Melasma Triggers You Didn’t Even Know About
Melasma Triggers You Didn’t Even Know About
Melasma is one of the most frustrating forms of pigmentation to treat. While many people know that sunlight can worsen melasma, few realise that numerous hidden triggers can stimulate pigment-producing cells and cause dark patches to become more noticeable, spread, or return after treatment.
What Is Melasma?
Melasma is a chronic pigment disorder that causes brown, grey-brown, or tan patches to develop on the skin. It most commonly affects the forehead, cheeks, upper lip, chin, and jawline.
Often referred to as hormonal pigmentation, melasma occurs when melanocytes, the cells responsible for producing pigment, become overactive and produce excess melanin.
Sun Exposure & Free Radicals: The Main Melasma Triggers
Melasma is not just triggered by sun exposure from UVB and UVA rays. It is also heavily influenced by Visible Light, heat, and Infrared-A radiation generated by the sun, as well as free radicals produced by sun exposure and other environmental stressors.
- UVB (The Melanin Producer): Damages cellular DNA and causes immediate inflammation (sunburn). This triggers melanocytes (pigment cells) to flood the skin with defensive melanin, causing instant dark spots.
- UVA (The Pigment Darkener): Penetrates deeply into the dermis year-round, even through glass. It instantly oxidises existing melanin (making it darker) and destroys collagen, trapping pigment deep within the skin.
- Visible Light (The Stubborn Pigment Maker): Emitted by the sun and digital screens, this light penetrates deeper than UVA. It activates a receptor called Opsin 3, triggering highly stubborn, long-lasting pigmentation.
- Infrared-A (The Heat Generator): Thermal energy from the sun (even in the shade), or prolonged exposure to heat dilates blood vessels and promotes angiogenesis (new blood vessel growth), releasing inflammatory proteins which triggers pigment production.
- Free Radicals (The Skin Damager): These are unstable molecules generated by multiple sources, like sun exposure, heat, air pollution or alcohol. They cause oxidative stress, which essentially leads to melanocytes constantly overproducing pigment.
Why Standard Sun Protection Is Not Enough
Sunscreens from standard pharmacies or salons often fall short when it comes to melasma because they lack the specific filters, ingredients, and oral supplements needed to protect against UVA, Visible Light (VL), Infrared-A (IR-A), and free radical damage.
The Wrong Product: Clear chemical or mineral sunscreens lack iron oxides, meaning they offer zero protection against Visible Light. They also fail to neutralize heat-induced damage.
The Right Product: Melasma requires an SPF 50+ explicitly labeled “Broad Spectrum” or “PA++++” to stop UVA. It must contain iron oxides (tinted formulas) to block Visible Light, and topical antioxidants to neutralize Infrared-A heat.
Oral Sun Protection: Daily Heliocare 360° Capsules act as an internal shield. They neutralise free radicals before they can signal pigment cells to overproduce melanin. Clinical research shows adding these capsules to topical SPF results in a faster, greater reduction in melasma size and intensity than using sunscreen alone.
Reapplication Matters: Sunscreen degrades and must be reapplied every 4 hours indoors to protect against window glare and digital screens.
Outdoor Rules: Sunscreen must be reapplied every 2 hours outdoors. This should be combined with shade, wide-brimmed hats, and UV-protective sunglasses to fully prevent flare-ups.
Environmental Triggers That Can Worsen Melasma
Many environmental factors can stimulate melanocytes and worsen pigmentation, even without direct sun exposure.
Heat Triggers: Saunas, steam rooms, jacuzzis, hot tubs, hot yoga, overly hot showers, prolonged cooking, and high heat settings on hair dryers may worsen melasma.
Light Triggers: High-Energy Visible (HEV) light from phones, computers, and LED screens may stimulate melanocytes, particularly in darker skin types.
Product Triggers: Perfumed skincare products, artificial fragrances, citrus oils, bergamot oils, and essential oils may cause low-grade irritation that contributes to pigmentation.
Treatment Triggers: IPL, BBL, laser treatments, microneedling, radio frequency treatments, aggressive chemical peels, waxing, threading, and plucking may worsen pigmentation in susceptible individuals.
Stress and Melasma: The Overlooked Connection
Hormonal changes are one of the most common underlying causes of melasma.
Hormonal Changes: Pregnancy, oral contraceptives, hormone replacement therapy, menopause, and hormonal imbalances may trigger or worsen pigmentation.
New Medication: Certain medications may increase photosensitivity or affect pigment production, making the skin more prone to developing dark patches.

Hormonal Triggers and Medication Impact
Ageing and sun-damaged skin develop when the skin’s structural components, particularly collagen and elastin, are broken down over time by UV exposure and natural ageing. This leads to thinning skin, uneven tone, wrinkles, and loss of firmness.
- Hormonal Changes: Affect the outer layer (epidermis), causing surface thinning, dryness, and uneven texture.
- New Medication: Penetrate deeper into the dermis, damaging collagen and elastin, resulting in sagging and wrinkles.
