Amino Acids Help Keep You Beautiful
Amino acids are a natural skin moisturizer!
Collagen is made from amino acids.
Amino acids are gentle on your skin and hair.
Many products such as shampoos, conditioners and body washes advertise that they contain amino acids. Products formulated with amino acids offer a number of benefits.
Amino acids are also used for a healthy diet and exercise. Women are increasingly using amino acids for their many benefits.
Our bodies are about 60% water. That means that a person who weighs 50 kilograms (110 pounds) has about 30 kilograms (66 pounds) of water in their body.
Skin is important for retaining this moisture. Skin contains a layer of subcutaneous tissue that is protected by a 2–3 mm layer of dermis. The dermis is covered by a 0.1–0.2 mm layer of epidermis. This is in turn protected by an outermost skin layer called the stratum corneum, which is just 0.01–0.02 mm thick.
The layers of skin from the epidermis and below are made of live cells but the cells in the epidermis die in about two weeks. These cells are pushed out to the surface of the skin and become the stratum corneum. The stratum corneum is eventually shed off, which is called turnover. The amount of moisture retained by the stratum corneum greatly affects how moist our skin feels.
Amino acids are critical to the natural moisturizing factor (NMF) of the stratum corneum.
When the cells in the epidermis die and become the stratum corneum, the proteins in these cells are broken down into amino acids and supplied to the stratum corneum.
Roughly half of the NMF of skin is amino acids and pyrrolidone carboxylic acid (PCA). PCA comes from the amino acid glutamate.

Collagen is recognized as a beauty ingredient that gives skin its firmness and elasticity. Collagen is actually made from various amino acids (see diagram).
Moisture retention is just as important for hair as it is for skin.
The cuticle is the outermost part of the hair and plays an important role in retaining moisture. The amino acids in cuticles work to retain moisture.
Dull and dry hair is a sign of severe cuticle damage and a lack of amino acids. More people are dyeing their hair nowadays but coloring agents and bleach can damage hair and the cuticles in particular. Using shampoos, conditioners and treatments that contain certain amino acids helps promote moisture retention and keep hair from breaking. Amino acid care helps give you smooth and silky hair.
Soaps, cosmetics and hair care products made with amino acids are hypoallergenic and gentle on your skin and hair.
If you wash your hands with normal soap 10 times, once every 20 minutes, your hands will become dry and rough.
If you instead wash your hands with an amino acid-based surfactant, your hands will experience almost no dryness or roughness. Much of this is due to the pH level of skin. Skin is naturally somewhat acidic with a pH of 5 to 6. Washing your hands repeatedly with alkaline soap increases the alkalinity of your skin. This is the main reason why soap causes rough skin.
Amino acid-based soaps and detergents clean your skin while maintaining natural pH levels.
Recently there has been a lot of interest in using amino acids in sports and exercise to promote fat burning.
Muscles contain abundant amino acids.Supplementation with amino acids during aerobic exercise such as running or long-distance swimming helps the body to rebuild new muscle. As you build up your muscle mass, your body uses more energy because the metabolic rate increases. This makes it harder to gain fat.
Taking amino acids helps you to exercise more efficiently, for longer and at greater capacity. This helps your body to burn more fat.
More people today are taking amino acids to stay lean, from athletes to the health-conscious.
Amino Acids—Environmentally Friendly
Soaps and detergents are flushed down with household wastewater. Ideally they should be biodegradable so they rapidly decompose into the environment.
Biodegradable ingredients are environmentally friendly. Even if these products are released into rivers and lakes they can be broken down by microorganisms into carbon dioxide and water. Since amino acids are building blocks of living things, they are readily broken down in nature. Many popular detergents nowadays are made by binding amino acids such as glutamate and glycine to fatty acids.
Amino acid-based products are increasingly used in our everyday lives.
