Sephora's Savings Event has officially launched to all shoppers, bringing tiered discounts to everything in your cart.

And we're taking the opportunity to add all of our skin-loving faves to cart, starting with barrier-supporting skincare picks. The skin barrier, a.k.a. the epidermis, is the protective shield that locks in moisture and defends against irritation. But since it's the outermost part of the skin, it can be damaged due to over-exfoliation, active ingredients or seasonal changes.

To help combat that, we've rounded up serums, essences and moisturizers (on-sale) that can soothe the skin and bring back moisture:

• Best value: Beauty of Joseon Calming Barrier Serum
• Most unique product: U Beauty The BARRIER Bioactive Face Mist
• Editor's pick: Dieux Instant Angel Lipid-Rich Firming Moisturizer
