Hyperpigmentation on Indian Skin: 7 Types, What’s Causing Yours, and How Dermatologists Treat Each

Type 1: Post-Inflammatory Hyperpigmentation (PIH) from Acne — Most Common in India

PIH is the dark or reddish-brown flat mark left behind after a pimple heals. It is not a scar. The skin texture is smooth, but melanin has been deposited in the area as a result of the inflammation from the acne lesion.

In Indian skin, the melanocyte response to acne inflammation is substantially stronger than in lighter skin types. A pimple that might leave a faint pink mark on Fitzpatrick type II skin can leave a deep brown mark on Fitzpatrick type V skin. Without any treatment, PIH on Indian skin takes 6 to 18 months to fade significantly. Many patients never see full clearance without intervention.

Common patient descriptions: “dark spots after pimples,” “acne marks that won’t go,” “my skin has cleared but I still have patches.”

Treatment for PIH:

• Niacinamide 10%: inhibits melanin transfer from melanocytes to skin cells; well tolerated, suitable for daily long-term use
• Alpha arbutin 1-2%: gentle tyrosinase inhibitor; suitable for all skin types including sensitive skin
• Azelaic acid 10-15%: both a tyrosinase inhibitor and an anti-inflammatory; dual benefit for active acne plus PIH
• Vitamin C (L-ascorbic acid) 10-20%: inhibits melanin synthesis; use in the morning with SPF
• Retinoids (adapalene 0.1% or tretinoin 0.025-0.05%): accelerate cell turnover, speeding fading; use at night
• SPF 50 PA+++ or PA++++ every morning: essential; without SPF, treated marks darken again with any sun exposure

Professional options: Q-switched ND:YAG laser, glycolic acid or lactic acid chemical peels, Pico laser for stubborn marks.

Type 2: Melasma

Melasma presents as symmetrical brown or grey-brown patches, most commonly on the cheeks, upper lip, forehead, and nose bridge. It is driven by hormonal triggers (oestrogen and progesterone) combined with UV exposure. This is why it is significantly more common in women, particularly during pregnancy, while on hormonal contraception, or during perimenopause.

India’s UV intensity worsens melasma considerably compared to countries at higher latitudes. Many Indian women notice their melasma is substantially darker in summer and slightly improved in winter.

Three subtypes of melasma (relevant for treatment selection):

• Epidermal melasma: melanin in the surface layers; responds well to topical treatments and chemical peels
• Dermal melasma: melanin deposited deep in the dermis; responds poorly to topicals alone; requires laser
• Mixed melasma: both layers involved (the most common type)

Treatment for melasma:

• Triple combination cream (hydroquinone 4% + tretinoin 0.05% + mild corticosteroid): the most prescribed first-line prescription treatment in India; requires dermatologist supervision; do not use for longer than 2-3 months continuously
• Tranexamic acid: available as a topical (2-5%) and oral tablet (250mg twice daily with meals); strong evidence for melasma; widely prescribed by Indian dermatologists
• Chemical peels: glycolic acid 30-70%, lactic acid, or Jessner peels at the clinic; accelerate topical treatment
• Q-switched or Pico laser: for mixed and dermal components
• Strict SPF: PA++++ broad-spectrum, reapplied every 2-3 hours outdoors or indoors, without this, all treatment is undermined

If you are pregnant: tretinoin and hydroquinone are not safe. Azelaic acid 15-20%, glycolic acid products, Vitamin C serum, and physical SPF (zinc oxide, titanium dioxide) are the safe options during pregnancy. Discuss all skincare with your obstetrician.

Important: melasma is a chronic condition. It recurs with hormonal changes and UV exposure. Patients who clear their melasma with treatment need a maintenance protocol (usually azelaic acid, niacinamide, and strict SPF) to prevent recurrence.

Type 3: Solar Lentigines (Sun Spots / Age Spots)

Solar lentigines are flat, discrete, uniformly pigmented spots on sun-exposed areas: cheeks, forehead, nose bridge, the back of hands. They represent focal concentrations of melanin from cumulative UV exposure over years, not from any single sun event.

In India, solar lentigines tend to appear earlier than in Western countries, typically from the early 30s, because of higher UV intensity year-round. Patients often mistake them for PIH from old acne, but the distinction is location (sun-exposed areas only), shape (round, well-defined), and history (no preceding pimple or injury at that spot).

Treatment: Q-switched ND:YAG laser is the most effective single treatment for solar lentigines, typically 2-4 sessions. IPL is also effective. Topical vitamin C and strict SPF prevent new ones from forming and stop existing ones from darkening.

