Is Vitamin C Effective in Curing Post Laser Hyperpigmentation Permanently?

Thank you for your question. Curing and permanently are words I use very carefully.  I think the odds of Vitamin C curing the pigmentation problem is very slim to zero.  The hydroquinone containing products will help, but sunscreen compliance and sun avoidance is critical to the success. She will likely require maintenance therapy for her condition.  I suggest seeking a consultation with a board certified dermatologist or plastic surgeon for safest and best results which will likely require a combination and a series of treatments. I hope this helps.

Vitamin C alone can help improve post inflammatory hyperpigmentation, but is rarely enough as sole therapy.  In my practice, I recommend a regimen of MelaPads twice daily, Melarase AM, and Melarase PM.  It will take some time, but most cases will improve dramatically.
