Hydrolyzed Oats

Hydrolyzed oats are oat proteins that have been broken down into smaller molecular fragments through hydrolysis. This process reduces the size of the protein chains, allowing them to penetrate the skin more effectively and dissolve readily in formulations. The ingredient is derived from the common oat grain (Avena sativa) and has been used in skincare for decades.In cosmetic formulations, hydrolyzed oats function primarily as a skin conditioning agent. They form a light film on the skin surface and can help bind water to the outer layers, contributing to smoother texture and improved hydrat…

When applied topically, hydrolyzed oats settle onto the skin surface and form a thin occlusive layer. This layer reduces transepidermal water loss (TEWL), meaning less moisture evaporates from your skin. The breakdown of oat proteins into smaller fragments allows them to interact with skin cells more directly than whole proteins.Additionally, oats contain compounds such as beta-glucans and avenanthramides, which are retained even after hydrolysis. These are thought to contribute mild anti-inflammatory effects that may help ease redness and sensitivity, though the overall soothing benefit is…

Hydrolyzed oats work well in both rinse-off and leave-on products. In serums and moisturisers, they layer effectively with other hydrating ingredients such as glycerin or hyaluronic acid. For best results, apply to damp skin to allow the hydrating ingredients to lock in moisture. There is no need to avoid combining it with active ingredients, though it may slightly dilute the efficacy of very potent treatments due to the occlusive nature of the film it creates.

Hydrolyzed oats are generally well-tolerated across skin types. People with oat allergies or sensitivities should avoid products containing this ingredient.
