Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning, Solvent

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!

Humectant, Masking, Skin Conditioning

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

  • It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
  • It is a humectant, which means that it helps attract moisture into the skin.
  • It helps improve product application.
  • It has mild preservative properties.

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Antioxidant, Perfuming

This tea tree oil comes from the leaves of the Tea Tree plant. Tea tree oil has antioxidant, anti-inflammatory, and antimicrobial properties.

According to the book Journal of Profiles of Drug Substances, tea tree helps in reducing acne-causing bacteria such as Propionibacterium acnes. This is due to the Terpinen components of tea tree oil.

Tea tree may cause sensitivity and irritation for some people. This oil naturally contains fragrance such as linalool and limonene.

However, research shows irritation usually occurs when using pure tea tree oil and not in cosmetic products.

Tea tree oil was found to help relieve the symptoms of psoriasis in one study.

Tea tree oil is toxic when ingested. Another study showed it to caused damage to the nervous system of dogs and cats when applied to their skin or given orally.

Emollient, Humectant, Skin Conditioning

Caprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.

It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.

Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.

This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.

Skin Conditioning

Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.

You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.

Buffering, Masking

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.

If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

Skin Conditioning, Solvent

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 

Disodium EDTA plays a role in making products more stable by aiding other preservatives.

It is a chelating agent, meaning it neutralizes metal ions that may be found in a product.

Disodium EDTA is a salt of edetic acid and is found to be safe in cosmetic ingredients.

You will find better things out there.

This wasn’t completely destructive to my skin back in my late teens (dehydrated oily-combo skin with hormonal acne I assume) but there’s a reason why I only aimed to finish my tube of this. Doesn’t cleanse very deeply so I felt I needed to use more product (I was oily, sweaty, and in a very place with very polluted air), and tends to leave me more dry Show more

works great on my oily skin, cleanses while not being stripping, so it doesn’t leave my skin feeling tight. 10/10 :)
