@donasmrs-- That's probably the case. The ingredients you mentioned are all very good and beneficial for scar healing.
I personally heal my scars with vitamin E oil. I'm afraid to try essential oils because I have very sensitive skin. I know I'm allergic to tea tree oil and lavender oil is also irritating. Oils like vitamin E oil and olive oil never irritate however. I'm also fond of beeswax. I've noticed that the more moisturized the skin, the faster scars heal. So it's important to use a herbal treatment that is very moisturizing for skin and also gentle.
