If you read up about them on google it reckons that gel is better. However….. I also read that they did an experiment using people with 2 scars. One they used dermatix on and the other they just rubbed a placebo cream on. Dermatix stopped the itching and irritation BUT in both groups the scarring got better at the same rate. They concluded that just applying any cream had benefits on the appearance of scars. After reading that I decided not to bother buying it and will now just use bio oil once my wounds have healed!! Look it up before spending all that!
NOTE – I have no personal experience. Just read a lot through google search x
