Proline

* An amino-acid * Can also be found as L-proline, D-proline, or DL-proline

Proline is one of the twenty non-essential amino acids, meaning that it can be created and synthesized within the human body. It is involved in the body's production of collagen and cartilage (and is often seen as an ingredient in energy drinks and dietary supplements) and is used in anti-aging and cosmetic formulas because of its ability to strengthen and renew aging skin cells. One-sixth of collagen, a major building block of skin (and its youthful appearance) is comprised of proline (Wikipedia). According to research, Proline can break down protein to help create healthy cells and connective tissues, promoting firmer, glowing skin and reducing sagging, wrinkles and aging of skin due to sun exposure.

Functions:

Proline is one of the twenty non-essential amino acids, meaning that it can be created and synthesized within the human body. It is involved in the body's production of collagen and cartilage (and is often seen as an ingredient in energy drinks and dietary supplements) and is used in anti-aging and cosmetic formulas because of its ability to strengthen and renew aging skin cells. One-sixth of collagen, a major building block of skin (and its youthful appearance) is comprised of proline (Wikipedia). According to research, Proline can break down protein to help create healthy cells and connective tissues, promoting firmer, glowing skin and reducing sagging, wrinkles and aging of skin due to sun exposure.

Proline is seen in cosmetics and beauty products primarily as a hair and skin conditioning agent, but also as a fragrance ingredient. It can also be used in formulas to act as a moisturizer when mixed with water. Proline has also been used in hair trials as one of four amino acids to help strengthen the hair shaft.

Safety Measures/Side Effects:

According to the Cosmetics Database, Proline is considered a low hazard ingredient. The only concern noted is the potential for Proline to be a carcinogenic; studies in 1996 found that in vitro tests on mammalian cells showed positive mutation results. No other negative side effects were found reported for Proline, and when taken as a supplement, there are no known negative side effects to proline, except for a slight upset stomach. As L-proline, it is FDA approved.
