How long can a bottle of facial cleanser last?

Of course, the answer is not fixed. It depends on how big your facial cleanser is and how much you use it every day. So the point of this question is: How much facial cleanser is needed to clean your face?

This mainly depends on the following two aspects:

The more powerful the facial cleanser, the less you should use.

Everyone knows that there are two types of facial cleansers on the market:

1. Soap base

2. Amino Acids

The cleaning power of soap-based products is much stronger than that of amino acids , so the amount of soap-based facial cleansers used should be less than that of amino acids.

However, because soap-based cleaning power is too strong and can easily damage the skin, it is recommended that you use a more gentle and cleansing amino acid facial cleanser .

Generally speaking, a peanut-sized amount of amino acid facial cleanser is enough. If you use a foaming net or foaming ball , you can increase the amount appropriately because there will usually be residue. I basically use double the amount.

The oilier your skin is, the more you should use.

The cleansing principle of facial cleanser is that the active ingredients (surfactants) combine with the oil on the skin to pull the oil off the skin and achieve the cleansing effect. So the more oil there is on your skin, the more facial cleanser you will need.

People with dry skin can reduce the amount of facial cleanser used to reduce the damage to the sebum film. For oily skin , you can increase the amount on the wings of the nose, forehead and chin to ensure thorough cleaning.

In addition, the degree of oil production varies from day to day , so you don’t need to use the same amount every day. You need to learn to adjust .

For example, if the oil secretion is strong during menstruation, you can use more facial cleanser appropriately; or if the pressure before an exam causes excessive oil secretion, or if you stay up late at night during the holidays causes excessive oil secretion, you need to increase the amount of facial cleanser appropriately.
