6 weeks post beard transplant - skin redness / discolouration. I don't have access to my surgeon so need answers here (Photo)

Its been exact 6 weeks since I had FUE beard transplant with 1500 grafts. Loss about 50% hair in shedding process (rest survived) and didnt expose myself to sunlight much in the first 5 weeks. After that went carefree to some extent and started walking in direct sun for like 5 mins at a time 2-3 times a day (not purposely but had to) and now I see few grafts less and slight discolouration / redness as seen in the pic. Pls help me fix this as I am very consious about this and tell me what is it.
