How to fade FUE hair transplant recipient site skin discoloration? (Photo)

I had FUE 4 weeks ago of 2000 grafts. Eight Hundred grafts to hairline and 1200 to crown. Scabs fell off day 10. Recipient site is particularly noticeable. My skin scars easily. Is it wise to use skin fade creams? Is there anything I can do to fade the discolouration? I have a crucial event to attend in 4 weeks time. Will any products with ingredients such as azelaic acid, kojic acid or hydroquinone adversely affect the grafts or the pigment of grafts? Are there any product recommendations ?
