This is a very lightweight and gentle vitamin c serum. It is a very thin consistency and applies on the face well. I've tried vitamin c serums in the past that was quite harsh and irrated my skin but this one is great! Im sticking to it. Ive been using it for a month and i've seen my acne spots and pigmentation reduced and has been lightening! It's so affordable compared to the other ones too! It also has a citrus/orange scent but I dont mind it!
