Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
Learn more about Butylene GlycolThis 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.

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.

Hordeum Vulgare Extract is an extract of barley, the same grain used in beer and bread.
In skincare, it is a skin conditioning and hydrating agent. This ingredient contains polyphenols, vitamin E, and trace minerals like zinc, copper, and selenium that help neutralize free radicals behind oxidative skin stress.
Lab studies on human skin cells show it can support the skin barrier, boost cell survival, and speed repair after UV exposure.
The Cosmetic Ingredient Review Expert Panel has reviewed 16 barley-derived ingredients and concluded they're safe as used with the highest reported use concentration being 1.5% (in leave-on body/hand products).
Patch testing has also found it not to be a skin irritant or sensitizer at cosmetic levels.
However, barley is a recognized food allergen so people with a known barley/grain allergy should approach it cautiously.
Note: This ingredient is not gluten-free for those avoiding gluten for skin-contact reasons.

It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome.
On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive.
Another perk of this ingredient is that it stays functional across a wide pH range (3-10).
You'll often see it paired with boosters like Ethylhexylglycerin; one study showed that a 1:9 ratio of Ethylhexylglycerin to Phenoxyethanol damages bacterial membranes as effectively as doubling the Phenoxyethanol concentration on its own.
Typical use concentrations range from 0.3-1% depending on the formula, and this ingredient is capped at 1% int the EU.
Safety-wise, the fear mongering does not hold up to the evidence. The EU's Scientific Committee on Consumer Safety and FDA consider it safe as a preservative at up to 1%, including for children of all ages.
Adverse systemic effects only showed up in animal studies at exposures roughly 200x higher than what people get from cosmetics. And despite its very widespread use, this ingredient is a rare sensitizer and allergic reactions are uncommon.
Learn more about PhenoxyethanolPropylene Glycol Dicaprate is an emollient and emulsifier. It is created from a mixture of fatty acids.
Sesamum Indicum Seed Oil is the cold-pressed oil from sesame seeds.
It is an emollient and skin conditioning agent made up of roughly 82-85% unsaturated fatty acids, mostly linoleic (~41%) and oleic acid (~39%).
This pairing gives it barrier-supporting and moisturizing properties. Linoleic acid, an essential omega-6 fatty acid, can be incorporated into complex skin lipids. Topical application has shown barrier repair, anti-inflammatory, and wound-healing effects in cell and animal studies.
Beyond fatty acids, sesame oil brings something more distinctive to the table:
It contains natural antioxidants sesamol, sesamolin, and gamma-tocopherol. These also give the oil notably high oxidative stability.
One of the oil's key lignans, sesamin, has also demonstrated anti-inflammatory activity in preclinical models.
A 2023 clinical study found that a single application of sesame seed oil to the forearms of 35 healthy women improved stratum corneum hydration (though it didn't outperform raspberry seed oil).
The comedogenic rating of 1-3 depends on the type of sesame oil; unrefined carries a rating of 3 while refined sesame oil drops to a 1.
This ingredient may not be safe for fungal acne as it contains fatty acids that can feed Malassezia.

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.
Learn more about Sodium HyaluronateStearic Acid is a fatty acid that is already found in your skin. It's one of the free fatty acids that works alongside ceramides and cholesterols to maintain your barrier.
In cosmetics, it is a multitasker:
Safety-wise, the CIR Expert Panel has concluded it to be safe in cosmetics when formulated to be non-irritating and non-sensitizing.
Free stearic acid is a C18 fatty acid that the Malassezia yeast can substrate, so this ingredient may not be fungal acne safe.
