Causes:
- Cutaneous inflammation (Dermatitis, acne vulgaris, cellulitis, tinea versicolour)
- Cutaneous injury
- Cutaneou procedure
PIH
- Pharmacological
Topical Corticosteroids
- Reduce inflammation, help accelerate re-pigmentation
Topical Calcineurin Inhibitors
- Reduce inflammation, help accelerate re-pigmentation
- Can be used on more sensitive areas
Topical Antifungals
- Used for tinea versicolour infection
- Topical can take weeks to months (Ketoconazole 2%)
- Oral can be used for short duration or pulse dosing (Itraconazole, Fluconazole)
