Buy or DIY: Citrus Facial Scrub

Whenever you use an orange, lemon, lime, or grapefruit, make sure to save the peel, which contains skin-rejuvenating essential oils. 

Citrus does double duty: The acid in the oil helps loosen the dead top layer of skin, and the ground-up peels slough it off.

DIY It

A natural exfoliator from Janice Cox, author of "Natural Beauty at Home."

• 1 Tbsp. dried citrus peel, chopped and finely ground in a food processor
• 1/2 cup plain yogurt
• 1 tsp. pure honey
• 1/4 cup vitamin E oil

Mix the ingredients until well blended and massage on a damp face. Rinse well with warm water and finish with a splash of cold. Though the scrub's nicest when used fresh, you can store leftovers in the refrigerator for up to a week.
