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!
Learn more about WaterNiacinamide 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.
Learn more about NiacinamideDimethyl Isosorbide is a solvent and helps deliver actives into your skin. It is created from sorbitol.
As a solvent, dimethyl isosorbide helps dissolve other ingredients. This helps ensure even distribution of an ingredient. It may also be used to decrease the thickness of a product.
Studies show dimethyl isosorbide is able to penetrate skin to deliver other ingredients into the skin, making them more effective.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Chlorphenesin is a synthetic preservative. It helps protect a product against bacteria in order to extend shelf life. In most cases, Chlorphenesin is paired with other preservatives such as phenoxyethanol and caprylyl glycol.
Chlorphenesin is a biocide. This means it is able to help fight the microorganisms on our skin. It is also able to fight odor-releasing bacteria.
Chlorphenesin is soluble in both water and glycerin.
Studies show Chlorphenesin is easily absorbed by our skin. You should speak with a skincare professional if you have concerns about using Chlorphenesin.

Gotta give credit where credit is due
WOW… lot of people ganging up on this incredibly affordable/popular serum. I understand the criticisms, but personally I don’t believe the intensity is warranted. For so many people this was the start of their skincare journey; it certainly was mine! And because I had never used ingredients like niacinamide or zinc on my face before, of course I noticed an Show more
(Tried Jan 2021) This was actually the product that made me realize that my skin does not mix with Niacinamide (especially at high concentrations because I can usually tolerate it at %4/less or when it isn't a primary ingredient). I tested it on my wrist and a small patch on my cheek to check, and I had hives in both areas. I wouldn't want to give this a poor rating solely on the account of my Show more
