What Korean Buyers Say
- As a sensitive skin type, it did not feel overly burdensome. However, it pills before makeup, so I mainly use it at night.
- It significantly reduced my redness and stubborn blemish marks. It stung initially so I mixed it with lotion, but my skin adjusted and now I apply it directly without stinging.
- This is a steady repurchase item for me. Because of my sensitive skin, I mix it into my moisture cream, and it leaves my skin feeling firm and resilient.
