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.

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.

AHHHHHH!!!
Let me start out by saying I don’t think I have sensitive skin. I can put up with pretty strong prescription stuff like clindamycin...
AHHHHHH!!!
Let me start out by saying I don’t think I have sensitive skin. I can put up with pretty strong prescription stuff like clindamycin phosphate solution (which is 50% alcohol) or tretinoin at .05%. BUT this toner… oh my gosh. “Tingling” I guess is just a nice way of saying this stuff BURNS! And I tried this before getting the prescription strength stuff I just mentioned, so I know my skin barrier wasn’t already going through it or something like that. The only people I would recommend this too are those who are 100% confidant they have oily skin of steel. Looking at the ingredients (BHA, AHA, PHA, sulfur) I imagine this would knockout your acne… If you can handle it that is. But I think this stuff is just too strong for most people. Plus it's kinda up there in price, so I personally cannot say I recommend this product. There's definitely better, more affordable options out there.
