Here's another cult favorite: This Vaseline-like balm has earned quite the devoted following over the years. "I have no idea why it's magical, but it SO IS!" gushes ThePlickets, who goes on to say, "I use it for everything (lips, cuts, scrapes, ingrown hairs, burns) and it'll probably last me 6 months a tube."
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.
