Product description
Retinoin is a natural or synthetic derivative of vitamin A, belonging to the retinol class of compounds. It is primarily used to regulate skin cell growth, differentiation, and metabolism. It is a common prescription dermatology medication suitable for conditions such as acne and psoriasis, but must be used strictly according to a doctor's instructions.
Retinoic acid is obtained by chemically modifying vitamin A. It is available in natural extracts (such as all-trans retinoic acid) and synthetic forms. It regulates gene expression by binding to receptors in the cell nucleus.
In dermatology, tretinoin is the accepted gold standard for treating acne and promoting research on cellular anti-aging. Ultra-pure Tretinoin that closely complies with the strictest international pharmaceutical monographs is offered by TIANJIN YINAO.

GMP Certified Production
The production environment is the main quality indicator for pharmaceutical procurement. GMP (Good Manufacturing Practice) accredited facilities are the exclusive source of tretinoin from TIANJIN YINAO.

- Professional Logistics: To guarantee that the temperature stays constant from the production to your lab, cold-chain logistics services are available for large orders.
Critical Storage & Stability Protocol (Non-Negotiable)
Tretinoin is a very sensitive molecule that is vulnerable to heat instability and photodegradation. TIANJIN YINAO employs a laboratory-grade protection process to ensure 100% bioactivity upon delivery:
- Light Protection: To prevent all UV exposure, only amber glass vials or light-proof vacuum-sealed aluminum bags are used.
- Temperature Control: To avoid molecular isomerization, it must be transported and stored at low temperatures (usually -20°C or 2–8°C).
- Oxidation Barrier: To prevent oxidative deterioration during extended storage, it is sealed in an inert nitrogen atmosphere.
