Calling all experts! Does anyone know what amino acids do in skincare and how they work differently from AHA's, etc? I just received a bottle of the Bliss "Sleeping Peel Serum". It is described as an oil-free wrinkle-refining amino acid exfoiliating gel that promises to reduce pore size, fine lines and dull skin cells. I haven't used it long enough to tell if it delivers what it promises, but so far have had no bad side effects. I am just curious about amino acids, because I don't recall hearing about them in skincare before.
Thanks,
Sheisha |

sheisha,
I hate to burst your bubble (and someone please correct me if I'm wrong), but I think that any amino acid must be taken internally (orally) so that it can be properly metabolized and then converted into the proper protein strains to nourish the body. Usually amino acids (especially free form aminos) are very unstable and oxidize very quickly, and can break down.
This is just what I have read and remember from nutrition classes and skincare seminars.
I don't know that applying an amino acid topically would have the same or any effect on skin or hair.
What do the others think? |

| I've read that amino acids are the building blocks of protein (responsible for the synthesis of protein). Protein make up the bulk of cell structure and some serve as enzymes for catalyzing cellular reactions. I think when you apply topicals containing amino acids, they will give your skin cells the nutrients to nourish them and make them healthy. I don't know how they are going to reduce pore size, reduce fine lines and brighten the skin maybe. |

| Are you sure you don't mean amino-peptides? They are the hot thing in skin care right now. Mainly because they can be "engineered" to perform specific functions. For instance, "matrixyl" (palmitoyl pentapeptide)tricks your skin into thinking it needs to make more collagen so is good for thickening the skin. |

| The main ingrediant in the Sleeping Peel by BlissLabs is "Alpha Amino Acid" and the product also has "L-ascorbic acid", although it doesn't say at what %. Has anyone tried or heard about this product? It is very popular in the Bliss catalog and they also sell it at Sephora. |

| amino acids are small molecules that the body assembles into large complex structures called proteins. many hormones (growth hormone), neurotransmitters (serotonin), and structural components (keratin, collagen, elastin) are proteins made from various amino acids. Enzymes that allow important reactions to occur in the body are also made from amino acids. your body obtains most of its amino acids from diet, but it can also synthesize some of them on its own. you should try to obtain a legitimate study about this product that asserts it claims to do what it says. IMO, I doubt applying it topically will do anything. if it says the amino acids are in enzyme form, then that is the same as trying to push a large protein into the deep layers of skin. i don't think that will happen... ascorbic acid is just vitamin C (which, in terms of skincare, is plastered all over this forum), and alpha amino acid just designates some amino acid (there are many of them) with some other molecule hanging of the first carbon atom. I take amino acids orally in powder form. it helps a lot (i.e. glutathione, a potent antioxidant), especially for a diet that does not rely heavily on meat. |

I just did a search and I couldn't find any document that referenced the effects of amino acids ON the skin. I did find a very few off the wall no name products that touted them

Cellex-C's Skin Hydration Complex has amino acids in it. In their little blurb it just says "plus important skin benefitting amino acids"
