Editing How to Apply Essential Oils (section)

=== Topical Use (Skin Application) ===
Applying essential oils '''topically''' to the skin is another primary route of use, including methods like massage, bathing, compresses, and spot application. Due to their high concentration and potency, pure essential oils usually '''should not be applied directly''' to large areas of skin (Essential oil - Wikipedia). For topical use, essential oils must first be '''diluted''' in a suitable ratio with a base oil (also known as a carrier oil) to reduce irritation and promote absorption (Essential oil - Wikipedia). Common carrier oils include sweet almond oil, grapeseed oil, and jojoba oil, which are non-irritating and moisturizing, helping the essential oil penetrate the skin. When blending, typically add 1-3 drops of essential oil to 5 ml of carrier oil (about 1%-3% concentration) for use on the face or other delicate skin; body massage can use a higher concentration, but generally not exceeding 5%. '''Massage''' is one of the most common topical methods, using massage movements to enhance oil penetration and boost local blood circulation. For instance, massaging sore muscles with diluted rosemary or ginger essential oil can help relieve tension and pain. '''Bathing''' is also popular: add essential oils to warm bathwater (usually 5-10 drops, mixed first with bath salts or milk to disperse), allowing absorption through both skin and respiration for relaxation and skin care. Additionally, blended essential oil massage oils can be used for '''spot application/compresses''', such as dabbing a diluted peppermint oil blend on the temples to relieve headaches, or applying a gel containing tea tree oil to pimples for anti-inflammatory and antibacterial effects. Because essential oil molecules are very small and lipid-soluble, they can quickly penetrate the skin and enter the bloodstream and lymphatic system. Topically absorbed essential oils are metabolized and completely eliminated from the body without long-term residue.
