A menthol-derived cooling agent that is claimed to give a long-lasting cooling effect (similar to menthol itself) while also being moisturizing and less irritating than menthol thanks to the lactic acid part. It's recommended to be used at 0.5-1%.  

A spherical powder that holds more than 20 times its dry weight in water. Sodium Acrylates Crosspolymer-2 gives formulas a unique gel-to-water-to-powder transformation. It also has a blurring effect on lines & wrinkles. 

Hydrogenated Vegetable Glycerides is a blend of fatty acid mono and diesters (kind of like an oil molecule but not with three but only one or two fatty acid chains on the glycerin) that exists in lots of versions. It can be a consistency-giving wax (think something like glyceryl stearate), or it can be a rich jelly emollient that acts as a petrolatum alternative. 

There is not much information about Phytosteryl Sunflowerseedate on its own out there, but it usually comes to the formula combined with Dilinoleic Acid/​Propanediol Copolymer and Hydrogenated Vegetable Glycerides. The trio acts as a vegetable lanolin alternative, bringing rich emollience to the formula. 

Dilinoleic Acid/Propanediol Copolymer is a slightly tacky, glossy emollient that is commonly used in lip products as it is soluble in lip product's favorite oil, castor oil; it sticks well to the skin (substantive) and gives a nice glossy appearance. It also often comes to the ingredient list (especially in non-lip products) combined with Phytosteryl Sunflowerseedate and Hydrogenated Vegetable Glycerides; in this case, the trio serves as a vegetable lanolin alternative, bringing rich emollience to the formula. 

Cetyl Lactate is a multipurpose emollient that gives the formula a nice slip and makes your skin silky and smooth. It is also claimed to reduce tackiness and greasiness in the formulation. 

A castor oil-derived polymer that can thicken up oils. It can form clear oily gels, and it can also suspend particles such as pigments, glitters, or mineral filters. 

A high stability high oleic acid oil derived from microalgae in an eco-friendly process. It works as an emollient in the formula, similar to other vegetable oils. 

An environmentally friendly, biodegradable film former and SPF booster used in sunscreen products. It helps sunscreens create a nice, even layer on the skin that stays there for a long time. 

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 called Palmitoyl Pentapeptide-4), the collagen production in the presence of Tetrapeptide-21 was almost 2-fold higher (and about 2.5-fold vs the control). This data was confirmed by an in-vivo study that compared on 60 volunteers 0.5% Tego Pep 4-17 (10ppm of Tetrapeptide-21), 5% Tego Pep 4-17 (100ppm of Tetrapeptide-21) and 10% Matrixyl (10ppm of Palmitoyl Pentapeptide-4) and found that Tetrapeptide-21 performed better after 8 weeks for skin volume, roughness and elasticity. The manufacturer also did another 60 people anti-wrinkle study with 4% Tego Pep 4-17 (compared to vehicle) where they have some nice before and after pictures showing visible-to-the-naked-eye wrinkle reduction around the eye area. 

A type of bucket or donut-shaped molecule with a water-loving outer side and an oil-loving inner side that is used mostly to encapsulate other actives in cosmetics. 

Copper Palmitoyl Heptapeptide-14 is the payload peptide (a short chain of amino acids) in the encapsulated copper peptide technology trade named X50 Antiaging. The delivery system (called The Cosmetic Drone) is a high-tech capsule where our peptide is wrapped in a biocompatible polymer shell (created from Lactic Acid/Glycolic Acid Copolymer, Polyvinyl Alcohol) and another peptide, which has an affinity to the fibroblast receptors, sits on the outside of the capsule and guides it to the right place in the skin. The right place in this case is the fibroblast cell (the important collagen-producing cell in the dermis), so once Copper Palmitoyl Heptapeptide-14 is there, it promotes the gene expression of both collagen and elastin. According to the 30-person in-vivo (made on real humans) test of the manufacturer, the participants experienced an average of 33% reduction in wrinkles and 19% increase in elasticity in 28 days. Thanks to the advanced delivery system, the active works at the tiniest concentration of 0.001%. Fun fact: the unit of sale for the X50 Antiaging powder is not kg as all other actives but it is g, this is how little you need from it. 

Heptapeptide-15 Palmitate is the targeting peptide (a short chain of amino acids) that is part of the encapsulated copper peptide technology trade named X50 Antiaging. This smart guy sits at the outer part of the encapsulation shell and seeks out the all-important collagen-producing cells in the middle layer of the skin called fibroblasts. Once Heptapeptide-15 Palmitate binds to the receptors of the fibroblast, the cell internalizes the capsule, and the payload (in this case Copper Palmitoyl Heptapeptide-14) is released.  Continue here to read what the payload peptide is doing once it arrives at its target, the fibroblast cell. 

As a plant extract, it is hard to know what it is exactly: it might be little exfoliant particles, or - if you are looking at the ingredient list of an anti-aging product - it is most likely a rye extract rich in arabinoxylans with possible skin smoothing and glow enhancing properties. According to manufacturer claims, their rye extract can improve the skin’s mechanical resistance and reduce the appearance of gravity wrinkles. The manufacturer did a 20-person, 56-day long study that showed an antiwrinkle effect at both the crow’s-feet and the nasolabial fold: a 13% and 23% decrease in the number of wrinkles, a 15% and 26% reduction of the total surface of wrinkles, and a 16% and 27% reduction of their length.
