Healing old scars:
If a scar is pinkish and still healing, you can reduce the appearance. If they're white and healed, you're pretty much stuck with them.
15mL creme base
2 drops either eucalyptus, orange, basil, clary-sage, petitgrain
3 drops either cypress, lavender, lemongrass, geranium
2 drops either neroli, frankincense, benzoin, immortelle, jasmine, vetiver
Add oils to a couple mL's of glycerin, stir well, then add to creme, stir well. You can add the essential oils to one of these carrier oils to make a massage oil or compress:
15mL either avocado oil, rosehip seed oil, or vitamin E oil - You can even add a few mLs of these carrier oils to the creme recipe.
You can also make a toner by mixing the oils in with the glycerin and add to 250mL of distilled water.
2 drops either cajeput, bergamot, lemon, clary-sage
3 drops either cypress, sandwood
2 drops either ginger, frankincense, rose
Follow same steps, for creme or oil recipe. Your carrier oil choices for varicose veins would be either almond, calendula, or St. Johns Wort. If you're adding a carrier oil to the creme, only use calendula or St. Johns Wort.
You can always substitute lavender for an essential oil that's called for in a recipe that you can't get your hands on.
Hope this helps!
