Nonapeptide-1 Skincare

1. Regulating inflammation related signaling pathways
It can regulate inflammation related signals and alleviate tissue damage triggered by inflammation. Derma inflammation is the biggest enemy of repair - inflammatory factors continue to damage newly formed tissue, causing wounds to repeatedly crack and barriers to repeatedly collapse. By downregulating the release of inflammatory factors, the vicious cycle of "inflammation → tissue destruction → more inflammation" is cut off from the source.
2. Reduce UV induced skin redness
UV irradiation not only causes pigmentation, but also triggers acute inflammatory reactions such as redness, swelling, heat, and pain.

The anti-inflammatory properties make it have dual repair value in post sun care: it not only inhibits inflammatory damage, but also soothes redness. Research has shown that it can reduce the redness index of sensitive muscles by 19.3%, which directly proves its clinical efficacy in anti-inflammatory repair.

3. A 'safe pathway' for post inflammatory repair
Traditional restorative ingredients (such as high concentrations of VC and fruit acid) may exacerbate irritation during inflammation. It provides a safe pathway of "anti-inflammatory first, then repair": it does not stimulate already fragile inflamed superficial, but instead creates a stable microenvironment for subsequent repair by inhibiting inflammatory pathways such as NF - κ B. This makes it particularly suitable for use during the "window period of inflammation repair" such as after surgery, laser treatment, and acid brushing.

1. Stimulate skin cell proliferation and differentiation
Nonapeptide-1 skincare can stimulate the proliferation and differentiation of superficial cells. The essence of superficial repair is the shedding of old cells and the replacement of new cells. By activating the proliferation signal of basal layer stem cells, the renewal cycle of keratinocytes is accelerated, allowing damaged superficial to be covered by healthy cells more quickly.
2. Promote re epithelialization
In the superficial injury model, by enhancing the binding force between growth factors and extracellular matrix (ECM), granulation tissue growth and neovascularization are promoted, accelerating the process of re epithelialization.

This mechanism is similar to the repair logic of placental growth factor 2 (PIGF-2) - strengthening the affinity between growth factor and ECM, making repair signals more persistent and efficient.
3. Update cycle optimization
The normal superficial renewal cycle is about 28 days. By promoting cell renewal, this cycle can be optimized to a more efficient state. Clinical observations have shown that using superficial products containing this substance can improve superficial tone uniformity within 14 days, and after 28 days (a complete superficial metabolic cycle), there is a significant improvement in superficial quality. This is not a surface covering, but a cellular level 'renewal acceleration'.

1. Promote collagen synthesis
It can promote the synthesis of collagen, enhance superficial elasticity, and reduce fine lines and wrinkles. This makes it not only a repair ingredient, but also a dual functional peptide of "repair+anti-aging". Adding this ingredient to essence liquid and face cream can achieve the goal of "repairing damaged collagen+preventing collagen loss".
2. Promote the synthesis of elastic fibers
In addition to collagen, it can also protect important fibers (elastic fibers) responsible for superficial elasticity, moisture, and strength, keeping the superficial smooth and preventing the formation of fine lines and roughness. Collagen provides' support ', while elastic fibers provide' resilience '. Only when the two work together can the superficial truly regain its youthful state.

3. Prevent collagen degradation caused by ultraviolet radiation
Ultraviolet radiation is the number one killer of collagen - it activates MMP (matrix metalloproteinases), cutting collagen into fragments. By inhibiting inflammation signals induced by ultraviolet radiation, the activation of MMP is indirectly reduced, preventing further damage to existing collagen. This is a 'defensive repair' - not only repairing the new, but also protecting the old.
4. Promote the synthesis of type I, III, and IV collagen proteins
Research has shown that it can comprehensively promote the synthesis of type I (structural support), type III (soft elasticity), and type IV (basement membrane anchoring) collagen proteins. Type I collagen accounts for over 80% of the dry weight of the derma and is the key to preventing derma sagging; Type III collagen determines the "softness" of the derma; Type IV collagen is the "adhesive" between the epidermis and dermis. Simultaneous promotion of the three types is the true full layer repair.

1. Reverse UVA induced cell damage
Nonapeptide-1 skincare (20 μ M, 3 days) can reverse UVA induced damage in human epidermal melanocytes (HEM cells). UVA has strong penetration and can directly reach the dermis layer, damaging collagen and elastic fibers, which is the main cause of photoaging. By inhibiting the increase of cAMP signaling and oxidative stress triggered by UVA, we can extinguish the fire at the cellular level.

2. Core active ingredients of post sun repair products
Adding it to post sun repair products can effectively reduce post sun redness and accelerate derma tone recovery.

Its dual mechanism of "anti-inflammatory+repair" enables post sun care to no longer be limited to soothing, but to simultaneously address the two major issues of "sunburn (inflammation)" and "sunburn (tissue damage)".
3. Collaborative repair with sunscreen agents
Can be compounded with sunscreen to block UV rays while repairing residual UV triggered damage signals at the cellular level. This is the complete logic of "external defense+internal repair" - sunscreen is the first line of defense, and neptide-1 is the second line of defense.

1. Stimulate blood flow
Can stimulate derma microcirculation and increase blood flow. One of the important reasons for dull and tiredderma is poor microcirculation - nutrients cannot be delivered and waste cannot be discharged. By promoting microvascular dilation, the "nutrient supply line" of the derma is improved.
2. Improve eye bags and swelling
Its characteristic of promoting blood flow also has a certain improvement effect on eye bags and facial swelling.

Although this is not its main application direction, it often appears as an auxiliary active ingredient in eye repair products.
3. Enhance the overall "vitality" of the skin
User feedback shows that after continuous use of the product, the derma appears "rosy and shiny" instead of pale "false white". This is a comprehensive manifestation of microcirculation improvement, accelerated cell renewal, and complete barrier repair.

1. Postoperative repair
Without cytotoxicity and anti-inflammatory properties, it has potential for application in the "barrier rupture period" after laser surgery, microneedling surgery, and fruit acid derma replacement surgery. It does not stimulate the exposed dermis layer, but instead accelerates wound healing by promoting cell proliferation and collagen synthesis.
2. Chronic wound repair
Although currently mainly used in the cosmetics industry.

Its multiple mechanisms of promoting cell proliferation, enhancing ECM synthesis, and regulating inflammation are highly consistent with the core requirements of chronic wound repair. In ECM hydrogels, collagen dressings and other new dressings, the research on active additives is being promoted.
3. Repair perspective in anti skin cancer research
Nonapeptide-1 skincare, as an MC1R antagonist, is used as a pharmacological tool in derma cancer research. From a repair perspective, its precise regulation of the melanocyte signaling pathway provides a new perspective for understanding the repair failure mechanism of "abnormal proliferation → carcinogenesis".
