Surface Clinical in Dallas is a treasure. For Christmas one year I gave my mother some TNS by Skin Medica.  Mama has some of the prettiest skin I know of for her age.. Part of it is that she has stayed out of the sun. Huge Help. But she loves this eye product and sees a difference.. Liz and Mary are superb at recommending products.  I swear by them.  The TNS serum is one product that helps rebuild collagen, and boy I have lost a lot of that in the last 10 years. I also gave it to my daughters who need way less sun exposure and who are learning at an earlier age how to take care of their skin.  This is not a “happy,” it is an investment gift.. But this does give good returns.
