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

Niacinamide has emerged as an all-star ingredient due to its many benefits.
It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.
Other benefits include smoothing wrinkles and minimizing redness.
The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

I was so excited to try a product with what seemed like no comedogenic ingredients, but I suspect all the extracts broke me out pretty badly. I’m talking deep, painful cysts. I think I saw a nice effect on skin brightness, but that’s the only upside unfortunately. This also left a chalky white residue at times.
I’m on my third bottle
Want a simple, hydrating, scentless, and affordable azelaic acid serum? Look no further! Azelaic acid is well tolerated by many and for me I’ve noticed great improvements regarding redness. There was a short period of time when I cut this out of my routine, and that’s when I noticed how much it had been doing to reduce redness in my skin. This serum also contains aloe Show more
