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 WaterDipropylene Glycol is a synthetically created stabilizer and solvent. It is a part of the glycol class in the alcohol family.

Panthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.
There are two forms of panthenol: D and L.
D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.
Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):
Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.
This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.
This ingredient is also referred to as pro-vitamin B5.

Lavender imparts a famous scent. While the smell is lovely, this ingredient and may sensitize skin in topical products. This is because it contains linalool, a known allergen.
However, lavender essential oil has shown to have anti-inflammatory activity due to its prostanoid and histamine content. Its leaves also exhibit antibacterial properties.

Some animals, plants, and bacteria create trehalose as a source of energy to survive freeze or lack of water.
