Frankincense has been a prized resin for thousands of years, known as the “king of essential oils” for its incredible versatility. But when you start exploring, you quickly realize not all frankincense is the same. Two of the most popular species you’ll encounter are Boswellia carterii and Boswellia serrata. When choosing between Boswellia carterii vs Boswellia serrata, the best choice depends on your specific needs: Boswellia carterii is often superior for skin rejuvenation and creating an uplifting atmosphere, while Boswellia serrata is the preferred choice for powerfully calming inflammation and soothing irritated skin.
While they share many core benefits, these two varieties come from different trees, different parts of the world, and have unique properties. Let’s break down the essential differences to help you make an informed choice.
Geographic Origin: Where They Come From Matters
The story of each frankincense oil begins with its home. The specific soil, climate, and environment where the Boswellia tree grows has a huge impact on the final resin it produces.
- Boswellia carterii: This species is primarily sourced from the arid, rocky landscapes of East Africa and the Arabian Peninsula, with Somalia being a major producer. It thrives in harsh conditions, which concentrates the aromatic compounds in its resin.
- Boswellia serrata: Often called Indian Frankincense, this variety is native to the mountainous regions of India. It has a deep history in Ayurvedic medicine, the traditional wellness system of India, where it’s known as “salai guggul”.
This geographical distinction is the first clue to their different chemical makeups and aromas. When you see a brand specify the country of origin, it’s a mark of quality and transparency. For instance, knowing that an oil is Boswellia serrata from India—like Alize Living’s Organic Frankincense (Boswellia serrata)—gives you clear insight into its expected profile, a practice that trusted brands follow.
Resin and Harvesting Practice
Both oils originate from a precious, gummy sap. Harvesters make careful incisions in the bark of the Boswellia tree, which then “bleeds” a milky white resin. This sap hardens into “tears” upon contact with the air. These resin tears are then collected and steam distilled to produce the essential oil.
This ancient process is labor intensive and requires great skill. Harvesters must know exactly how and when to tap the trees without harming them, often letting them rest for a season to recover. This careful, sustainable practice is crucial, as over harvesting can endanger the trees.
While the general method is the same, the resins themselves can differ:
- Carterii resin is often softer and more pliable.
- Serrata resin tends to be harder and more brittle.
It’s also vital to distinguish between the resin and the essential oil. The raw resin contains heavy molecules called boswellic acids, but these compounds are largely absent in steam distilled essential oil.
Yield and Cost Difference
Producing a small bottle of pure frankincense essential oil requires a significant amount of resin. The yield, or the amount of oil that can be extracted from the resin, is quite low for both species.
- Boswellia carterii typically has a lower oil yield, sometimes around 5 to 6 percent. The labor intensive harvesting combined with this lower yield often makes it slightly more expensive.
- Boswellia serrata often produces a higher yield of oil, sometimes around 10 percent, which can make it a more cost effective option.
Because authentic frankincense oil is a premium product, be wary of unusually cheap options. Low prices can be a red flag for adulteration or synthetic fillers. Investing in a high quality, 100% pure oil from a reputable source ensures you get the true benefits without unwanted additives.
Chemical Composition: The Science Behind the Scent and Benefits
Here is where the Boswellia carterii vs Boswellia serrata comparison gets really interesting. Their different chemical profiles explain why they excel in different areas.
-
Boswellia carterii is rich in compounds called monoterpenes, particularly alpha-pinene and limonene. These smaller molecules contribute to its uplifting aroma and are excellent for skin rejuvenation and respiratory support. It also contains incensole acetate, which has been studied for its calming effects on the mind.
-
Boswellia serrata is known for its high concentration of alpha-thujene and contains compounds that support its powerful anti inflammatory reputation in Ayurvedic medicine. While the essential oil doesn’t contain significant boswellic acids, its unique profile makes it a standout for soothing irritated skin and calming inflammation. Its main active compounds are known for their potent anti inflammatory and pain relieving properties.
