The GLO32 Advanced Teeth Whitening System offers a gentle alternative to traditional peroxide-based whitening products. Utilizing coconut oil as its active ingredient, it aims to safely remove stains and discoloration without causing enamel damage, making it suitable for sensitive teeth.

This system appears well-suited for those seeking a gentle, cruelty-free teeth whitening solution, particularly individuals with sensitive teeth or ethical considerations.
