Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Hyaluronic acid is naturally found in healthy skin. It is a humectant, meaning it draws moisture to your skin.
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:

It sits on the skin’s surface and primarily reflects and scatters UV light and also absorbs some of it.
This makes the line between “mineral” and “chemical” sunscreens a bit blurry, but in skincare labeling, Titanium Dioxide and Zinc Oxide are the two ingredients officially classified as mineral filters.
Because it’s non-irritating, Titanium Dioxide is often recommended for sensitive or acne-prone skin.
Thanks to modern production methods, nano-scale or fine-grade Titanium Dioxide is now widely used in cosmetics to reduce white cast and improve texture.
Despite its small particle size, studies show that Titanium Dioxide, even in nanoparticle form, is not absorbed into the skin.

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!

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.
