3 Signs Your Skin Is Unbalanced — and What to Do About It

When we say dull, we're referring to skin that's lost its vibrancy and "glow factor." Sallow refers to skin that leans a bit yellow or brown instead of its true color. Sometimes these two go hand in hand, but other times you may experience only one or the other.

"A lack of nutrients to feed the skin, specifically lipids, which support skin structure, contribute to the dull, sallow look," Shamban says. "Lack of sleep can play its part too. Solid, sound sleep stops the body from producing excess cortisol which can cause inflammation getting skin out of balance. Long periods of rest help oxygenation and blood flow, so being sleep deprived can also contribute to a more sallow, dull complexion."
