I bought this with the entire range when I first started using the whole range as it was highly recommended by the sales lady.
I didn't have any spots but I did have uneven skin tone and darker pigmentation around my mouth and on my forehead .

Its a soft gel like consistency that you apply before your moisturizer. It aids in clearing up uneven skin tone and spots .

Its very smooth and quick absorbing and does not leave any uncomfortable stickiness or residue on your face .

It is very effective as I definitely saw a positive difference in my skin . It works really well when used in conjunction with the rest of the range .
