VITALICIA Barrier Serum is a lightweight, silky serum in the Barrier routine for dryness and moisture-barrier support. Its ingredient list includes squalane, beta-glucan, allantoin and ceramides.

Apply VITALICIA Barrier Serum after cleansing and any toner or essence, then follow with moisturizer. A serum is a concentrated leave-on step, not a replacement for every other step. In the morning, finish with sunscreen; introduce new products individually so you can identify irritation.

No. Barrier Serum offers a lighter layer with squalane, beta-glucan and ceramides, while Barrier Cream provides a richer cream texture with shea butter. You can use serum before cream when your skin needs that routine; avoid adding layers simply to use more product.
