The Autophagy Inducer for Deep Cellular Self-Cleaning and Renewal
Spermidine HCl is a potent cosmetic grade polyamine and a breakthrough in longevity-focused skincare. It acts as a primary inducer of autophagy—the natural process of cellular self-cleaning—allowing skin cells to break down and recycle damaged components, thereby restoring youthful function and vitality.

Shaanxi Huatai Bio-fine Chemical Co. provides premium cosmetic grade Spermidine HCl, characterized by its proven autophagy-inducing activity and exceptional stability. Our unique advantage lies in the high-purity crystalline form of these active ingredients skincare, which ensures maximum bioavailability for skin cells to trigger the “cleanup” of metabolic waste. As a signature active for “Longevity” and “Bio-hacking” skincare lines, our Spermidine HCl empowers brands to offer true cellular rejuvenation that goes beyond surface-level repair, effectively extending the healthy lifespan of skin tissue.
Spermidine HCl is a natural polyamine involved in critical cellular processes including DNA stability and protein synthesis.
It is highly valued for its ability to simulate the anti-aging benefits of caloric restriction at the skin’s cellular level.
Our Spermidine HCl is refined to maintain peak bioactivity while ensuring compatibility in diverse formulations.
Purity: ≥ 98.0%.
Heavy Metals: < 10 ppm.
Loss on Drying: ≤ 1.0%.
Stability: Highly stable in aqueous systems; best kept in a cool, dry environment away from strong oxidants.

Autophagy Induction: Inhibits EP300 activity, leading to the acetylation of autophagy-related genes and triggering the cellular recycling process.
Mitochondrial Protection: Enhances mitochondrial function, reducing oxidative stress and increasing cellular energy (ATP) production.
Barrier Reinforcement: Promotes the synthesis of structural proteins in the epidermis to strengthen skin defense.
Longevity Trend Leader: Directly addresses the “Autophagy” and “Cellular Longevity” trends popular in premium European and Asian markets.
Holistic Rejuvenation: Improves skin texture, elasticity, and radiance by clearing “cellular clutter”.
High Efficiency: Effective at low concentrations, allowing for easy integration into complex anti-aging complexes.
Recommended Usage: 0.01% – 0.5%.
Processing: Highly water-soluble; can be easily added to the water phase of emulsions or used in clear serum systems.
pH Range: Stable within a pH range of 4.5 – 6.5 for optimal formulation integrity.
Our manufacturing facility is ISO 9001/22000 and HALAL certified.
We strictly adhere to COSMOS approved standards, ensuring our raw materials meet natural and organic cosmetic criteria.
Every batch of our cosmetic grade Spermidine HCl is provided with a full technical dossier, including COA, TDS, and MSDS.
Spermidine HCl + Fisetin: A powerful “Longevity Duo” that clears zombie cells and induces autophagy for complete rejuvenation.
Spermidine HCl + Ergothioneine: To protect newly “cleaned” cells from fresh oxidative damage.
Spermidine HCl + Sodium DNA: To provide the building blocks for regeneration after cellular cleanup.
This ingredient is a core component in “Cellular Renewal Serums,” “Longevity Creams,” and “Advanced Detox Masks”.
Brands using our active ingredients skincare have successfully launched products focusing on “Biological Age Reversal”.
Extensive scientific research highlights Spermidine as a critical agent for delaying aging across various biological models by activating autophagy.
Internal lab data confirms that Spermidine-enriched formulas significantly enhance skin barrier function and overall skin density over a 6-week period.
