Don’t quit moisturizing because the heat is on. “It is critical to use hydrating ingredients in the summer due to the increased humidity,” says Charmaine Cooper, education manager for Dermalogica Canada. High humidity makes you sweat, which decreases the electrolytes in the body—a key component in skin’s hydration. “If we don’t give skin the water it needs, it can overcompensate by producing more oil,” adds Cooper.
