Hypopigmentation (Loss of Skin Colour) - Symptoms, Causes & Treatment
Medically reviewed by Dr. Anand S. Urhekar, MD, MD Pathology, Clinical Advisor · Last updated July 2026
A general term for skin that is lighter than a person's normal colour because of reduced melanin production or loss of melanocytes. It has many causes, from post-inflammatory change and tinea versicolor to pityriasis alba, vitiligo and inherited conditions, and identifying which one is present determines treatment.

Quick Answer
Hypopigmentation is skin lighter than your natural tone, caused by reduced melanin. Common causes are post-inflammatory change after eczema or a burn, tinea versicolor, pityriasis alba, and vitiligo. Distinguishing features matter: scaly patches suggest fungal infection, fuzzy borders suggest post-inflammatory change, and sharply demarcated chalk-white patches suggest vitiligo, which needs dermatology assessment.
Symptoms
- Patches lighter than the surrounding skin
- May be off-white or chalk-white depending on cause
- Sometimes fine scale
- Borders may be fuzzy or sharply defined
- More noticeable in richly pigmented skin and after sun exposure
Causes & Risk Factors
- Post-inflammatory hypopigmentation after eczema, psoriasis or burns
- Tinea versicolor (a superficial yeast infection)
- Pityriasis alba in children
- Vitiligo (autoimmune melanocyte loss)
- Potent topical or injected steroids; rarely inherited conditions such as albinism
Treatment & Management
- Diagnosis first — Wood's lamp examination and skin scrapings
- Treating the underlying cause (antifungal, emollients, steroid reduction)
- Topical calcineurin inhibitors for selected inflammatory causes
- Phototherapy for vitiligo and extensive pigment loss
- Daily sun protection to reduce contrast
When to See a Doctor
See a doctor if pale patches are spreading, becoming completely white, appearing around the eyes or mouth, or not recovering after several months — accurate diagnosis changes treatment substantially.
Frequently Asked Questions
Does hypopigmentation always come back?
It depends on the cause. Post-inflammatory hypopigmentation and pityriasis alba usually repigment over months. Vitiligo requires active treatment and may not fully repigment. Tinea versicolor clears with antifungals but colour takes months to even out.
Can sunbathing even out the colour?
No. It darkens the surrounding normal skin more than the affected patch, increasing the contrast, and it adds UV damage. Sun protection is the better strategy.
