• Got hyaluronic acid filler 1 year ago • Never had cold sore but noticed red patch on lip 2 months ago - it didn't blister up like a cold sore and didn't go away • Yesterday my whole top lip became itchy, red and swollen. Could this be because of the filler? I am scared of necrosis or something. • I've included pic 1 before lip filler, pic 2 after lip filler looking normal, pic 3 a couple of months ago when the redness started, and pic 4 is my lip now. Please help, thank you.
