Other than that, I think this is a great serum. What I like about this serum compared to the Hydra B5 gels that I’ve tried is that this also contains ceramides, whereas the others don’t. If Paula’s Choice sells this in bulk packaging, say 60ml, I’d be stocking up on it like crazy. If you haven’t tried hyaluronic acid serums before, I highly recommend giving them a go. Try layering them with your favourite serum. I’m pretty darn sure you’ll see a difference to your skin, especially when the air is very cold and/or dry.
