Ingredients Explained

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

Learn more about Diethylamino Hydroxybenzoyl Hexyl BenzoateGlycerin 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.

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.

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 Purslane, a succulent. It has anti-inflammatory, antioxidant, and hydrating properties.
Purslane is very nutritious. It contains omega-3 fatty acids, NMFs, many vitamins, minerals, and antioxidants. The vitamins found in purslane include: Vitamin C, Vitamin A, and Vitamin E.
Fun fact: Purslane is a succulent with an extensive habitat. It is used in traditional Korean medicine to treat irritated skin.

Learn more about Portulaca Oleracea ExtractEthylhexylglycerin (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.
Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.
This property also makes Pentylene Glycol a great texture enhancer. It can also help thicken or stabilize a product.
Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.
Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.
Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.
Learn more about Pentylene GlycolTocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

Round Lab Birch Moisturizing Sunscreen SPF 50+ PA++++ 40 ingredients
It's not the most hydrating sunscreen I've ever used and its texture is reminiscent of a slightly thick serum or an emulsion. It feels good on my skin and did not break me out. No white cast whatsoever, didn't require any blending in, and applied without a tacky finish. One of the sunscreens with the least pilling I've tried, but did very very very slightly pill on the area around the eyes after a Show more
Stung my face
I wanted to love it because so many people are praising it, but it just wasn't for me. I don't why, but it stung my face, and I'm not sure which ingredient is causing it (I don't have sensitive skin, but I used it alongside BoJ ginseng essence and iUnik centella calming gel cream in the morning, maybe the ingredients in the products react w each other?). It also makes me look oily, Show more
