Silicone Gel

Silicone Gel

What is it?

Silicone gel is a clear, self-drying gel. It is made from silicone. Research has shown that silicone can help to reduce the colour, height and texture of a scar. Silicone can also relieve itching and discomfort from your scar.

How does it work?

It is not clear exactly how silicone works. Some research suggests that Silicone creates a protective barrier over the scar. This allows the scar to mature while helping to prevent production of excess scar tissue. The silicone layer also assists with hydration of the scar.

Where can I get silicone gel?

There are many different brands of silicone gel available. Your therapist will assess which one is most suitable for your scar and demonstrate how to apply it by providing you with a sample. We request that your GP provide an ongoing supply. You will be given a letter to give to your GP requesting this. If this is not possible, you can purchase silicone gel yourself by ordering it on-line.

How do I apply silicone gel?

  • Ensure that the affected area is clean and dry.
  • Wipe off any excess cream if you have been using cream to massage.
  • Apply a very thin layer of gel, gently wiping over the scar twice to spread it evenly.
  • If you are using SilDermTMDual Action Scar Gel, use the roller ball to massage the gel into the scar.
  • Allow to dry for 4-5 minutes before putting on clothes or pressure garments.
  • Once dry, you can apply cosmetics or sunblock on top of the gel.
  • If it takes longer than 4-5 minutes to dry, you have used too much. Wipe off the excess and allow to dry.

How long should I continue to use silicone gel on my scar?

90 days is the recommended initial treatment period. However, you may be advised to continue to use it for longer than this by your therapist depending on the appearance and age of the scar.

How often should I apply silicone gel?

Apply the gel as frequently as your therapist instructs you to during the day after massaging with cream.
