The LAYERLAB Barrier Boost Serum combines 5% panthenol and 4% niacinamide in a formulation designed to support sensitive skin. Panthenol, also known as provitamin B5, is included to help maintain skin hydration and support the natural barrier function. Niacinamide, a form of vitamin B3, is incorporated to assist with soothing the skin and improving overall texture. This Korean skincare product utilizes niosome technology, a delivery system that encapsulates active ingredients to enhance their stability and penetration into the skin.

The serum has a lightweight, non-greasy texture that absorbs quickly without leaving a sticky residue. It is suitable for daily use on sensitive or irritated skin, as well as for those seeking to strengthen their skin barrier. The formula is free from harsh additives, focusing instead on gentle, effective ingredients. This 50ml (1.69 fl.oz) bottle is intended for consistent application as part of a skincare routine.

The product is best suited for individuals with dry, dehydrated, or reactive skin types, as the panthenol and niacinamide work together to calm redness and improve moisture retention. It can be applied after cleansing and toning, before heavier moisturizers or creams. The niosome panthenol serum is not designed to address severe skin conditions but rather to offer daily support for maintaining a balanced, comfortable complexion. Its affordable pricing reflects an accessible approach to skincare without compromising on ingredient quality.
