If you need more comparative analysis of brand models, please contact HiSiaddi customer service.
The partner is DermaVital Laboratory based in Milan, Italy, a local mid-to-high-end medical beauty clinic skincare brand with over 30 years of experience specializing in essences, eye creams and post-procedure repair essences exclusively supplied to private medical beauty clinics. Its products hold EU SCCS safety certification and Italian COSMEBIO organic natural certification, covering more than 260 high-end medical beauty institutions and light luxury drugstore collection stores across Southern Europe including Italy, Spain and Austria.
All skincare products of the brand feature high-activity streamlined formulas, and acetyl hexapeptide-8 serves as the core functional raw material for three flagship anti-aging products: 10% high-concentration anti-wrinkle stock solution, firming anti-wrinkle eye cream and AHA exfoliating repair lotion. For over 20 years, raw materials were exclusively purchased from Spain’s Lipotec original Argireline® acetyl hexapeptide-8. Affected by continuous price hikes of European local raw materials, extended sea freight cycles and delayed scheduling for small-batch orders from original manufacturers, the brand launched research on domestic raw material substitution in 2025, with an estimated annual procurement volume of 7.2 tons of acetyl hexapeptide-8 delivered in batches by quarter.
The client’s R&D director is a senior Italian cosmetic formulator familiar with EU raw material regulations and formula compatibility logic, yet completely unfamiliar with mainstream domestic acetyl hexapeptide-8 manufacturers, product line classification of each brand, physical and chemical parameters of different models and applicable formula scenarios. Between March and April 2025, the client independently contacted 5 leading domestic peptide raw material factories via email and video: Zhejiang Peptide Biotech, Bloomage Biotech, Vicky Tech, Shandong Jipeptide Biotech and Gotop Biotech.
All five factories operate legally without maliciously belittling competitors, yet restricted by corporate sales orientation, they only focus on promoting their own product advantages and avoid objective comparison of technical highlights, applicable scenarios and shortcomings of competing brands: Peptide Biotech prioritizes its mass-produced general liquid model without mentioning the advantages of Bloomage Biotech’s compound modified hexapeptide; Bloomage Biotech focuses on its own high-purity powder grades without introducing the characteristics of Vicky Tech’s low-temperature stable solvent formulas; Vicky Tech mainly promotes organic solvent product lines and refuses to objectively elaborate the matching advantages of Jipeptide Biotech’s cost-effective high-purity powder.
The client received a total of 11 free samples from the five factories, yet lacked horizontal parameter comparison and standardized selection logic, unable to distinguish essential differences between general industrial grades, high-end clinic customized grades and organic certified grades. Multiple samples presented problems including low-temperature crystallization, discoloration when compatible with AHA formulas and inconsistent activity loss during storage during independent lab testing, halting sample development for nearly one month and delaying the new product launch schedule.
The client finally entrusted Shanghai HiSiaddi, a technology-driven foreign trade service provider, to fully sort out the matrix of domestic leading brands, horizontally disassemble all series models of 3-5 mainstream brands, screen suitable mid-to-high-end raw materials based on the client’s formula demands and complete final selection and procurement.
HiSiaddi specializes in import and export technology foreign trade of cosmetic peptides, with core strengths including neutral third-party selection, parallel horizontal raw material evaluation and formula implementation support. It is not bound to any single raw material factory and can objectively analyze the advantages and disadvantages of products from each brand.
After accepting the project, combined with the formula attributes of the client’s three products (high-addition serum, high-oil eye cream, weak-acid AHA lotion), EU organic marketing claims, SCCS raw material filing, finished product shelf life ≥18 months and no crystal precipitation under -5℃ low-temperature storage, HiSiaddi selected five mid-to-high-end leading domestic raw material enterprises: Zhejiang Peptide Biotech, Bloomage Biotech, Shenzhen Vicky Tech, Shandong Jipeptide Biotech and Hangzhou Gotop Biotech.
It collected COA test reports, production process documents, compliance qualifications and terminal application cases of each brand one by one, neutrally analyzed the brand positioning, mainstream models, product strengths, defects and applicable formula scenarios of each enterprise, and issued a bilingual Chinese-English brand evaluation report. Meanwhile, it coordinated each brand to send corresponding standard samples, which were uniformly submitted to a third-party authoritative testing institution with EU recognized qualifications for parallel physical and chemical tests (purity, free amino acids, heavy metals, low-temperature stability, acid-base compatibility stability).
