1. Total Photon Barrier Protection
Unlike amber glass, our ultra-opaque black glass blocks 100% of visible and UV light (200-800nm), completely eliminating photodegradation risks for even the most light-vulnerable ingredients-including retinoids, certain antibiotics, essential oil terpenes, and psychedelic compounds. The glass undergoes specialized ion-exchange tinting to achieve consistent, jet-black opacity without reducing structural integrity.
2. Security Closure Options
A. Tamper-Evident Dropper Assembly
One-time breakaway ring audibly separates upon initial opening

B. Penguin-Style Emulsion Pump
Low-profile cylindrical actuator enables directional, non-aerosol dispensing

Output: 0.20ml per pump stroke, suitable for viscosities up to 4,000cps
C. Press-Turn Child-Resistant Cap
