Dremz Ultra cream, containing ingredients like kojic acid, vitamin C, and niacinamide, is typically used for 2-3 months to address post-inflammatory hyperpigmentation (PIH); using it for an extended period may lead to skin irritation, dryness, or increased sensitivity; to avoid rebound hyperpigmentation, gradual tapering of the cream is recommended when stopping, such as reducing frequency or switching to a maintenance product, and side effects from sudden cessation are unlikely, but may include mild skin irritation or recurrence of PIH.
