Disadvantages of amino acid facial cleanser

Amino acid facial cleansers have become quite popular in recent years. Only with sufficient amino acids can people's bodies maintain good health, so an amino acid facial cleanser has been developed. Amino acid facial cleanser itself is a weak alkaline, but it may not be suitable for some skin types. When choosing a facial cleanser, you need to purchase it according to the nature of your skin to ensure the correct choice.

Amino acid facial cleanser is a new concept of facial cleanser that has appeared on Taobao in recent years. The cleaning ingredients used in traditional facial cleansers are all surfactants, and the amino acid surfactants among them are amino acid salts (sodium salt, potassium salt, triethanolamine salt) of coconut oil (or laurel oil or palm oil) (such as glutamic acid, glycine, etc.) with foaming and cleaning ability. Weakly acidic amino acid surfactants have a pH value close to that of human skin. In addition, amino acids are the basic substances that make up proteins, so they are gentle and skin-friendly, especially for sensitive skin.

Because it is highly alkaline, it is very irritating to the skin. Because amino acid facial cleansers use weakly acidic amino acid surfactants, they are gentle and skin-friendly, have little irritation, and can be used by children.

Amino acids themselves are weakly acidic, which just matches the acidity and alkalinity of the skin and will not affect the acidity and alkalinity of the skin.

As a surfactant, amino acids are less irritating to the skin, are particularly skin-friendly, and have moderate cleaning power.

There is no residue after use, which avoids the damage of residual substances to the skin's natural protective layer.

It can be used for a long time without any concerns about harming the skin.

A proper cleansing process is the first and most important step in skin care. Because our skin has a layer of oil secreted by the sebaceous glands, and this layer of oil is very easy to be contaminated by dust, and will oxidize and deteriorate after long-term contact with the air. Not only will it make the skin have an odor and look gray and dull, but it is also not good for the skin. Therefore, it is very important to maintain our skin by removing dust and deteriorated sebum every day.

Generally speaking, facial cleansing products are usually mainly alkaline soap products and cleansing products with surfactants as raw materials.

In terms of manufacturing principles, ordinary soap is made from a mixture of oil and sodium hydroxide, so soap is a strong alkaline cleaning product with a pH value of 9-10. The skin on the human face is normally weakly acidic. If you use a strong alkaline soap, it will change the acid-base environment on the skin surface, which will have a considerable negative impact on the skin's metabolism. In addition, the strong alkaline soap has a strong cleaning ability and can easily wash away the oil between skin cells, which is one of the important factors leading to dry skin - the harm of excessive cleaning is probably worse than not cleaning at all. Problems such as acne and allergies are often related to excessive cleaning.

Therefore, a better choice should be to use a cleansing product that is specially developed for skin cleansing and uses surfactants as raw materials.
