Biodance Bio-Collagen Real Deep Mask Review UK

Verdict

A hydrating hydrogel mask with glycerin, niacinamide, betaine and hyaluronic acid in a close-fitting gel. It suits a temporary hydration boost and a smoother-looking finish. It is not a way to rebuild collagen: the brand's absorption and collagen claims are its own, and we found no independent study of this finished mask.

Best for

Dehydrated-feeling skin that wants an occasional hydration boost, or a pre-event treat.

Less suitable for

Congested or acne-prone skin during long overnight wear, active eczema or rosacea flares, and vegans (collagen is listed).

Who this suits

Biodance Bio-Collagen Real Deep Mask is a sheet mask supplied in a 34g size in box of 4 single-use masks, 34 g each. Texture: Jelly-like hydrogel sheet in two parts (upper and lower face). On the formulation we hold, it is best suited to dehydrated-feeling skin that wants an occasional hydration boost, or a pre-event treat. It is less suitable for congested or acne-prone skin during long overnight wear, active eczema or rosacea flares, and vegans (collagen is listed). Manufacturer usage guidance: Overnight: apply at the end of your skincare routine and remove the next morning. Daytime: after toner or serum, leave on for 3-4 hours or until the mask becomes transparent. The eye and mouth cut-outs can be placed on the sides of the nose, under the eyes or on the neck.

Biodance Bio-Collagen Real Deep Mask: what to expect

By the Korean PDRN editorial team · research-based, not a hands-on test · Updated 30/10/2026

This is the mask most of the hydrogel conversation is about. The formula is mostly water, glycerin and gel-formers, with niacinamide high in the list and collagen extract and hydrolysed hyaluronic acid further down.

The gel holds water and essence against the skin, which is why skin looks plumper straight afterwards. That effect is temporary, and a mask turning clear does not show how much has been absorbed.
