Sheet masks are probably the easiest way to try a Korean skincare brand without committing to a full-size bottle. Round Lab's Soybean Nourishing Sheet Mask is a single cream-type mask priced as a low-risk sample of the brand's soybean line.
What Round Lab says about it
According to Round Lab, this is a cream-type sheet mask with an essence built around black soybean extract, ceramide and adenosine. The brand describes it as supplying dense nourishment for a firmer-looking complexion, calming sensitive skin and adding moisture to skin that feels dry and rough.
- Black soybean extract: Round Lab says it uses black soybeans grown in Jeonseon (as spelled on the page), Korea. The ingredient list shows Glycine Max (Soybean) Seed Extract at 1,000ppm.
- Ceramide: Ceramide NP is listed as an active ingredient, alongside cholesterol and sphingolipids in the full list. The brand says ceramide calms irritated skin and cares for dry, rough skin.
- Adenosine: included in the essence; Round Lab markets the mask with anti-aging and firming language.
- Other listed actives: glycine, Althaea Rosea (hollyhock) flower extract and caffeine.
- Sheet: a soft microfiber sheet that, per the brand, adheres lightly to the skin.
Each mask holds 0.9 fl. oz (27ml) and it is unscented.
One note: the product page also includes a few lines about surfactants and "plant derived oil" for gentle cleansing, which read like they belong to a cleanser. We have left those out here, since a sheet mask is not a cleanser; check the brand page if that detail matters to you.
Where it fits in a routine
Round Lab's directions are clear and follow the classic K-beauty order:
- Cleanse your face.
- Use a toner to prep the skin.
- Take the mask out of the pouch and place it evenly on your face, lining up the eyes, nose and lips.
- Remove it after 20 minutes and gently tap in the remaining essence until absorbed.
After that, you can follow with your usual cream to seal things in. Because it is a cream-type mask, it suits a slower evening routine, for example winding down after a long concert day or before a comeback stream.
Who it might suit
The page does not list specific skin types, but Round Lab's description points at skin that feels dry, rough or stressed and wants extra nourishment. Since Round Lab frames this mask around nourishment, it is a low-cost way to see whether you like that line before buying a larger product from it.
What to check before you buy
- Patch test: a sheet mask covers your whole face for 20 minutes, so test a little essence on your jaw or inner arm first.
- Allergies: the formula contains soybean extract. If you react to soy, read the full ingredient list carefully.
- Price and shipping: it is listed at $4.00 per mask on Round Lab's US store at the time of writing. For a single mask, shipping can cost more than the product, so check shipping to your country and the current price on the brand page, and consider adding it to a larger order.
Our take
The Soybean Nourishing Sheet Mask looks like a simple, inexpensive add-on: one 27ml cream-type mask with soybean extract, ceramide and adenosine, used for 20 minutes after toner. It makes the most sense as a treat for a dry-feeling evening or as a way to sample Round Lab's soybean line. Patch-test first and keep your expectations to what a single mask can do.
