Since we know that what is applied to the skin topically can be absorbed systemically-it is important that we are cautious about what we put on our skin. Belli is the only skin care brand in the WORLD that utilizes a teratology screening process to screen for these teratogens. This ensures that no ingredients in our formulations have ever been linked to birth defects. Many commonly used skin-care ingredients are teratogens, even some organic ingredients are teratogens!
