Pharmaceutical ingredients are regulated as drugs by the FDA, must be pure, undiluted, conform to what is claimed, and have no impurities. Cosmetic-grade products (over-the-counter products) are not held to the same standard. They can be made with ingredients that are non-pure, may contain numerous filler ingredients, and offer minimal effectiveness. Medical grade products are put through vigorous testing using mass spectrometers to verify the ingredients used are pure. It is impossible to hide components from mass spectrometers, which means that all the medical-grade products that Amici MedSpa carry are pure and contain no fillers.
