What is Sarcosine?
Sarcosine, also known as Glycine, N-methyl-, is an amino acid derivative that is commonly used in cosmetic products for its skin conditioning properties. Chemically, it is a methylated form of the amino acid glycine, which means it has a methyl group attached to the nitrogen atom of glycine. This small modification makes a significant difference in its functionality and application in skincare.
Historically, sarcosine was first identified in muscle tissue and has since been studied for various biological roles. Its journey into the cosmetic industry began when researchers discovered its ability to enhance the skin’s texture and appearance. Over time, it has become a popular ingredient in a variety of skincare formulations, from moisturizers to anti-aging creams.
Sarcosine is typically produced through a synthetic process that involves the methylation of glycine. This is achieved by reacting glycine with formaldehyde and a reducing agent, usually sodium cyanoborohydride. The result is a stable compound that can be easily incorporated into cosmetic products to improve their efficacy.
The Benefits/Uses of Sarcosine
In this section, we will delve into the officially recognized cosmetic benefits and uses of Sarcosine:
Skin Conditioning
Sarcosine is primarily known for its skin conditioning properties. This means it helps to maintain the skin’s softness, smoothness, and overall health. When included in cosmetic formulations, Sarcosine can enhance the texture and appearance of the skin, making it feel more supple and hydrated. This is particularly beneficial for those with dry or rough skin, as it can help to restore a more youthful and vibrant look.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Potential Side Effects & Other Considerations
Sarcosine, also known as Glycine, N-methyl-, is generally considered safe for topical application in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
- Skin irritation
- Allergic reactions
- Redness
- Itching
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Sarcosine during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Sarcosine are relatively uncommon, but they can occur. It is recommended to conduct a patch test before widespread usage to ensure that you do not have an adverse reaction to the ingredient.
In terms of comedogenicity, Sarcosine has a rating of 0 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This means that Sarcosine is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts.
