Hi, thanks for your question.
The essential ingredient in scar creams or treatments should be silicone, as it has actually been shown in studies to improve scars. This can be in the form of a cream that you place over the scar or you can use silicone strips. The strips can be very effective because they provide continuous contact over the scar.
It's important to not place these things on the incision until it is completely healed, which typically takes at least 2 weeks from surgery. Be sure to check with your surgeon about timing.
Another effective method of reducing scars is scar massage. Massage the scar with ointment or scar cream at least 3 times a day for several weeks. This will help it to lie flat.
All the best,
