Essential Oil Formulas for Heaing Wounds and Scars
At one time or another, many of us have accidents or surgery that can result in unsightly scars. The same can happen from difficult cases of acne. Even stretch marks from pregnancy or significant weight loss can leave permanent unsmooth textures on the skin. There are few treatments available beyond silicone patches, and these won't work in all cases. If one is looking for a natural means to improve skin appearance as a wound heals, or to smooth old scars or stretch marks, scientific aromatherapy literature provides some formulas that may help.
The Essential Oils
There are a few primary essential oils used in skin care which offer their regenerative properties; these oils can be used in low concentrations, and are generally well-tolerated -- certainly more so than many synthetic ingredients. The most important of these may be Helichrysum italicum, also known as Everlasting oil. This wonderful oil is distilled from the daisy-like flowers of the herb. It has a lovely earthy aroma and, despite it's apparent expense, works in very low concentrations (only a few drops per tablespoon of your total blend). Helichrysum is strongly anti-inflammatory and contains powerful regenerative molecules unique to this oil only.
Helichrysum, the Healing Foundation
Helichrysum essential oil is the cornerstone for many blends for healing the skin, and is the only one truly necessary for supporting currently healing skin damage - it should be used at appropriate concentrations with Rosehip Seed, Tamanu and Hazelnut oils, as mentioned later in this article. As noted by well-known aromatherapist Kurt Schnaubelt, "The triple unsaturated fatty acids (of Rosehip Seed oil) strengthen the cell membranes and, combined with the regnerative qualities of Everlasting oil (Helichrysum), heal wounds with minimal or no scarring".
Synergizing with Lavender
As mentioned above, Lavender is often included in skin care blends - it has gentle anti-inflammatory and tissue regenerative properties, along with very soothing, anti-anxiety aroma. This stress-relieving action seems to be imparted even at the cellular level where wound healing occurs. Lavender essential oil itself began the modern aromatherapy revolution when a scientist burned his hand in a laboratory accident, and after cooling the wound in a beaker of Lavender found the wound to heal remarkably quickly. It is also thought to 'synergize' or improve the efficacy of other essential oils in combination.
Salvia Officinalis: Sage for Old Scars
Next up is the essential oil distilled from the leaves of common Sage, or Salvia officinalis. Sage is used in low concentrations in very specific conditions - where the scars are old and require a little extra phytochemical power to heal. Sage oil can bring circulation to the area, and can assist the scarred area of the skin to regenerate, particularly in concert with other oils. Sage can be used in stretch mark formulas, but should only be employed post-partum because of the high thujone content of the oil.
Rosemary to Stimulate Cellular Metabolism
Rosemary of the Verbenone chemotype (rather than Cineol, which does not have the same properties) contains regenerative ketones like Lavender and Helichrysum, plus has the added benefit of stimulating the skin's metabolic process. This oil can bring greater circulation to skin tissues, delivering nutrients and eliminating cellular waste and toxins -- functions which are crucial during the healing process. Rosemary Verbenone can be used for healing new or old wounds.
Carotenoid Containing Essential Oils Speed Healing
Other essential oils can offer important nutrients that may speed the healing process. Most importantly, they offer carotenoids and carotenes -- natural vitamin-A-like compounds needed for increasing the strength of the healing tissue. Vitamin A is considered absolutely critical to normal skin development, and indispensable during wound healing. Carotenoids are also strong antioxidants, which can 'mop up' free radicals at the site of an injury. Two essential oils can be chosen from: Sea Buckthorn and Carrot Root. These are both found as Supercritical Carbon Dioxide extracts with deep colors, indicating the high levels of nutrients.
Tea Tree: Nature's Finest Antiseptic
For wounds that are currently healing, a small amount of an antiseptic essential oil can help the process. It can prevent redness and irritation that is the result of your body dealing with bacteria at the sight of the injury. Lavender and Rosemary do have some antiseptic properties, and may be enough if you feel the wound has been well-cleaned. For stronger antiseptic activity, 1-5% Tea Tree essential oil can be added to any recipe. The use of the Tea Tree can be discontinued once the wound has sealed completely. If you're really not fond of the aroma of Tea Tree, Palmarosa essential oil can be used as a more mildly-aromatic substitute.
The Carrier Oils: Diluting and Delivering the Essential Oils
All these oils but Lavender should be diluted in a carrier before use (Lavender CAN be used directly on the skin, but will be used in diluted form in the following blends). Many studies have shown the great efficacy of essential oils at low concentrations - so in Aromatherapy, 'less is more' is a general rule. Two highly regarded carrier or 'base' oils used for skin treatment are Rosehip seed, cold-pressed from a plant native to the mountain regions of South America, and Hazelnut oil, which is suitable for all skin types. These oils will help the essential oils absorb into the skin, and can provide their own nutritive properties. Rosehip seed contains a wealth of fatty acids, plus a compound similar in action to the pharmaceutical preparation 'Retin A'. without the drying side effects. Hazelnut oil has mild astringent properties, and will not leave the skin feeling greasy. It is appropriate even for acne prone skin (where Rosehip seed is not!). Other useful healing carrier oils are Tamanu Nut -- recently making waves as an excellent carrier for healing nearly all types of skin conditions -- and Evening Primrose, which offers nutritive and anti-inflammatory fatty acids.
Putting It Together: The Recipes
For effective wound healing of recent cuts and scrapes (and has been used successfully on surgical incisions), to 1 ounce Tamanu Nut oil (also called Callophyllum) and 1 ounce Rosehip seed oil add 1 milliliter of Helichrysum essential oil, 1 milliliter of Lavender essential oil and either 1 milliliter of Sea Buckthorn or 3 milliliters of Carrot Root CO2 extracts - apply twice a day for 7 to 10 days. For older scars from wounds or acne, including keloid scars, replace the Lavender in the previous recipe with Rosemary essential oil or Sage essential oil (not to be used during pregnancy). Where acne can reoccur, do NOT use Rosehip seed -- instead use Evening Primrose or Hemp Seed oils. Apply regularly for 3 to 6 months. For the healing of stretch marks, post partum, use 1 ounce Rosehip seed and 1 ounce Tamanu or Evening Primrose oil with 1 milliliter Sage essential oil and 2 milliliters with Rosemary Verbenone essential oil; again apply regularly until the marks are no longer visible.
So these are just a few skin care formulas commonly used in aromatherapy. Many more exist for a great variety of skin conditions - there is much information available on the internet or in bookstores. Remember, when creating your own blends, be conservative with the amounts of essential oils - they do work in small amounts. Also, it's always fun to add to these recipes one or more of your favorite aromatic oils - Jasmine, Ylang Ylang, Rose or other oils can add a lovely complex aroma to the blend; one that you'll enjoy wearing. Be creative, be safe and have fun!
