Grey color skin after high SMAS, forehead lift, neck lift, and lower eye bags removal, 22.5 days post op. Advice? (photos)

It simply looks like you have had extensive bruising which is slow to resolve. Although uncommon it can occur after multiple combined procedures. Best just to wait for it to resolve and keep in touch with your surgeon.

It’s not unusual to have bruising for up to a few weeks after facelift surgery. Sounds like you had multiple procedures done. I would just be patient and await further improvement. From the photographs you look like you’re making progress. Follow up with a local surgeon if you’re concerned about something specific. I wish you the best.
