I have acne. Should I use clindamycin and tretinoin together or only tretinoin will work?

Thank you for your question. Acne treatments vary on the type of acne present, such as inflammatory lesions (red bumps) or comedones (whiteheads and blackheads). Tretinoin is a topical retinoid that gently exfoliates the skin removing comedones, and topical antibiotics, such as clindamycin, is effective in treating inflammatory lesions. I highly recommend you consult with a board certified dermatologist to have your skin evaluated and to discuss appropriate treatment options that best suit your needs. Take care and good luck.
