Mary Tkach's Tips for Healthy Beauty
•Delve into the origins of the beauty products you choose.
Tkach's love of particular products is closely tied to the relationships she's formed: "For the company and for me personally, I can't help but care deeply about the indigenous people once I've met them." In her shower, Tkach uses Aveda Shampure Shampoo ($9; aveda.com) with its blend of aromatherapy essences. "I love the aroma, which is a mix of lavender and orange, but I choose this product because it contains babassu and I think about the people I've met in Brazil whenever I use it," she says.
• Surround yourself with the friends and people in your life who make you happy.
Being happy radiates outward and can make you more beautiful, says Tkach.
