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!

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

  • It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
  • It is a humectant, which means that it helps attract moisture into the skin.
  • It helps improve product application.

Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.

Cucumis Sativus Fruit Extract comes from the cucumber. Cucumis Sativus is native to South Asia and can now be found on every continent.

Cucumbers are mostly made up of water (95%), and the other 5% is composed of: vitamin C, caffeic acid, fatty acids, amino acids, and other minerals.

Cucumbers have anti-aging, anti-inflammatory, and hydrating properties.

Vitamin C and Caffeic acid are potent antioxidants that may help with anti-aging. Antioxidants help neutralize free-radical molecules, or unstable molecules that may damage our skin cells and DNA.

Cucumbers contain shikimate dehydrigenase, an enzyme shown to help reduce inflammation and soothe the skin. The amino acids help nourish our skin's natural acid mantle. Our acid mantle is formed from the mixing of sebum and sweat. This slightly acidic film acts as a barrier to protect us from bacteria, viruses, and other contaminants.

Unless you have an allergy to cucumbers, it is generally a non-irritating ingredient.
