i can understand your concerns.
First of all i want to make it clear to you that keloids
proved to be resistant to treatmenty,although they can be made thin or less redened but canot be cured or removed completely.
I am sure your dermatologist
would have explained and tried everything before giving you the option of lasers.(pulsed dye lasers are relatively effective)
The problem with the keloids is if you remove them surgically you ll get a larger and thicker than the original one,otherwise surgical excison would have been a very good option.
Although i can make some recommendations to you,please do not do any skin surgery
,tattoes or body piercing because you already have a keloid so you are at risk to develop another one.
also if you have Acne
then you should immidiately see ur dermatologist to treat it there and then to avoid scarring.
I hope you ll find the information helpful.
