Why you need it: 

First Aid Beauty Ultra Repair BarriAIR Cream is a light-as-air face moisturizer that contains lipids that bio-mimic the natural composition of the skin barrier, helping to fortify it and maintain its healthy state. It works to strengthen the skin barrier, balance and provide adaptable hydration for combination, normal and dry skin types.

Your skin barrier is a protective outer layer that helps keep the good things in, like hydration and lipids and the bad things out, like pollution, irritants, allergens and bacteria. The skin barrier can become compromised by aggressive exfoliation, harsh products or even washing your face too often.
