Thank you for your question. Evaluating your skin through photographs is difficult, but from your photos, it looks like you have a combination of inflammatory lesions and comedones. Acne treatments are based on the type of acne and skin type you have. Treatments include oral antibiotics, medicated creams and ointments, Accutane, or cosmetic procedures such as peels, laser treatments, or facials. In my experience, I found a combination therapy of oral antibiotics and topical medications to be effective in treating mild to moderate acne. The dark marks you have look like hyperpigmentation caused by your acne. Treatment options include topical lightening creams, or chemical peels, or laser treatments. The right modality for you depends on your skin type, expectations, patience, downtime, and cost. I highly recommend you consult with a board certified dermatologist to have your skin evaluated and to discuss treatment options that best suit your needs. Take care and good luck.
