Ingredients Explained

Skin Conditioning, Solvent

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!

Emollient, Humectant, Skin Conditioning

Aloe Barbadensis Leaf Extract is a botanical extract pulled from the leaves of aloe vera and one of the most studied plant ingredients in cosmetics.

The inner leaf gel it comes from is mostly water (~99-99.5%) and the remaining fraction is made up of pretty good stuff: polysaccharides, vitamins, phenolics, and enzymes.

Its headline job is hydration.

The star polysaccharide in aloe, acemannan, is a humectant that retains moisture and helps reduce trans-epidermal water loss.

Aloe also has real soothing credentials; it contains anti-inflammatory compounds like bradykinase and C-glucosyl chromone that help calm irritation and redness.

On the repair side, lab work shows that acemannan wakes up your skin's repair cells (fibroblasts), prompting them to multiply and speed up healing.

There's some human data for cosmetic benefit too: a cream containing 10% Aloe Barbadensis leaf extract improved skin hydration and elasticity in a real-use study.

Safety-wise, this ingredient is well-regarded with just one rare downside; there have been some case reports of acute eczema, contact urticaria, and dermatitis in people who applied aloe-derived ingredients topically. Those with a known aloe or Liliaceae sensitivity should patch test.

Typical use levels range widely, from under 1% up to 90%+ depending on the format and the effect you are after.

Masking, Perfuming, Tonic

Vetiver oil is known for its earthy fragrance. It is most often used for adding a scent or fragrance to a product.

Recent studies have found potential antioxidant activity of vetiver root oil.

Masking, Skin Conditioning, Skin Protecting

Rosa Damascena Flower Water is the water-based byproduct of steam-distilling damask rose petals. It has skin conditioning, masking, and skin protecting properties.

Research shows that Rosa damascena is rich in flavonoids and phenolic compounds like gallic acid that contribute to its antioxidant activity.

In vitro studies have shown that Rosa damascena can scavenge free radicals and reduce melanin overproduction. Research has also found this extract offers some degree of UV absorption but this should not replace your sunscreen.

Skin Conditioning

Phospholipids are a family of skin-identical lipids that makeup the structural backbone of every cell membrane in your body.

In cosmetics, they function as skin conditioning agents with emulsifier and surfactant properties. They're typically sourced from soybean or sunflower lecithin (or sometimes egg yolk or marine sources).

Because they mirror the lipids naturally found in the deeper layers of your skin, topical phospholipids help reinforce the lipid matrix, reduce transepidermal water loss, and leave skin feeling conditioned.

They're also used to form liposomes, or tiny self-assembling vesible used to stabilize actives like vitamin c or retinol. This helps these ingredients integrate into the upper layers of skin more easily.

Phospholipids are compatible with everything and the CIR Expert Panel has concluded them to be safe at current use levels.

Some types of phospholipids include:

Humectant

Glucose is a simple sugar (a monosaccharide). In skincare, it is mostly a humectant and skin conditioning agent.

Mechanistically, it has multiple hydroxyl groups that hydrogen-bond to water. This pulls moisture into the upper layers of skin to keep the surface soft and hydrated.

It's worth knowing sugars are already a natural component of the skin's NMF (natural moisturizing factor) so it's a molecule that your stratum corneum is well-acquainted with.

Just so you know, glucose is hydrophilic (water-loving) and the stratum corneum is a strong barrier to hydrophilic compounds. This just means penetration is slow and most of the action is happening on the surface.

Gram-to-gram, glucose is not as efficient as a humectant as glycerin. This is why you'll likely see glycose paired with stronger humectants for a bigger hydration payoff.

In skincare, glucose is typically derived from corn or other starch sources.

Withania Somnifera Root Extract is also known as Ashwaganda extract. Ashwaganda is an evergreen shrub grown in India, the Middle East, and parts of Africa.

Ashwaganda contains many antioxidant compounds. Antioxidants may help with anti-aging as they neutralize free-radical molecules. These molecules may damage skin cells and DNA. By neutralizing them, antioxidants may help slow the signs of aging.

Other compounds found in ashwaganda include Vitamin C, caffeic acid, and ferulic acid. These three acids are antioxidants but also provide other skin benefits as well.

Ongoing studies show ashwaganda to prevent damage from UV-B radiation.

Ashwaganda root powder has traditionally been used in Indian medicine.

Skin Conditioning

Ginkgo Biloba Leaf Extract comes from the leaves of the Ginkgo tree. It has soothing and antioxidant properties.

The leaves of ginkgo contains flavonoids and terpenoids, potent antioxidants. Antioxidants may protect your skin from damage caused by external sources such as pollution.

Its soothing ability comes from a variety of compounds including biflavones, a type of flavonoid. Studies show gingko biloba has strong anti-inflammatory properties.

Fun fact: This tree is native to China and has been used in traditional Chinese medicine for thousands of years.

Skin Conditioning

Polyglutamic Acid is made up many glutamic acids chained together. It is created from bacterial fermentation.

This ingredient is an effective skin hydrator and may help speed up wound healing. As a humectant, it draws and holds water to the skin. This ingredient is often compared to hyaluronic acid or glycerin. Similarly to hyaluronic acid, it can vary in molecular weights. This means polyglutamic acid is capable of bringing hydration to lower levels of the skin.

Fun fact: Polyglutamic Acid is found in the Japanese food, natto. It is also being used in cancer treatment studies.

Aesculus Hippocastanum Extract is derived from horse chestnut native to Southeastern Europe.

It is an antioxidant and helps soothe skin. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.

Sambucus Nigra is known as the black elderberry.

Black Elderberry contains flavonoids, which are antioxidants. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells.

This ingredient comes from the skin of grapes. It has antioxidant properties.

Skin Conditioning

Sodium levulinate is the a sodium salt of Levulinic Acid. Oncedissolved in an aqueous solution, the two ingredients become identical. It is usually derived from renewable plant sources like corn starch or sugarcane.

In skincare, it mostly acts as a skin conditioning agent that keeps skin soft and hydrated. It also acts as a preservative booster by inhibiting the growth of mold, yeast, and bacteria.

It's often paired with Sodium Anisate as the two create a broad-spectrum preservative system that is popular in "natural" formulations.

This ingredient is water-soluble.

The CIR Expert Panel for Cosmetic Ingredient Safety has concluded this ingredient to be non-irritated and there are no restrictions for use in EU cosmetics. The FDA also allows this ingredient to be used as a food-grade flavoring agent.

Antimicrobial

Sodium Anisate comes from fennel. It is used as a preservative and to add flavoring.

Sodium Anisate has antimicrobial properties.

Antioxidant, Masking, Skin Conditioning

Tocopherol is a fat-soluble antioxidant known as Vitamin E.

You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.

Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.

It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.

This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.

This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.

In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.

Concentrations usually range from 0.1-1% in most leave-on products.

Antioxidant

Glucosylrutin is a plant-derived antioxidant that helps neutralize reactive molecules created by UV exposure and environmental stress.

Clinical studies show its strongest benefits when used alongside broad-spectrum UVA protection. In these studies. blucosylrutin helped reduce sun-induced skin reactions such as polymorphus light eruption (sun induced rashes) and itching.

Compared to rutin, glucosylrutin is more stable and easier to formulate into water-based products (it's water soluble).
