Benefits
Ingredients Explained
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!
Learn more about WaterButylene 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.

Acrylates Copolymer is used as a film-forming agent and texture enhancer.
After applied, Acrylates Copolymer forms a thin film cover that helps skin feel more soft. It can help sunscreens become more water-resistant.
It is also used to make a product more thick.

Research on alkanediols (the family pentylene glycol belongs to) show they work by disrupting microbial cell membranes. This disruption helps the primary preservative system in a product work more effectively at lower doses.
On the safety side, the Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe as used in current cosmetic practices + concentrations.
Typical use levels in a formula run about 1-5%.

Ginseng root is a well-loved ingredient in Asian skincare for good reason. It hydrates the skin, soothes irritation, and helps even out skin tone.
In traditional East Asian medicine, ginseng has been used for centuries both as food and as a healing remedy, and modern research continues to confirm its skin benefits.
One of the standout features of ginseng is its ability to improve blood circulation and oxygen delivery to the skin, bringing a fresh supply of nutrients to support overall skin health. It also has antioxidant and anti-inflammatory properties. This helps to protect your skin against damage from UV exposure, pollution, and daily stress.
Additionally, studies suggest that ginseng may help reduce hyperpigmentation by inhibiting tyrosinase, the enzyme involved in melanin production.
There are different types of ginseng used in skincare, and while they all share core benefits, their potency can vary.
Most products use fresh or white ginseng because it’s more affordable. However, red ginseng, produced by steaming the root, contains higher levels of ginsenosides, which are compounds with proven anti-aging effects. These ginsenosides help reduce the appearance of wrinkles and improve skin elasticity.
Note: All forms of ginseng are listed simply as “Panax ginseng” in ingredient lists. We recommend reaching out to the brand if you have questions about which type of ginseng is used in their ingredients.
For general antioxidant benefits, any ginseng extract will do, but for wrinkle care or firmer skin, red or fermented ginseng is often more effective.
In short, ginseng is a powerhouse ingredient that supports hydration, radiance, and resilience.
Learn more about Panax Ginseng Root ExtractThis ingredient comes from the leaves of the evergreen tea, Eriobotrya japonica (loquat). It has skin conditioning and protecting properties.
The leaves of this tree are rich in antioxidants that help soothe and protect the skin from oxidative stress.
Some studies suggest this ingredient may inhibit pigment production in the skin to help even out skin tone.
Learn more about Eriobotrya Japonica Leaf ExtractPanthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.
There are two forms of panthenol: D and L.
D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.
Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):
Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.
This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.
This ingredient is also referred to as pro-vitamin B5.

Adenosine Phosphate is an antioxidant and helps soothe skin.
Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.
On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.
Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.
Learn more about Xanthan GumSimethicone is a silicone. It is an emollient and used to reduce foaming in a product. It is also often used to coat sunscreen ingredients for better spreadability.
This ingredient is created by mixing dimethylpolysiloxane and hydrated silica.

Dehydroacetic Acid is a synthetic preservative that keeps your products safe from microbes.
As an organic acid, it penetrates microbial cell walls and disrupts cellular metabolism. This makes it effective against bacteria, yeast, and mold.
It is effective at low concentrations (<0.6%). Clinical studies have found it to be non-irritating, non-sensitizing, and non-photosensitizing.
Learn more about Dehydroacetic AcidPhenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!).
It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome.
On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive.
Another perk of this ingredient is that it stays functional across a wide pH range (3-10).
You'll often see it paired with boosters like Ethylhexylglycerin; one study showed that a 1:9 ratio of Ethylhexylglycerin to Phenoxyethanol damages bacterial membranes as effectively as doubling the Phenoxyethanol concentration on its own.
Typical use concentrations range from 0.3-1% depending on the formula, and this ingredient is capped at 1% int the EU.
Safety-wise, the fear mongering does not hold up to the evidence. The EU's Scientific Committee on Consumer Safety and FDA consider it safe as a preservative at up to 1%, including for children of all ages.
Adverse systemic effects only showed up in animal studies at exposures roughly 200x higher than what people get from cosmetics. And despite its very widespread use, this ingredient is a rare sensitizer and allergic reactions are uncommon.
Learn more about PhenoxyethanolCI 17200 is a synthetic, water-soluble, reddish-pink dye. It is used purely as a cosmetic colorant.
In the US, the FDA permits this ingredient in cosmetics but it is not approved for use around the eyes while the EU allows this to be used in all cosmetic products.
The FDA requires batch-to-batch certification for this ingredient that is held to a pretty rigorous standard. That means the CI 17200 in your cosmetics has been tested and approved before it ever reaches you.
Contact allergy to cosmetic-grade dyes used at low concentrations are uncommon but has been documented before.
This ingredient also goes by the name D&C RED NO. 33.
CI 17200 has a comedogenic rating of 1 and an irritancy rating of 2 on a scale of 0-5. This is based on peer-reviewed research from the man who invented the comedogenic scale.
A 1 on the comedogenic scale is about as low as it gets without being a flat zero, and makes sense for CI 17200.
It's a water-soluble dye used at very small concentrations (typically 0.001-0.1%), so it dissolves into the water phase of a formula rather than sitting on your skin the way an oil or wax would.
The irritancy rating of 2 reflects that, like most synthetic dyes, there's a small possibility of mild irritation ( particularly for people with existing dye sensitivities).
For the vast majority of people, it's a non-issue at typical use levels.
It's also worth keeping in mind that comedogenic and irritancy ratings are tested on individual ingredients, not finished formulas. The final product's formulation, concentration, and other ingredients all play a role in how something actually behaves on your skin.
Just so you know, the FDA ban on Red Dye No. 3 refers to CI 45430, not this ingredient. CI 45430 and CI 17200 are different chemical compounds with distinct safety and regulatory histories.
It's also worth noting that Red No. 3 (CI 45430) was already banned from cosmetics back in 1990, so the 2025 action just extended the ban to food and oral drugs. CI 17200 was never part of any of this.
Learn more about CI 17200CI 19140 is also known as Tartrazine. Tartrazine is a synthetic dye used in cosmetics, foods, and medicine to add a yellow color.
Tartrazine is created from petroleum and is water-soluble.
Some people may experience allergies from this dye, especially asthmatics and those with an aspirin intolerance.
Learn more about CI 19140Ci 42090 is a synthetic dye created from petroleum. It is used to give a bright blue color to cosmetics, medicine, and food.
