How Scar Healing Sheeting and Patches Work

Silicone sheeting and patches are clinically proven to be effective in the healing of a variety of scars and stretch marks. The most common scars are keloid and hypertrophic that form from surgery, burns, chemicals, wounds, and insect bites.

When will I see results?

In general, within 3 weeks you should see the color change in the scarred area. The silicone sheet/patch will begin to fade the reddish color and the skin will begin to go back to its original color.

In 3 to 6 weeks you should see the bumps or collagen start to flatten and eventually become completely flat.

These results differ depending on the size and age of the scar, and daily amount and consistency of the InvisiScar® treatment.

To ensure the best results follow these tips:

  1. Find the right size of sheeting for your scar. Make sure the size you choose is large enough for the area.
  2. Keep scarred area clean during application of treatment.
  3. Be consistent in the treatment. The more you wear the silicone sheet or patch, the better the results will be.

Exactly how the scar sheets work isn't fully understood. Theories include the creation of an environment for healing through moisture, decreasing the levels of the body's production of inflammatory substances and working on the body's collagen structure and production.


Silicone scar sheets are far from being a new treatment idea. The medical profession has been using them for many years in order to reduce the appearance of keloid and raised (hypertrophic) scars. They've also been used to prevent the formation of new scars following surgery. However, the availability to the general public for silicone sheets is a more recent development.


These sheets are coated on one side with silicone gel, and they come in a variety of sizes, some of which can be cut down to the size of the area being treated. Many of the products available are self-adhesive, while others have to be fixed with tape. Silicone sheets are reusable and can be washed.


These sheets have the approval of the US Food and Drug Administration (FDA) agency. In order for a product to gain this approval it not only has to prove it is safe for human use but that it is effective in some way.


Silicone scar sheets have a history of clinical study reaching back over more than 20 years and have been used extensively in hospitals and surgeries.


There is no doubt that when these sheets work, they work well. Raised scars can be improved in appearance in 85% of cases. Improvement seems to take anywhere between four to eight weeks in the best cases but can take up to three months and more.


Scar sheets need to be worn 24 hours a day for the best results and one of the main complaints leveled at the products is that they're difficult to keep stuck to the skin. The results in many cases are far from instant and some scars seem to be completely resistant to this type of treatment.


InvisiScar sheets and patches are completely safe to use and there are no complicated processes involved.


These sheets will not completely remove old scars but they have proven to be highly effective in reducing their appearance. It is always easier to treat new scars than older ones and it is recommended that sheets be used in the initial healing stages of wounds, but only once the open wound has sealed. Silicone sheets can't be used on open wounds.


As some of the other options for scar removal involve painful surgery and costly procedures, silicone sheets do offer a cheaper and clinically tested option.



The silicone patch has been clinically proven to show great results in the reduction of scar tissue.

Treatment of Hypertrophic and Keloid Scars with Silastic Gel Sheeting
Dockery GL, Nilson RZ Journal Foot and Ankle Surgery 1994 Mar-Apr; 33 2: 110

"An evaluation of the results of treatment of both fresh and long-standing hypertrophic and keloid scars on the lower extremities using topical SILASTIC Gel Sheeting was performed in 94 patients ranging in age from 11 to 73 years. In the total of 94 patients, there were 80 with true hypertrophic scars. Of this group, 74 patients (92.5%) were greatly improved with treatment, five patients (6.25%) were somewhat improved, and one patient (1.25%) was not improved . The remaining 14 patients in the study had true keloid scars, and their results were poorer with five patients (35.7%) greatly improved, five patients (35.7%) somewhat improved, and four patients (28.6%) showing no improvement. When all patients were totalled together, there were 79 patients (84%) greatly improved, 10 patients (11%) somewhat improved, and only five patients (5%) with no improvements. Overall, the success rate (somewhat improved to greatly improved) for the treatment of hypertrophic and keloid scars is high (95%) ."


Topical Silicone Gel Sheeting in the Treatment of Hypertrophic Scars and Keloids. A Dermatologic Experience
Gold MH J. Dermatology Surgical Oncology 1993; 19: 912-916

"Topical silicone gel sheeting has been used successfully in the management of hypertrophic and keloid scars resulting from thermal burn wounds.

METHODS: An open-labelled approach using the silicone gel sheets was performed using hypertrophic and keloid scars secondary to surgical procedures or traumatic insults.

RESULTS: The silicone gel sheets resulted in moderate improvement in scar thickness, scar color and was noted to be effective to some degree in all tested. The material was easy to use and painless.

CONCLUSION: Topical silicone gel sheeting is an effective method for the treatment of hypertrophic and keloid scars and may be considered useful in the treatment of these difficult cutaneous lesions."


Topical Treatments for Hypertrophic Scars
Zurada AB, Kriegel D, Davis I, Journal of the American Academy of Dermatology December 2006: 55: 6

"The therapeutic effect of topical gel sheeting on pre-existing hypertrophic scars is well documented. A number of controlled studies exist. For example, in a controlled trial of 20 patients who had either evolving hypertrophic scars or keloids, silicone gel sheeting stopped the development of and softened evolving hypertrophic lesions in 85% of cases. Silicone gel sheeting has also been shown to significantly improve elasticity of old scars between 1 and 6 months after treatment when compared with untreated scars."


Silicone Gel in the Treatment of Keloid Scars
Mercer NSG British Journal Plastic Surgery 1989, 42: 83-87

"The clinical effect of 0.6 mm thick silicone occlusive sheeting (SOS) applied over 32 hypertrophic and keloid scars was investigated. 88% of scars treated and followed up on showed distinct improvement. These results compared favorably to those published in other series."
