According to the general public any scar products are thought to be effective. In fact many of these premises are incorrect. For more information on these so called effective remedies check out the myths page. Products that do work, and are clinically proven to work, are mentioned here.

Silicone Gel Sheets
These are self-adhesive sheets, patches, pads, or strips made of dimethicone silicone gel. There are some assumptions on their action but it remains unclear how they exactly work. They are referred to as ‘the golden standard in scar treatment’ by many cosmetic surgeons and dermatologists. But there are more tangible indications for being the best scar treatment product at the moment.  Clinical studies have proven silicone gel sheeting to be safe and superior to other occlusive dressings like polyethylene or polyurethane as well as other scar treatment products.

The silicone itself may also release some compounds into the skin that alter the way fibroblasts in the dermis generate collagen, Shim said.

Silicone Gel Ointments
These are in fact silicone creams. Some brands are Kelo-cote, Zeraderm and Dermatix? The big advantage the creams have over sheets is that they are far more convenient. They are sort of glued onto the scar tissue whereas the sheets, however self-adhesive, tend to let loose because of their weight. The creams are also far less noticeable which makes them more suitable for use out in the public. But a major disadvantage is the fact that the liquid version of silicone gel sheets is not as effective. My suggestion would be to use the sheets overnight and if possibly the cream in addition during daytime.

Moisturizing Scar Creams
Hydration seems to be very beneficial to improving scar appearance. Hydration is also one of the suggestions why silicone sheets are effective.

“We have found that the provision of support and hydration and especially in addition with an enhanced wound healing constituent acts together to provide surprisingly improved scar management and maturation”

None of the research done has shown any special scar cream to have benefits over petroleum based creams (e.g. Vaseline). In fact the petroleum ointment used as a controle factor in the study showed to have useful hydrating properties. That’s why Vaseline might be considered one of the best moisturizing scar creams at the moment. Another product renowned for its moisturizing action is Manuka honey or Manuka honey cream. This type of honey is also a very powerful wound care agent without side effects. There are even scientists who think it might work on scars as well. This has yet to be seen because no studies have been done.

Heat packs, Paraffin wax
Since an increased temperature in scar tissue has shown to improve its appearance heat application might be beneficiary. Heat packs and paraffin wax are common products used to implement heat application.

Manuka Honey for Wound Care
Optimal scar treatment starts with efficient wound care.  Manuka honey and products containing this powerful natural product have shown to be very beneficial to wound healing. Its anti-inflammatory properties are the most likely explanation for the reduction in hypertrophic scarring observed in wounds that were dressed with honey.

Centella Asiatica (Gotu Kola) for Wound Care
There is proof this herbal ingredient is able to boost wound healing and wound strenght. Whether it is actually helpful in treating scars remains to be seen. Its many medicinal properties sound promising though.
