Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.
It is a:
Humectant, drawing moisture into the skin
Emollient, helping to soften skin
Solvent, dispersing and stabilizing formulas
Preservative booster, enhancing the antimicrobial activity of other preservatives
Adenosine is a purine nucleoside that your body already makes in every cell. In skincare, it acts mainly as a skin conditioning and anti-aging agent.
The way it works is fairly well mapped out:
Your skin has cells called fibroblasts that build collagen (the stuff that keeps skin firm and smooth). Adenosine basically flips a switch on these cells that tells them to get to work making more collagen and other proteins. These cells slow down on their own as skin ages, so Adenosine helps give them a little nudge to keep going.
The clinical backing is pretty solid too.
A blind, randomized, placebo-controlled trial of 126 women aged 45-65 tested a 0.1% cream twice daily and found real improvements in crow's feet and frown lines using a precise 3D skin-mapping technique; these changes showed up by week 3 and held at 2 months.
A later study using Adenosine-loaded dissolving microneedle patches reported gains in wrinkle depth, dermal density, elasticity, and hydration.
On concentrations, South Korea's Ministry of Food and Drug Safety has set 0.04% as the approved functional anti-wrinkle level. You'll typically see this ingredient used somewhere in the 0.04-0.1% range since it works at low doses.
This ingredient has been found safe for cosmetics with the data showing no irritation or sensitization.
Overall, this is a great ingredient for any anti-aging routine and has no photosensitizing effect, so it suits both AM and PM use.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
Cyanocobalamin is the manufactured version of vitamin B12. It has skin soothing, antioxidant, and barrier protecting properties. Topical cyanocobalamin is used to treat skin irritation and atopic dermatitis.
Disodium EDTA is a chelating agent. It grabs onto and deactivates metal ions that sneak into your products from water, packaging, or air.
This ingredient mainly works behind the scenes and helps with:
On top of that, this ingredient can counteract the effects of hard water by binding to the minerals in it.
One thing worth knowing is that Disodium EDTA has been shown to be a mild penetration enhancer. It can help other ingredients absorb into skin more effectively which can be a double-edged sword (great for actives, but can also make the active too strong if you have sensitive skin).
Clinical patch testing showed no significant skin irritation at typical use concentrations and minimal dermal absorption.
You'll most likely see this ingredient near the end of an ingredient list. It's typically found in concentrations less than 1%.
Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that:
The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure.
Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.
Glycereth-26 is a synthetic ingredient and polyethylene glycol ether of Glycerin. Glycerin is already naturally found in your skin and helps keep your skin moisturized.
It is a humectant and helps add texture to products. It can make your product thicker.
As a humectant, it helps draw moisture from the air to your skin. This helps your skin stay hydrated.
Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
Topically, glycerin does several things at once:
Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
Just know very high concentrations (>40%) can feel tacky in low humidity.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
Glyceryl Acrylate/Acrylic Acid Copolymer is made up of glycerin and polyacrylic acid. It helps hydrate your skin as a humectant.
This ingredient forms a hydrogel that delivers moisturizing, water-based ingredients to the skin. It is also used to thicken a product and to give it a smooth texture.
Acrylic acid itself is toxic, but the polymer form (this ingredient) is too large to penetrate skin, making it non-toxic.
Niacinamide is a multitasking form of vitamin B3 that strengthens the skin barrier, reduces pores and dark spots, regulates oil, and improves signs of aging.
And the best part? It's gentle and well-tolerated by most skin types, including sensitive and reactive skin.
You might have heard of "niacin flush", or the reddening of skin that causes itchiness. Niacinamide has not been found to cause this.
In very rare cases, some individuals may not be able to tolerate niacinamide at all or experience an allergic reaction to it.
If you are experiencing flaking, irritation, and dryness with this ingredient, be sure to double check all your products as this ingredient can be found in all categories of skincare.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
When you apply niacinamide to your skin, your body converts it into nicotinamide adenine dinucleotide (NAD). NAD is an essential coenzyme that is already found in your cells as "fuel" and powers countless biological processes.
