I haven't been using this product for a month yet and I've already seen a dramatic difference - my skin is glowing! And it's all thanks to adding this serum to my daily skin care routine. It's awesome for sensitive skin and is quick-absorbing. Non-irritating and calms my skin making it appear more even-toned and radiant. My skin usually gets oily throughout the day but not anymore when I use this product. A definite must-have! I don't typically use serums, but I will be purchasing this in the future for sure. It's also vegan friendly and cruelty free!
