Like the common cold, quick weight loss and how to get six-pack abs without exercising, removing scars without surgery is a puzzle scientists have yet to unravel. You've heard about all sorts of natural cures, but the truth is, there isn't any solid scientific evidence to back up any of these claims. This goes for vitamin-enriched oils like vitamin D oil, as well as for D's close cousin, vitamin E oil. Using vitamin D oil on your scars probably won't harm you, but it probably won't help much, either. If you're determined to give it a try, speak to your doctor first about the possible side effects.
Vitamin D Oil
Vitamin D isn't normally available in oil form and is seldom found in a commercial solution that's made to put on your skin. This is primarily because the average person fills their daily recommended requirement of vitamin D by simply being in sunlight: the body synthesizes vitamin D when the skin is exposed to sun. If you inspect the supplement shelves at your local natural foods store, you'll find vitamin D supplements as liquids, tablets, capsules and included in multivitamins, but not as an oil. Dr. Dennis Gross Skincare sells a vitamin D oil that is advertised as being the first topical oil that allows you to absorb significant amounts of vitamin D through your skin. However, while the manufacturers say that using their vitamin D oil will moisturize your skin and help mask fine wrinkles, they do not claim that it can help with scar removal.
Vitamin D and Skin
According to MedlinePlus and the Mayo Clinic, vitamin D is commonly used to treat certain skin conditions. However, none of these include scar treatment. Calcipotriene and becocalcidiol, man-made versions of vitamin D, are used in prescription ointments to treat psoriasis, and vitamin D is used as a dietary supplement in the control of vitiligo, actinic keratosis and scleroderma, but these uses don't tell us that using vitamin D oil on your scars will make them magically disappear, or have any effect on them at all.
Possible Side Effects
While there's no reason you can't slather some vitamin D oil on your scars in the hope that it will do you good, you should know that some is likely to be absorbed through your skin into your bloodstream and that too much vitamin D flowing around in your system can cause problems. High amounts of vitamin D can cause your levels of calcium to rise, and that may spell trouble for people with lymphoma, heart disease or kidney problems. It can also cause fatigue, itchiness and muscle pain and can interfere with the proper function of medications like digoxin, atorvastatin, corticosteroids and diuretics.
Vitamin E Oil
Instead of vitamin D oil, many alternative medicine practitioners swear by vitamin E oil, recommending that it be applied to scars several times a day to help diminish their appearance or prevent their development entirely. As with vitamin D oil, though, clinical trials don't back this up. One study of vitamin E found that people who used a cream containing vitamin E for one year following surgery didn't have any different scars than people who used a cream without the vitamin added.
