Centella Asiatica Extract (Centella) is derived from an herb native to Southeast Asia. It is famous for its anti-inflammatory and soothing properties.
Centella is rich in antioxidants and amino acids, such as Madecassic Acid and Asiaticoside.
Studies show the compounds in centella help with:
The combination of all these properties makes centella effective at soothing, hydrating, and protecting the skin.
Other great components of centella include Vitamin A, vitamin C, several B vitamins, and Asiatic Acid.

Learn more about Centella Asiatica ExtractCentella Asiatica Leaf Extract comes from the leaves of an herb plant native to Southeast Asia. Centella Asiatica is rich in antioxidants and amino acids. It can help reduce irritation and soothe the skin.
Many active components found in centella asiatica, such as Madecassic Acid and Asiaticoside, encourage the skin to naturally produce hyaluronic acid. This helps keep our skin hydrated. Many of these components also show antioxidant activity and may help reduce the signs of aging.
Research shows centella asiatica can help increase Type I collagen production by increasing fibroblast production. Fibroblast helps form connective tissue.
The combination of all these properties makes centella asiatica leaf extract effective at soothing the skin.
Other components of centella asiatica leaf extract include Vitamin A, vitamin C, several B vitamins, and Asiatic Acid.
Recent studies found madecassoside may help prevent damage from UV rays by preventing UV-induced inflammation. Further research is needed.
This plant has been used as a medicine and in food for many centuries. As a medicine, it is used to treat burns, scratches, and wounds.

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.
Learn more about Butylene Glycol1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.ย
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 preservativesย
Panthenol 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.

Allantoin is a soothing ingredient known for its protective and moisturizing properties; it's basically a quiet workhorse ingredient you can find in a huge range of cosmetics.
Though it can be derived from the comfrey plant, allantoin is produced synthetically for cosmetic products to ensure purity.
Research shows it can encourage your skin cells to turn over and renew by stimulating keratinocyte and fibroblast proliferation.
It also has mild keratolytic properties to help loosen and shed dead skin cells without being harsh.
Studies also suggest allantoin can help calm inflammation by dialing down some of the chemical signals your skin sends out when it is irritated.
This ingredient is typically used in the 0.1-0.5% range, and the FDA recognizes it as a skin protectant in OTC products up to 2%.
Overall, allantoin is a wonderful addition to most routines; it is stable across a wide pH range (~4-8), works well with other ingredients, and is considered non-sensitizing/non-irritating.
Fun fact: Allantoin is naturally occurring in comfrey root, beets, chamomile, and wheat sprouts. Our bodies even produce it as a byproduct of uric acid metabolism.
Learn more about AllantoinGlycerin (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.
Learn more about GlycerinPolyglyceryl-10 Laurate is a cleansing agent and emulsifier.
It rounds up dirt, oil, and grime, so they can be rinsed off easily as a cleanser. On the emulsifier side, it keeps your formula smooth and well-mixed by playing peacekeeper for ingredients that don't naturally get along (like oil and water).
Because it has a C12 (lauric acid) fatty acid chain, this ingredient can potentially feed the Malassezia yeast that causes fungal acne. The Malassezia yeast prefers esters with C11-C24 fatty acids If you're prone to flare-ups, you might want to patch-test or skip this one.
This ingredient is an ester of lauric acid and Polyglycerin-10.
Learn more about Polyglyceryl-10 LauratePolyglyceryl-10 Myristate is a nonionic emulsifier and skin conditioner made from Polyglycerin-10 and Myristic Acid.
As a skin conditioning agent, this ingredient leaves skin feeling soft without a greasy finish. As an emulsifier, it helps stabilize oil-in-water emulsions.
You'll likely see this ingredient in "clean" formulations because it's considered a natural alternative to PEGs.
Patch testing at concentration 0.1-1% showed no reactions and this ingredient is considered to be well-tolerated across skin types.
Due to its myristic acid base, this ingredient may not be fungal acne safe.
Learn more about Polyglyceryl-10 MyristateThis is a synthetic polymer. It helps improve the texture of products by adding thickness and gel-like feel.
It is also an emulsifer, meaning it prevents ingredients such as oil and water from separating. It also helps evenly disperse other ingredients.
Alpha-Arbutin is made from hydroquinone and glucose. It may also be derived from the fermentation of soybeans.
This ingredient an antioxidant, meaning it helps protect your skin cells against damage.
Studies show this ingredient helps improve hyperpigmentation and fade discoloration.
Alpha-Arbutin may be used with other ingredients that help with hyperpigmentation. These ingredients include retinol, Vitamin C, niacinamide, and tranexamic acid.

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 GumAsiaticoside comes from the super popular skin-soothing ingredient, Centella asiatica. It's the reason centella-based products have a strong reputation for repairing and calming skin, along with its sibling compound Madecassoside.
Research from 2016-2025 supports its role in:
You'll usually find this in concentrations between 0.2-5%.
Learn more about AsiaticosideAsiatic Acid is a major component of Centella Asiatica Extract. It has wound-healing, anti-inflammatory, and antioxidant properties.
Studies show Asiatic Acid is able to block the pathway for skin inflammation receptors, helping to soothe skin.
As an antioxidant, asiatic acid helps protect our skin against damaging environmental factors.
Learn more about Asiatic AcidMadecassic Acid is a major component of Centella Asiatica Extract. It has anti-inflammatory and antioxidant properties.
It is a triterpenoid, meaning it naturally acts as an antioxidant. Antioxidants protect your skin against damage from environmental factors such as pollution and UV.
Studies show Madecassic Acid helps soothe the skin due to its ability to block inflammation pathways.
Learn more about Madecassic AcidMadecassoside is one of four active compounds found in Centella asiatica and is one of the main reasons Centella is so effective at calming irritated skin and supporting the moisture barrier.
There's a solid body of peer-reviewed research backing Madecassoside for several skin benefits. Studies have found:
Madecassoside pairs well with other hydrating or antioxidant ingredients like Ascorbic Acid or Hyaluronic Acid.
Learn more about MadecassosideSodium 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.
