The Hada Labo Masks review continues with the Shirojyun Mask (middle picture).
Arbutin is the main ingredient separating this mask from her sisters. Arbutin is essentially extracted hydroquinone from botanical sources, so if you are allergic/has some reaction to hydroquinone, you may want to avoid this, although I suspect at this concentration and for occasional use, it is extremely low. The second whitening ingredients is the Magnesium Ascorbyl Phosphate, which is really down below the list. Just think about it.. if the alcohol represents 1% weight/weight, imagine how minute is the amount of the MAP in this mask. In short, I don't think this mask will give an instant whitening effect, but it has the "potential" due to these two ingredients.
The 1% w/w alcohol content did not sting, tingle or burn. I wave this mask about for a bit before putting it on my face to evaporate some of the alcohol. Not much, just some.
- Consistency similar to Gokujyun above, it almost came out dripping from the pouch.
- Slight cooling sensation due to the alcohol, but it dissipate quickly. I fan the mask about before putting it on my face.
- It does not tingle, sting or burn.
- No noticeable whitening effect from once a week use for a month -- maybe need to use this longer/more often?
Between this Shirojyun and Gokujyun, I'm still on the look out for a better Hada Labo mask. I will safe the best one for last, on the next post.
