How many applications does a 20g size have?

It depends on the size of the area being treated. I use a 1/2 pea size amount twice daily to cover a scar about a 1/4 inch long. The bottle lasts roughly 5-6 months.

How soon after my stitches removed can I start using biocorneum?

I waited until the scabs started to form and started applying right after. My scars are looking better and less noticeable after daily use for several months now.

How long should one use this product? Months? Years? I have a scar on my forehead due to a falling accident.

Per my Plastic Surgeon, scars are "forever treatable, however, the will never completely disappear". Scars are "searted", after one year. With that being said, if it is a new scar, I would start using it immediately and continue for one year or until satisfied with the results.I myself I have scars from a double mastectomy that I did not treat with this particular product until 6 months post surgery. I still today use this product and I am still seeing results the results in the color as the scars continue to fade away. November will be one year from that surgery. I am going to continue to use this scar cream until I can no longer see that is producing results, even if it's after 1 year. I also use this product on very old scars and still continue to see a difference in them as well, however, not as suddenly obvious as using on my new scars (less than 1yr)Also, the sun is a scars worst enemy! It will make it darker and more obvious, be it a fresh scar or a 10 yr old scar. Even if you purchase this product, I would also suggest applying additional sunscreen on top of it, once the BioCorneum has dried. I personally would purchase one with the highest SPF coverage possible (coppertone makes one for kids in SPF 90 that looks like a glue stick... works excellent and stays on!)

does it contain steroids?

Hi Patricia. Thank you for your inquiry. I have consulted with Dr. Freund and he states that there is no steroid in biocorneum products, just silicone and sunblock.
