N‑Acetylneuraminic Acid (Sialic Acid) Raw Material Introduction

N‑Acetylneuraminic acid (Neu5Ac, commonly known as bird’s nest sialic acid) is a nine‑carbon amino monosaccharide and an active ingredient applicable for both food and cosmetic use, manufactured via microbial fermentation. In food applications, N‑acetylneuraminic acid participates in nervous system development, maintains mucosal immunity and exhibits antioxidant activity. In cosmetics, it repairs the skin barrier, scavenges free radicals to deliver anti‑aging effects and modulates melanin synthesis. This article reviews the physicochemical properties and mechanism of action of the ingredient, as well as regulatory requirements and applicable product categories for its use in food and cosmetics in China.

Poly-L-Lactic Acid (PLLA): Current Applications and Global Regulatory Landscape of a Regenerative Injectable Material

Against the backdrop of a rapidly growing regenerative medical aesthetics market, poly-L-lactic acid (PLLA) has long transcended the positioning of an ordinary filler material and become a globally recognized benchmark collagen-regenerative material in the field of facial rejuvenation. Unlike hyaluronic acid, which provides immediate physical volume replacement, PLLA is characterized by complete biodegradability and long-term stimulation of autologous collagen neogenesis. Over more than two decades of global clinical application, it has gradually built a reputation for both safety and long-term efficacy. With the recent acceleration of regulatory approvals for regenerative materials in China, clarifying its clinical progress and global regulatory framework is essential reference for industry practitioners and consumers alike.

L-Ergothioneine

Technical Review2026.08.21

From Laboratory to National Anti-Aging Boom: A Comprehensive Overview of Ergothioneine's Application Status

Ergothioneine (L-Ergothioneine, abbreviated as EGT) is a natural sulfur-containing amino acid derivative discovered in ergot fungi in 1909. Its molecular formula is C₉H₁₅N₃O₂S, with CAS No. 497-30-3. The pure product appears as white crystalline powder, is easily soluble in water, and will not auto-oxidize at physiological pH. It is a potent antioxidant that the human body cannot synthesize independently and must be ingested through diet or supplements. It has a dedicated OCTN1 transporter, which can target and accumulate in organs with high oxidative stress such as the liver, skin, and brain. In 2020, Nature listed it as a longevity-related biomarker.

OCT Piroctone Olamine: A Mild and High-Efficiency Mainstream Anti-Dandruff Raw Material

Dandruff and scalp itching are extremely common scalp problems, and anti-dandruff active raw materials are the core of hair care formulations. Among numerous anti-dandruff ingredients, OCT (Piroctone Olamine) has become one of the most widely used anti-dandruff raw materials in mid-to-high-end scalp care products, thanks to its advantages of mild low irritation, wide compatibility, and suitability for rinse-off products. This article provides a comprehensive overview from multiple dimensions including raw material profile, mechanism of action, application fields, and formulation dosage recommendations, to serve as a reference for formulation R&D and product development.

3‑O‑Ethyl Ascorbic Acid : A Stable Vitamin‑C Derivative for Brightening and Antioxidant Performance

L‑ascorbic acid, also known as vitamin C, is a water‑soluble antioxidant widely used in personal‑care formulations for many years. Nevertheless, it suffers from drawbacks including susceptibility to oxidative discoloration, strict formulation pH requirements and relatively high irritation potential. As an ether‑modified vitamin‑C derivative, **3‑O‑ethyl ascorbic acid (VC‑ethyl ether)** combines good stability, skin‑penetrating capacity and mildness, making up for the shortcomings of conventional vitamin C. It has become a high‑performance popular raw material in modern skincare formulations. This article provides a comprehensive overview covering raw‑material profile, mechanism of action, application fields and formulation‑usage recommendations for reference by formulators and product developers.

Popular Regenerative Materials in Aesthetic Medicine: CaHA, PLLA, PDLLA, PCL

Regenerative biomaterials represent a core research track for aesthetic medical consumables. Calcium Hydroxylapatite (CaHA), Poly‑L‑Lactic Acid (PLLA), Poly‑DL‑Lactic Acid (PDLLA) and Polycaprolactone (PCL) are four mainstream bio‑active raw materials in the industry. All four materials are available in powder and microsphere forms, and can be processed into suspension or lyophilized semi‑finished products for OEM contract manufacturing. Nevertheless, they exhibit substantial differences in molecular crystalline structure, mechanical properties, hydrolysis behavior, in‑vivo inflammatory response and collagen‑inducing capacity. Quantified datasets obtained from extensive in‑vitro cellular assays, animal implantation studies and pre‑clinical researches provide critical references for formulation selection and process development.
