Sheet masks are one of the most fun parts of K-beauty, and a staple of idol self-care clips and K-drama night-in scenes. Round Lab's Mugwort Calming Sheet Mask comes in a pack of five, which is enough to try it as a weekly ritual for a little over a month. Here is what Round Lab says about it and how a sheet mask like this fits into an evening routine.
What Round Lab says about it
According to Round Lab, this mask is made with a pure cotton sheet soaked in clean, natural ingredients. The brand says the essence contains calming ingredients and that the mask is meant to soothe irritated-feeling skin.
Mugwort is a familiar name in Korean skincare, often used in products marketed for a calm, comfortable feel. Round Lab's best-known calming line is Pine Cica, so the Mugwort mask sits alongside it as another calming-focused option in the catalog, based on how the brand describes it.
The pack of five is listed at $19.00 on Round Lab's US store at the time of writing, which works out to about $3.80 per mask.
Where it fits in a routine
A sheet mask usually comes in the middle of an evening routine, after the toner and before your cream:
- Cleanse (double-cleanse if you wore makeup or sunscreen).
- Toner.
- Sheet mask, left on for the time Round Lab gives on the pack or product page.
- Remove the sheet and gently pat the remaining essence in.
- Seal with a moisturizer or cream.
Most people use sheet masks one to a few times a week rather than daily. With five masks, a once-a-week rhythm gives you about five weeks of "mask nights", which is a nice way to slow down after a long day of streaming comebacks.
Who it might suit
- People who want a calming-focused sheet mask, as Round Lab describes it.
- Anyone who prefers a cotton sheet over hydrogel or gel-type masks.
- K-beauty fans building a weekly self-care night, or looking for an easy small gift.
What to check before you buy
- Patch test: mugwort is a plant-based ingredient, and plant extracts can bother some people. Try a small amount of the essence on your inner arm or jawline first.
- Ingredients: read the full ingredient list on Round Lab's page if you have known allergies or sensitivities.
- Expectations: a sheet mask is a cosmetic product, not a treatment. If your skin is persistently irritated, see a dermatologist.
- Shipping and price: check whether Round Lab's US store ships to your country, what shipping costs, and the current price on the brand page.

Our take
We have not tried this mask, so this is based only on Round Lab's description. As described, the Mugwort Calming Sheet Mask is a simple, cotton-sheet option for people who want a calm-feeling mask night, and the five-pack keeps the price per sheet reasonable. If you like mugwort products or want to build a weekly masking habit, it is worth a look. Patch-test it first, and pair it with a gentle moisturizer afterwards.
