Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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!

It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.
Learn more about PropanediolPolysorbate 20 is made by combining ethoxylation of sorbitan, ethylene oxide, and lauric acid. It is a mild cleansing agent, surfactant, and emulsifier.
As a surfactant, it helps collect dirt and oils for washing. Emulsifiers prevent oils and water from separating.
Polysorbate 20 also adds scent to a product. Since it is made using sorbitol, it has a sweet scent. Sorbitol can also be found in fruits such as apples and peaches.
The lauric acid used to create Polysorbate 20 is often derived from coconuts.
Polysorbate 20 may not be fungal acne safe.

Not good for me
I have dry skin and I thought this product would be great for me. It burned a little bit and broke me out like crazy after a few days of using. I gave it to my mom and it worked for her. Do not buy this if you have sensitive skin.
a thin, oil-like serum- do not buy if you hate any sort of greasy-like feeling. Worked amazing with my combination skin, especially through winter on any dry patches. Did not break me out and helped my skin to appear brighter and more even. While it is an oil based serum, it absorbs nicely and layers well with other serums considering they aren’t overdone.

Skin type: Combi Acne Prone
I like this booster but not adore it. It can be combined with almost anything and does the job alright. It contains Matrixyl 3000 which is nice and has a compact ingredient list. However, in general I would choose The Ordinary Buffet over this one since it works better IMO.
