hello and welcome to HCM forum,
as you know keloids
keep recurring, and lasers are not the treatment for it.
cryo-gas/steroidal injections will take care of the keloid by reducing it in size and sometimes with regular sittings it resolves completely, but in some cases it reoccurs and you will have to undergo the same treatment again.
i would like to inform you that lasers and surgical excision can worsen the situation so do not go for them, rather apply steroidal creams /gels prescribed by your doctor.
i wish you good health.
