Melasma Treatment in Nepal: The Evidence-Based Approach

Understanding Melasma in Nepal

Melasma (also called chloasma, or "the mask of pregnancy") is a chronic acquired hyperpigmentation disorder characterised by symmetric, irregular patches of brown or grey-brown pigmentation on UV-exposed facial areas.

The classic distribution:

• Centrofacial: forehead, nose, upper lip, chin (most common pattern)
• Malar: cheeks and nose
• Mandibular: jawline and lower cheeks (less common)

Melasma is significantly more common in South Asian women — the population type that makes up much of Nepal's demographics. Fitzpatrick Skin Types III–V (medium to dark complexions) have higher baseline melanocyte activity and are more prone to UV-triggered hyperpigmentation responses.

Why women are predominantly affected: The female sex hormones oestrogen and progesterone upregulate melanocyte-stimulating hormone (MSH) receptors and directly increase melanocyte activity. This explains:

• High prevalence during pregnancy ("mask of pregnancy")
• Worsening on combined oral contraceptive pills
• Improvement after menopause in some women

Why Sun Protection Is Non-Negotiable for Melasma

Without strict, daily broad-spectrum photoprotection, NO topical treatment for melasma will succeed. UV light:

• Directly stimulates melanocytes to produce melanin
• Activates melanocortin receptors that perpetuate abnormal melanocyte activity
• Generates free radicals that oxidise DOPA (a melanin precursor), accelerating pigmentation
• Stimulates keratinocytes to produce paracrine signals that activate melanocytes

Applying a brightening cream at night and then going out in daylight without SPF is self-defeating — you spend your evening undoing the damage UV does during the day.

For melasma: Use a broad-spectrum SPF 50 every morning and reapply every 2 hours outdoors.

Best SPF options for melasma:

• UVedge Tinted SPF50 Sunscreen — provides light coverage that helps conceal melasma while protecting it from UV
• UVedge Soft Mineral SPF-50 Gel — mineral zinc oxide protects against both UV and visible light (which also triggers melanocytes in melasma patients)
• UVedge SPF 50 Gel — daily use chemical broad-spectrum SPF

Topical Treatment: The Evidence Base

First-Line: Tranexamic Acid

Tranexamic acid (TXA) has emerged as one of the most effective and well-tolerated topical treatments for melasma. Its mechanism:

• Inhibits UV-induced activation of plasminogen in keratinocytes
• Reduces prostaglandin synthesis that normally stimulates melanocyte activity after UV exposure
• Has been shown in clinical trials to significantly reduce melasma pigmentation scores (MASI — Melasma Area and Severity Index) after 12 weeks of use

Lumiedge TX Cream from Aurelderma contains tranexamic acid as its primary active, formulated for localised melasma treatment on the face.

Complementary: Niacinamide

Niacinamide inhibits the transfer of melanosomes from melanocytes to keratinocytes — a different mechanism from tranexamic acid. Used in combination, they address two distinct steps in the pigmentation pathway.

Niafine Serum is the niacinamide delivery vehicle — apply first as a leave-on serum, then Lumiedge TX Cream on melasma-affected areas.

Vitamin C

Inhibits tyrosinase and reduces melanin precursor oxidation. Agelite Vitamin C Face Wash provides vitamin C contact during the cleanse step without the stability issues of leave-on vitamin C.

The Classic Triple Combination (Rx)

The traditional prescription treatment for severe melasma is the Kligman formula — a combination of hydroquinone 4%, tretinoin 0.05%, and a corticosteroid. This requires dermatological prescription and supervision due to risks of ochronosis (paradoxical darkening) and corticosteroid side effects with long-term use. For mild-to-moderate melasma, the evidence-based OTC combination of TXA + niacinamide + SPF offers an effective and safer alternative.

Melasma Treatment Routine

Morning

1. Agelite Vitamin C Face Wash — vitamin C during cleanse, blocks melanin synthesis
2. Niafine Serum — leave-on niacinamide, inhibits melanin transfer
3. Lumiedge TX Cream — tranexamic acid on melasma patches (allow to absorb before SPF)
4. UVedge Tinted SPF50 — broad-spectrum protection + light coverage of pigmentation

Evening

1. Gentle cleanser (Moisoft Cleanser)
2. Niafine Serum
3. Lumiedge TX Cream — apply to affected areas
4. Moisturiser (Moisoft Lotion or Ceraedge Cream if dry skin)

Other Factors That Worsen Melasma

Heat: Infrared and visible light can trigger melanocytes in melasma patients without UV. Avoid prolonged heat exposure (steam baths, very hot environments). This is also why some patients notice worsening from cooking over open fires.

Hormonal contraception: Women who develop melasma on the pill should discuss alternatives with their gynaecologist — some progestins are more associated with melasma than others.

Fragranced products on affected areas: Some fragrance compounds are phototoxic — they increase skin sensitivity to light and can worsen melasma. Use fragrance-free products on melasma-affected skin.

Thyroid dysfunction: Thyroid hormones modulate melanocyte activity — uncontrolled thyroid disease can worsen melasma. Check TSH if melasma is unusually severe or unresponsive to treatment.

When to See a Dermatologist

See a dermatologist for melasma if:

• Melasma is severe (covering large facial areas, dark pigmentation)
• Topical treatment has not produced visible improvement after 16 weeks
• You need to consider prescription treatments (tretinoin, hydroquinone, chemical peels)
• Laser treatment is being considered (note: laser must be done with care in darker skin types — inappropriate laser treatment can worsen melasma)

Summary

Melasma is a chronic pigmentation disorder requiring long-term management. The cornerstone of treatment is strict daily SPF 50 — without it, no topical treatment will succeed. Topical tranexamic acid (Lumiedge TX Cream) and niacinamide (Niafine Serum) target two different steps in the pigmentation pathway. Patience is essential — significant improvement typically requires 12–16 weeks of consistent treatment.
