Complexion Perfection: Fight Acne and Hide Pimples Like a Pro

Pimple Problem: Shiny Skin by Lunchtime

Clear Fix: Oil levels spike at 11 a.m. every day, explains Laura Goodman, a senior scientist for Procter & Gamble in Cincinnati. Shine may be worse if you're in your 30s, when "oil-pumping hormones peak," Goodman says. Premakeup, apply a clay mask or mix a dollop with your face wash, says Jessica Liebeskind, a New York City makeup artist. Clay clarifies pores and reduces oil production.
