Key Summary Points
*A tentative new designation of a ‘‘postinflammatory papule (PIP)’’ for acne vulgaris is proposed
*PIP is defined as brown and dark-brown papules that form from red papules and pustules, resulting in postinflammatory hyperpigmentation (PIH) and scarring
*We define PIP as a transitional eruption between red papules, pustules, and postinflammatory hyperpigmentation (PIH)
*To the best of our knowledge, the concept of PIP has not been described
*We recommend topical benzoyl peroxide (BPO)/adapalene as a treatment for PIP to prevent the formation of atrophic scars
*Further investigation of histopathological findings in PIP is necessary to confirm whether inflammation still exists
