Proteins are the basic building blocks of life and can be found at the microscopic level in our cells and at the macroscopic level in our skin and other organs. Proteins play an important role in the health and functioning of our bodies and must be consumed on a daily basis so that we can perform well. Amino acids can be considered an even more fundamental building block because they are the organic units the makeup proteins themselves. About 500 mino acids have been discovered in nature with only 20 found to play a significant role in the human body. Because proteins and amino acids play a critical role in skin health, many aesthetic and cosmetic products claim to boost the body’s production of them.
