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's there to help dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
- It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
- It is a humectant, which means that it helps attract moisture into the skin.
- It helps improve product application.
Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.


Ethylhexyl Salicylate is an organic compound used to block UV rays. It primarily absorbs UVB rays but offers a small amount of UVA protection as well.
Commonly found in sunscreens, Ethylhexyl Salicylate is created from salicylic acid and 2-ethylhexanol. You might know salicylic acid as the effective acne fighter ingredient and BHA.
The ethylhexanol in this ingredient is a fatty alcohol and helps hydrate your skin, similar to oils. It is an emollient, which means it traps moisture into the skin.
According to manufacturers, Ethylhexyl Salicylate absorbs UV wavelength of 295-315 nm, with a peak absorption at 307-310 nm. UVA rays are linked to long term skin damage, such as hyperpigmentation. UVB rays emit more energy and are capable of damaging our DNA. UVB rays cause sunburn.

Homosalate is a chemical sunscreen filter that provides protection in the UV-B range (280nm - 320 nm), with a peak protection at 306 nm. It is internationally approved for use in sunscreens.
Homosalate is not photo-stable, meaning it's strength as a UV filter degrades over time with exposure to the sun. Because of this, it's often used in combination with other chemical sunscreen filters as avobenzone (which protects from the UV-A range). Homosalate also helps act as a solvent for harder-to-dissolve UV filters.
(Part of the reason that sunscreens need to be frequently re-applied is due to the photo instability of many chemical sunscreen filters)
Currently, homosalate is approved in concentrations up to 10% in the EU and 15% in the US. The FDA is currently doing further research on the effects of homosalate, and it is possible that these approved concentrations will change in the future.
Dibutyl Adipate is an emollient and solvent. It is created from butyl alcohol and adipic acid.
As a solvent, Dibutyl Adipate helps mix and disperse ingredients evenly.
Dibutyl Adipate is soluble in water and organic solvents. It does not absorb UV rays.





Niacinamide has emerged as an all-star ingredient due to its many benefits.
It is known to treat acne by reducing inflammation fading dark-spots. It can strengthen the skin by promoting the growth of the ceramide barrier.
Other benefits include smoothing wrinkles and minimizing redness.
Niacinamide can also help build keratin, a protein that keeps skin firm.
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.
Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine is a UV filter that covers both UVA and UVB rays. It is synthetically created. Other names for this ingredient include Bemotrizinol and Tinosorb S (we'll use Bemotrizinol here).
Bemotrizinol has two peak UV absorption peaks ( 310 and 340 nm) and has shown to be effective at protecting against sun damage at small amounts. It is highly photostable and helps prevent the photodegration of other sunscreen ingredients such as avobenzone.
Bemotrizinol is not approved in the US but is allowed in the EU, Australia, and Asia.

Cyclopentasiloxane is a silicone used to improve texture and trap moisture. An easier name for this is D5.
D5 is considered lightweight and volatile. Volatile means it evaporates quickly after application. Once evaporated, D5 leaves a thin barrier that helps keep skin hydrated.
D5 is an emollient. Emollients help soften the skin and prevent water loss. Silicones create a silky texture in products. D5 helps other ingredients become more spreadable.
Studies show D5 is safe to use in skincare products. We recommend speaking with a skincare professional if you have concerns.
Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (Tinosorb M) is a hybrid and broad-spectrum UV ingredient. It is both a UV absorber and filter.
UV absorbers are an agent that absorbs UV rays. They protect your skin by using chemical reactions to convert UV rays into heat and energy. UV filters physically reduce the amount of UV rays from reaching your skin.
Tinosorb M covers a range of 280-400 nm and is photostable. This ingredient is neither oil or water soluble.
Tinosorb M, similarly to Tinosorb S, is not available in the US. However, it is available in the EU and Asia.
Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a chemical UVA absorber. It is formulated for high UVA protection (320-400 nm) and photostability.
DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%.
UV absorbers are an agent that absorbs UV rays. They protect your skin by using chemical reactions to convert UV rays into heat and energy.
UV rays are a form of electromagnetic radiation from the sun. Other sources include tanning beds and welding torches. Radiation is the emission of energy. UV Rays are divided into 3 groups. UVA (320-400 nm) contains the least amount of energy. They are linked to long term skin damage such as wrinkles and hyperpigmentation. UVB (290-320 nm) rays emit more energy than UVA rays. They are capable of damaging DNA in skin cells. UVB causes sunburns and are thought to be linked to skin cancer. UVC (200-280 nm) contains the highest amount of energy. Our ozone blocks UVC. UVC can also originate from welding torches, mercury lamps, and sanitizing bulbs.
1,2-Hexanediol is a multi-tasker ingredient. It acts as a preservative to increase shelf-life and can aid other preservatives in preventing microbe growth. 1,2-Hexanediol also helps the skin retain moisture as a humectant.
In products that are water-based, this ingredient can help stabilize perfumes and fragrances. It can also help make the texture of products softer and more smooth.
Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.
This property also makes Pentylene Glycol a great texture enhancer. It can help thicken or emulsify a product. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.
Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.
Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.
Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

Pinus Pinaster Bark Extract is an antioxidant.



Ceramide NP is one type of ceramide.
Ceramides are intercellular lipids naturally found in our skin that bonds dead skin cells together to create a barrier. They are known for their ability to hold water and thus are a great ingredient for dry skin.
Ceramides are an important building block for our skin barrier. A stronger barrier helps the skin look more firm and hydrated. By bolstering the skin ceramides act as a barrier against irritating ingredients. This can help with inflammation as well.
If you would like to eat ceramides, sweet potatoes contain a small amount.

Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also provides some UV protection by reducing the damage caused by UVB rays. Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Vitamin E aids in stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.
Astaxanthin is a carotene pigment and red pigment. It's what makes salmon a pink color.
Astaxanthin is an antioxidant and protects cells from free-radicals. Free-radicals are molecules that damage our cells.







Hyaluronic acid is naturally found in healthy skin. It is a humectant, meaning it draws moisture to your skin. Hyaluronic Acid has the capacity to bind to large amounts of water.
Hyaluronic acid helps hydrate, soothe, and protect the skin. It is already naturally found in our bodies, such as the fluids of our eyes and our joints.
Other characteristics of hyaluronic acid include anti-inflammatory and anti-microbial. Studies show hyaluronic acid helps speed up wound-healing due to these traits.
These are some other common types of Hyaluronic Acid:
Sodium Hyaluronate Crosspolymer is a type of hyaluronic acid. In fact, it is modified version of hyaluronic acid.
The structure of Sodium Hyaluronate Crosspolymer allows it to stay in the skin's top layer for a longer period of time. This allows for even more hydration and humectant action than hyaluronic acid.
