Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.
Diethylamino 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.

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.

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.

COSRX Aloe 54.2 Aqua Tone-up Sunscreen SPF 50+ PA++++ 40 ingredients
love this sunscreen! its so light and moisturizing and is far from irritating. chemical sunscreens are always the way to go if you want effective and comfortable sun protection. i will say its definitely formulated for fair skin as a tone up cream, so treat it like a tinted sunscreen. leaves a crazy "white cast" when i have a tan so keep that in mind.
Biore UV Watery Gel Sunscreen SPF 50+ PA++++ 36 ingredients
New formula has tone-up and I dont like it.
I had used 3 bottles of this in last couple of years. But the one I bought in 2023 has tone-up and it has quite sticky texture to touch. My skin is super oily and has yellow complexion, that's why I don't want tone-up. Overall, it is still a very good product.
Best Sunscreen
Provides ample skin protection and coverage, pleasantly melts into skin and leaves no stickiness and discomfort of something being on the face. Easily applied all over with watery gel texture. Pleasant smell that does not overwhelm and fades, with no irritiation. Also very affordable.
