Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.
It is a:
- Humectant, drawing moisture into the skin
- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas
- Preservative booster, enhancing the antimicrobial activity of other preservatives
Acetyl Hexapeptide-8, commonly known as Argireline, is a popular peptide in skincare. It’s often referred to as a “Botox-like” ingredient because it helps reduce muscle movement.
By relaxing these micro-movements, Argireline may help minimize the appearance of fine lines and wrinkles. That said, it’s not as powerful as Botox, and research on its long-term effectiveness is still limited.
Beyond smoothing, Argireline may also support collagen production. Collagen is the protein that helps keep your skin firm, bouncy, and well-hydrated by strengthening the skin barrier.
So while Argireline isn’t a miracle fix, it can be a helpful addition to a routine focused on both prevention and skin health.

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.

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.
Learn more about GlycerinGlyceryl Stearate is a mix of glycerin and stearic acid.
It is used to stabilize the mixing of water and oil ingredients. By preventing these ingredients from separating, it can help elongate shelf life. It can also help thicken the product's texture.
As an emollient, it helps soften skin and supports barrier-replenishing ingredients.
In cosmetics, Glyceryl Stearate is often made from vegetable oils or synthetically produced.
This ingredient may not be fungal-acne safe
Fun fact: The human body also creates Glyceryl Stearate naturally.

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:
