Cool boutique makeup lines that improve the skin but don’t break the bank are hard to find. At one end of the scale, foundation runs up to $30 from Sephora and Henri Bendel (and that’s without dual UV protection or acne treatment). At the other, generic brands cost less than $10 at the local drugstore. Aiming for the best of both worlds is the new e.l.f. (eyes, lips, face) line from Scott Borba, the man behind Hard Candy and Neutrogena Men: All twelve products, from the acne-preventing Clarifying Pressed Powder to the Hypershine Gloss, are $1 each at the chic clothing boutique Cantaloup (1036 Lexington Avenue, at 74th Street; 212-249-3566). No more secret trips to CVS for backup makeup.
