The Indispensable Amino Acids
Amino acids are the building blocks for proteins and peptides. They maintain the resilience, texture and the healthy and supple appearance of the skin. There are less than twenty amino acids considered important for the skin.
These are either non-essential or essential amino acids. Your body can make non-essential amino acids. Essential amino acids must be obtained through supplements or foods.
The nine essential amino acids are valine, phenylalanine, histidine, tryptophan, leucine, methionine, isoleucine, threonine and lysine. The best food sources include animal protein such as poultry, beef, and seafood.
The second best sources are animal by-products including dairy and eggs. Vegans receive amino acids through tofu, soy, and quinoa. Some amino acid can be gained by consuming nuts and beans.
There are eleven important non-essential amino acids. Your body can produce them without any additional sources. Every amino acid has an important role in the appearance of your skin. If your body does not have enough amino acids, your skin can become loose and appear as dull, rough and lackluster.
Amino Acids for Skin Tightening
Amino acids are natural to your skin. They are referred to as natural moisturizing factors or NMF's. The amino acids work within the upper layers of your skin as conductors. They are responsible for a complex process enabling your skin to remain tight, stay hydrated and thrive.
The amino acids work in conjunction with the water transportation system of your body. This is called the aquaporins. This system moves the moisture throughout your skin. The main benefits are tight, smooth and well-hydrated skin.
Many individuals try to obtain these benefits through skin care products. Amino acids are small but incredibly potent. Some of them are able to function as antioxidants.
One of the surprising benefits of amino acids is they help your skin create more natural antioxidants including glutathione. When you apply topical antioxidants to your skin, they will strengthen the natural defense system of your skin.
This means your skin can effectively fight off damage from the environment and will not show nearly as many signs of aging.
Once the amino acids in your body have been replaced, your skin will appear tighter, more youthful and smoother.
Research has demonstrated synthetic amino acids usually possess a greater ability for hydration than amino acids derived from plants or animals. This is good news if you would prefer to receive synthetic amino acids as opposed to getting them from animals.
