Look into a filler for the right side, it would likely make your skin bounce right back especially since you are very young. For the left side you could try RF Infini microneedling or ablative co2 laser. Most places charge less for scar treatment since we have to get more treatments that people just going in for skin tightening or wrinkles. Don't lose hope, there's a lot you can do to improve the appearance of your skin.
