I tested and I am dubious on the usefulness.

The mask sheet is hydrating. The tissu is of quality. The quantity of serum on the tissu is good. The serum doesn't sting but I don't know if the VB serum is efficient or not. I don't understand its usefulness. I'm tested the effector serum formula10 with the same opinion. Perhaps I must use this mask sheet several times to see a result.

The quatity of serum of step 1 is enormous. There are enough serum for 3 maybe 4 uses.

The only time it'll be painful is when you apply the product to close to your hair line, otherwise it's not as painful as people make it seem like. Makes your skin feel smooth after taking it off.

Where should I begin... such a wonderful moisturizing toner. I love it! Don't waste the product on a cotton pad! Just pour some in your palm and press it in your skin! I have been using it for the 7 skin method and it has been working wonderfully. My skin absorbs it in seconds. Not to mention it smells wonderful. The packaging looks luxurious. I would definitely repurchase and recommend.

It makes my skin smooth and moistened.

I used it everyday and my skin love it!

It sooth my skin super like it!

My skin didn't like it!

Love it!

Not so satisfied, it bring my lashes down.

Gentle to the skin. I love it!

I have a very sensitive skin so I can't just use any toner or sometime I prefer not to use toner to prevent breakouts but when I used this my skin is smooth and no breakouts at all. I like it!

These are good, they draw out all of the oil and resedue after popping a pimple.

This is not the best claymask I've used but it's good for the price.

This is good but the alcohol in it dries out my nose.

It leaves the skin smooth and brighten.
