Arnica gels and creams are good. (I apply one after my T shot.) However, it will be difficult to apply so soon after surgery, and nothing topical should be applied to the incisions until they are completely closed. Homeopathic pellets just go under the tongue (avoid touching them.) My surgeon had me take Arnica right before surgery and then every 4 hours post-op. It is *imperative* that you discuss this with the surgeon and anesthesiologist.
In terms of scar care, avoid the more expensive preparations like ScarGuard. They are the same thing as plain 100% silicone which you can buy for a fraction of the price, without the other additives that do nothing for scars. Plus, what's being rubbed into scars is actually less important than the action of massaging them.
