Kerassentials is manufactured in an FDA-approved facility, ensuring it meets high standards of quality and safety. However, as with many dietary supplements and topical solutions, Kerassentials itself is not individually FDA-approved because the FDA does not typically evaluate supplements. Despite this, the manufacturing process follows strict GMP (Good Manufacturing Practices) guidelines, ensuring pharmaceutical-grade quality. Customers can feel confident that Kerassentials is produced in a safe environment, but it's always wise to consult a healthcare provider before starting any new product.
