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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

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.

Panthenol (also referred to as pro-vitamin B5) is a common ingredient that helps hydrate and soothe the skin.
lt is a humectant, meaning that it helps the skin attract and retain moisture.
Another benefit is the anti-inflammatory abilities. This means that it's great for sensitive, irritation-prone skin.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

Good but be careful with the eyes
Keeps the skin hydrated and plump but once I wasn't careful and sprayed too much so got into my right eye. I was out of home so had to run like Usain Bolt to the nearest fountain to wash my eye because it burned like hell 😭

I really wanted to like this, I love a lot of Rare Beauty products, however, I found that even after 1 use, it broke out my skin. I felt super oily and had several new pimples the next day. To be fair I had been trying some new products and some of the reaction could have been caused by the cumulative changes to my skincare routine. I also only tried it once. However, given the immediate oilly-ness and texture after using, I wouldn't recommend it if you have sensitive skin. Possibly might be better when using a very matte or dry power make up look.
