Hi this is not scarring but cystic pustular acne. Often in cases like this ematrix rf sublative can help the area improve, laser hair removal can be done if there are ingrown hairs, or q-switch carbon peels putting carbon on for 1.5 hrs and having it lasered off which cleans the pores. Because of how pustular it is the acne you may wish to see if your Dr can put you on Acctuante but review the benefits and the cons of using it. The red or brownish areas are PIE or wounding post acne, it can take up to a year to heal from, vascular laser is highly effective for this.
