Why does lotion foam so much? It is normal to have foam

When shaking lotion, you will find that there will be some foam, and some lotions have particularly much foam. So what is the reason why lotion has so much foam? Let’s find out together.

What causes lotion foam?

Because the surfactants in the lotion are reacting, bubbles will be produced when the lotion is shaken. Cleansing lotions contain saponin ingredients, which can produce bubbles like soap; high-concentration moisturizing lotions contain molecular glue, which is so sticky that it produces foam.

How good is the lotion foam?

If the bubbles produced by shaking the lotion are not only numerous but also very fine and last for a long time, it means that the lotion contains more nutrients. It is a relatively good toner, but if a lot of bubbles are produced, it means that the toner contains salicylic acid. Although salicylic acid has a good cleansing effect, it is quite irritating. Girls who are allergic to salicylic acid or have very sensitive skin should try not to use it.

Why does lotion foam so much?

The surfactants in toner react with water to produce white foam. It may also be because you did not wash your face thoroughly, and when you use toner for secondary cleansing, all the facial cleanser residues remaining in the pores of the skin are cleaned out and float to the surface of the pores.

How to use lotion

First, dip a cotton pad in toner and pat it on your face. Gently pat your face and neck from inside to outside and from bottom to top.
