescription-treatment decisions require clinician guidance.

What melasma looks like

Melasma often appears on both sides of the cheeks, forehead, upper lip, nose or jawline. The pigment may sit at different depths, which affects color and response. A clinician can distinguish melasma from post-inflammatory hyperpigmentation, sun-induced lesions and other causes.

What can trigger or maintain it

  • Ultraviolet radiation
  • Visible light
  • Hormonal changes, including pregnancy or hormonal medications
  • Genetic predisposition
  • Skin irritation and sometimes heat exposure

Because triggers overlap, melasma commonly returns even after improvement.

Sun and visible-light protection

Use broad-spectrum, water-resistant SPF 30 or higher every day. Dermatology guidance often recommends tinted sunscreen with iron oxides because it can add visible-light protection. Hats, shade and consistent reapplication when outdoors also matter.

Skincare ingredients and professional treatment

Dermatologists may recommend hydroquinone, tretinoin, combination prescriptions, azelaic acid, tranexamic acid or procedures depending on the patient. These options have different risks and are not interchangeable. Cosmetic ingredients such as vitamin C can support antioxidant and tone goals but should not be presented as a cure.

Review ingredients used for hyperpigmentation and vitamin C for dark spots for supportive skincare context.

Pregnancy and nursing

Do not assume that “natural” means pregnancy-safe. Retinoids are avoided in pregnancy, and prescription or concentrated active choices should be reviewed with an obstetric clinician or dermatologist. Sunscreen and a gentle routine remain important, but individual recommendations belong to your healthcare team.

Avoid making melasma worse

Harsh peels, aggressive scrubbing and repeated irritation can deepen post-inflammatory discoloration. Introduce one product at a time and stop if it burns or inflames the skin. Choose providers experienced in treating your skin tone before a procedure.

Melasma should be diagnosed and managed with a qualified healthcare professional, especially during pregnancy or nursing.
