Tw:SA Will I be able to make this scars invisible?

I'm feeling really sad everytime I look at my harm I regret doing this so much it reminds me of a bad moment. Also I'm an adult with a job and it will be very embarrassing when I have to wear short sleeves during summer. I want to make them invisible, like gone ! Is this realistic expectation using just creams ? Is it safe I start using this scar gel ? Or should I wait longer to use it? They are one month. Looking for suggestions and also opinions on how much I can expect them to be invisible.
