At the first few attempts, I felt that the mask was not moisturising enough. Therefore I went back to the counter and ask the BA about it. She told me that I should not wash off the mask with water. Instead, I should wipe it off with Hydrabio Moisturising Lotion (水活保濕爽膚液 ). The moisturising effects is much more evident and long lasting. I am currently doing laser treatments which dry out the skin however the mask can help with keeping the skin moisturise. Highly recommended.
