The 29-year-old Revlon spokesmodel dished to our friends over at BellaSugar that while anti-aging products are definitely on her mind she's a bit of a "'fraidy cat when it comes to anything really aggressive."
"So at this point I'm pretty much [doing] sunscreen, hats, and moisturizing," says Biel.
What exactly makes up the "A-Team" actress' beauty arsenal? Read on for a sneak peek inside!
Dove soap: "One piece of advice was from my friend's beautiful French mother, who literally only ever washed her face with Dove soap and water and she has the most beautiful skin. And I'm looking at her going, 'Have I been messing this up my whole life. . . buying all these beautiful products and I just needed Dove soap - what?!' So I've heard that bit of beauty advice, and then of course - sleep, water, hydrate!"
Gray shadow: "A gray color works for anybody's eyebrows. And it doesn't turn your eyebrows orange. . . I was tipped off by a makeup artist that gray works for blonds, for brunettes, for redheads."
Revlon, of course: "I use the Grow Luscious [mascara]. And I use the eye shadow palettes, which I love - the natural palette. You can layer the colors on top of each other so you can go from day to night really easily. Also, the ColorBurst lip glosses I love. There's a color in there called Peach Petal, which is a beautiful natural color for the day. I usually prefer more of a natural color on the lips."
Essential Oils: "Oils I think have been really important for my beauty routine. I eat a lot of coconut oil a lot of coconut butter. [I also like] fish oils for omega-3. I think it's important for a beauty routine."
