Frankincense essential oil (EO) is derived from the resin of the Boswellia tree. This highly concentrated plant extract captures a powerful profile of therapeutic compounds and is known for its rich, woodsy, and slightly sweet aroma. To use this potent substance safely on the skin, it must be combined with a vegetable oil known as a carrier oil, which acts as a base to facilitate topical application.
Why Dilution Is Required
Essential oils are extremely concentrated, often 50 to 100 times more potent than the botanical material they were extracted from. Applying frankincense EO directly to the skin, known as using it “neat,” can overwhelm the skin and cause adverse reactions, including irritation, redness, or contact sensitization. Dilution with a carrier oil reduces the concentration to a safe level, maximizing the oil’s effectiveness.
Carrier oils contain fatty acids that are less volatile than essential oil compounds. This helps the frankincense linger on the skin longer for better absorption instead of evaporating quickly. Blending the frankincense into a vegetable oil base also creates a smooth texture, allowing for easy and even spreadability across the body.
How to Match Carrier Oil to Skin Needs
Choosing a carrier oil depends on your skin type and the desired application. Primary considerations include the oil’s absorption rate, its potential to clog pores (comedogenic rating), and its inherent aroma. Oils are categorized by viscosity, ranging from lightweight “dry” oils that absorb rapidly to richer, emollient oils that leave a moisturizing barrier.
Individuals with oily or acne-prone skin should select oils with a low comedogenic rating to avoid blocking pores. Conversely, dry or mature skin benefits from richer oils containing higher levels of oleic acid, which provides deep moisture and supports the skin barrier. While many carrier oils are nearly odorless, some, like unrefined sesame or olive oil, possess a distinct scent that could interfere with the frankincense aroma. Stability and shelf life should also be considered, as some oils are prone to quicker rancidity.
Best Carrier Oil Options for Frankincense
Frankincense has a warm and complex scent profile, pairing well with oils that have a neutral or slightly sweet, light aroma. The following options offer excellent synergy based on texture and skin benefits.
Jojoba Oil
Jojoba oil is frequently considered an excellent match because it is a liquid wax that closely mimics the skin’s natural sebum. This unique composition makes it balancing for all skin types, including oily or acne-prone skin, as it helps regulate oil production without clogging pores. Its light, non-greasy texture and faint, nutty scent allow the frankincense aroma to remain prominent, making it a perfect base for a daily facial serum.
Fractionated Coconut Oil (FCO)
Fractionated Coconut Oil (FCO) is highly recommended due to its lightweight nature and stability. FCO is produced by removing the long-chain triglycerides from standard coconut oil, leaving only the liquid medium-chain triglycerides. This process ensures the oil remains liquid at room temperature, is virtually odorless, and spreads easily. FCO is an ideal choice for general body massage or a quick-absorbing, all-purpose topical blend.
Sweet Almond Oil
Sweet Almond oil provides a slightly richer, yet still relatively light, texture that is soothing for sensitive and dry skin types. It is rich in Vitamin E and oleic acid, which helps to nourish and soften the skin. This makes it a favored choice for massage and blends aimed at improving skin elasticity. While it has a moderate absorption rate, it leaves the skin feeling supple without excessive residue.
Grapeseed Oil
Grapeseed oil is a fast-absorbing, very light carrier oil that is nearly scentless. This makes it ideal for individuals with very oily or sensitive skin who prefer a non-existent feel. It contains a high percentage of linoleic acid, an omega-6 fatty acid beneficial for acne-prone skin, as it helps balance the skin’s lipid profile. Because it is so thin and rapidly absorbed, grapeseed oil is a good choice for application during warmer weather.
Safe Dilution and Application Guidelines
Once the carrier oil is selected, proper dilution ensures safety and effectiveness. The standard dilution rate depends on the user’s age and the application area.
For sensitive skin, children, the elderly, or facial applications, a dilution of 0.5% to 1% is recommended. This is approximately 3 to 6 drops of essential oil per one ounce of carrier oil. For general topical use on healthy adult skin, a 2% to 3% dilution rate is considered safe, translating to 12 to 18 drops per one ounce (30 milliliters) of carrier oil.
Before applying any new blend extensively, perform a patch test. Apply a small amount of the diluted mixture to a discreet area, such as the inner forearm, and wait 24 hours to monitor for irritation. The finished blend should be stored in a dark glass bottle, away from heat and direct sunlight, to maintain the integrity and stability of the oils.
