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!

This serum is one of the best all-round anti-oxidant and dark spot serums containing:
- vitamin c
- Glutathion!!
- 5% niacinamide
- Q10
- Alpha Arbutin
(Unfortunately they removed TXA)
Skin type: combi acne prone
This is not just a dark spot serum, its a perfect anti-oxidant serum in the morning. Glutathion is a killer ingredient and the concentration of Vit C is low.

This is an okay serum for brightening. I have dry, eczema and rosacea skin and didn’t have any issues with breakouts or irritation BUT I didn’t see any big improvement either and used for about 3 months. I found that it left a slightly tacky feeling no matter how long I left between steps in my routine. No smells or fragrances so that was also a plus.
