Hi. Im Zack. I've Acne Problem Since 14 Years Old

Hi. im zack. i've acne problem since 14 years old and it become worst. Now, the acne slowly stop but it leave many deep scars all over my face. Currently, im using clobetamil G without any prescription from dermatologist to reduce the scars and it shows positive effect. However, based on my reading the product is not good for our skin. So, should i continue or discontinue the product ? and what are the other best product to remove acne scars ?
