Ingredients Explained
These ingredients are found in both products.
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.
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!
Learn more about WaterSynthetic Wax is created from fossil fuels such as natural gas. It is used to enhance texture, adjust pH, and as an occlusive.
It may also be used as an abrasive ingredient to exfoliate the skin.
Synthetic Wax may not be fungal acne safe.
Learn more about Synthetic WaxDiethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a chemical UV-A absorber. It is formulated for high UVA protection (320-400 nm).
DHHB is well-liked for:
DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%. Unfortunately, it has not been approved for use in the US or Canada due to slow regulatory processes.
This ingredient is soluble in oils, fats, and lipids.

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.
You might know this ingredient as Tinosorb S or Bemotrizinol. It is a UV filter that covers both UVA and UVB rays.
This ingredient has two peak UV absorption peaks ( 310 and 340 nm) and is able to absorb both UV-A and UV-B rays. This ingredient works by preventing UV rays from reaching and damaging your skin.
On top of that - it is highly photostable and helps prevent the photodegration of other sunscreen ingredients such as avobenzone.
Tinosorb S is allowed in the EU, Australia, and Asia. It is close to being approved by the FDA and we'll hopefully get this ingredient in the U.S. by late 2025.
Fun fact: Tinosorb S is the most effective UV absorber at maximum concentration (measured by SPF) permitted in the EU.
This ingredient is oil-soluble, so your oil-cleansers will take this right off at night.

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.

Fun fact: This ingredient is used in traditional Asian medicine.
Learn more about Ulmus Davidiana Root ExtractAloe Barbadensis Leaf Extract is an extract of the leaves of the aloe, Aloe barbadensis, Liliaceae.
You may know Aloe to be a good sunburn reliever and inflammation reducer. This is because it contains many components that are known to help reduce irritation and itchiness. These include vitamins, amino acids, polysaccharides, and more. The high water content of aloe also helps give a cooling effect.
Aloe contains the antioxidants Vitamins A, C, and E. These vitamins neutralize free radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.
The aloe plant is naturally abundant in polysaccharides, a carbohydrate made of sugar molecules. Polysaccharides help hydrate your skin by mimicking your skin's natural carbohydrates.
As it is easily absorbed by the skin, aloe is a great moisturizer. It is both a humectant and emollient. Emollients help trap moisture in your skin, keeping your skin soft. Humectants draw water from the air to your skin.
Other components of aloe include sugars such as monosaccharides and polysaccharides, folic acid, choline, many common minerals such as calcium, fatty acids, amino acids, and Vitamin B12.
Aloe does not protect against UV rays, despite it soothing sunburns.
There are over 420 species of aloe but Aloe Barbadensis is the most commonly used for topical products.

Round Lab Birch Moisturizing Sun Stick SPF 50+ PA++++ 51 ingredients
Love, love, LOVE this sunscreen stick. It glides on smooth, doesn't feel oily, goes on invisible, and feels so moisturizing. I will say, it does sting open wounds on the skin, I think it's probably the birch, so I'd be careful applying this on open acne marks. But overall, it is the best sunscreen stick I've tried, and is so easy to pop into a purse to carry for easy reapplication of sun Show more
pretty great sun stick. it has a nice texture. however, when reapplying over makeup, it does seem to make your makeup very streaky. if you’re using this out in public for reapplication over makeup, i’d advise bringing a makeup brush so that you can fix the streaks.
