Hello, Thank you for posting on HCM. I appreciate your concern about acne scars. Acne scars are pretty challenging to treat and treatment comes with variable results. I would suggest you should consult a dermatologist, who would examine the severity and type of scarring and thus plan out the treatment protocol. I would suggest you to go for laser therapy (Fractional Co2 laser, Non-ablative RF etc) as it has the best results of all other treatment modalities. Moreover, if additionally treated with dermaroller or chemical peeling, pretty appreciable results can be achieved. Hexilak silicone gel is useful only for hypertrophic scars (scars which are raised about skin surface) Hope this will take care of your query. Wish you best of health. Thank you
