Review title is helped brighten skin [SEP] I liked that it was unscented and the serum absorbed into my skin quickly. You have to activate the vitamin by plunging the top of the cap in to release the powder. The cap has a dropper in it to help control the amount of serum comes out. The serum was quite runny and it would drip off my hand so I had to cup my hand to prevent it from going everywhere. The bottle is small and is best to used up within 2 weeks. I ended up getting 3 weeks out of this bottle. I used it day and night and noticed my sun spots slightly lighten up. It didn't irritate my skin which I liked. I applied this after toning and before my sunscreen. Good stuff but dislike how runny it was, it was like water. The lotion I didn't care for to much but I like the pouch it came in. You can use it after to store another toiletries, etc.
