So after a run of hideous cold sores Dr Google told me that l-lysine daily tablet helps to prevent the buggers. I’ve just reached the end of my first bottle (60) so about 2 months of taking it - and (touchwood) cold sores are keeping quiet, but also my skin is the best it has ever been - so soft, smooth and firm. Apparently it encourages collagen production.
I thought I would share! It’s cheap and easy (oh but the tablets are like bloody horse tablets - massive.) worth a go if your skin is problematic maybe.
