Description
When skin feels dry, tight or just tired, a sheet mask is one of the easiest ways to give it a concentrated drink. Round Lab’s Birch Juice Moisturizing Mask brings the line’s signature ingredient, birch sap from Inje (listed at 9,900 ppm), into a soft cotton sheet soaked in a light, watery essence. The brand describes it as a deeply hydrating mask for dry, tired-looking skin, designed to leave the complexion refreshed and comfortable.
The essence also includes sodium hyaluronate for moisture, allantoin and dipotassium glycyrrhizate for a calm feel, and caffeine, which the brand includes for a fresher, less puffy look.
Key ingredients
- Birch (Betula platyphylla japonica) juice – the Birch Juice line’s hero ingredient.
- Sodium hyaluronate and glycerin – for hydration.
- Allantoin and dipotassium glycyrrhizate – comforting ingredients.
- Caffeine – for a refreshed look.
How to use
- Cleanse your face and apply toner.
- Unfold the mask and place it evenly on the face, aligning eyes and mouth.
- Leave on for about 10 minutes.
- Remove and gently pat the remaining essence into the skin. Follow with moisturizer if you like.
Who it suits
Aimed at dry and tired-looking skin, it also suits normal and combination skin as a weekly or pre-event hydration step.
Good to know
Pack of 10 single-use sheets. Do not leave the sheet on until it dries out, and do not reuse a mask.
As with any new skincare product, patch-test on a small area (for example behind the ear or along the jaw) for 24–48 hours before using it on the whole face. Stop using it if redness, itching or stinging persists, and avoid applying it to broken or irritated skin. Always check the full ingredient list on the packaging you receive, as formulas can be updated by the brand.
