The mask has 500Da and has 12 layer complex. It has 100,000ppm of Ulleungdo deep sea water. This mask has waved structure for better and perfect fit. I use this once a week at night or whenever I feel the urge for a deep moisturization especially when my skin is long exposed outdoor.
đź’™Experience and Observations
I have not experienced any redness, stinging or irritations while using this. This product sure does deeply moisturize my skin preventing excess sebum production. It is non-sticky so it is not a burden using it prior to putting on makeup.
