This hydrating barrier serum from Experiment is formulated with 30% glycerin, polyglutamic acid, and prickly pear extract to deliver concentrated moisture to the skin. Glycerin acts as a humectant that draws water into the outer layers of the skin, while polyglutamic acid helps retain hydration for longer periods compared to hyaluronic acid alone. Prickly pear provides additional moisture support along with antioxidants that help protect the skin from environmental stress.

The serum is designed to reinforce the skin’s natural barrier function, making it suitable for those who experience dryness or dehydration. It aims to leave the skin feeling plump and looking dewy without a greasy residue. The lightweight, water-like texture absorbs quickly and layers well under moisturizers or makeup.

This product is intended for all skin types, including sensitive and oily complexions, as it does not contain common irritants like fragrance, essential oils, or drying alcohols. The 1.35 fl oz bottle provides a concentrated formula that can be used day or night. A few drops applied to damp skin after cleansing help to lock in moisture and improve overall skin softness and smoothness.

The formula focuses on delivering intensive hydration through a simple yet effective combination of key humectants and botanical extracts. It does not rely on silicones, parabens, or sulfates. By supporting the skin’s moisture barrier, the serum helps maintain a healthy-looking complexion without clogging pores or causing irritation.

Regular use can assist in reducing the appearance of fine lines caused by dryness and promote a more even skin texture. It is particularly suited for environments that strip moisture from the skin, such as air-conditioned spaces or cold weather. The serum can also be mixed with other treatments to boost hydration levels during a skincare routine.
