Used this serum a few years ago, but RNW wasn't available on Lyko back then. I happened to see it today and thought I would rate and review it since I was really satisfied with the product. I stumbled upon this serum by chance online and was captivated by how exciting the ingredients sounded. I hadn't heard of 4-terpineol before, but it's an antioxidant while also being anti-inflammatory, antibacterial, and more. 4-terpineol is the main ingredient in tea tree oil, and I'm a big fan of tea tree oil 🥰 The product comes in a dark dark brown glass bottle with a dropper that looks nice and feels a bit luxurious. The serum is light as water, so almost no viscosity at all, making it a bit harder to apply but it sinks in just as easily as water. It hardly smells like tea tree oil at all, just a little faintly, so there's nothing to worry about if you have a hard time with it. I really feel how gentle this serum is. And it's completely in line with K-beauty, which works more on prevention rather than treatment, and the formulations are much milder than what we have here in the West. Rarely anything that burns, etc. At the same time, I thought the serum worked quite well, it felt soothing on my skin. No miracles though, but I liked it. I think it might be a bit pricey for what it is, but not so bad really, and I could see myself buying this again. Unfortunately, I have no picture, as it was a while ago since I used the product. I want to give 4.6 stars, rounded up to 5 😊 #lykoreview #RNW #k-beauty
