Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (Tinosorb M) is a hybrid and broad-spectrum UV ingredient. It is both a UV absorber and filter.
UV absorbers are an agent that absorbs UV rays. They protect your skin by using chemical reactions to convert UV rays into heat and energy. UV filters physically reduce the amount of UV rays from reaching your skin.
Tinosorb M covers a range of 280-400 nm and is photostable. This ingredient is neither oil or water soluble.
Tinosorb M, similarly to Tinosorb S, is not available in the US. However, it is available in the EU and Asia.

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 WaterDecyl Glucoside is a glucose-based surfactant. Surfactants help clean the skin by trapping oil, sebum, and dirt to be washed away.
It is created by reacting glucose with the fatty acids from plants.
Decyl Glucoside also helps stabilize the ingredients in a product by preventing them from separating.
This ingredient is biodegradable and non-toxic. This ingredient is commonly found in baby shampoos.
Decyl Glucoside is sometimes used to stabilize the UV filter Tinosorb.

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 help thicken or emulsify a product. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.
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.

On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.
Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

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 long day and some instances of aggressive rubbing. Slightly less glowy and lighter than the BOJ sunscreen.

This reef-safe chemical sunscreen stands out with its naturally glowy and non-greasy finish. It has the texture of a medium moist cream, spreads nicely and dries quickly in just a few minutes, making it easy to apply. It leaves no greasy or sticky residue, and there's no white cast or pilling to worry about. Notably, this sunscreen is highly moisturizing and can effectively replace the need for an additional moisturizer. It's my favourite one during the winter moths. However, I find it bit too moisturizing during the summer. Overall, it is an excellent choice for those looking for moisturizing sun protection without the drawbacks of a heavy or greasy sunscreen.