Brand Positioning: Benchmark enterprise of domestic peptides, covering both mass-market daily chemical and mid-to-high-end clinic raw material product lines. Three mainstream models of acetyl hexapeptide-8: ① PT-L20 (20% petrochemical propylene glycol general liquid grade): Core mass-produced bulk commodity of the factory, purified by single column chromatography with free amino acids ≤0.3%, outstanding cost advantages, suitable for affordable daily chemical lotions, creams. Shortcoming: Trace short peptide crystals easily precipitate under 5℃ low-temperature storage, incompatible with the client’s high-oil eye cream and AHA formulas. ② PT-P995 (99.5% high-purity powder grade): Purified by secondary reverse chromatography with free amino acids ≤0.14% and heavy metals ＜0.08%, indicators benchmarking European imported powder raw materials, suitable for high-concentration powder compound serums. Strengths: Large-scale mass production and stable delivery cycles. ③ PT-O5 (5% corn plant propylene glycol organic liquid grade): Non-GMO corn fermented solvent free of petrochemical solvent residues, passing pre-review of EU natural raw materials, suitable for skincare products with organic marketing claims. Shortcoming: High minimum order quantity for single product (≥500kg per order), high cost for flexible small-batch replenishment.
Overall Brand Strengths: All production lines pass ISO22716 cosmetic GMP certification, with an annual hexapeptide output exceeding 30 tons and a large global customer base for exports. Shortcoming: Loose impurity control standards for general grades, only high-end grades meet strict EU clinic standards.
Brand Positioning: R&D-oriented leading raw material enterprise developing compound modified hexapeptide relying on patented hyaluronic acid technology. Three core models: ① HA-L20-HA (20% hexapeptide + ultra-low molecular weight hyaluronic acid compound stock solution): Original patented pre-compounded formula with pre-stabilized compatibility between hexapeptide and hyaluronic acid, eliminating secondary compounding procedures in the client’s workshop and directly filling eye cream, perfectly matching the client’s firming eye cream formula with no delamination or crystallization after 30 days of refrigeration at -5℃. ② HX-P996 (99.6% medical-grade high-purity powder): Purified by three rounds of chromatography and freeze-drying, with impurity indicators superior to national standards and general EU standards, exclusively supplied for medical-grade high-activity clinic serums. ③ HX-STD20 (general 20% propylene glycol liquid grade): Mass-market daily chemical base grade, only compatible with neutral conventional serums, intolerant to strong acid and low temperature.
Brand Strengths: Unique compound modification technology in the industry with complete supporting EU compliance filing documents. Shortcoming: Quotations for pure hexapeptide single products are higher than Peptide Biotech and Jipeptide Biotech, and general grades have weak cost performance.
Brand Positioning: Deeply engaged in domestic mid-to-high-end clinics and European and American export drugstore markets, focusing on low-irritation organic solvent product lines. Two core models: ① VQ-O20 (20% plant propylene glycol liquid hexapeptide): Full line adopts non-GMO corn fermented propylene glycol free of petrochemical solvent residues, all impurity indicators meet COSMOS organic certification standards with excellent stability under weak acid environments, suitable for the client’s AHA exfoliating lotion. ② VQ-P994 (99.4% high-purity powder): Flexible pilot production lines support flexible small-batch customization with low minimum order quantity (orders starting from 100kg). Shortcoming: Unit price rises significantly for large-batch orders.
Brand Strengths: Complete organic raw material qualifications with abundant successful cooperation cases with European organic brands. Shortcoming: Few layouts of general petrochemical solvent product lines, and mass spot production capacity lags behind Peptide Biotech and Bloomage Biotech.
Brand Positioning: Focused on solid-phase synthesis and purification processes of peptides, specializing in high-purity powdered hexapeptide. Core model JT-P995 (99.5% high-purity powder), with only small customized batches of liquid products available. Strengths: Mature powder purification technology with free amino acids ≤0.13%, and unit prices of high-purity powder lower than Bloomage Biotech and Vicky Tech with sufficient spot inventory. Shortcoming: Limited production capacity of liquid products and no self-developed compound hexapeptide models.
Brand Positioning: Focused on small-batch peptide customization. Core models: GT-L20 general liquid and GT-P993 high-purity powder. Product indicators meet national standards, yet high-end grades lack EU pre-filing documents. Strengths: Free small-batch sample testing and flexible formula revision. Shortcoming: Insufficient large-scale mass production capacity, unable to stably supply annual long-term orders of 7-ton level, failing to meet the client’s annual procurement demand.
Combined with the differentiated formula demands of the client’s three products, HiSiaddi finally selected two suppliers: Zhejiang Peptide Biotech and Shenzhen Vicky Tech, with three matching models: Peptide Biotech PT-P995 high-purity powder, Peptide Biotech PT-O5 organic 5% liquid and Vicky Tech VQ-O20 organic 20% liquid. The three raw materials correspond to the client’s three core products respectively, with detailed selection logic and sample verification as follows:
1.
