Comes from a smoke pet free home! Price firm thank you! Patricia Wexler M.D Skin Regenerating Serum MMPi 20 .5 fl oz / 15 mL each Comes with set of 2 of the .5oz jars Never used! - it’s not a liquid serum more of a gel-cream consistency Discontinued & extremely difficult to find Some may vary in appearance but they all have the same amount .5oz and all brand new and unused! I do have multiples of this item if you'd like to buy more!
