"I tend to alternate my masks a lot, depending on what the season is and how much time I have and what my skin needs," says Gucci. Cooler days call for extra nourishment, so she's already taking pre-emptive steps against the dryness, blotchiness, inflammation and potential rosacea flare-ups that come with fall. On today's masking agenda: May Lindstrom's lush raw honey, white clay, silver, and organic macadamia nut oil blend, which gently dissolves dull skin with natural enzymes as it repairs. (Bonus: "It smells so delicious.")  Just one ten-minute treatment session makes her skin feel "calmer, tighter, brighter" and look visibly less red.

And that's just the tip of the face masking iceberg:  As a professional makeup artist, Gucci tests hundreds of formulas in the interest of finding those that are the most effective to soothe, prep, and transform the complexions of her model and actress clientele—not to mention her own. From the most potent Japanese plumping elixir to an intensive overnight hydration boost and a top dermatologist's pore detoxifying charcoal fix, here are the 5 face masks she swears by for good skin.