Type 4: Periorbital Hyperpigmentation (Under-Eye Dark Circles)

Under-eye dark circles are one of the most common dermatology queries in India, and one of the most frequently mistreated, because dark circles have four distinct causes and each requires a different approach.

Four subtypes:

Pigmentation type (brownish): melanin deposits in the under-eye skin. Worsens with sun exposure. Responds to topical Vitamin C, niacinamide, and SPF, as well as Q-switched laser and chemical peels for the delicate under-eye area.

Vascular type (bluish-purple): the under-eye skin is thin and blood vessels show through. Worsened by fatigue, dehydration, and allergies. Topicals have limited effect; caffeine eye creams help temporarily; allergy treatment and sleep improvement are key.

Structural type (hollowing and shadow): volume loss under the eye creates a shadow, not actual pigmentation. No cream treats this; dermal filler placed by an experienced injector is the most effective treatment.

Mixed type: most patients have more than one contributing factor.

A dermatologist can identify which subtype is dominant in a clinical examination. Treating a structural dark circle with pigmentation creams (as most home-remedy content recommends) produces no result because there is no pigmentation to treat.

Type 5: Freckles (Ephelides)

Freckles are small, flat, reddish-brown spots caused by a genetic tendency for uneven melanin distribution. Unlike solar lentigines, they appear in childhood or early adolescence and have a characteristic seasonal pattern: darker in summer, lighter in winter, as UV activates the melanocytes in freckled skin.

Freckles are less common on deep Indian skin (Fitzpatrick V-VI) but appear on Fitzpatrick III-IV. They are frequently confused with PIH from old acne on Indian skin. The distinguishing feature: freckles precede any inflammation and darken with sun; PIH follows inflammation and does not change seasonally.

Treatment: Q-switched laser and IPL are effective for freckle reduction. Broad-spectrum SPF prevents seasonal darkening. Results are maintained with sun avoidance; freckles return without it.

Type 6: Lichen Planus Pigmentosus (LPP) — India-Specific

LPP is a form of inflammatory skin condition that deposits melanin in the deep dermis rather than the surface layers. This single fact explains why it is both frequently misdiagnosed as melasma and why standard melasma treatments fail on it.

Pattern: dark grey-brown patches on the face, neck, and sometimes body folds. Unlike melasma, LPP does not follow UV exposure. It can appear in areas that do not receive much sun, such as the sides of the neck, armpits, and inner arms.

Why this matters for Indian patients: LPP is significantly more prevalent in South Asian and Middle Eastern populations than in Western populations. It is estimated to be one of the most under-recognised causes of facial pigmentation in Indian dermatology. Many patients spend months or years on triple combination creams for “melasma” with no improvement, because the condition is actually LPP.

Diagnostic clue: if you have tried 8-12 weeks of triple combination cream with no improvement, LPP should be considered. The diagnosis is clinical and can be confirmed by skin biopsy if needed.

Treatment: because the melanin is in the dermis, topical tyrosinase inhibitors (hydroquinone, kojic acid, arbutin) have limited effect. Q-switched ND:YAG laser and Pico laser, which can target dermal melanin, are the treatments of choice. Tacrolimus 0.1% ointment addresses the underlying inflammatory component.

Type 7: Drug-Induced Hyperpigmentation

Several medications cause skin darkening as a side effect:

• Antimalarials (chloroquine, hydroxychloroquine): blue-grey or brown pigmentation on the face, shins, and mucous membranes. Hydroxychloroquine is widely prescribed in India for lupus, rheumatoid arthritis, and malaria prevention.
• Minocycline (antibiotic, used for acne): blue-grey discolouration, typically in acne scars or sun-exposed areas
• Amiodarone (cardiac medication): blue-grey pigmentation on sun-exposed areas
• Some chemotherapy agents: diffuse darkening

Drug-induced pigmentation is often missed because GPs and patients do not connect a skin change to a medication the patient has been on for months. If you develop diffuse pigmentation without a clear UV or inflammatory trigger, mention all current medications to your dermatologist.

Management: identification and dose reduction or substitution of the causative drug (with the prescribing physician’s guidance) is the first step. Q-switched laser can address residual pigmentation after the drug is stopped or reduced.

Note on unsafe OTC products in India: many unlabelled or cheaply imported skin lightening creams contain mercury, high-concentration steroids, or undisclosed hydroquinone. Long-term steroid use causes skin thinning, steroid acne, and rebound darkening. If a cream works unusually fast or makes skin feel thin or fragile, stop using it and see a dermatologist.

Chemical Peels (Glycolic, Lactic, TCA, Jessner)

Accelerate cell turnover, removing surface pigmentation faster than topicals alone. Glycolic and lactic acid peels (20-70%) are suited for PIH and surface melasma. TCA peels address deeper pigmentation. Chemical Peels on Indian skin require experienced application to avoid post-peel hyperpigmentation from incorrect concentrations or aftercare.

