Ingredients Explained
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!
Learn more about WaterLinoleic Acid is also known as Vitamin F. It is a fatty acid with emollient and skin conditioning properties.
Our top layer of skin, or epidermis, naturally contains high amounts of linoleic acid.
Your body uses linoleic acid to build ceramides and prostaglandins. Ceramides keep your skin's barrier hydrated and strong while prosaglandins help control inflammation and healing.
Needless to say, linoleic acid is crucial for having a strong skin barrier.
One study found applying linoleic acid rich sunflower oil to be more effective at repairing the skin barrier than olive oil.
This ingredient can also help treat acne by softening sebum to prevent clogged pores. Another study found using 2.5% linoleic acid gel for 4 weeks showed a 25% reduction in small comedones.
Studies show it can also help lighten hyperpigmentation or sun spots by disrupting the melanin production process. It also helps your skin shed melanin pigment from your skin caused by UV exposure.
Due to its role in the production of the fatty acid prostaglandin, linoleic acid can also help reduce inflammation and support wound healing.
Fun fact: Linoleic acid is an essential fatty acid. This means our bodies cannot create it on its own and we need to get it through foods such as nuts and vegetable oils.
Just know this ingredient is not always fungal-acne safe because it is a long-chain fatty acid (with 18 carbon atoms) that directly feeds the Malassezia yeast responsible for fungal acne.
Learn more about Linoleic AcidOenothera Biennis Oil (aka Evening Primrose Oil) is a non-fragrant oil from the evening primrose. Like other botanical oils, it is an emollient that helps hydrate and nourish skin.
It has an interesting fatty acid profile: linoleic (70-74%) and γ-linolenic (8-10%), with some amounts ofoleic palmitic, and stearic acids.
The gamma-linoleic acid (GLA) is the headliner here; it's relatively rare in plant oils and acts as a precursor for anti-inflammatory signaling molecules in the skin.
There's a mixed body of clinical research with this ingredient as well, mostly on eczema/atopic dermatitis skin.
Some controlled trials showed improvement in inflammation, dryness, scaling, and overall severity. Other studies and large meta-analysis failed to show a significant effect; the honest takeaway here is "promising but inconsistent" rather than "miracle oil".
On the safety front, this ingredient is found to be safe as used in cosmetics and even has a history of safe food use.
Since this oil is contains oleic acid and palmitic acid, it may not be fungal acne safe. The Malassezia yeast feeds on fatty acids with carbon chain lengths between C11-C24. Oleic Acid sits at C18 and Palmitic acid sits at C16.
In vitro studies have shown that oleic acid and palmitic acid are some of the fatty acids that induce rapid Malassezia growth in lab settings.

Cinnamomum Cassia Bark is also known as cinnamon. It contains a bit of iron, calcium, and magnesium.
No studies support the use of cinnamon in skincare. In fact, it is considered a skin irritant and allergen.
Cinnamon bark contains Cinnamal, a known allergen and skin irritant.
Studies do show using cinnamon can induce:
The bottom line: Avoid topical cinnamon (but eating it can provide health benefits!)

Carbomer is a high-molecular weight polymer of acrylic acid. It is used to form gels and thicken formulas.
Due to its large molecular size, carbomer has minimal skin penetration and is considered an inert ingredient.
A high amount of carbomer can cause pilling or balling up of products. Don't worry, most products contain 1% or less of carbomer.

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
Caprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created.
Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin.
Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on).
