Some key points by Dr. Adrian Richards about keloid and hypertrophic scars and about scar treatment options:

– Hypertrophic scarring occurs within the normal scar, is limited. Hypertrophic scars tend to get better with time.

– Keloid scars occur in people with darker complexion, and can be started by minor trauma, like piercing or ingrown hair. Keloids grow outside the area of the original scar.

Treatment options: massage; next stage: you can use silicone gels (like Strataderm, Dermatix) or silicone sheets (Cica Care); next stage: steroid injections. Keloid scars are more difficult to treat. Another option for keloids is radiotherapy.
