I could feel the effects the day after using it. [Good points] 1. The texture is smooth and easy to spread all over my face! 2. My face doesn't feel sticky after application! 3. I noticed a difference in the moisture level of my skin just by washing my face the day after use! 4. It's large, and contains a relatively generous amount compared to other serums! [Points to improve] 1. The dropper is harder to suck up than other brands. [Tips for use] You can quickly spread it over your face when you want to get some serum in the morning and evening, or you can use a beauty device in conjunction with your skincare routine the day before a big day to let it absorb thoroughly! Toridden also makes masks, so I recommend using the same series for intensive care.
