With low platelets count 48000 can I have a facelift?

Your platelet count is below 50k. This is too low in my opinion to have cosmetic surgery. You need your hematologist to address your issues and develop a plan to get your low platelet count addressed Earl Stephenson, Jr, MD, DDS, FACS

With a platelet count of 48,000 you would need to see a hematologist before any type of surgery to determine the cause and possible treatment for the low count.  It would not be safe to undergo surgery with the level of your platelets currently.
