LAYERLAB Barrier Boost Serum combines 5% panthenol and 4% niacinamide in a niosome delivery system designed to support sensitive skin. Panthenol, also known as provitamin B5, is included at a concentration that helps maintain skin hydration and supports the skin barrier’s natural recovery process. Niacinamide at 4% contributes to improved skin texture and may help reduce the appearance of redness and uneven tone, making this serum suitable for those with easily irritated or reactive skin.

The niosome encapsulation technology is used to help protect the active ingredients and potentially enhance their delivery into the skin. This serum has a lightweight, water‑like texture that absorbs quickly without leaving a sticky or heavy residue. It can be applied after cleansing and before moisturizer, as part of a simple daily routine. The formula is free from common irritants such as artificial fragrances and essential oils, aligning with a gentle approach to skincare.

This product is sized at 30 ml (1.01 fl. oz.), which allows for convenient travel or daily use. It is particularly appropriate for individuals who are looking for a soothing serum that focuses on barrier support and soothing properties without relying on strong active acids or retinoids. The non‑greasy finish makes it suitable for combination to oily skin types as well as dry skin that requires added hydration without heaviness. As with any skincare product, patch testing is recommended to ensure individual compatibility. The serum is manufactured by LAYERLAB, a Korean brand that emphasizes functional formulas for sensitive skin.
