20% Vit. C & E Ferulic Acid Serum
This is the most lovely serum I've used. After 3 weeks it has really lightened some dark spots very nicely. I'm excited to see the results in another month . It was a pleasure to interact with this company. No guessing after you pay. The confirmation of my order and updates were appreciated after dealing with another company that really dropped the ball with customer service. Thank you, Timeless Skin Care. I am very happy!
