10 Makeup Myths You Need to Stop Believing Immediately

This is completely untrue. In fact, if you believe this myth, you are likely contributing to your excess sebum. "Skin will overproduce oil as a response to dryness," remarked Lujan. Cleansing can strip your complexion of its natural oils, and if you don't restore much-needed moisture, your skin will react by getting oilier.

Avoid this by nourishing your skin with lightweight hydration. Lujan suggests looking for skin care formulas that contain hyaluronic acid. "Hyaluronic acid is known to capture a thousand times its weight in water," he said. By drawing water into the skin, you'll keep it soft, healthy, and less greasy. Try an overnight treatment like Fresh Black Tea Firming Overnight Mask ($92). It'll infuse your complexion with deep moisture while you sleep.
