Is there any medication/lotion that is good for getting rid of tiny scars from a surgery?

It depends: If your scars are relatively new (within 6 months), there is evidence that application of silicone sheeting or gel to the scar can help it fade. Silicone is more effective than vitamin e, aloe, etc. More recently, it has been shown that keeping a scar covered with paper tape also helps it fade. Photo is from patient who used silicone sheeting for 3 months.

Options: You cannot erase scars. Poor scars can be improved through the following methods: 1) scar massage 2) silicone sheeting (a kind of silicone tape you where over the scar) 3) steroid injections 4) laser treatment (helps remove coloring) 5) scar revision (removing the scar and starting over).
