Amino acids are quickly becoming some of the most sought-after and talked-about ingredients in skin care. Ongoing research continues to uncover promising information about the many skin benefits of amino acids. They have the ability to efficiently penetrate the skin themselves and to also potentially increase the permeability of other important topical ingredients. Here is what the latest research says about amino acids and skin penetration.
Proven Effectiveness of Topically-Applied Amino Acids
Numerous studies have examined the many benefits of amino acids for the skin, including their vital role in collagen production, free radical protection, wound healing, and skin hydration. A growing body of evidence is in agreement that amino acids, especially when used in specific combinations, effectively penetrate the outer stratum corneum of the skin. There is still more research to be done to determine the exact mechanisms that allow this .
What we do know, however, is that the right combinations of topically-applied amino acids provide a vast range of benefits. While countless studies have proven the importance of amino acids in collagen production, one study published in Amino Acids concluded that amino acids are not only integral to the biosynthesis of collagen proteins, but they are also key components of the skin’s natural UV-defense system.
The results of this study found that when combined, branched-chain amino acids, arginine, glutamine, and proline had a significant effect on the restoration of collagen synthesis following UV irradiation . Interestingly, however, single amino acids did not have this same effect, indicating that a certain combination of amino acids is necessary.
Amino Acids as Permeation Enhancers
Amino acids may also prove to be beneficial ingredients to add to topical formulas in order to increase the permeability of other skin care ingredients. One study published in the Journal of Controlled Release investigated the effects of a peptide chain called L-Pro2, which consists of the amino acids proline, sarcosine, alanine, B-alanine, and glycine. Findings suggest that this particular combination of amino acids shows promise as a permeation enhancer, which could have profound implications for clinical use . It may help deliver topical medications that otherwise are not able to penetrate the stratum corneum.
Using Amino Acids in Skin Care
A growing body of research on the benefits of amino acids and peptides seems to suggest that the key is in finding the right combination to perform the desired functions. Therefore, when looking for amino acids in skin care products, find a formula that combines these ingredients rather than includes any single amino acid.
The AminoGenesis formula, for example, contains a blend of 17 plant-derived amino acids for optimum results. Therapeutic Facial Repair anti-aging moisturizing cream contains a higher concentration of amino acids than any other formula in the world. Use this excellent anti-aging cream to address a variety of skin concerns, including:
- Deep forehead lines
- The entire eye area, including fine lines, dark circles, and crow’s feet
- Deep smile lines around the mouth
- Sagging skin in the entire facial area
- Dull, dry-looking skin
- Stressed or sun damaged skin
Amino acids are turning out to be some of the most advanced and effective skin care ingredients currently available. While continued research is being done to uncover even more of their unique benefits and mechanisms, current research has already proven their essential role in a number of skin functions.
If you’ve been trying product after product and haven’t yet found a formula that yields the smooth, revitalized results you’re looking for, it may be time to give amino acid skin care a try.
