Some researchers have used interferon, gamma, I think. Gel sheeting can work very well IF the treatment is used faithfully long term.
Pressure helps, as in hypertrophic burn scars or pressure earrings for earlobe keloids.
This is a liposomal extract of Centella Asiatica which has been found to be useful in a high percentage of patients. Compression in combination with this asiaticoside preparation may offer better results than occlusion with silicon sheeting. Ear lobe keloids need direct pressure - our experience seems to be less impressive with gweneralised pressure on the ear. Let us know if a ski mask works. I have a 17yowf with keloids on each earlobe.
