Can Keloids Be Softened, Flattened, or Removed with Glycolic Acid?

Typically keloids do not respond favorably to chemical peels and may actually get worse and grow larger due to the irritation from the chemical. I would stay away from trying to treat them with chemical peels. You might want to inquire about vascular laser treatments as they are more effective. I hope this information helps.

Unfortunately, keloids do not respond to or improve with chemical peeling. Rather, I would recommend that you consult with a dermatologist to speak about other treatment options, including shave excision, dermabrasion, laser therapy, or surgical revision for keloid improvement.
This can be followed by steroid injection or radiation to help minimize risk for recurrence, depending on the location and type of keloid. This can be a challenging problem to treat, but there are treatments available... I would not expect improvement with glycolic acid, however.

VERY very very doubtful to achieve any improvement in your keloids by this method. But you can certainly try it. Read other blogs answering this question here on REALSELF.

Keloids are caused by fibroblast bioactivity and cannot be modulated with Glycolic acid.  However, there are other non surgical treatments that have worked very well in patients, including IIT and laser treatment. Surgery90210
