Hello, after sometimes finally can give you review about this mask! Thanks @raikubeautyfor letting me try your new product.This is Raiku Brightening Mask. This product contains Caviar Extract, Niacinamide, Sodium Hyaluronate and Collagen. It is good for hydrating and brightening your skin.I've been using this for a week as sleeping mask and surprisingly it is super easy to absorb. Maybe the easiest of all sleeping mask I've tried. It does hydrating and plumping my skin. However I have not seen the brightening effect yet on my skin. Will update you more kn my blog after some more times.@onie_callista #Raiku #RaikuBeauty #RaikuLeaveonMask #RaikuBrighteningMask
