Aloe Barbadensis Leaf Extract is an extract of the leaves of the aloe, Aloe barbadensis, Liliaceae.

Aloe is one of the most well-known natural soothing ingredients, and for good reason. It’s full of water and has a cooling, calming effect on the skin, especially when it’s sunburned, itchy, or irritated. Aloe also helps your skin stay hydrated and smooth by mimicking what healthy skin naturally produces. On top of that, it contains vitamins and nutrients that support skin recovery. 

It doesn’t protect you from the sun, but it can help your skin bounce back after too much time in it.

Let’s get into the details:

Aloe contains antioxidant Vitamins A, C, and E, which help fight off free radicals (unstable molecules from things like pollution that can damage your skin).

It’s also rich in polysaccharides, which are natural sugars that help hydrate the skin by acting like the skin’s own moisturizing agents. These, along with other sugars like monosaccharides, help form a protective barrier that locks in moisture.

Aloe works as both a humectant and an emollient. That means it draws water into the skin (humectant) and helps trap it there (emollient), making it an effective natural moisturizer.

You’ll also find a mix of other skin-supporting ingredients in aloe, including folic acid, choline, calcium, amino acids, fatty acids, and even Vitamin B12.

Out of the 420+ species of aloe, Aloe barbadensis is the most widely used in skincare products thanks to its gentle yet effective properties.

There are over 420 species of aloe but Aloe Barbadensis is the most commonly used for topical products.

Camellia Sinensis Leaf Extract is derived from the leaves of the tea plant. Black tea, green tea, and oolong tea are all harvested from this plant.

This ingredient has many skin benefits:

This ingredient contains polyphenols, a strong antioxidant. Antioxidants help fight off molecules that damage skin cells.

On top of that, the antioxidants in green tea neutralize free-radicals from the sun. This gives the skin some extra UV protection, but should not replace sunscreen.

Many components of tea have anti-inflammatory properties.

Polyphenols and L-theanine help soothe the skin and reduce irritation. The caffeine in Camellia Sinensis Leaf Extract helps calm inflamed blood vessels.

Other compounds found in tea include: Vitamin Bs, linoleic acid, magnesium, calcium, iron, and zinc.

Research has shown both drinking Camellia Sinensis Leaf Tea and applying it to the skin can help boost skin elasticity and hydration. Studies also show using tea extract may reduce sebum, or oil, production.

Galactomyces Ferment Filtrate (GFF) is a yeast traditionally used to make the Japanese alcoholic beverage, sake.

GFF has moisturizing and antioxidant properties.

Studies show GFF improves our skin's natural moisturizing factors (NMF). Our NMF consists of many components that naturally moisturize our skin. Having healthy NMF keeps our skin plump, protected, and hydrated.

This ingredient tells our skin to create more filaggrin, an important component for NMF.

Filaggrin gathers all the structural proteins in our outer layer of skin and creates a tight barrier, helping to protect our skin against allergens and bacteria. This also helps prevent moisture loss.

Thanks to its antioxidant properties, GFF also protects our skin against oxidative stress and UV induced inflammation.

One study found GFF helped regulate sebum (oil) production and keratin in participants.

GFF may not be fungal-acne safe. We recommend speaking with a professional if you have concerns.

Many components of sake, such as GFF, are studied for their anti-aging benefits today. This is because sake brewers are known to have youthful hands.

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

This ingredient is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Ginseng root is a well-loved ingredient in Asian skincare for good reason. It hydrates the skin, soothes irritation, and helps even out skin tone.

In traditional East Asian medicine, ginseng has been used for centuries both as food and as a healing remedy, and modern research continues to confirm its skin benefits.

One of the standout features of ginseng is its ability to improve blood circulation and oxygen delivery to the skin, bringing a fresh supply of nutrients to support overall skin health. It also has antioxidant and anti-inflammatory properties. This helps to protect your skin against damage from UV exposure, pollution, and daily stress.

Additionally, studies suggest that ginseng may help reduce hyperpigmentation by inhibiting tyrosinase, the enzyme involved in melanin production.

There are different types of ginseng used in skincare, and while they all share core benefits, their potency can vary.

Most products use fresh or white ginseng because it’s more affordable. However, red ginseng, produced by steaming the root, contains higher levels of ginsenosides, which are compounds with proven anti-aging effects. These ginsenosides help reduce the appearance of wrinkles and improve skin elasticity.

Note: All forms of ginseng are listed simply as “Panax ginseng” in ingredient lists. We recommend reaching out to the brand if you have questions about which type of ginseng is used in their ingredients.

For general antioxidant benefits, any ginseng extract will do, but for wrinkle care or firmer skin, red or fermented ginseng is often more effective.

In short, ginseng is a powerhouse ingredient that supports hydration, radiance, and resilience.
