Postinflammatory hypopigmentation treatment: what to know

Inflammation from eczema, a rash, infection, injury or treatment can temporarily reduce pigment production or distribution. The affected skin may look paler rather than completely white, often where the earlier irritation occurred. Fine scaling or a clear border can point toward another cause, such as Tinea Versicolor, while recurrent itch and eczema may suggest Atopic Dermatitis. A clinician can examine the surface and pattern before choosing treatment.

Stop scratching, use a bland moisturiser, and manage the active inflammation with prescribed treatment. Protect the lighter skin from sun because surrounding skin may tan and make the contrast stronger. Do not apply bleaching products. If patches persist after the trigger is controlled, a dermatologist may consider Topical Calcineurin Inhibitors or Excimer Laser Therapy in selected cases. Treatment is guided by the diagnosis, location, extent and whether pigment cells are recovering.

Arrange an assessment if patches spread, recur, become sharply white, involve hair or mucosal skin, or appear without a preceding rash. Seek prompt help for pain, pus, marked redness, swelling or fever. A new area of altered colour should be diagnosed rather than treated solely from a photograph or assumed to be postinflammatory.

Ask what caused the colour change, whether a fungal or inflammatory condition is active, how long observation is reasonable, and what side effects and follow-up apply to each treatment.
