What value glycolic acid peel should I use for my bikini area?

Hi! I am a 19 year old female with light skin and dark hair, and for years I have suffered from ingrown hairs, lately this has gotten better, and I have very very dark skin and scarring left on my bikini line. It is embarrassing and unsightly. I only wax (never shave) every 3 or so weeks, and I have tried EVERYTHING. I do not want laser therapy for this, so please let me know what % glycolic acid peel I can use for this area that will be safe but also help remove these dark marks. Thank you
