Oat peptides have multiple effects in skin care, and their small molecular structure and bioactive ingredients can penetrate deep into the skin to exert their effects. The following are the specific functions and principles:
1、 Hydrating and moisturizing, strengthening the skin barrier
Efficient water locking mechanism: β – glucan in oat peptides can adsorb 500 times its own weight of water, forming a three-dimensional network moisturizing film on the skin surface to reduce water evaporation; At the same time, it can promote the expression of aquaporin 3 (AQP3) in the stratum corneum of the skin, enhance the skin’s water absorption capacity, and alleviate dryness and flaking problems.
Barrier repair function: Oatamide has a similar lipid structure to the skin and can penetrate into the stratum corneum to supplement missing fatty acids and ceramides, repair damaged barriers, improve symptoms such as redness and stinging in sensitive muscles, and increase the skin’s water locking ability by about 2 times.
2、 Anti inflammatory and soothing, improving sensitivity and inflammation issues
Inhibition of pro-inflammatory factors: Polyphenols and oat amides in oat peptides can inhibit the release of pro-inflammatory factors such as IL-6 and TNF – α, alleviate skin inflammation, and have a relieving effect on eczema, rosacea, allergic dermatitis, etc.
Reduce vascular permeability: By inhibiting histamine release, reduce skin redness and swelling. For example, in post sun repair products, oat peptides can quickly alleviate skin inflammation and burning caused by ultraviolet radiation.
3、 Antioxidant and anti-aging, delaying skin aging
Clearing free radicals: Components such as glutathione and anthracycline can neutralize free radicals generated by factors such as ultraviolet radiation and pollution, reduce oxidative damage to collagen and elastin, and delay aging phenomena such as wrinkles and sagging.
Promoting collagen synthesis: Oat peptides can activate fibroblast activity, promote the synthesis of type I collagen and elastin, while inhibiting the degradation of collagen by matrix metalloproteinase (MMP-1), increasing skin elasticity by about 30% and reducing fine line formation.
4、 Whitening and brightening the skin, improving pigmentation
Inhibition of tyrosinase activity: Certain peptide components in oat peptides can competitively bind to tyrosinase active sites, reducing melanin synthesis while promoting stratum corneum metabolism, accelerating the shedding of generated melanin, and improving dullness and pigmentation.
Regulating post inflammatory pigmentation: reducing abnormal activity of melanocytes caused by inflammation through anti-inflammatory effects, and preventing the formation of acne scars and post inflammatory pigmentation (PIH).
5、 Control oil and eliminate acne, balance skin condition
Regulating sebum secretion: For oily skin, oat peptides can reduce sebum secretion by regulating the activity of 5 α – reductase in sebaceous gland cells. At the same time, the moisturizing effect of β – glucan can prevent compensatory oil production caused by skin dehydration.
Inhibition of Propionibacterium acnes: Its antimicrobial peptide components have a certain inhibitory effect on Propionibacterium acnes, combined with anti-inflammatory properties, which can improve the redness and swelling symptoms of mild acne (pimples, papules).
6、 Application scenarios and product forms
Skin care products: commonly used in essence, face cream, facial mask, eye cream and other products, such as sensitive muscle repair products: use the anti-inflammatory and barrier repair functions of oat peptides to alleviate redness sensitivity. Anti aging products: improve wrinkles and sagging through antioxidant and collagen promoting effects.
Moisturizing products: with β – glucan and small molecule peptides as the core, enhance water locking ability.
Medical beauty postoperative care: As a postoperative repair ingredient, it helps reduce inflammation and accelerate wound healing. For example, using dressings containing oat peptides after laser treatment can reduce the risk of pigmentation.
precautions
Oat peptides have high safety and are suitable for various skin types, including sensitive skin and pregnant women. However, a very small number of people may be allergic to oat ingredients, and it is recommended to undergo skin testing first.
Its skincare effect needs to be combined with formula design (such as compounding with ingredients such as hyaluronic acid and ceramide), and the effect of a single ingredient is limited, requiring long-term use to show significant results.
In summary, oat peptides have a comprehensive effect on the skin through multiple mechanisms such as moisturizing, anti-inflammatory, antioxidant, and anti-aging, from basic care to problem improvement. They are widely used in sensitive skin repair, anti-aging, and moisturizing fields.
