Why is there foam when toner is applied on the face? Is white foam good?

Toner is familiar to many people. It can be used on the face and has a moisturizing effect. So why does toner produce foam when applied to the face? Is it good to have white foam formed when toner is applied on the face?

Why does toner produce foam when applied to the face?

This is because of some surfactants in the lotion.

Usually, lotion is not completely made up of water-soluble substances. In order to dissolve fragrances and some oil-soluble ingredients in it and maintain a transparent appearance, surfactants need to be added. Some negative factors brought about by this ingredient are that when you shake the lotion vigorously, there will be a layer of foam on the surface of the water after you stop. The greater the force you use and the longer you shake it, the more foam there will be. When you use toner, the application process is like shaking water vigorously, so some small bubbles will be produced on the skin surface. Usually, you can avoid this situation by patting water with a cotton pad.

As for whether these bubbles have an impact on the skin, it depends on the specific product. Some ingredients will harm the skin, but some are caused by the protein ingredients in the lotion that produce bubbles. The protein component is also a surfactant component, just like if eggs are beaten for a long time, foam will appear on the surface.

Is it okay to apply toner on your face and cause white foam?

The first situation is that you don't clean thoroughly, and the friction between water and debris on the skin causes foaming.

The second situation is that your water has a high chemical composition, which cannot be absorbed by the skin and forms foam on the surface of the skin.

The third situation is that your water is not pure enough (for example, water purchased online usually contains added purified water or other liquids), which results in the water not being absorbed by the skin when applied to the skin and instead forming dirt on the skin. Long term use will clog the pores.

That’s all about the white foam when toner is applied on the face. Now you know the common sense, right?
