Q. Slow absorption? Minor effect?
A. The cause is dead skin cells and waste products that block absorption!
Clean the clogged skin from the ground up with PHA First Toner!

Real mild PHA peeling without AHA or BHA*
With PHA and fruit acid ingredients found in nature, daily keratin care is possible even for sensitive skin, which is burdensome to use AHA and BHA.*Completion of human application test for skin keratin improvement 

PHA found in nature, lactobionic acid
It is a naturally derived PHA found from lactose (milk sugar). Its particles are larger than AHA/BHA, so it reduces skin irritation while gently exfoliating and arranging the skin with a moist and smooth texture.
* Limited to the characteristics of raw materials

A weakly acidic peeling toner that my skin likes
The acidity of healthy skin is between pH 4.5 and 6.5.
Isoi PHA Toner has a slightly acidic formula similar to that of the skin, and it helps to balance damaged skin after washing and calms it down.

Keratin PHA Toner, if you use it, you will know
Hear reviews from people who have used it.

“Even after removing the dead skin cells, my face was flaky and my makeup was floating. We have won the battle against dead skin cells!
Highly recommended!”
Reviews by Kwon Jeong*

“Is it keratin pato? It's not irritating and it's just softer than a normal toner. There is no irritation so much that you doubt that the dead skin cells will be removed. But the effect is really great!
It's really reassuring to meet keratin pato."
Mun Choi*'s review

“I tried all the ingredients that contain Aha and Baha, but it was difficult to write because it was irritating and itchy. This is not such an ingredient, it is reassuring. Again, isoi is right.
The dead skin care is as good as I believed!”
Reviews from Da Jung*
