Really interesting article, thanks for posting. Why is it 'back up', was there some sort of controversy? Sorry if I missed this. It's inspired me to cut out HA temporarily and see what happens, since I have some of the sensitivity and dryness issues mentioned.
ETA: I just thought, this is especially interesting considering the amount of times I've seen Sali tell people they can't possibly be sensitive to HA because it's not an exfoliating acid - and I believed her! I wonder if her next move is "I've always said HA is snake oil, and prefer cosseting ingredients like squalene..."
I don't get on with Clarins, but why does every other person but me find amazing beauty stuff in TK Maxx? I love TK Maxx, but never find anything like the bargains that other people find there. It's always Nars single eyeshadows in weird shades at best. Do they only send certain brands out to certain branches or something?
