I'm super vain, so I did a lot of research about how to prevent and reduce scarring. Only silicone tape or gel has been clinically proven to reduce scarring. If you do any research on plastic surgery, using silicone tape is almost universally recommended. It has a long history of being used on burn patients.
I used silicone tape, from Amazon. It was cheap, I still have tons left since you only use like an inch at a time, to cover all your little scars. I tried the gel, but it requires 2 or more applications a day. I'm too lazy for that. The scar tape last 3-6 days on me, through showers and everything.
