Ingredients Side-by-side
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!

Commonly found in sunscreens, Ethylhexyl Salicylate is created from salicylic acid and 2-ethylhexanol. You might know salicylic acid as the effective acne fighter ingredient and BHA.
The ethylhexanol in this ingredient is a fatty alcohol and helps hydrate your skin, similar to oils. It is an emollient, which means it traps moisture into the skin.
According to manufacturers, Ethylhexyl Salicylate absorbs UV wavelength of 295-315 nm, with a peak absorption at 307-310 nm. UVA rays are linked to long term skin damage, such as hyperpigmentation. UVB rays emit more energy and are capable of damaging our DNA. UVB rays cause sunburn.

The sunscreen has a very watery consistency (as the name would suggest) leading to it feeling weightless on the skin, it applies beautifully without any white cast, and is cosmetically brilliant under makeup. BE WARNED, this product has a noticeable sunscreen scent that depending on what you’re used to may or may not be tolerable. This sunscreen also has significant shine, it’s perfect for my dry skin as it leaves me with a dewy finish that I appreciate, however anyone desiring a matte finish or those with oily skin will definitely not like this product.

sosososoo good!! has so many nice ingredients that hydrate your skin and also protects it from UV rays. And i can't get over how GOOD this works...
sosososoo good!! has so many nice ingredients that hydrate your skin and also protects it from UV rays. And i can't get over how GOOD this works under makeup it's insane, no pilling no white cast, just a great subtle glow and quick drying with no fragrance.
Edit: Felt like adding something, even if this went more viral around 2021 and other more viral sunscreens have come out since then, i've still been coming back to this one because it's just so simple and yet so effective.
Great for my sensitive combo skin and for people that don't have much time in the AM since it can kind of double down as moisturiser <3
