If you have been following K-beauty through your favourite idols' vlogs, you have probably noticed how often a sheet mask shows up at the end of a long day. Round Lab's Soybean Panthenol Sheet Mask is one of the brand's single-sheet options, and it is also one of the most affordable ways to try its Soybean Panthenol line, which Round Lab positions around the skin barrier. This guide sticks to what the brand itself says.
What Round Lab says about it
According to Round Lab, this is a deeply hydrating microfiber sheet mask infused with nourishing black bean essence. The brand describes the sheets as biodegradable and says they adhere closely to the skin to deliver moisturising panthenol, ceramides and nutrients.
So the three things to remember from the product page are:
- Black bean (soybean) essence – the signature ingredient of the Soybean line, which Round Lab describes as nourishing.
- Panthenol and ceramides – listed by Round Lab as the moisturising components delivered by the sheet.
- A biodegradable microfiber sheet – the brand highlights a close-fitting sheet that is designed to be biodegradable.
It is listed at $3.99 on Round Lab's US store at the time of writing. That is the price for a single sheet, so it works well as a low-commitment trial before buying a multi-pack or a full-size Soybean product. Please check shipping to your country and the current price on the brand page, because both can change.
Where it fits in a routine
A typical K-beauty routine runs cleanse → toner → serum → cream → sunscreen (sunscreen in the morning only). A sheet mask usually slots in right after toner, in place of or before your serum step. A simple evening order could look like this:
- Cleanse (a double cleanse if you wore sunscreen or makeup).
- Toner.
- Soybean Panthenol Sheet Mask – follow the timing printed on the pouch.
- Remove the sheet and gently pat any leftover essence into the skin.
- Your usual cream to finish.
Who it might suit
Based on how Round Lab describes it, this mask may appeal to people looking for a hydrating, barrier-focused step, and to anyone curious about the Soybean Panthenol line who wants to try it before committing to a bigger product. The biodegradable sheet is also a point of interest if you care about what goes into the bin after your skincare.
The product page snippet we collected does not list a specific skin type, so we will not claim it suits everyone. If you have sensitive or reactive skin, read the full ingredient list on the brand page first.
What to check before you buy
- Full ingredient list: look for anything you know you react to.
- Patch test: try a little of the essence on your inner arm or jawline and wait a day before using the full sheet.
- Usage time: follow the pouch instructions rather than leaving the sheet on until it dries.
- Shipping: a single low-priced sheet can be outweighed by shipping costs, so check whether bundling with other items makes more sense for your country.
Our take
We have not tried this mask, so this is not a review. On paper, Round Lab's Soybean Panthenol Sheet Mask is a straightforward, inexpensive way to sample the brand's barrier-focused Soybean line: black bean essence, panthenol and ceramides on a biodegradable sheet, according to Round Lab. If you are building a K-beauty routine inspired by your favourite K-pop artists and want an easy night-time extra, it is a sensible single sheet to read up on. Just patch test, follow the pouch timing and confirm the latest details on the brand page.
