Synthetic surfactant is at risk.

Most of the cosmetics sold include  synthetic surfactant. This is used to emulsify oil and water. Since it is lower cost, strong power to emulsify, and stabilizes, many companies use this.

But, many disadvantages...

- Absorbs necessary natural oils.

- Destroy natural skin barrier, so that active ingredients penetrate deeper, but at the same time unnecessary other chemical stuff is also penetrated deeper.

- Broken skin barrier cannot keep moisture inside, so you get drier skin.

- The longer you use it, the weaker your skin becomes.

- There is possibility to dissolve intercellular lipid, and damage protein in skin, like collagen.

If it is used as cleansing item,

- It is hard to get rid of this, so it stays on the skin.

- Inhabitant on the skin, which controls skin's health condition, is rinsed away.

in general, it is said that cleansing oil has the most % of synthetic surfactant.
