Using cortisone cream as a spot treatment. Snail slime as a serum. A spray that cures eczema. Social media is full of beauty tips and product recommendations. And while some are totally bunk, others legitimately work. So, we were intrigued when we saw a new gel sheet mask making the rounds on TikTok and noticed that the same mask was trending on Amazon (sales were up 50%).

Lovers of the Biodance Hydro Cera-nol Real Deep Face Mask swear it gives them glass-like skin that is glowy and hydrated. But does it work? We looked into it.

Something to note

Should be worn overnight

Biodance’s mask is actually a sheet mask. Experts have previously told us sheet masks are particularly good for hydration because the occlusive nature traps moisture. However, just because they can hydrate your skin doesn’t mean they can replace other steps in your skin care routine. Meaning, using a sheet mask doesn’t mean you don’t need to apply your daily moisturizer.

These masks (there are four in a pack) are gel sheet masks, which means rather than a thin piece of paper or fibers, they’re made from a gel that feels cooling on your skin. Because of this, many reviewers note that they feel soothing and can calm minor irritations.

Which skin care ingredients are in the Biodance mask?

The gel masks are soaked in a serum that is made up of three ingredients. The first ingredient is ceramides. Your skin naturally has ceramides in it, but if those natural levels drop, it can cause skin to get dry and rough. Experts have previously told us that skin care containing this ingredient can add moisture back into your skin barrier.

Another of the ingredients in the serum is panthenol, which is another name for vitamin B5, which is known to be anti-inflammatory, according to Biodance. It also contains hyaluronic acid, which experts have told us acts like a magnet to draw more water into the skin. Finally, the serum contains glacier water — which is hydrating but also naturally contains minerals that the brand says can nourish skin.

The mask is intended to be worn as you sleep to allow the serum to soak into the skin for as long as possible. It comes in two parts — a piece for everything above your nose and below. This allows you to get a better, smoother fit.

Is the Biodance mask worth it?

As for whether or not Biodance Hydro Cera-nol Real Deep Face Mask is worth it, you get four masks for just under $20 — so each mask comes out to about $5. The mask set has a 4.3-star average rating from 12,996 reviews on Amazon and reviewers say they have noticed increased hydration and glow after using the mask.

In addition to Biodance Hydro Cera-nol Real Deep Face Mask, the brand’s Collagen Real Deep mask is popular and has had its own viral moment on TikTok. According to the brand, that mask can help with skin elasticity and firmness.
