I am obsessed with Peter Thomas Roths whole water drench HA line. This has been my go-to for hydration for awhile now.
This provides 72 hrs of moisture to the skin, it has a really nice cooling sensation and it feels like your face is immersed in a cloud of water.
I use this mask 3 times a week after my hyaluronic serum but before my treatment serums. You put this on for 3 minutes and rinse off. When I say your skin feels hydrated....it feels hydrated.
