Avene's hydrating mask is a favorite for many. "When I want to do a restorative/uber-hydrating routine, I'll slather it on, allow it to fully absorb over the course of several hours, then do a very thin sleeping pack layer," says lgbtqbbq, who also recommends using the mask on long flights. Apparently, it's designed as a rinse-off mask, but lgbtqbbq explains that since there are "absolutely no irritating cleansing agents" in it, it can be left on.
Reddit user stardewspirit can't get enough of this multi-purpose balm. She says the "super thick face and body balm that contains 4-percent niacinamide" (which happens to help with deep hydration and barrier repair) is great, especially during harsher winter months.
