This ingredient features dual applicability for external topical use and oral intake.
For external application, it penetrates the stratum corneum; its hydrophilic functional groups lock in moisture to hydrate skin and repair cutaneous barrier, restrain melanin synthesis, alleviate photodamage, smooth fine wrinkles and slow down endogenous collagen depletion. When taken orally, the peptides undergo rapid gastrointestinal absorption without prior digestive breakdown, supporting intestinal mucosa restoration and gastrointestinal function regulation, as well as accelerating granulation tissue regeneration and wound healing after surgical procedures.
Our Products Form
Fish Collagen Peptide COA
The product appears as off-white or pale yellow homogeneous fine powder free of peculiar odors and visible impurities. In dry powder form, it features chemically inert characteristics with strong resistance to spontaneous oxidative deterioration and outstanding storage stability.
Possessing superior water solubility, the powder dissolves rapidly in both cold and warm water to form clear, colorless, homogenous aqueous solutions without sedimentation or phase separation, distinguishing itself from macromolecular collagen which is poorly soluble and prone to flocculation.
Its molecular weight is predominantly distributed within the range of 1000–3000 Da. The low-molecular-weight structure endows the peptide with remarkable transdermal penetration capacity and chemical reactivity; its aqueous solution is neutrally pH-balanced, compatible with most cosmetic formulations and physiological acid-base environments of human bodies.
The material exhibits favorable thermal stability and avoids peptide chain cleavage or denaturation under conventional processing temperatures, yet cannot withstand extreme conditions of strong acid, strong alkali or ultrahigh temperature; harsh acidic or alkaline surroundings break peptide bonds, deactivate bioactivity and trigger component degradation.
Abundant polar functional groups including hydrophilic hydroxyl and amino groups are distributed on molecular surfaces, generating powerful hydrophilic adsorption capacity. Its stable molecular structure prevents antagonistic chemical interactions with cosmetic and personal care raw materials, enabling excellent formulation compatibility as a safe and efficient functional raw material.
Total crude protein content reaches ≥90% on a dry basis, featuring high purity and low impurity levels, whose physicochemical indices satisfy dual application requirements for topical skincare & body care and oral nutritional supplementation.
in Skincare Products (Transdermal Hydration for External Use)
Benefiting from low-molecular-weight transdermal permeability, high hydrophilicity and biological repairing activity, fish collagen peptide powder serves as a core functional raw material for premium skincare formulas. It crosses the superficial epidermal barrier to target the stratum corneum and superficial dermis, delivering multi-efficacy including moisturization, barrier repair, anti-aging and skin brightening, and is widely incorporated into diversified facial skincare commodities.
In mainstream skincare items such as facial masks, serums, creams and facial toners, its core strengths lie in long-lasting transdermal moisturization and skin barrier rehabilitation.
Dense hydrophilic moieties on peptide molecules efficiently bind moisture within the stratum corneum and lock intrinsic cutaneous water to reduce transepidermal water loss (TEWL), overcoming the limitation of conventional moisturizers that only replenish surface moisture and enabling all-day deep hydration to relieve dryness, roughness and flaking.
Meanwhile, the ingredient inhibits tyrosinase activity in skin cells to curb melanocyte proliferation and melanin biosynthesis at source, fade superficial dullness and pigmented spots and even out skin tone.
Against UV-induced erythema, burning sensation and oxidative damage, source of seafish neutralizes free radicals on skin surface, ease inflammatory reactions from photodamage, reconstruct impaired stratum corneum, thicken skin barrier and elevate cutaneous tolerance. Furthermore, specific bioactive short peptides (GYTGL, LGATGL included) selectively bind with native dermal collagen, suppress endogenous collagen degradation in dermis, slow skin sagging and aging and preserve skin firmness.For anti-aging subdivided products such as eye serums and anti-wrinkle concentrates, source of seafish acts as a high-potency polypeptide for wrinkle reduction and skin tightening.
Periorbital skin is thin and vulnerable to rapid collagen loss, susceptible to dry fine lines, wrinkles and sagging. Small-molecule source of seafish permeates periorbital tissue swiftly, supply bioactive peptide nutrients, stimulate fibroblast viability and facilitate de novo synthesis of endogenous collagen and elastic fibers. Persistent application fills skin texture, blurs static dry lines and fine wrinkles, lifts saggy periocular skin and alleviates periorbital puffiness while maintaining hydrated, smooth eye skin without the drying side effects common to ordinary anti-aging formulations, matching the mild anti-aging demands of delicate periorbital tissue.
in Daily Cleaning & Personal Care Products
Within body cleansing formulations, its primary functions cover dryness relief and epidermal barrier rehabilitation. Added into body wash, fish collagen peptide powder prevents cleansing surfactants from stripping natural cutaneous lipids and surface moisture during washing, realizing gentle cleansing without compromising skin barrier and leaving refreshed non-tight skin post-bathing. For seasonal flaking, pruritus and body roughness triggered by cold dry climate, body lotions supplemented with the peptide rapidly infiltrate body stratum corneum to sustain long-acting water retention, relieve dry cutaneous inflammation, repair impaired body skin barrier and improve inherent water-locking capacity, fundamentally eliminating dry flaking, roughness and dullness for long-term all-body moisturizing maintenance.
Gastrointestinal Regulation and Post-Surgical Wound Repair Effects
Featured with outstanding biocompatibility and rapid oral absorption, source of seafish exerts dual oral benefits for gastrointestinal mucosa conditioning and postoperative wound repair with favorable safety and high bioavailability, suitable for daily gut healthcare and postoperative recuperation populations.
For gastrointestinal maintenance: Source of seafish functions as premium nutritional raw material to protect intestinal mucosa and optimize enteric health.
Rich glycine and proline serve as fundamental building blocks for tight junction proteins of intestinal epithelial cells, accelerating mucosal cell proliferation and regeneration, repairing inflamed, edematous or slightly damaged intestinal lining, enhancing mucosal barrier integrity, blocking invasion of harmful intestinal substances and lowering the incidence of enteric inflammation. Its short-peptide microstructure bypasses complicated gastrointestinal digestion for direct intestinal uptake without imposing digestive burden.
Meanwhile, it balances intestinal microecology by stimulating proliferation of beneficial flora including Bifidobacterium and suppressing pathogenic bacteria overgrowth, improving digestive and absorptive functions to relieve irritable bowel syndrome, indigestion, abdominal distension and other gut discomforts, delivering auxiliary conditioning effects for patients with chronic gastritis and mild intestinal injury.For postoperative rehabilitation: Source of seafish accelerates wound closure and physical recovery after general surgery and minimally invasive aesthetic procedures.
Postoperative patients usually suffer physical debilitation, declined cellular regenerative capacity, slow wound healing and elevated risks of inflammation and hypertrophic scarring. Bioactive components including arginine and hydroxyproline upregulate endogenous transforming growth factor expression, facilitate granulation tissue formation and epithelial cell regeneration, boost angiogenesis at wound sites and optimize local microcirculation to deliver sufficient nutrients for wound regeneration and markedly shorten healing cycles.
