Dark patches and melasma are common and treatable. Learn the classical Vyanga view, why sunscreen is the core treatment, and when a dark patch is a warning.
Pigmentation problems usually mean patches of skin that are darker than the surrounding skin - most often on the face. The commonest pattern is melasma: symmetrical brown patches on the cheeks, forehead or upper lip, driven by sun exposure and hormones. Other causes include marks left after acne or skin injury (post-inflammatory pigmentation), sun spots, and certain medicines. These are harmless in themselves, but any pigmented patch that is new, changing, or irregular should be checked - skin cancer occasionally presents as a dark patch.
Classical Ayurveda describes facial dark patches as Vyanga - painless, thin, dark or bluish-black patches on the face - with Nilika as a closely related entity, and Tvak-vaivarnya (loss of normal skin lustre) tied to disturbed Bhrajaka Pitta, the sub-dosha governing skin tone. These are traditional interpretive frameworks, not exact translations of a modern diagnosis.
These terms explain a traditional model of skin colour. Modern dermatology describes pigmentation through melanin production by skin cells, driven by ultraviolet light, hormones and inflammation.
In the traditional account, Vyanga follows excessive anger (which provokes Pitta), severe grief, overexertion, intense sun and fire exposure, suppression of the natural urge to vomit, and pungent, sour, salty or burning foods that vitiate Pitta and Rakta. These are traditional explanations, not a complete account.
In modern dermatology, melanin overproduction is driven by ultraviolet exposure - the dominant factor - plus hormonal influences (pregnancy, contraceptive pills, hormone therapy), genetics, skin inflammation and injury (acne marks, eczema, waxing), some medicines, and thyroid disease in the case of melasma. Melasma is commoner in women and in medium to darker skin tones. Darker patches after inflammation are commonest in darker skin.
In the traditional account, emotional provocation and sun or fire exposure aggravate Pitta, which vitiates Rakta Dhatu; the disturbed Bhrajaka Pitta then fails to maintain normal skin tone, and dark, painless patches appear on the face. Because the involvement is of Pitta-Rakta at the skin level, classical management combines cooling internal measures with external pastes. This is a traditional explanatory model, not a proven account of melanin biology.
In modern understanding, ultraviolet light and hormonal signals stimulate melanocytes to produce more melanin, which is deposited in the upper and sometimes deeper skin layers. Sun exposure darkens existing patches and undoes treatment - which is why sun protection is the backbone of all pigmentation care.
| Component | Traditional interpretation, not a laboratory diagnosis |
|---|---|
| Dosha | Pitta predominant, with Vata association in Vyanga |
| Dushya | Rasa and Rakta Dhatu; Tvak (skin) |
| Srotas | Raktavaha Srotas |
| Srotodushti | Sanga and Vaivarnya (discoloration), traditional explanatory concepts |
| Agni | Variable in the traditional account |
| Ama | Not central; Pitta-Rakta vitiation dominates the model |
| Adhisthana | Mukha-pradesha (face) and skin |
These are not validated categories for distinguishing melasma from other pigmentation.
Melasma appears as flat, symmetrical brown or grey-brown patches, typically on the cheeks, forehead, bridge of the nose and upper lip, without pain, itch or scaling. Post-inflammatory pigmentation appears as dark marks exactly where acne, eczema or injury occurred. Classical descriptions of Vyanga match well: painless, thin, dark patches on the face.
See a doctor for any pigmented spot that is new in adulthood and enlarging, asymmetrical, irregular-edged, multi-coloured, bleeding or changing - these are warning features of melanoma, which needs urgent assessment. Widespread darkening with fatigue, weight loss or low blood pressure symptoms can indicate an internal illness such as adrenal disease and also needs testing. Distressing but stable pigmentation is a routine dermatology matter, not an emergency.
Modern classification separates melasma, post-inflammatory hyperpigmentation, sun spots (solar lentigines), freckles, and pigmentation from medicines or internal disease - because causes and treatments differ. Melasma is further divided by skin depth (epidermal, dermal, mixed), which affects how well it responds to creams.
The classical tradition distinguishes Vyanga (facial dark patches), Nilika (dark patches more widely), and related spots such as Piplu and Tilakalaka (freckles and moles), guiding traditional care. Traditional pattern labels cannot determine whether a patch is melasma, a mole, or something dangerous; modern examination does that.
