Name: Biodance Bio-Collagen Real Deep Mask
Brand: Biodance

What is this product?

A hydrogel sheet mask sold in 4 and 8 sheet packs, designed for long wear and marketed as usable overnight. The reason to pick it: the label is unusually clean for reactive skin, with no fragrance entry, no essential oil, no drying alcohol, no exfoliating acid and no labelled allergen across 34 entries, and the brand does hold 미백/주름 개선 functional cosmetic status with niacinamide at position 5 and adenosine at 21 backing it. The reason to read the label twice: 콜라겐추출물 is printed as 55,000ppb, which is parts per billion, so it equals 55 ppm or 0.0055 percent, and the entry sits at position 25 of 34, below the chelator. The reasons to skip it: the 34 entries contain no lipid at all, so a cream has to follow; no clinical, human application or irritation test is cited by any surface examined here, with 임상, 시험 and 인체적용 each returning zero in every layer of all three archived files; and the 누적 판매 1.65억장 figure names no period, territory or source. No aggregated review data was available for this product, so this record publishes none.

What makes it different?

A long-wear hydrogel mask with a functional cosmetic filing on two axes and a genuinely bare label, whose headline collagen figure is printed in parts per billion and therefore reads about a thousand times larger than the inclusion it describes.