In your skin, NAD helps repair cell damage, produce new healthy cells, support collagen production, strengthen the skin barrier, and fight environmental stressors (like UV and pollution).
Our natural NAD levels start to decline with age, leading to slower skin repair, visible aging, and a weaker skin barrier. By providing your skin niacinamide, you're recharging your skin's NAD levels. This leads to stronger, healthier, and younger looking skin.
Another name for vitamin B3 is nicotinamide. This vitamin is water-soluble and our bodies don't store it. We obtain Vitamin B3 from either food or skincare. Meat, fish, wheat, yeast, and leafy greens contain vitamin B3.
The type of niacinamide used in skincare is synthetically created.
Salmon egg extract is a marine-derived ingredient that comes from, well, salmon eggs.
At this time, the official CosIng database has not reported any functions or properties for this ingredient.
We do know that this ingredient is packed with proteins, unsaturated fatty acids, phospholipids, vitamins, minerals, and the powerful antioxidant, Astaxanthin.
In vitro studies show that this ingredient boosts collagen type I production and activates several important antioxidant genes. And the more extract used, the stronger the effect too.
A randomized clinical trial with 66 volunteers tested it at 1% and 5% concentrations for almost two months and found significant improvements in skin aging and overall skin health.
This ingredient is sometimes listed as Salmo Ovum Extract.
Sodium DNA is an emerging anti-aging ingredient.
It is created by taking deoxyribonucleic acid (DNA) and purifying it with sodium hydroxide.
The DNA is extracted from several different animal sources, including: calf thymus, the gonadic tissue of a male sturgeon, or herring / salmon sperm.
You have probably seen this ingredient in anti-aging skincare. But what is it?
DNA is composed of nucleotides, or chemical building blocks. Nucleotides include adenine (A), thymine (T), guanine (G), and cytosine (C). Talk about a flashback to biology! Nucleosides are formed from these nucleotides.
The science behind Sodium DNA is based on an ingredient called Polydeoxyribonucleotide or PDRN.
PDRN are DNA fragments mainly extracted from the sperm cells of trout or salmon. Meaning, PDRN can be derived from Sodium DNA.
PDRN consists of chains of nucleotides and nucleosides mentioned above. They can range anywhere from 80 - 2000 pairs.
Studies show PDRN has the following properties:
Most of the research on PDRN has been done using injectable forms. That’s important, because PDRN is a large molecule and doesn’t absorb well through the skin. So if you’re applying it topically, the effects are likely to be much milder.
Still, topical Sodium DNA is emerging as a trendy anti-aging ingredient. It’s generally well-tolerated and offers good biocompatibility with human skin, making it a low-risk addition to most routines.
Further studies are needed to truly confirm this ingredients anti-aging ability (Remember, retinol has decades of research!).
Sodium DNA may be sourced from fish, animal tissue, or plants. Since this isn’t always disclosed, we recommend asking the brand directly if the ingredient’s origin is important to you.
Sodium Hyaluronate is the salt form of hyaluronic acid. It is a long sugar chain that is naturally found in your skin, joints, and connective tissue that maintains hydration and elasticity.
In skincare, it works as a humectant. It pulls water from the environment and deeper layers of skin and binds it to the surface.
Interestingly, the size of the molecule affects its behavior:
Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair.
Many serums use a blend of both weights so you can get surface hydration plus longer-lasting and deeper effects.
You'll typically see concentrations between 0.1-2% for this ingredient.
Tromethamine (aka THAM) is a synthetic amino acid that shows up in skincare as a helper ingredient.
It functions as a pH adjuster to help neutralize acidic ingredients and set a formula's pH to the right spot.
This matters a lot because a lot of actives (like vitamin C) needs a specific pH to work well and feel comfortable on skin.
Concentration use ranges from 0.1-1.0% depending on the formula.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
