Why are amino acids so popular?

Why do many toiletries and skin care products like to add amino acids?

Because it's really great!

The amino acid ingredients in cosmetics can activate cells, improve metabolism and blood circulation, revitalize the skin, and say goodbye to dullness. Its efficient moisturizing function can replenish skin moisture according to the season and keep it hydrated and moisturized.

The specific features and functions are as follows:

1. Moisturizing effect

Amino acids have a moisturizing effect. They are better at retaining moisture than any natural or synthetic polymers, and their moisturizing performance is 12 times that of glycerol. As a component of moisturizers, amino acids contain a positive electrode and a negative electrode in their molecular structure. The positive and negative electrodes can capture a molecule of water to form a thin film on the skin surface. On the one hand, it seals the water in the skin to prevent water evaporation, and on the other hand, it does not hinder the skin's absorption of air moisture, thereby maintaining the skin's proper humidity.

2. pH close to human body value

Take amino acid washing and care as an example. Amino acid washing and care uses weakly acidic amino acid surfactants. The pH value is close to that of human skin, basically maintained between 5.5-6.5. In addition, amino acids are the basic substances that constitute protein, so they are gentle and skin-friendly. They are not only suitable for acne skin, but also one of the few shower gel cleaning products that can be used with confidence for sensitive skin. Traditional shower gel washing and care products focus on efficient cleaning, blackhead removal, oil removal, etc., but ignore the stimulation of the product itself to the skin. In order to improve the cleaning power and oil removal ability, highly alkaline surfactants, foaming agents, soap bases and other ingredients are added, while human skin is weakly acidic, and long-term use will irritate the skin. What's more serious is that the sebum membrane of the skin will also be destroyed. Once the sebum membrane is lost, the skin is easily damaged by the outside world.

3. Anti-allergic

Amino acids can not only reduce the impact of harmful substances in the environment on the skin, but also enhance the skin's anti-allergic ability and expel aging cells, oils and other waste substances.

4. Antioxidant property

Amino acids can also regulate skin moisture, balance skin oil, and increase skin immunity. They can reduce or prevent oxidative damage to the skin, and also reduce aging caused by sunlight. They have a very good effect on skin renewal, repair, and avoiding dehydration.

5. Delaying skin aging

Amino acids can activate the antioxidant activity of skin cells and remove excess free radicals in cells, thereby preventing wrinkles and delaying skin aging. It has a better transparent effect than general hyaluronic acid, which can smooth dry lines, strengthen skin defense function and protect skin, and prevent and improve skin dryness to avoid damage caused by changes in the external environment.