Q-Switched ND:YAG Laser

Delivers nanosecond pulses of laser energy that are selectively absorbed by melanin, breaking pigment deposits into particles cleared by the lymphatic system. Effective for PIH, solar lentigines, freckles, LPP, and periorbital pigmentation. When operated at correct parameters for Fitzpatrick IV-VI skin, Q-switch is safe on Indian skin. Incorrect settings cause paradoxical post-inflammatory hyperpigmentation, which is why operator experience on darker skin is critical.

Pico Laser

Ultra-short pulse duration (picoseconds vs nanoseconds in Q-switch) causes less thermal injury to surrounding tissue while effectively shattering melanin deposits. Suitable for stubborn pigmentation that has not responded to Q-switch alone, and for the lighter passes needed on sensitive or darker skin tones.

IPL (Intense Pulsed Light)

Broad-spectrum light energy targeting melanin and vascularity. Effective for sun damage, freckles, and solar lentigines. Requires careful energy settings on Fitzpatrick IV-VI skin; higher energy settings can cause burns or post-treatment hyperpigmentation in untrained hands.

See a dermatologist if:

• Pigmentation has not improved after 3 months of consistent topical treatment combined with daily SPF
• You have been using an OTC cream for melasma that makes your skin feel thin, burns, or causes new breakouts (signs of unlabelled steroids)
• Patches are growing, changing shape, or have multiple colours within them (asymmetry and colour variation warrant a clinical check to rule out other diagnoses)
• You have tried multiple products for 6 months or more without a clear diagnosis of which type of hyperpigmentation you have

Getting the correct type diagnosed first saves months of using the wrong products. PIH from acne, LPP, and melasma look similar but respond to entirely different treatments.

What is the difference between hyperpigmentation and melasma?
Melasma is one specific type of hyperpigmentation driven by hormonal triggers combined with UV exposure. It presents symmetrically on the face (both cheeks, upper lip, forehead). Hyperpigmentation is the broader term covering any darkening from any cause: acne marks, sun spots, freckles, and others. Melasma requires specific treatment (including hormonal consideration) that is different from the approach for PIH or sun spots.

What causes dark spots after pimples on Indian skin?
When a pimple causes inflammation, melanocytes in the surrounding skin produce excess melanin as part of the healing response. In Indian skin (Fitzpatrick IV-VI), this melanin response is stronger than in lighter skin types, producing a darker, longer-lasting mark. The mark is flat (not raised), which distinguishes it from a true acne scar. Consistent use of niacinamide, azelaic acid, retinoids, and daily SPF speeds fading significantly.

Which is the best treatment for hyperpigmentation in India?
It depends on the type. PIH from acne responds well to niacinamide, azelaic acid, retinoids, and Q-switched laser. Melasma needs triple combination cream or tranexamic acid plus strict SPF and often laser for the dermal component. Solar lentigines respond best to Q-switched or Pico laser. There is no single best treatment because the cause determines the treatment.

Does sunscreen help with hyperpigmentation?
Yes, and without it no other treatment works reliably. UV exposure triggers melanin production. Any pigmentation you fade with a topical or laser will be replaced if you do not use SPF 50 PA+++ daily and reapply every 2-3 hours in sun. SPF is not optional in Indian hyperpigmentation treatment: it is the foundation everything else builds on.

Can hyperpigmentation be cured permanently?
PIH from acne can be fully cleared. Solar lentigines can be effectively removed with laser. Melasma cannot be permanently cured because the underlying hormonal and UV sensitivity remains. It can be well controlled with treatment and maintained with the right skincare routine and sun avoidance, but it often recurs with sun exposure or hormonal changes.

Is hydroquinone safe for Indian skin?
At 2-4% used under dermatologist supervision for 3-4 months, hydroquinone is effective and has a well-established safety record. It should not be used continuously for longer than 4 months, as prolonged use can cause ochronosis (paradoxical darkening) in some individuals. Many OTC skin lightening products in India claim to contain hydroquinone or alternative agents but may actually contain unlabelled steroids, which cause a different set of problems. Prescription hydroquinone from a dermatologist, used as directed, is appropriate for Indian skin.

What is the fastest way to remove dark spots?
Q-switched or Pico laser combined with a topical protocol (niacinamide, azelaic acid, retinoids, Vitamin C, SPF 50 PA++++) produces results faster than topicals alone. For PIH from acne, most patients see significant improvement within 6-12 weeks of a combination approach. For melasma, laser clears visible pigmentation faster but maintenance is required to prevent recurrence.
