Pigmentation
What is Pigmentation?
Pigmentation refers to discolouration of the skin, caused by an overproduction or uneven distribution of melanin, the pigment responsible for skin colour. It can appear as dark patches, spots, or uneven skin tone.
Causes
Sun Exposure
- UV radiation stimulates melanin production → freckles, sunspots, or general darkening.
Hormonal Changes
- Pregnancy (melasma), birth control pills, or hormone therapy can trigger pigmentation.
Inflammation / Skin Injury
- Post-inflammatory hyperpigmentation (PIH) from acne, cuts, burns, or eczema.
Genetics
- Some individuals are genetically predisposed to uneven pigmentation.
Lifestyle & Environmental Factors
- Smoking, stress, and poor diet can exacerbate pigmentation.
- Certain medications or cosmetics may trigger pigmentation changes.
Symptoms / Appearance
- Dark patches on the skin.
- Freckles, sunspots, melasma, or post-inflammatory marks.
- Uneven skin tone – can be localized or widespread.
- Often occurs on face, neck, hands, and arms.
- Can be flat or slightly raised, depending on cause.
Treatments
Professional Treatments
- Topical depigmenting agents – hydroquinone, kojic acid, azelaic acid, tranexamic acid.
- Chemical peels – glycolic acid, salicylic acid, or TCA peels for surface pigmentation.
- Laser therapy / IPL – targets excess melanin for stubborn pigmentation.
- Microneedling with brightening serums – enhances absorption and skin renewal.
- Prescription creams – combination treatments for melasma or severe PIH.
At-Home & Skincare Support
- Daily broad-spectrum SPF 30+ – essential for prevention and treatment.
- Antioxidants – vitamin C, niacinamide, or green tea extracts to lighten and protect.
- Gentle skincare – avoid harsh scrubs that aggravate pigmentation.
- Moisturisers – maintain skin barrier function.
Prevention
- Strict sun protection – SPF, hats, sunglasses, and shade.
- Avoid triggers like harsh products, picking at skin, or excessive heat.
- Healthy lifestyle – balanced diet, hydration, and avoiding smoking.
- Regular monitoring – early treatment prevents worsening.

Not always – some pigmentation fades with treatment and sun protection, while others may persist.

Often yes, but some melasma patches may persist and require treatment.
Q3. Can skincare alone remove pigmentation?
Skincare helps lighten and prevent, but professional treatments are often needed for stubborn or deep pigmentation.