Diagnosis is usually visual, sometimes aided by a Wood's lamp or dermatoscope to judge pigment depth and exclude look-alikes. No blood tests are needed for straightforward melasma, though thyroid testing is reasonable in some cases. Any uncertain pigmented lesion is assessed for biopsy, not observed at home with creams.
In the traditional framework, a practitioner assesses constitution, digestion, emotional patterns and skin to plan supportive care. This assessment cannot judge pigment depth or exclude melanoma; modern examination comes first for anything changing or unusual.
Traditional guidance for Pitta-Rakta conditions favours cooling, bitter and sweet foods - pomegranate, raisins, cucumber, leafy greens, ghee and milk - and reducing very pungent, sour, salty and fried items. No food fades pigmentation. A generally balanced diet supports skin health; antioxidant-rich fruit and vegetables are sensible, but diet is not a treatment for melasma.
Sun protection is the single most effective measure in all of pigmentation care: daily broad-spectrum sunscreen (SPF 30 or higher, applied generously and reapplied), hats, and avoiding peak sun. Without it, every other treatment fails. Avoid picking acne, harsh scrubbing, and irritating cosmetic procedures on inflamed skin, which leave dark marks - and be cautious with waxing and threading over melasma-prone areas. The classical caution about sun and fire exposure (Atapa, Agni-sevana) points the same direction.
Modern dermatology treats melasma with prescription combinations (hydroquinone-based or triple-combination creams, used under supervision), azelaic acid, tranexamic acid, and chemical peels or lasers in selected cases - all with real but partial results, and melasma often recurs. A serious warning: unregulated "fairness" and "glow" creams sold in shops and online are frequently adulterated with potent steroids, mercury or excess hydroquinone, which thin the skin, worsen pigmentation and poison the body. Never use an unnamed or unlabelled lightening cream. Classical texts describe Varnya (complexion-restoring) care with Manjistha, Haridra (turmeric), Chandana (sandalwood) and Kumkumadi Taila, applied as lepas (pastes) and oils. Their traditional use does not establish that they treat pigmentation, evidence is limited, and even natural pastes can irritate or cause allergy - patch-test, and discuss any product with your clinician and a qualified Ayurvedic practitioner.
Classical texts describe Mukha-lepa (facial pastes), gentle Abhyanga and, for Pitta-Rakta conditions, internal purification such as Virechana under supervision. These are traditional procedures, not proven pigmentation treatments, and strong procedures are unsuitable for home use. They must not replace sun protection or dermatology assessment of changing lesions.
Post-inflammatory marks usually fade over months with sun protection. Melasma is controllable but tends to recur, especially with sun exposure or hormonal changes; pregnancy-related melasma often improves after delivery. Classical texts regard recent, superficial Vyanga as responsive and deep or long-standing discoloration as slow to shift - matching the modern epidermal-versus-dermal distinction. There is no reliable promise that any cream, paste or herb will clear pigmentation within a fixed period.
Both approaches value cooling moderation and protection from excess sun and heat. The decisive difference is that modern dermatology can classify the pigmentation, exclude danger, and offer assessed treatments - while the classical tradition offers a framework of Pitta-pacifying diet and Varnya skin care. Traditional terms should be presented as a separate framework, with its limits stated. Ayurvedic care must not delay assessment of changing or irregular pigmented lesions, and unregulated lightening creams should be avoided entirely.
The Ayurveda notebook draws on discussions of Vyanga, Nilika and Tvak-vaivarnya among the Kshudra Rogas in Sushruta Samhita (Nidana Sthana 13), Ashtanga Hridaya (Uttara Sthana 31-32), Madhava Nidana and classical Dravyaguna texts. These are background for traditional concepts, not clinical proof of a lightening effect. Exact verse citations and formulation indications should be checked by a qualified Ayurvedic editor before being quoted as direct text.

Marks left by acne often fade over months, especially with sun protection. Melasma tends to persist and recur but can be controlled. New or changing patches should be checked rather than waited out.
Daily broad-spectrum sunscreen. Sun exposure drives nearly all pigmentation and undoes every other treatment.
Unregulated ones are not - they are frequently adulterated with steroids, mercury or excess hydroquinone and can seriously damage skin and health. Use only properly labelled products, ideally discussed with a dermatologist.
Turmeric (Haridra) and sandalwood pastes are classical Varnya remedies and generally gentle, but evidence for lightening pigmentation is limited, and any paste can irritate. Patch-test first.
When it is new and enlarging, asymmetrical, irregular-edged, multi-coloured, or bleeding - get it checked promptly. Those are the warning features of melanoma.
