Due to the nature of my work, I am very careful about beauty. I have been using Viest cosmetics and also love their NMN supplements, which I found to be very effective. So, I was excited about the release of this new serum. The results surpassed my expectations, with excellent texture upon application and sustained skin firmness even the next day, making me feel the freshness of the ingredients. I will definitely continue using this serum 😊.
