    Comments about Peter Thomas Roth FIRMx Growth Factor Extreme Neuropeptide Serum, 1 oz:

    I've been using FirmX serum since it came out. I'm always looking for something better, as a product junkie trying to look younger than 48 with very fair, oily, acne prone skin. For me, there's nothing better than this serum!
    Due to cost I use it only at night, 3 pumps. That covers my face and neck. It does take a couple of weeks to see results. I kept up with it because every morning my skin looked clearer, softer, lines between my brows (the 11's), mild crow's feet...all were softening. My skin has more elasticity than ever. No breakouts, as many products cause me. I don't notice a scent. In winter, I've used PTR Mega Rich Intensive Anti-Aging Cellular Creme on top of this serum however, it isn't necessary. This serum is the only "all in one" product. I don't use it directly on eyes, but around them.
    The top can be unscrewed and there's quite a bit of product in the cap to be removed by finger or q-tip.
    I cannot say enough genuinely terrific results I've had with PTR FirmX Serum. I've not found the same with PTR Resurfacer or Viz 1000.
    It isn't as expensive as it seems because I only use eye creme with it at night. Primer and foundation during the day. I love this well keep secret serum!
