There are many reasons that can lead to skin discoloration after a facelift. Inflammation can cause increased blood vessel formation, which can lead to a red or bluish discoloration depending on the level of the vessel and whether they're due to an arterial or venous source.
Other reasons include iron deposits that can happen after bruising, and can leave a dark discoloration. Due to the inflammation, your skin becomes more sensitive and can develop a reactive process that can lead to post inflammatory hyperpigmentation and abnormal skin tanning. Each process can benefit from different treatments.
