Can I use silicone from a hardware store on my face for acne scars?
No, the injection of industrial strength silicone in your face will cause a reaction caused granuloma formation or worse. Granuloma is a medical term for a tiny collection of immune cells known as macrophages. Granulomas form when the immune system attempts to wall off substances that it perceives as foreign but is unable to eliminate (http://en.wikipedia.org/wiki/Granuloma). This can turn into an abscess, boil or draining sinus which most likely will have to be surgically treated. That most likely would mean much worse scars on your face. Best,
