Sometimes I think I spend too much time on TikTok, but then I get recommended products like the Biodance collagen mask, and I suddenly feel like my aimless scrolling was worth it. For weeks, I stumbled upon videos of girls applying some creamy-white sheet mask to their face on flights. Fast-forward to landing and the mask has become completely transparent.

Akin to a snake shedding its skin, the TikToker would peel the finished mask from their face to reveal a bouncy, glowing complexion. Initially, I considered the mask superfluous – something akin to the word for those trying to make an in-flight skin-care routine happen, as opposed to it being an actually effective product. Then, one day, I couldn’t take it anymore and placed an Amazon order at an ungodly hour.

Perhaps an overnight collagen sheet mask was worth exploring after all. Most people are likely well aware of the benefits of collagen in skincare. “Collagen is really critical to our health because it makes up 30 per cent of all of the protein in our bodies,” Josh Axe, DNM, a clinical nutritionist, previously told my colleague, beauty editor at-large Arden Fanning Andrews.

He went on to say that, because our collagen reserves decline around age 25, anyone looking to replenish those reserves is to consume it via . While I’ve seen improvements in my skin and hair growth when using elixirs by Vital Proteins and Hum Nutrition, I hadn’t considered applying collagen topically – and, if I’m honest, I wasn’t.
