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!

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.

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.

It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

The term 'algae extract' can refer to any one, or a blend of, the 30,000 types.
Algae is rich in antioxidants. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.
Algae can also help with soothing and hydrating skin.
Many different types of algae have different benefits.

Antioxidants help protect the skin against free-radical molecules. These molecules may originate from UV rays or pollution. Spirulina Platensis is rich in beta-carotene, a potent antioxidant.
Spirulina Platensis also contains Vitamin A, Vitamin E, and proteins.

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.

Brown kelp are rich in unsaturated fatty acids and phlorotannins. Phlorotannins have been found to help with inhibiting melanin production and helping reduce the signs of aging due to their high antioxidant activity.
One study suggests phlorotannins may even have some sun protection factor due to their antioxidant activity. However, this ingredient should not replace your sunscreen.
Macrocystis pyrifera is made up of about: 60% carbohydrates, 10% protein, and 1.50% lipid content. The last 30% is kelp ash.
This kelp can be found in the southern hemisphere and north Pacific.

You’ll most often find this ingredient listed under the trade names Antarcticine or Arctalis.
According to a manufacturer, these ingredients encourage skin regeneration and smoothness by stimulating collagen and elastin production. A manufacturer study found creams containing 1–5% Antarcticine increased skin hydration and reduced wrinkle depth around the eyes.
The manufacturer also claims this extract can help regulate oily skin by reducing sebum production, shine, and minimizing pore size.
Some people have reported that ferments may trigger Malassezia folliculitis. For this reason, we list it as not fungal-acne safe, though individual reactions can vary.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
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%.
