If your skin is simply parched this season, the First Aid Beauty Hydration Stars ($12) is the equivalent of a tall glass of water. The Ultra Repair Cream offers long-term hydration for face and body, and the Ultra Repair Lip Therapy offers the same to your lips. Both products use colloidal oatmeal (to help calm distressed skin) and shea butter (to protect the skin's barrier from the elements). The tube of cream is small enough to toss in a bag — but there are also two larger versions available ($32-$40). The 6,000 reviews and 150,000 loves at Sephora for it must be onto something.
