I have a dark and dull skin face. Sometimes it looks better after taking a bath or sleeping well but it will become the same (dark and dull) just after 10 or 15 minutes. Also, I have acne so I have many black spots in my face. My face looks terrible. I am very sad about this and almost loose my self-confidence. I heard that Revitol Brightener Cream was good and I am gonna use it but I would like to get some advice of you about this product. Does it really work (my skin is oil skin)? What should I do to improve my skin condition. Thanks very much.
