Hello, Scar treatment of acne depends on the type & the depth of the scar. Also the overall treatment depends on your skin type and color. since you have already tried microdermabrasion and peeling , the other options are scar surgeries like subcision, microneedle therapy, PRP therapy. If cost is no issue, and depending on availabilty , fractional ablative lasers or MNRF treatment are also good treatment options. If done correctly, the modalities are safe and give good results. Though the visible results start appearing after about 3-6 months, treatment for scar can take anywhere between 1-2 yrs for you to see good results. You may continue Kojic cream at night and a good sunscreen with SPF 30 & above daily in morning and afternoon is an absolute must to prevent darkening along with other sun protective measures like avoiding direct sunlight between 10-4 and using hats, stoles, umbrellas etc when out in the sun. creams such as bright night, bright day, melanorm mc, melanorm ms are strictly prescription medicines and should be used as per Dr s advice only.
