SOME BY MI Yuja Niacin 30 Days Care Serum Mask × 10
A Brightening Sheet Mask with Niacinamide, Arbutin, Vitamin C & Glutathione
A brightening sheet-mask treatment designed for dullness, uneven-looking skin tone, post-blemish marks and dehydration.
Each mask delivers an essence built around niacinamide and yuja (Citrus junos) extract, with additional support from arbutin, a vitamin C derivative, glutathione, panthenol and multiple forms of hyaluronic acid.
Unlike a daily serum or cream, this mask gives practitioners an occasional intensive hydration and brightening step within the Glass Ritual Pigmentation Collection.
Why We Chose It
We chose the SOME BY MI Yuja Niacin Serum Mask because pigmentation routines do not need to consist entirely of concentrated daily treatments.
This mask combines several useful tone-supporting ingredients—niacinamide, arbutin, 3-O-ethyl ascorbic acid and glutathione—within a hydrating sheet-mask format.
That gives it a different role from the collection’s serums, pads and creams. It can provide an occasional brightening + hydration ritual without adding another permanent treatment layer to every morning and evening routine.
It is also described by the manufacturer as a vegan-certified sheet mask.

Who It's For
Consider these masks if you are concerned about:
- Dull-looking skin
- Uneven skin tone
- Post-blemish marks
- Dehydration
- Loss of radiance
- Adding occasional brightening care to an existing routine
- Wanting a hydrating treatment alongside pigmentation-focused ingredients
The formula does contain citrus peel oils and other aromatic plant oils, as well as limonene and geraniol. Practitioners with fragrance-sensitive or highly reactive skin should take this into consideration.
How to Use
After cleansing, apply your toner if desired. Place the sheet mask over the face and adjust it to fit comfortably. Leave on for 10–20 minutes, following the manufacturer’s directions. Remove the mask and gently pat the remaining essence into the skin until absorbed. Follow with moisturiser if additional moisture is needed.
Do not leave a sheet mask on until it becomes completely dry.
Ritual Position
Cleanse → Tone → Yuja Niacin Serum Mask → Moisturise
Use as an occasional treatment step within your Glass Ritual rather than assuming it must be used every day because of the product’s “30 Days Care” name.
Glass Ritual Pairing
Because the mask already contains niacinamide + arbutin + vitamin C derivative + glutathione, you do not need to turn mask night into an intensive active-layering session.
A simple ritual may be:
Gentle Cleanser → Toner → Yuja Niacin Mask → Moisturiser
If your skin is already receiving strong acids, retinoids or concentrated pigmentation treatments, keeping the rest of the mask ritual simple may be preferable.
Glass Ritual Principle: A treatment can be a moment of support—not another opportunity to overload the skin.
