Outstanding Product Features: Multi-Effective Formulas for All Skin Types
Guangdong Jingyan’s flagship vitamin C facial serum (model JT-02) is a standout, designed to address core skincare needs while being suitable for all skin types. Each 30ml (1FL OZ) bottle combines three key active ingredients:
- Vitamin C: A powerful antioxidant that neutralizes free radicals, brightens dull skin, reduces dark spots and hyperpigmentation, and stimulates collagen production to fight fine lines.
- Hyaluronic Acid: Delivers deep hydration, locking in moisture to keep skin smooth and plump, even for dry or sensitive skin.
- Vitamin E: Enhances skin protection, soothes irritation, and works with vitamin C to boost anti-aging effects.
The serum’s liquid form ensures easy absorption, and it’s free from parabens and silicones—meeting the growing consumer demand for clean, gentle skincare. Its 3-year shelf life also supports brands’ inventory management and long-term market presence.
