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 SerumMost unique product: U Beauty The BARRIER Bioactive Face MistEditor's pick: Dieux Instant Angel Lipid-Rich Firming Moisturizer Don't forget to use the code ALLONSALE to score these deals: Sephora Collection: 30% off, Oct. 30-Nov. 9Rouge Members: 20% off, Oct. 30-Nov. 9VIB: 15% off, Nov. 3-9Insider: 10% off, Nov. 3-9 Scroll on for the best barrier-loving deals of the sale!Barrier Support Serums on SaleBeauty of Joseon Calming Barrier SerumMade with green tea and panthenol, this offers calming hydration that lasts through multiple layers.
