Your skin may start to feel tight even before you notice visible symptoms, like mild flakiness, says Boer Kimball. You need gentle products that hydrate without making your skin feel greasy.

On Your Face, Use:

Kiehl’s Centella Skin-Calming Facial Cleanser, $28.50
Avoid soaps, which strip skin’s natural oils, says Ann Marie Cilmi, director of education and development for Bliss Spa, in New York City. This soap-free cleanser has aloe and chamomile, which are soothing.

Zia Skin Basics Nourishing Crème, $35
