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 WaterTitanium dioxide is known for its UVA and UVB protection properties. It is non-comedogenic and non-irritating. Titanium Dioxide is a physical sunscreen. Physical sunscreens reflect light and prevent it from reaching your skin.
Protecting your skin against UV radiation can prevent the signs of aging. Sun damage is associated with fine-lines, wrinkles, loss of firmness, and hyperpigmentation. Titanium dioxide can help prevent premature aging.
With modern production, nano-scale or fine-grade titanium dioxide can be easily produced for cosmetics. In sunscreen, titanium dioxide absorbs UV light. Our skin is not able to absorb Titanium dioxide, even nanoparticles.
Titanium itself is the 9th most common element in the Earth's crust. Titanium dioxide is formed when oxygen is introduced and can be found in ores, dust, sand, and soil.
Pure titanium dioxide is a white powder that is used in many products to add or change color.

Today, traditional and nano-sized zinc oxide can be found in beauty products. Nano-sized zinc oxide can enhance a product's UV protection. While it is not believed to have a negative effect on skin, nano-zinc oxide may be harmful to coral reefs - though the verdict is not entirely out on this one.
Zinc Oxide also has antibacterial and calming properties. It is not water soluble.
Zinc has been used throughout history as an ingredient in paint and medicine. An Indian text from 500BC is believed to list zinc oxide as a salve for open wound. The Ancient Greek physician Dioscorides has also mentioned the use of zinc as an ointment in 1AD.

This ingredient helps hydrate, soothe, and protect the skin.
What makes hyaluronic acid so hydrating? It has the capacity to bind or hold large amounts of water.
Fun fact: It is already naturally found in our bodies, such as the fluids of our eyes and our joints.
Studies find this ingredient to have anti-inflammatory and anti-microbial properties. This can help speed up wound-healing.
Hyaluronic acid can be irritating if the molecule has a low-molecular weight, or if the molecules are small.
One study found low-molecular weight hyaluronic acid to be pro-inflammatory, meaning some people may experience irritation. This is because our bodies use hyaluronic acid in the wound-healing process to signal to our bodies, via irritation, that something needs healing.
The same study found high-molecular weight hyaluronic acid to be anti-inflammatory.
These are some other common types of Hyaluronic Acid:

Quite a moisturising SPF and works well as a makeup base. Hasn't pilled for me at all. The texture is similar to the Bondi Sands in the white tube but thicker. If your skin is prone to clogging I would be a little hesitant - although I can't say this has actively caused breakouts, it feels like it could contribute towards pore clogging you don't thoroughly clean/exfoliate your skin.
after trying so many spfs my long search for the perfect sunscreen is seemingly over, i can't stress enough how much i like this product.
it has a mousse-like texture that feels weightless when applied and it uses a mixture of chemical and physical spf filters, combined with hyaluronic acid for a bit of hydration. it has a lovely satin finish and doesnt pill when layered on top of other Show more

The INCI seems great on paper and it actually feels pleasant on the skin but unfortunately, my skin was burning at the end of the day and it was red and irritated each time. It even gave me small whiteheads that seemed to be those typical whiteheads one gets from irritation (I never get them otherwise, not my type of acne). I then checked out what's up with alpha-arbutin. All online sources I came Show more
