Want to know the secret to a natural-looking foundation application? It's all about the sponge. And The Perfectionist Makeup Sponge ($12) from Sephora is much more sophisticated than the triangle applicators found in the drugstore aisles. The dual-ended design is made to fit in the tiniest of crevices (like around the nose) that brushes and your fingers miss. For an airbrushed finish, try applying product while the sponge is damp. That way, your foundation will be absorbed into the skin, making it feel like you barely have any makeup on at all. Finally, the brush vs. fingers vs. sponge debate is settled.
