Is Contractubex Safe for Removing Acne Scars?

I am male, 31 years old. I have had a problem with acne vulgaris and nodular acne for 14 years and now, I have acne scar and its making me self-conscious. I'm seriously considering using Contactubex to lighten the scars but I'm not sure of the results. Are there side effects? Please advice.
