I like how this product fastly absorbed by my skin and it's not heavy on the skin. This is a great help with controlling my sebum production since I have a very oily skin. It also helps in lightening my darkspots and hyperpigmentations. This is my holygrail product that I would recommend to everyone.

When I first tried it, it kind of stings on my skin but it's tolerable, and after a few times of using it, it wouldn't sting anymore.

- Make sure to patch test first. - If you have a very sensitive skin I suggest to use a lower concentration of niacinamide like 5% or 2% because this one has 10%. - You will experience purging in this product but some people are not. So make sure to introduce it slowly by using it 2x a week only or mix it with your moisturizer. Use it 3x, 4x, and so on until your skin gets use to it. - Don't forget to use sunscreen everyday.
