Glass is non-reactive, meaning it preserves the purity and effectiveness of our formulations by preventing any interaction between the container and the ingredients. Unlike plastic, which can sometimes leach harmful chemicals like xenoestrogens (compounds that mimic estrogen in the body), glass ensures that your skincare remains free from potential contaminants. Additionally, glass is recyclable and reusable, making it a more sustainable, eco-friendly choice that reduces plastic waste and environmental impact.
