Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
We don't have a description for Acer Saccharum Extract yet.
Allantoin is a soothing ingredient known for its protective and moisturizingg properties. Because of this, it is often added to products with strong active ingredients.
Studies show higher concentrations of this ingredient can promote wound healing.
Though it can be derived from the comfrey plant, allantoin is produced synthetically for cosmetic products to ensure purity.
Learn more about AllantoinThis type of green tea plant is native to China. It is closely related to Camellia sinensis. Both plants have very similar properties.
Camellia Oleifera Leaf is rich in antioxidants. It also has anti-inflammatory and anti-microbial properties.
Chamomilla Recutita Flower Extract comes from the Chamomile flower.
Chamomile is rich in antioxidants and has anti-inflammatory properties. Several compounds found in chamomile help with soothing, such as bisbolol.
Antioxidant components in chamomile make it an effective ingredient to help slow the signs of aging. Antioxidants help fight free-radical molecules, or molecules that may damage your skin.
Essential oils from chamomile have been found to improve wound healing due to its antimicrobial properties.
Ancient Greeks and Egyptians used Chamomile to treat skin redness and dryness. Chamomile has also been used to help treat stomach issues.

The bitter orange possesses antibacterial and antioxidant properties.
It can also be mildly exfoliating due to the citric acid, an AHA.
Citrus fruits are rich in flavonoids, alkaloids, and vitamin C.
Learn more about Citrus Aurantium Dulcis Fruit ExtractThis extract comes from cucumber. Cucumbers are mostly made up of water (95%), and the other 5% is composed of: vitamin C, caffeic acid, fatty acids, amino acids, and other minerals.
Cucumbers have anti-inflammatory, barrier repair, and hydrating properties.
They contain shikimate dehydrigenase, an enzyme shown to help reduce inflammation and soothe the skin.
The amino acids found in cucumbers help nourish our skin's natural acid mantle (it's an important part of our skin barrier). This slightly acidic film acts as a barrier to protect us from bacteria, viruses, and other contaminants.
Unless you have an allergy to cucumbers, this is generally a non-irritating ingredient.
Fun fact: Cucumis Sativus is native to South Asia and can now be found on every continent.

As a surfactant, it helps collect dirt and oils for washing. Emulsifiers prevent oils and water from separating.
Polysorbate 20 also adds scent to a product. Since it is made using sorbitol, it has a sweet scent. Sorbitol can also be found in fruits such as apples and peaches.
The lauric acid used to create Polysorbate 20 is often derived from coconuts.
Polysorbate 20 may not be fungal acne safe.
Learn more about Polysorbate 20This ingredient is also called sugarcane extract. It is a moisturizing humectant and has skin soothing properties.
Similar to hyaluronic acid, sugarcane can attract moisture to your skin.
Glycolic acid is a derivative of sugarcane. While glycolic acid is an AHA with exfoliating properties, sugarcane is not an AHA.
A study from 2021 found the compounds in sugarcane extract to have antioxidant, antimicrobial, and anti-inflammatory activity. The study also suggests these compounds can inhibit skin ageing enzymes and promote collagen synthesis.
Learn more about Saccharum Officinarum ExtractSodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
These are some other common types of Hyaluronic Acid:

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. Stay hydrated!
