On Monday, in our connective tissue lecture, we talked about hyaluronic acid, this incredibly huge glycosaminoglycan (over a million daltons – wow!) that does all kinds of things, including holding up to 1000 times its weight in water.
We talked about how it’s used in dermal fillers like Restylane and Juvederm. And I mentioned that old formulations of topical hyaluronic acid had just plain old huge hyaluronic acid molecules in them (so they just sat on top of the skin and – at most – did a little moisturizing) – but now, there are products that contain several different sizes of hyaluronic acid molecules (some even have HA packed into nanoparticles), so they can actually permeate the skin and add some resiliency. Nice!
So I thought I’d share some information on topical hyaluronic acid products here in case you’re interested.
First, here’s a great overview article on topical hyaluronic acid products from this great website called Into the Gloss. You may already know this, but in case you don’t: the creator of Into the Gloss, Emily Weiss, started a skin care and beauty brand called Glossier several years ago. The products are so good, and so reasonably priced, that they very quickly gathered a cult following – and in 2019, Glossier officially became a unicorn (a business valued at over 1 billion dollars).
Anyway – Glossier has a great hyaluronic acid product called Super Bounce that’s only $29. I was talking with a few students after class and one mentioned The Ordinary’s hyaluronic acid serum which is also really good, and only $13.50 (they have a ton of really high quality products at incredible prices – no idea how they do it!). If you have a favorite, email me, and I’ll post it here! Who knew histology could be so practical?!
