PIGMENTATION DISORDERS

OVERVIEW

Pigmentation disorders affect the color of the skin, producing areas that appear darker, lighter, or uneven compared with surrounding skin. These changes result from alterations in melanin production, distribution, or loss.

Pigmentary conditions are common and affect patients of all ages and skin types. While many are benign, accurate diagnosis is important because similar changes in skin color can result from very different underlying processes.

Pigmentation changes are frequently perceived as cosmetic concerns, but they may reflect inflammation, hormonal influences, autoimmune disease, infection, medication effects, skin injury, or cumulative sun exposure.

COMMON PIGMENTATION DISORDERS

Common pigmentary conditions include:

Post-Inflammatory Hyperpigmentation (PIH)
Darkening that develops after inflammation or injury, including acne, eczema, irritation, trauma, or skin procedures.
Post-Inflammatory Hypopigmentation
Lightening that develops following inflammation or injury and may persist after the original skin condition has resolved.
Melasma
Acquired brown or gray-brown facial pigmentation associated with hormonal influences, ultraviolet and visible-light exposure, and individual predisposition.
Vitiligo
An acquired disorder involving loss of melanocytes, producing well-defined areas of depigmented skin.
Solar Lentigines & Ephelides
Pigmented macules associated with sun exposure and genetic characteristics, including sun or age spots and freckles.
Tinea Versicolor (Pityriasis Versicolor)
A superficial yeast infection producing lighter, darker, or pinkish patches, often with fine scaling on the trunk and upper body.
Pityriasis Alba
Light, mildly scaly patches most commonly involving the face and frequently associated with dry or eczematous skin, particularly in children and adolescents.
Medication- and Chemical-Induced Pigment Changes
Hyperpigmentation or hypopigmentation associated with certain medications, topical products, chemicals, or repeated skin exposure.
Pigment Changes Associated With Chronic Inflammation
Persistent darkening or lightening that can accompany chronic dermatitis and other inflammatory skin disorders.

WHY MEDICAL EVALUATION MATTERS

Different pigmentary disorders can have very similar appearances despite completely different causes.

Pigmentation may be influenced by:

Sun and visible-light exposure
Previous or ongoing inflammation
Hormonal factors
Autoimmune processes
Infection
Medications or topical products
Previous skin injury or procedures

Accurate diagnosis is particularly important before beginning lightening treatments, chemical exfoliation, laser treatment, or other procedures, because treatment appropriate for one pigmentary condition may be ineffective or aggravate another.

MANAGEMENT CONSIDERATIONS

Management is based on the diagnosis, depth and type of pigment alteration, skin type, underlying cause, and clinical history.

Treatment may include:

Control of underlying inflammation or skin disease
Modification of contributing medications or topical products
Sun and visible-light protection
Prescription topical therapy
Treatment of an underlying infection
Procedural or laser treatment for appropriate pigmentary conditions

Additional inflammation can worsen pigmentation, particularly in patients prone to post-inflammatory hyperpigmentation. Establishing the diagnosis before aggressive topical or procedural treatment is therefore important.

Evaluate Pigment Changes

Persistent, new, or unexplained changes in skin pigmentation can be evaluated to determine the type of pigment alteration, underlying cause, and appropriate management.
