Im sorry about how you got those marks, but they can be lightened over time with some topics creams and non invasive treatments.
Q switched lasers, like the new picosecond laser which we use, are effective at breaking down the excessive pigment buildup left after an injury (known as post-inflammatory hyperpigmentation [PIH]). This can be combined with gentle chemical peels to speed up the process. This might typically take 4 to 5 session, with each session 2 to 4 weeks apart. The sessions of laser for that size of pigmentation can go for between 200-400, depending on the clinic and type of laser used.
You could, on top of that, use topical retins or bleaching creams to compliment the above procedures.
I hope this helps.
