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.
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.

Retinal has many benefits as other retinoids: improve skin texture, reduce large pores, reduce the effects of aging, reduce the visibility of dark spots, heal scars, and fight acne.
Studies show retinal may work at a faster rate than retinol due to its structure.
All retinoids have to be converted into retinoic acid before starting to work. Some retinoids take several steps of conversion before binding. Retinal is only one step away, making it more potent.
Like other retinoids, retinal may be irritating. It is best to ease into using this ingredient frequently.
Using the 'ramp up' method, start by using retinol once a week. This gives your skin time to adjust and decrease irritation. Once you feel ready, you can slowly increase the frequency of retinol use.
Using retinoids will increase sun-sensitivity in the first few weeks of use. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.

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!
