Ingredient
Proline
What is Proline?
Proline is an amino acid that the body can produce naturally, meaning it's considered non-essential in dietary terms. It is a fundamental component of proteins, particularly collagen, which is the structural protein found in skin and connective tissues.
Proline is often used in cosmetic products for its supposed benefits to skin health. In supplements and food products, it may be included as part of a protein blend or for its structural role in proteins. While there is some evidence suggesting that proline may aid in skin health and wound healing, the overall research is still evolving.
When you see proline on a label, it typically indicates its use as a component of protein blends or as a targeted nutrient in skin-care products. It's generally well-tolerated in foods and cosmetics.
Commonly found in: supplements, makeup, skin-care products, protein bars, nutritional beverages
