How is lichen planus pigmentosus on the face treated?

The face may develop brown or grey patches after inflammation, sometimes with fine bumps, itch, or subtle redness. Colour can deepen with sunlight, heat, rubbing, or a product that causes irritation. A dermatologist first considers whether the process is active and whether another pigment disorder, contact reaction, or medication effect could look similar. The plan may focus on stopping inflammation rather than chasing colour immediately, because aggressive treatment can irritate the skin and create more uneven tone.

Use a mild cleanser, bland moisturiser, and daily broad sun protection; add shade and a hat when practical. Do not scrub, pick, bleach, or layer strong acids over the patches without clinical guidance. If active inflammation is present, a dermatologist may prescribe a topical corticosteroid for a carefully limited course or select another anti-inflammatory option. The medicine must match facial skin, where overuse can cause harm. See [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) and [Lichen Planus](/conditions/lichen-planus/) for related information.

Contact your clinician if facial patches spread quickly, become raised, painful, scaly, or bleed, or if a new product causes marked burning or swelling. Arrange an examination for colour change near the eyes or lips, and seek urgent help for sudden facial swelling with breathing difficulty. Follow-up matters because treatment may need adjustment as inflammation and pigmentation change at different speeds.

Ask whether your patches are active or mainly residual pigment, which ingredients to avoid, and how long a prescribed facial medicine should be used. Discuss realistic colour goals, sun protection, review timing, and whether a biopsy or specialist opinion would help.
