It takes several weeks for laser results to settle. I recommend following up with your Doctor for after care. I recommend skin care with vitamin c, b5 hydrator, silicone based scar gels with growth factors and enzymatic washes with papaya enzyme. PDT therapy can help calm inflammation. Melasma needs a combination approach to get the best improvement and will need a series of treatments. First and foremost, always wear sunscreen daily. Cosmelan is a “gold standard” leave-on peel that has a high concentration of antioxidants and skin brightening actives that can used safely on all skin types especially skin types that have irregular pigmentation such as African American, hispanic, asian and mixed ethnicities. Its effects are to improve discoloration, hyperpigmentation, melasma, while also helping skin texture, pores, and acne scarring. Cosmelan inhibits tyrosinase, an enzyme in the melanin formation process, the process of your skin tanning. So the end result is a more even skin tone without as many irregularities. Other treatments in our practice, we combine Clear + Brilliant, peels, Microneedling/PRP, Aerolase, and sometimes Erbium Laser (coollaser) to get the best results. See an expert. Best, Dr. Emer
