Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
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.

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.

This was one of the sunscreens I've been meaning to try since using The Round Lab Dokdo Sun Cream. I would say both have preformed similarly in regards to natural finish/ skin-like feel, but I found that this product has a faster absorption time in comparison. Overtime, I also thought it was nice that this sunscreen didn't exacerbate my oiliness or add to it, essentially had a mattifying effect. I Show more

This cleanser is amazing for brightening your face in the morning because it has vitamin C. I also use it in the nighttime cause it makes my skin feel refreshed. The only time I don't use this is when I am exfoliating with Bha, Aha.
It has a gel like feel and the bottle is big. If you are prone to Frangrance then you might want to be cautious.
Btw I have combo skin :)
Tried out this cleanser because I've seen good reviews on social media and love their sun screen. Unfortunately, I should've checked my compatibility with it before purchasing. Stuck with it for about a week and it made me breakout really bad, after each use my face still felt slightly oily like it didnโt help to cleanse away anything.
