I would use Ematrix RF, Clear and Brilliant laser, and Melarase AM and Melarase PM with a mild exfoliant.
You first need to heal the acne and prevent future breakouts before you attempt to treat the acne scars. Please consult a board certified dermatologist. You may need Accutane to treat this acne and then lasers and peels to remove the scars. Best, Dr. Green

Dark spots from acne is usually the result of active inflammation or post-inflammatory hyperpigmentation where the melanin pigments in your skin accumulate in those particular areas. There are multiple ways to improve the uneven skin tone from the acne but the key is to first get the acne under control by topical or oral therapy. Hyperpigmentation often improves on its own after several months to a year while avoiding sun exposure or wearing sunscreen. Treatments such as peels, lasers, or Intense Pulsed Light (IPL) therapy can further improve the irregular pigmentation depending on your skin type. Finally, improving the skin texture and reducing the pitting from the scars will also help lessen the shadowing and appearance of the scars. This can be done through microneedling, radiofrequency, fillers or a combination of the three.
