You might be prone to keloid scarring. Those who are prone to keloid scarring develop surgical scars that are raised, darkened and permanently hardened.
It's been 3 weeks since surgery. The typical laporascopic surgical incision heals in 14 days or less, so you're beyond that timeframe. What you see is what you'll likely deal with long term.
You can use Ambi fade cream to lighten the incisions.
Nonetheless, scarring is a trade-off I happily accepted in exchange for being a normal-weight person who can maintain the weight loss. My scars, to me, are badges of honor.
Good luck to you.
