Skin Conditioning, Solvent
Loved

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!

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.

Glycolic Acid is arguably the most famous AHA with a ton of research to back up its benefits.

Its main role is to remove the top layer of dead skin cells, allowing newer skin cells to emerge.

Specifically, AHAs work by breaking down the structural "glue" holding the old skin cells in place. Getting rid of the old skin cells allows skin to regenerate newer skin cells in its place. A build up of dead skin cells can lead to tired and dull looking skin.

Due to this, glycolic acid helps with:

Fun fact: Glycolic acid increases skin hydration by playing a role in creating molecules that create hyaluronic acid naturally.

When starting glycolic Acid, it is normal to feel slight stinging.

The pH value and concentration of glycolic acid play a role in the effectiveness of the product. Concentrations between 5-20% glycolic acid have been shown to be effective in clinical studies.

Recent studies have shown Glycolic Acid may protect the skin against UV damage. However, you should always wear SPF, especially when using exfoliants.

Panthenol is a common ingredient that helps hydrate and soothe the skin. It can be found naturally in our skin and hair.

This ingredient is also referred to as pro-vitamin B5 or dexpanthenol in dermatology.

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.

Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

My first chemical exfoliator. Great as an introduction for beginner or sensitive skin. Works well for a couple of months and then it didn't give the same effect as it used to. Help reduce blackheads, bumps, and prevent hormonal aches.

When I first used this, it made my skin tingle ever-so-slightly before revealing the smoothest skin ever. The ever-present texture (closed comedones) on my forehead and cheeks have diminished greatly because of this. I only use it at night because AHA can cause sensitivity to sunlight!
