Keloid scars are treated differently altogether. Keloids can often grow for months and even years and can often be painful and tender. They are resistant to treatment so they must be handled properly and with care. There are different treatments available for keloids such as cortisone injections, cryosurgery which uses liquid nitrogen to freeze-dry the scar, as well as laser treatment that can help the keloid look flatter. Ultimately, surgical excision can be practiced on a keloid, with the risk of it re-growing, but this procedure can be done in conjunction with others such as laser in order to increase the effectiveness of treatment.
If you have suffered from acne that has left you with unwanted acne scars, please consult your dermatologist to see which acne scar treatment is the best option for you.
