OAT Peptide is often referred to as oat protein peptide,oat oligopeptide, Oat Protein Peptide,Oatpeptides, It is a type of active peptide product obtained by cutting large molecular proteins into small peptide segments from oat seed proteins (mainly including oat globulin avenin and oat gluten gluten) through enzymatic hydrolysis or microbial fermentation techniques. From a chemical perspective, a peptide is a compound formed by dehydration condensation of two or more amino acids through peptide bonds (- CO-NH -).

It is rich in branched chain amino acids, glutathione, and various bioactive fragments, and has high water solubility, high absorption rate, low allergenicity, and natural safety.
Skin barrier repair and effective moisturizing use: strengthens the stratum corneum, locks in and stores water, improves dryness and sensitivity
The most core and fundamental skin use of this substance is to repair the skin barrier and provide strong moisturization. By supplementing the nutrition of the stratum corneum, promoting lipid synthesis, enhancing tight junctions, and improving water locking ability, it can fundamentally improve skin dryness, flaking, roughness, sensitivity, itching, and other problems. It is particularly suitable for dry, sensitive, barrier damaged, and hormone dependent dermatitis populations, and is a natural and gentle barrier repair moisturizing ingredient.
Stratum corneum nutrition supplement: Small molecule peptides directly penetrate the stratum corneum, supplement amino acids, promote the proliferation and differentiation of keratinocytes, accelerate stratum corneum repair, and enhance skin toughness and integrity.
Lipid barrier enhancement: activates ceramides, cholesterol, and free fatty acid synthase, increases skin lipid content by 30-50%, repairs lipid barriers, and reduces transcutaneous water loss (TEWL).
Tight junction repair: Upregulate the expression of occludin, claudin-1, and ZO-1 tight junction proteins by 2-3 times, repair intercellular connections in keratinocytes, reduce external stimulus penetration, and enhance barrier defense.
Water locking and storage enhancement: A large number of hydrophilic groups (hydroxyl, amino) in the molecule combine with water molecules to form a moisturizing water film, increasing the water locking ability by 40-60%, providing long-lasting hydration and relieving dryness.
Water cycle promotion: enhances the hydration ability of the stratum corneum, promotes uniform distribution of water on the surface of the skin, improves dryness and roughness, and enhances skin softness.
Improvement of dry skin: TEWL is reduced by 40-60%, dryness and dandruff relief rate is 80%, skin softness is increased by 50%, long-lasting moisturizing, bidding farewell to dryness and tightness.
Sensitive muscle repair: The barrier function recovery rate is 70%, and the tolerance to external stimuli (cold, heat, ultraviolet radiation, chemicals) is improved. Sensitive redness and itching are significantly reduced.
Barrier damaged muscle repair: Hormone dependent dermatitis, excessive cleaning, and medical beauty can shorten the barrier damage repair cycle by 50%, relieve redness, swelling, and pain, and restore a healthy barrier.
Seasonal/Dry Environment Protection: Enhance skin adaptability, reduce dryness, peeling, and itching during seasonal changes, and maintain skin hydration and stability.
No sensitization risk: natural plant source, hypoallergenic, safe for use by sensitive muscles and infants, without side effects of essence, alcohol and hormone.

Frequently Asked Questions
Do oats have peptides?
+
-
Highlights. In vitro digestion by pepsin and trypsin in simulated gut conditions was effective to generate small peptides from oat protein. Oat peptides showed capacity to inhibit DPP4 and HMGCR, promoting satiety and lowering cholesterol.
What do oat peptide and hyaluronic acid do?
+
-
Peptides and hyaluronic acid are two powerhouse ingredients found in many skincare routines, but they serve distinct roles. While hyaluronic acid is a hydration hero, drawing in moisture for plumper, dewier skin, peptides work at a deeper level to support collagen production and skin repair.
What foods have high peptides?
+
-
The most widely used animal proteins are from eggs, milk (casein and whey), and meat proteins. Bioactive peptides from plant sources are typically from soy, oat, pulses (chickpea, beans, peas, and lentils), canola, wheat, flaxseed, and hemp seed.
Do oats produce collagen?
+
-
Oatmeal also helps boost collagen production, improves your skin complexion, and reduces skin inflammation. You can use it in your bath, use it to make a paste for a face mask, or use it as a gentle cleanser.
