Peter Thomas Roth does it again! Yes...Peter Thomas Roth Products pull off another amazing anti-aging product feat by formulating Peter Thomas Roth FirmX Growth Factor Extreme Neuropeptide Serum. The miracle serum moisturizes brilliantly, brightens up even the dullest of complexions, banishes fine lines and wrinkles and firms up sagging skin. It works by containing a patent-pending Growth Factor (Extreme NeuroComplex) along with multiple peptides, neuropeptides, and many more potent antioxidants and ingredients. Thank you Peter Thomas Roth for stepping up to the skin care plate (again!) and slamming it right out of the park!
