Wheat Oligopeptide

Wheat oligopeptide is a high-quality natural humectant with a moisturizing mechanism different from traditional glycerin-based ingredients, delivering dual effects of active hydration + passive water locking. Its molecular structure contains abundant polar amino and carboxyl functional groups, which can form hydrogen bonds with water molecules, rapidly penetrate into the stratum corneum and replenish intercellular moisture. Meanwhile, the peptide forms a breathable hydrated protective film on the skin surface to reduce transepidermal water evaporation, regulate cutis oil-water balance, and improve skin conditions such as dryness, roughness and flaking.

In practical applications, the peptide is commonly incorporated into toners, moisturizing lotions, face creams, serums and other products at a dosage of 0.5%–2.0%. Clinical test data shows that moisturizing creams containing 1.5% the peptide can increase the moisture content of the skin stratum corneum by more than 30% within 24 hours after use. Its moisturizing durability outperforms ordinary glycerin-formulated products, making the peptide especially suitable for dry autumn and winter seasons, as well as dry cutis and sensitive cutis during seasonal transitions.

In addition, its small-molecule property promotes the skin's absorption of other moisturizing ingredients (such as hyaluronic acid and ceramide) to synergistically enhance the moisturizing effect. The peptide has now become one of the core compound raw materials for high-end moisturizing skin care products.

Damaged cutis barrier is the core problem of sensitive cutis, redness-prone skin and post-medical aesthetic skin, manifested as increased Transepidermal Water Loss (TEWL), redness, stinging, desquamation and other symptoms.

The amino acid composition of the peptide is highly similar to the structure of cutis Natural Moisturizing Factors (NMF). The peptide can simulate NMF functions, promote the proliferation and differentiation of keratinocytes, and accelerate the repair of damaged stratum corneum. Meanwhile, the peptide stimulates fibroblasts to synthesize collagen and elastic fibers, enhances the supporting force of the dermis, restores the integrity of the skin barrier, and reduce cutis damage caused by external irritation.

This characteristic makes the peptide a key raw material for sensitive cutis-specific cutis care products and post-medical aesthetic repair products. The peptide is often compounded with ceramide, squalane, panthenol and other ingredients to prepare repair serums, soothing facial masks, repair lotions and so on.

Clinical test data indicates that continuous use of repair masks containing wheat oligopeptide for 7 days can reduce the transepidermal water loss rate of damaged cutis by 25%–40% and improve the relief efficiency of redness and stinging symptoms by more than 50%. The peptide is applicable to the repair of various barrier-damaged cutis such as hormone-dependent dermatitis, UV sunburn and post-medical aesthetic recovery.

Furthermore, its low allergenicity (gluten allergens removed) reduces the risk of irritation for sensitive skin. Mild and non-irritating, it meets the skin care needs of sensitive skin for simplicity, mildness and repair.

Rich in aromatic amino acid residues such as tyrosine and tryptophan, the peptide acts as a hydrogen donor to directly scavenge reactive oxygen species including superoxide anions and hydroxyl free radicals on the cutis surface, reducing oxidative damage to skin cells and delaying skin aging.

Meanwhile, the peptide elevates the activity of cutis antioxidant enzymes (SOD), promotes glutathione (GSH) synthesis, inhibits oxidative stress, and reduces photoaging and fine line formation induced by external environmental factors such as ultraviolet radiation and pollution.

In addition, the peptide stimulates collagen synthesis, improves cutis elasticity and firmness, and reduces wrinkle formation, achieving dual anti-aging effects of antioxidation + collagen promotion.

In anti-aging products, the peptide is frequently added to anti-aging serums, eye creams, firming face creams and other categories, and produces synergistic effects when combined with vitamin C, retinol, niacinamide and other ingredients.

For instance, anti-aging serums containing the peptide can alleviate UV-induced cutis photoaging and improve dullness and sagging. Long-term use leaves the skin delicate and radiant. When applied in eye creams, the peptide fades dry lines and fine lines around the eyes, relieves eye dryness and dullness, and caters to the anti-aging demands of early aging cutis and mature cutis.

At present, anti-aging cutis care products containing the peptide have become mainstream items in the mid-to-high-end skin care market with continuously rising market recognition.
