"We use the Hydro Boost Hydrogel Mask by Neutrogena both for our patients in-office and at home for gentle hydration during the winter months. It's lightweight yet still very hydrating," he says. Formulated with hyaluronic acid, this hydrogel mask can be used after cleansing but before your serums. You can leave it on for up to 30 minutes for a deep hydration treatment.
