ma:nyo Micro Hyaluronic Essence Mask is a vegan bamboo sheet mask built on 379Da ultra-low molecular hyaluronic acid — ten masks of concentrated hydration for dry, thirsty skin.
379 daltons — what the number means
Daltons measure molecular weight. Standard hyaluronic acid can run into the millions; at 379Da this one is extremely low-molecular. It’s a specific technical choice rather than a marketing number.
Why molecular weight matters
Larger molecules hold water at the very surface; smaller ones distribute more evenly through the upper layers. Neither is inherently better — which is why formulas often combine sizes, and why a mask focused on one size is a deliberate decision.
Enzyme extraction for selective separation
The production method separates hyaluronic acid molecules by size, so the formula can target a specific molecular weight rather than working with a broad, uncontrolled mix.
Ultra-thin bamboo sheet
Thin bamboo clings closely to facial contours instead of lifting at the nose and chin — which means more essence stays on your face rather than sliding down your neck.
Certified vegan ingredients
The brand states this mask uses certified vegan ingredients. Worth noting that ma:nyo’s wider catalogue is mixed, so vegan status applies per product rather than across the brand.
Fifteen to twenty minutes, then pat
Remove before the sheet dries out — once drying, it starts drawing moisture back out of the skin. Pat the remaining essence in and follow with moisturizer. Don’t rinse.
After cleansing and toner, unfold the mask over the face and smooth out air bubbles. Leave on for 15–20 minutes and remove before it dries. Pat the remaining essence into the skin and follow with moisturizer — do not rinse.
Daltons measure molecular weight. At 379Da this hyaluronic acid is extremely low-molecular — standard HA can run into the millions, so the difference in size is enormous.
Why does molecular weight matter?
Larger molecules hold water at the very surface; smaller ones distribute more evenly through the upper layers. Neither is better — which is why many formulas combine several sizes.
What is enzyme extraction?
A production method that separates hyaluronic acid molecules selectively by size, so the formula can target a specific molecular weight rather than a broad mix.
Is this mask vegan?
Yes — the brand states certified vegan ingredients. Note that ma:nyo’s wider range is mixed, so check individual products elsewhere.
Why a bamboo sheet?
Ultra-thin bamboo clings closely to facial contours, so more essence stays on your skin instead of lifting away at the nose and chin.
How long should I leave it on?
Fifteen to twenty minutes, removed before the sheet dries out. A drying sheet starts pulling moisture back out of the skin.
