When your skin barrier is impaired, your skin is less effective at hanging onto water and staying hydrated, exacerbating the appearance of lines, luminosity and causing inflammation. Simple measures come first - cut back on actives and use creamy ceramide rich cleansers that rebuild and hydrate. Next come specialist serums and hydrators that lock water in, like squalane, ceramides, cholesterol, Vitamin B3 and ingredients that act as water magnets such as glycerin and hyaluronic acid. Also bolstering your microbiome enhances your skin's depleted defences. When your skin is made strong, you help it to help itself. Simple!
