Is Sun Exposure the Main Cause of Melasma?
Melasma is one of the most common pigmentation disorders, especially among women with Indian skin. It appears as brown, greyish-brown, or tan patches, typically on the cheeks, forehead, nose, and upper lip. While many people believe that sun exposure is the only cause of melasma, the reality is more complex. If you’re considering Melasma Treatment in Delhi, understanding the underlying causes can help you choose the right treatment and prevent the condition from worsening.
What Causes Melasma?
Sun exposure is one of the biggest triggers for melasma, but it is not the only factor. Melasma is a multifactorial condition, meaning several internal and external factors can contribute to its development.
Common causes and triggers include:
Sun exposure: Ultraviolet (UV) rays stimulate melanocytes, the pigment-producing cells, leading to excess melanin production.
Hormonal changes: Pregnancy, birth control pills, hormone replacement therapy, and menstrual changes can trigger melasma.
Genetics: A family history of melasma increases the likelihood of developing the condition.
Heat exposure: Excessive heat from cooking, hot environments, or infrared radiation can worsen pigmentation, even without direct sunlight.
Thyroid disorders: Hormonal imbalances caused by thyroid conditions may contribute to melasma.
Certain medications: Some antibiotics, anti-seizure medications, and photosensitising drugs can increase pigmentation.
Although UV exposure is a major aggravating factor, many people develop melasma due to hormonal or genetic reasons, even if they spend very little time in the sun.
Why Sun Protection Is Still Essential
Even when sun exposure is not the original cause, it almost always worsens existing melasma. Daily sun protection is one of the most important steps in managing the condition.
Dermatologists recommend:
Using a broad-spectrum sunscreen with SPF 50+ every day.
Reapplying sunscreen every 2–3 hours when outdoors.
Wearing wide-brimmed hats, sunglasses, and protective clothing.
Avoiding prolonged sun exposure, especially between 10 a.m. and 4 p.m.
Consistent sun protection helps prevent existing pigmentation from becoming darker and reduces the chances of recurrence after treatment.
Effective Melasma Treatment Requires a Personalised Approach
Because melasma has multiple causes, there is no single treatment that works for everyone. A personalized treatment plan offers the best results.
Depending on your skin type and the severity of pigmentation, treatment may include:
Prescription topical creams containing tranexamic acid, azelaic acid, hydroquinone, or retinoids
Chemical peels to improve pigmentation
Laser and light-based therapies for selected patients
Oral medications when clinically appropriate
Medical-grade skincare combined with strict sun protection
An experienced dermatologist will assess your skin type, medical history, hormonal factors, and lifestyle before recommending the most suitable treatment plan.

Can sunscreen alone cure melasma?
No. Sunscreen helps prevent melasma from worsening, but it cannot remove existing pigmentation. Medical treatments are usually required for visible improvement.

Melasma is a chronic condition that can be effectively controlled with proper treatment and maintenance. While recurrence is possible, following your dermatologist’s advice can help keep pigmentation under control.
