This is the only vitamin C product I’ve actually noticed a difference in my skin with! If you’re not used to vitamin C on your skin I wouldn’t recommend starting with this one as even my skin which is used to vitamin C still tingled a bit when I applied it. The application is a bit odd, the texture is very unique, not really meant to be rubbed in a lot. I just place dots on my skin and gently glide my fingers around to spread it. It doesn’t pill for me which I was worried about. Anyways, as for the actual effect on my skin, it’s lightened my acne scarring and softened any fine lines on my face and my skin is glowing! Overall great vitamin C product.
