Benzaclin gel is used to treat acne vulgaris, a common skin condition characterized by the formation of pimples, blackheads, and whiteheads on the forehead, jawline, chin, cheeks, neck, chest, and back. It contains a combination of two active ingredients, benzoyl peroxide and clindamycin, which work together to reduce inflammation, kill bacteria that cause acne, and prevent new breakouts from forming. Benzaclin gel is applied topically to the affected area once or twice daily as directed by your doctor. It is important to use Benzaclin as prescribed and to follow your doctor’s instructions carefully to achieve the best results.