Peptide Biotech PT-P995 (99.5% High-Purity Powder Acetyl Hexapeptide-8) → Client’s 10% High-Addition Anti-Wrinkle Serum The client’s serum has a high hexapeptide addition rate of 10%, requiring high-purity powder to prepare high-concentration stock solution. This model has free amino acids ≤0.14% and heavy metals ＜0.08%, with indicators benchmarking original Spanish Lipotec powder. Third-party accelerated stability testing shows the retention rate of hexapeptide activity reaches ≥91% after 18 months of normal-temperature storage, completely resolving the previous problem of rapid activity loss of general raw materials. The client completed 5kg lab testing with transparent, turbid-free serum finished products and no precipitation after 3-month accelerated aging, complying with EU SCCS raw material standards. Annual procurement volume: 2.4 tons delivered in 6 batches monthly.
2.
3.
Peptide Biotech PT-O5 (5% Plant Propylene Glycol Organic Liquid Hexapeptide) → Client’s High-Oil Firming Eye Cream The eye cream adopts an oil-heavy O/W emulsification system requiring low-concentration organic solvent hexapeptide with no crystallization under low temperature. This model uses corn-based propylene glycol solvent free of petrochemical impurities, with no white crystal precipitation after 30 days of -5℃ cycle testing, resolving the pain point of filling pipeline blockage caused by general propylene glycol raw materials. The raw material is equipped with EU natural raw material pre-review documents to support the brand’s organic skincare marketing claims. Annual procurement volume: 2.1 tons delivered by quarter.
4.
5.
Vicky Tech VQ-O20 (20% Plant Propylene Glycol Organic Liquid Hexapeptide) → Client’s 5% Compound AHA Exfoliating Repair Lotion The client’s exfoliating lotion adopts a strong acid system with pH 3.4-3.8, and ordinary hexapeptide tends to hydrolyze and discolor when in contact with AHA. This model from Vicky Tech is pre-configured with a pre-stabilized buffer system, showing no delamination or yellowing after 72 hours of compatibility under weak acid environments. It is the only 20% organic liquid model among the five brands that fully passed all compatibility tests of the client’s AHA formula. The raw material holds COSMOS organic raw material certification documents, which can directly assist the client with local raw material filing in Italy. Annual procurement volume: 2.7 tons.
6.
HiSiaddi simultaneously coordinated the two factories to issue bilingual Chinese-English COA, GHS English MSDS and itemized impurity test reports required for SCCS filing in accordance with EU standards, eliminating compliance risks for the client’s EU customs clearance and local filing. To address the client’s concerns, it coordinated free supply of 5kg pilot samples from each factory, all shipped to the R&D laboratory in Milan, Italy for human patch tests, finished product stability tests and in vitro anti-wrinkle efficacy tests. The efficacy difference between finished products formulated with the three raw materials and original Spanish raw materials was less than 4%, all passing the client’s internal quality control acceptance.
After 45 days of brand sorting, parallel evaluation, formula sample testing and qualification verification, DermaVital Italy formally signed an annual framework procurement contract with Peptide Biotech and Vicky Tech. The total annual volume of 7.2 tons of raw materials was exported to Genoa Port, Italy in 13 batches. HiSiaddi fully tracked the whole process including production scheduling, factory inspection, customs clearance and export, and technical docking after arrival at the port.
The comprehensive procurement cost of the three domestic raw materials decreased by 28.7% compared with original Spanish Lipotec raw materials. New anti-aging serums, eye creams and AHA exfoliating lotions were launched across all medical beauty clinics in Italy as scheduled, with terminal sales surging by 32% year-on-year in the first quarter after launch. The client renewed an annual procurement framework of 9 tons the following year and added demand for domestic selection of palmitoyl tripeptide and pentapeptide.
Supported by this annual long-term order from a mid-to-high-end Italian clinic brand, Peptide Biotech and Vicky Tech optimized standardized production SOPs for high-end grades. The export premium of high-end organic hexapeptide series reached 29%. Relying on this successful implementation case, they subsequently developed multiple mid-to-high-end skincare brands in Greece and Portugal.
A domestic leading brand selection database for acetyl hexapeptide-8 was established, forming a standardized mid-to-high-end raw material selection service process: client formula demand research → neutral disassembly and evaluation of multiple brands → third-party parallel testing → accurate model matching → complete compliance supporting implementation. HiSiaddi has continued to undertake peptide selection and procurement orders from multiple clinic brands in France and Switzerland thereafter.
Restricted by sales mechanisms, domestic peptide manufacturers generally prioritize promoting their own products and refuse to objectively elaborate the advantages of competing brands. Overseas mid-to-high-end brands are unfamiliar with the grading system of domestic raw materials, easily selecting low-end general grades by mistake and resulting in scrapped formulas. As a third-party service provider maintaining a neutral perspective and free from the interests of a single brand, HiSiaddi horizontally disassembles the advantages and disadvantages of each brand in full dimensions and accurately matches raw material models based on formula scenarios, achieving a three-party win-win: cost reduction for overseas clients, entry of domestic raw materials into European high-end clinics and business expansion for service providers.
