What is the Best Keloid Treatment?

Keloids can be very resistant to treatment. Treatment options can involve any of the following (and also involve combinations of the therapies listed below).
1. Steroid treatment - this usually requires multiple treatments. If the keloid is large enough this can leave excess skin after successful treatment. Steroid treatment can cause tissue atrophy and for african american skin or other darker skin types can also cause hypopigmentation.
2. Excision - While the mechanism for steroid formation is not fully understood wounds that have issues with contamination or infection may be at higher risk for keloid formation. Excising the keloid with a meticulous closure can effectively treat even keloids that have recurred.
3. Radiation - For extremely resistant or disfiguring keloids radiation therapy can be an effective mechanism to reduce recurrency rates in combination with surgical excision. I hope this helps.

These need a series of treatments including lasers, injections and sometimes surgery/radiation. Please see an expert. Best, Dr. Emer.

Thank you for your question and I am sorry that you have this concern. 
Keloid scars are a difficult condition to treat. Did you develop the keloid following a piercing or was it some other form of trauma? 
The options are based on a conservative approach initially and increasing the extent of intervention of the keloid depending on the result achieved. I break down the treatment options as follows:
In the first instance steroid injections are used. The theory behind steroid treatment is that it interacts in the wound healing pathway and interferes in collagen synthesis which is what is laid down to in healing wounds. An overgrowth of the scar results in a keloid scar forming. 
For small keloids, this can be quite effective. The injections are given into the keloid and you are seen at 8 weeks after injection. At this time, you might require further treatments. Most patients need atleast 3-4 injections for ear-lobe keloid scars.
IN addition, the use of silicone tape/ creams can help to reduce the scar. This needs to be worn/ applied for 23/ 24 hours of the day and treatment here is for a minimum of 9 months.
If they are resistant, then removal of the keloid and steroid injection is the next stage of treatment. The steroid can be given at the time of surgery or after the wound has healed. This again would require further steroid injections at regular intervals.
Compression dressings are very useful and tend to work well on ear-lobe keloids. These are placed wither after steroid injections or the surgery.
Cryptherapy has recently began to show some effective results in the treatment of keloids. This involves injection of the cryo into the keloid to aid intralesional injection. There are studies showing its effectiveness but it is still quite new in the treatment spectrum to know wha thte long term results would be. 
If despite this, the keloid still persists, or is increasing in size, then radiotherapy is a final option to try and reduce the scarring effect.
I hope this is helpful for you 
Kind regards
