Post‑Laser Care and Prevention of Post‑Inflammatory Hyperpigmentation

Sun Protection Measures

Daily application of a broad‑spectrum sunscreen with SPF 30 or higher to all treated areas is mandatory to reduce the risk of post‑inflammatory hyperpigmentation (PIH) after laser therapy. 1

After laser exposure, the treated skin should be cooled and gently cleansed to minimize thermal injury and promote comfort. 3

Laser treatment must be avoided on skin that has active inflammation or infection; proceeding under such conditions markedly increases the likelihood of PIH. 4
Concurrent use of harsh topical agents or aggressive procedures that can provoke additional inflammation should be discontinued before laser sessions to lower PIH risk. 2
Baseline skin inflammation should be addressed (e.g., with appropriate anti‑inflammatory preparation) prior to laser application; failure to do so is associated with a higher incidence of PIH. 2

Low‑ to moderate‑potency topical corticosteroids may be prescribed after laser treatment if residual inflammation is observed, but they should be used judiciously to avoid overt suppression of normal healing. 2
