The Frosty, Nordic Blue Lagoon

With all due respect to Brooke Shields and Christopher Atkins, the true Blue Lagoon is a decidedly un-tropical place. Though a paradise, in its own way.

I visited Iceland last weekend, literally, returning with the expected jet lag but weirdly, no dry skin, which I usually get after a single airplane flight—and this weekend included two.

The magic—and the reason I found myself in the middle of a barren lava field without a tree for miles—is the Blue Lagoon spa. Natural, geothermal hot springs bubble up from the earth, creating the ultimate Jacuzzi. The bottom is a pleasingly mushy mud made of healing silica, minerals, and algae. A few hours of soaking and you're moisturized, glowing, and totally relaxed. You're also totally inoculated against the usual airplane dry skin.

To keep my new, moisture-rich complexion going, I brought home the Silica Mud Mask—the same amazing goop that's in the lagoon, bottled. I slather the super-thick, clear gel all over my face when I'm in the shower—it pulls in hydration from the steam. (You can also use it to cure breakouts by letting it dry into a white cast and working its absorbent magic.) Order it internationally on their website (and I'll let you know when it's up on Saks.com).
