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, Skin Conditioning, Skin Protecting

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

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.

Emollient, Skin Conditioning

Coco-Caprylate/Caprate is created from fatty coconut alcohol, caprylic acid, and capric acid.

It is a lightweight emollient. Emollients create a thin barrier on the skin to trap moisture in. This helps keep your skin hydrated and soft.

Once applied, Coco-Caprylate/Caprate is absorbed quickly and leaves a silky feel.

Coco-Caprylate/Caprate may not be fungal acne safe.

Buffering, Masking

Tromethamine helps balance the pH and improve the texture of a product. It is synthetically created.

As an emulsifier, Tromethamine prevents oil and water ingredients from separating. This helps stabilize the product and elongate a product's shelf life. Tromethamine also makes a product thicker.

Tromethamine helps balance the pH level of a product. Normal pH level of skin is slightly acidic (~4.75-5.5). The acidity of our skin is maintained by our glands and skin biome. Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.

Oral Tromethanmine is an anti-inflammatory drug but plays the role of masking, adding fragrance, and/or balancing pH in skincare.

1,3-Propanediol, 2-amino-2-(hydroxymethyl)-

Solvent

Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin. 

It’s often used to:

Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

Cleansing, Emulsifying, Skin Conditioning

Sodium Stearoyl Glutamate is an emulsifier and helps condition the skin. It is amino acid-based.

In higher amounts, it may act as a cleansing agent.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic polymer. It is used to thicken and improve the texture of products. Due to its properties, it can prevent water and oil ingredients from separating.

Antimicrobial, Antioxidant, Astringent

Camellia Sinensis Leaf Extract is derived from the leaves of the tea plant. Black tea, green tea, and oolong tea are all harvested from this plant.

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.

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

I bought it as a moisturizing and priming sunscreen for colder months, but even in winter it would make my skin so sticky and oily after a few hours. Moreover, during application the texture feels a little bit grainy even when shaken well before use.

If you use a toner and a serum underneath, get ready for pilling when applying makeup. I tried it with a lot of different serums and can tell that Show more

I enjoyed this sunscreen. My skin took to it very well and it is very moisturizing. I just wish it had a higher SPF, If you have dry or combo skin. I would give this a try.

I really wanted to love it!
I love the ingredients, the way it sits on my face, the dewiness it leaves on application, it even helps with the hyperpigmentation scars. BUT! It also makes me break out- which is such a bummer because other than that I really do love this product :(

BEWARE: I got a fake one from Amazon, it caused break outs on my skin and dried out during the day within few hours. The tube (packaging) is 100% aluminum and has a gloss pastel yellow packaging color. The fake one is plastic tube and has matt grayish yellow packaging color. See pictures in comparison (left is real and right is fake). Do not recommend buying it from Amazon at all.

Overall, I Show more
