We love to shop and we love to know what celebrities are up to, so, of course, stars’ product picks are right up our alley. The Real Housewives of Beverly Hills stars used these gold skin treatments during a spa day at Kathy Hilton’s house. You will feel like you’re at a spa (or Kathy Hilton’s house) when you use the Knesko Nanogold Repair Collagen Face Mask. It instantly firms, lift and hydrates the skin.
