The Hydrogel Mask That Broke the Internet

Biodance is a Korean dermocosmetic label run by Beautyselection Co., founded in Seoul in 2020 and launched as a skincare brand a year later, in 2021. In just a few years it went from indie start-up to one of Korea's most talked-about beauty exports — almost entirely on the strength of one product: a hydrogel sheet mask that turns clear as it's absorbed into your skin. The brand's philosophy is simple — "Better Formula for Better Glow" — and its team is known for testing weight and texture down to the gram until they landed on a gel that clings to the face without sliding off, stays comfortable overnight, and lets you literally watch the essence sink in. That obsessive formulation is why skincare fans now treat Biodance as shorthand for "hydrogel done right."

Inside the Glow Vault: Biodance's Cult-Favorite Lineup

• Bio-Collagen Real Deep Mask — the mask that made the brand famous. A hydrogel sheet packed with low-molecular collagen for firmness and deep hydration, gentle enough to sleep in overnight.
• Hydro Cera-nol Real Deep Mask — a ceramide-based, barrier-repairing version for sensitive or dry skin.
• Sea Kelp & Vita Real Deep Masks — lighter, brightening variants from the same Real Deep line.
• Jelly Serum Mist Duo — a spray-on hydrogel mist for a lightweight gel finish, great for travel and midday touch-ups.
• Serums — Pore Perfecting Collagen Peptide Serum, Hydro Cera-nol Serum, and Radiant Vita Niacinamide Serum bring the mask's key ingredients into everyday routines.

0.5 Seconds a Sale: How Biodance Went Viral Worldwide

The Bio-Collagen Real Deep Mask didn't blow up through a celebrity campaign — it blew up on skincare TikTok and Instagram, where people filmed themselves peeling off a mask that had turned almost see-through from absorption. That visible "before and after" made it one of Korea's most viral skincare exports, with the brand reporting it sells at a pace of roughly one sheet every half-second globally, and well over 100 million sheets sold since launch. After debuting on Amazon in late 2022, it climbed to the top of Amazon's skincare bestseller charts within about two years — a rare feat for an independent Korean brand.
