You have lots of box cars, hypertrophic scars, hyperpigmentation, icepicks.
No treatment provides 90% improvement, it depends how you heal and sadly for acne scar patients this is not the best or they would not have scars to begin with. 50% is reasonable after many treatment, if you get more great.
You mainly need tca cross, steriod injections to your hypertrophic scars, laser for your hyperpigmentation, and some subcision for your boxcars. RF needling will also help. At home I Want you to dermastamp the borders of the box cars monthly and alternate w/ glycolic peels. Wear sunscreen.
** Please Note I offer to acne scar suffers a "more" "customized" (private) consultation than the above general advice. Analysis, answering questions, ongoing support by Private Messaging. Feel free to message me there. Be patient as I can get over 100+ of the worst acne scar cases to help, it "may" take me up to 48 hours to respond.
Checkout the main scar treatments sub, find the FAQ pinned on top there, goto the bottom, there are Dr's or call around and ask who does cannula subcision or nokor subcision (needle type) to dermatologists and or plastic surgeons, consult a few before you decide who you like, even if you have to pay as treatment is expensive, better like them. Ask how many subcisions they do a month and if they treat your skin type. If they just do laser run they will just blast you and not solve your issue.
