BIODANCE’s Refreshing Sea Kelp Real Deep Mask is a cooling hydrogel sleeping mask designed to calm sensitive, acne-prone skin while helping balance oil and moisture for a clearer, smoother-looking complexion. With its jelly-like texture that clings comfortably to the face, the mask creates a fresh, soothing seal over the skin to support deeper absorption of active ingredients, making it especially helpful for redness, uneven texture, and skin “troubles.”

The formula is powered by lactobacillus/kelp ferment filtrate and seaweed-derived ingredients, including 10% fermented sea kelp extract, seaweed extract, and 5,000ppm mineral-rich deep sea water. Together, these ingredients help regulate excess sebum, improve the skin’s oil–moisture balance, and deliver calming hydration without heaviness. As you wear it, the mask feels pleasantly cooling, helping soothe irritation and leave skin looking more refined by morning.

To use, apply as the final step of your nighttime routine and leave it on overnight, then remove the next morning. The mask is dermatologically tested and skin irritation tested, and it is EWG Verified, certified without 19 controversial ingredients. It has also completed a skin hypoallergenic test and is free of allergens notified by Korea’s Ministry of Food and Drug Safety, making it a reassuring choice for sensitive skin types.
