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.

Ethylhexyl Triazone is oil soluble, oderless and colorless, which mean it is able to be incorporated into a variety of different formulations.

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 thought it was good for my skin since the ingredients have Niacinamide, but when i tried on it my skin the feeling is Silky and i was saying to myself that it's ok but in the morning I had a breakout like a small cyst then after a few days many are coming out on my skin face. The analysis of this website is really amazing. It's not Malassezia Safe, which tells me it's bad for the skin.
(Dry, dehydrated, aging, sensitive, rosacea. Climate with moderate humidity) I like this sunscreen. It has a pleasant consistency of a nourishing lotion, dries down within 10 min, and I quickly forget I’m wearing it. I work outdoor events frequently, and find this is good protection. I haven’t noticed any breakouts or irritation from it (unless I forget to wash it off at night).
