The first time i ever used the product was when i spent the night at a friend.We were having a girly sleep over doing the “usual” facials and manicures. I tried the night serum not expecting anything spectacular, as i have very problematic skin with mood swings of its own.The next morning when I woke up I could immediately see a difference. My skin looked refreshed and revived with a flawless smooth feeling and glow. There is definitely something magical in this product. Definitely an investment purchase.
