Biodance claims this mask will improve resilience, replenish moisture, soften wrinkles, firms the skin and boosts elasticity, leaving the skin visibly smooth and deeply hydrated after one use. This mask is designed to leave on the skin for 3-4 & can even be worn overnight. The key ingredients in this mask include oligo-hyaluronic acid, galactomyces & ultra-low molecule collagen. You’re supposed to wear this mask at least 40 minutes, but preferable for 3-4 hours or as an overnight mask. It's a 2 part hydrogel mask that fit my face pretty nicely. I wore it overnight & my results were great! My skin glowed, felt supple & moisturized.
