No, vitamin E does NOT improve scars. There is no scientific evidence confirming this claim. In fact, some studies do demonstrate vitamin E may cause skin irritation which actually worsen scarring. Anecdotal reports also mention widened scars after using vitamin e topically.
In this study (The Effects of Topical Vitamin E on the Cosmetic Appearance of Scars) the researchers concluded:
This study shows that there is no benefit to the cosmetic outcome of scars by applying vitamin E after skin surgery and that the application of topical vitamin E may actually be detrimental to the cosmetic appearance of a scar.
In 90% of the cases in this study, topical vitamin E either had no effect on, or actually worsened, the cosmetic appearance of scars.
So if vitamin E doesn’t work, what should we use?
The only proven effective scar treatment product you can use at home are Silicone Scar Treatment Sheets . (links to Amazon, read the reviews to learn how they can help you improve your scar tissue)
There are various studies demonstrating the benefits of silicone gel scar sheets. Here’s one published by Archives of Surgery.
Important to remark is that this modality does not work on all types of scars. Burn scars, discolored, and raised scars are known to improve. In some cases keloid scars may also be repulsed by silicones. Such scar tissue will become flat, softer, more pliable, and discolorations will tone down. Also itch and pain will be reduced.
Silicones have been used since the 1960’s in burn centers and hospitals. Only the last decades they have become available on the consumer market. Many people are still not aware of the existence (let alone effectiveness) of silicone sheeting for scars. Among those who are unaware of the benefits of silicones are not only consumers but also medical personnel. It’s a sad fact that many doctors, but even dermatologists, and plastic and cosmetic surgeons are not aware of the clinical proof that backs the use of silicones for scars.
For depressed scars silicones will not be the most appropriate treatment. These types of scar tissue will most likely be treated with fillers, dermarolling (needling), and collagen injections.
