We don't have a description for Musa Paradisiaca Fruit Juice yet.
Dimethyl Sulfone is an organic compound that naturally contains sulfur. It is used as a solvent due to its stability. Solvents help mix and stabilize other ingredients.
Studies show taking Dimethyl Sulfone (also known as methylsulfonylmethane or MSM) orally may help reduce the depth of wrinkles. We recommend speaking with a professional if you have any questions or concerns about this ingredient.
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.
Learn more about Sodium HyaluronateSodium Lactate is the sodium salt of lactic acid, an AHA. It is a humectant and sometimes used to adjust the pH of a product.
This ingredient is part of our skin's NMF, or natural moisturizing factor. Our NMF is essential for the hydration of our top skin layers and plasticity of skin. NMF also influences our skin's natural acid mantle and pH, which protects our skin from harmful bacteria.
High percentages of Sodium Lactate can have an exfoliating effect.
Fun fact: Sodium Lactate is produced from fermented sugar.
Learn more about Sodium LactateThis ingredient is also known as sea fennel. It is a coastal plant extract with plant compounds like chlorogenic acid. This plant contains both "water" and "oil" parts.
One small human study (12 people over the age of 50) found formulas containing sea fennel biomass showed faster recovery of barrier function / TEWL after the barrier was deliberately disrupted.
A 2025 paper reported improved markers of regeneration in a UV-weakened full-thickness skin model using both water and oil parts. Markers include thicker epidermis, higher loricrin, and more collagen-related signals compared to an oil-only extract.
Broader phytochemical reviews describe antioxidant and anti-inflammatory activity in experimental models.
The plant's essential oil side can contain fragrant terpenes that can irritate sensitive skin, but many skincare formulas focus more on antioxidants like chlorogenic acid.
Learn more about Crithmum Maritimum ExtractChondrus Crispus Extract comes from a red algae native to the northern Atlantic coasts of Europe and North America. It helps hydrate the skin and is rich in antioxidants.
The antioxidants in chondrus crispus include lutein and zeaxanthin. Lutein has the ability to filter blue light from screens.
Other contents of chondrus crispus include polysaccharides, peptides, and amino acids. These help hydrate the skin.
What's the difference between algae and seaweed?
Algae is a broad term that includes seaweed. Not all algae is seaweed.
Melia Azadirachta Leaf Extract is extract from the neem plant.
The leaves of this tree contain flavonoids and polyphenols. These two compounds are antioxidants, anti-inflammatory, and antibacterial. Further research is needed as to their effects when applied on skin.
Melia Azadirachta Flower Extract is from the Neem tree. Neem trees originate from India.
Melia Azadirachta Flower Extract contains antioxidants. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.
The flowers of this tree are lilac colored.

Chelating agents help prevent metal ions from binding to other ingredients. This helps prevent unwanted reactions and effects from using the product. It also helps prevent the growth of unwanted microbes in products that contain water.
Caprylhydroxamic Acid is often used with natural antimicrobial products as an alternative to preservatives.
Learn more about Caprylhydroxamic AcidGlyceryl Caprylate comes from glycerin and caprylic acid. It is an emollient, co-emulsifier, and preservative booster.
Its short C8 fatty acid chain makes it behave differently from its longer-chain emollient cousins like Glyceryl Stearate. It feels more lightweight, fast-absorbing, and silky instead of rich and waxy.
As a co-emulsifier, its "head" and "tail" sit at the oil-water interface. But overall, the short C8 tail and not being water soluble means it doesn't really have the muscle to emulsify a formula on its own. That's why you'll often see it paired with a primary emulsifier like Cetearyl Glucoside.
Interestingly, Glyceryl Caprylate acts as a preservative booster. This is because its fatty-acid backbone disrupts microbial lipid membranes. It shows excellent activity against bacteria and yeast but is weaker against mold.
Typical concentrations range from 0.5-1% and this ingredient is generally non-irritating.
Because this ingredient has a C8 fatty acid chain, it is outside the range that the Malassezia yeast metabolizes (making it fungal acne safe).
Learn more about Glyceryl CaprylateGlycerin (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 GlycerinThis ingredient is derived from parts of the Italian honeysuckle plant. It has astringent, antioxidant, and antimicrobial properties.
Honeysuckle has a natural fragrance.
