The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product. It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water. Expand to read more Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying. One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time. We don't have description for this ingredient yet. If you see a cosmetic product that claims that it has "Botox-like effect" then two things are almost certain: one, the product overpromises and two, it contains Argireline. So this one is the famous peptide that's marketed by its manufacturer as the "Botox in a jar". The basis for this claim is that it targets the same wrinkle forming mechanism (wrinkles caused by facial muscle movement) as Botox, but the way it works is very different. In addition, the extent to which it can prevent muscles from contracting (and to smooth wrinkles) is very different (otherwise why would anyone use still Botox?). The manufacturer did several studies to prove that Argireline really works and it does (just not as well as Botox). In-vivo (made on real people) tests showed that using 10% Argireline solution around the eyes for 15 days decreased wrinkles depth by 17%, while a 5% Argireline formula applied for 28 days did almost the same with a decrease in wrinkle depth by 16.26%. A Spanish University also did some research and found that Argireline increased the level of skin moisturization and decreased both the depth and width of wrinkles "significantly". This means, Acetyl Hexapeptide-8 does have some ability to smooth wrinkles (but not as well as Botox - sorry, if we sound like a broken record). Also, we have to agree with TruthInAging, that it's not a collagen builder and not a preventer of structural aging (think vitamin C, AHAs or retinol); it's just a quick fix. If you are looking for one, this could be your thing. If you are more of a "let's treat this aging thing properly" type, then it's probably not your thing. A four amino acid (Glycine – Glutamic acid – Lysine – Glycine) peptide that belongs to the group of signal peptides that mimic skin-protein breakdown products to trick the skin into creating some nice new skin proteins, such as collagen (if this sentence is not clear, here is a bit longer and nicer explanation). According to its manufacturer, Tetrapeptide-21 shows superior collagen, hyaluronic acid and fibronectin (all nice and important skin elements) boosting activity, and can smooth and minimize all kinds of wrinkles. The in-vitro data (made on human dermal fibroblast culture) showed that compared to Matrixyl (the first-generation Matrixyl peptide c what‑it‑does moisturizer/humectant cell-communicating ingredient | moisturizer/humectant solvent | moisturizer/humectant cell-communicating ingredient | skin brightening | anti-acne | moisturizer/humectant soothing | moisturizer/humectant irritancy, com. skin-identical ingredient | moisturizer/humectant antimicrobial/antibacterial moisturizer/humectant | emollient moisturizer/humectant | solvent