Essentially, think of Carterii as a master of rejuvenation and emotional balance, while Serrata is a specialist in soothing and calming.
Aroma Profile: What Do They Smell Like?
While both are distinctly “frankincense,” their scents have subtle but important differences.
-
Boswellia carterii offers what many consider the classic frankincense aroma: warm, balsamic, rich, and slightly citrusy. It’s the deep, resonant scent often associated with spiritual practices and meditation, sometimes described as the “church scent”.
-
Boswellia serrata has a different bouquet. Its aroma is often described as deeper, earthier, and slightly spicier or more herbal. This makes it a grounding and centering scent, perfect for creating a focused environment; if you enjoy these notes, explore our Woody Essential Oils collection.
The choice here is purely personal. If you prefer a bright, classic scent, you might lean towards Carterii. If you enjoy a spicier, more earthy aroma, Serrata could be your perfect match.
Viscosity, Texture, and Absorption
How an oil feels and absorbs into the skin is crucial for topical use. Frankincense in general is known for being a lightweight and fast absorbing oil.
-
Boswellia carterii essential oil is often slightly thicker or more viscous. It can feel richer on the skin, making it a great choice for dry or mature skin types that need lasting moisture.
-
Boswellia serrata oil tends to be lighter and less viscous. This thin consistency allows it to absorb very quickly without leaving a heavy feeling, making it ideal for oily or combination skin.
A fascinating fact about frankincense is that its compounds may enhance the absorption of other ingredients in a skincare formula, making it a great “booster” for your favorite serums and creams.
Hydration Level and Skin Type Suitability
Frankincense is widely considered gentle and suitable for most skin types, but one may be a better fit for your specific needs.
-
Boswellia carterii, with its richer texture, provides deeper moisture and is an excellent fit for dry or mature skin. It helps to soothe and hydrate without clogging pores.
-
Boswellia serrata is the stronger choice for managing irritation. Its lighter texture and anti inflammatory power make it a fantastic option for oily, combination, and acne prone skin types.
Frankincense is generally very well tolerated, even by sensitive skin. Its calming properties can actually help reduce redness and reactivity over time.
Acne and Inflammation Management
For those struggling with breakouts and redness, the choice between Boswellia carterii vs Boswellia serrata becomes clearer.
-
Boswellia carterii has antibacterial and anti inflammatory properties that can certainly help with acne. It’s a good all around choice for general skin calming.
-
Boswellia serrata is particularly effective for managing acne related inflammation. Its high concentration of specific anti inflammatory compounds makes it a powerful ally for reducing the swelling and redness associated with breakouts. If your primary concern is calming angry, irritated blemishes, Serrata is the stronger choice.
Anti-Aging and Collagen Support
Both species are stars in anti aging skincare, helping to firm the skin, reduce the appearance of wrinkles, and promote a youthful glow.
-
Boswellia carterii is often preferred for skin regeneration and anti aging routines. Its rich monoterpene profile helps soothe the skin and improve tone and elasticity.
-
Boswellia serrata also contributes to anti aging by powerfully reducing inflammation, which is a key driver of skin aging. By calming the skin, it helps protect existing collagen and maintain a smooth, even complexion.
Blending Recommendations
Frankincense is a versatile team player and blends beautifully with a wide range of other essential oils.
- For Skin: Both Carterii and Serrata pair wonderfully with oils like Lavender, Geranium, and Rose in a facial serum. For a potent anti aging blend, try a few drops in a carrier oil like jojoba or rosehip seed.
- For Mood: To enhance the calming, meditative properties, blend either frankincense with Sandalwood, Bergamot, or Cedarwood. Carterii’s bright notes go well with citrus oils like Sweet Orange, while Serrata’s earthy aroma is lovely with spicy oils like Clove or Ginger.
- For Diffusion: A simple blend of 3 drops of lavender, 2 drops of sweet orange, and 1 drop of frankincense creates a peaceful and uplifting atmosphere in any room.
When creating your own blends, it’s essential to start with high quality, pure ingredients. Exploring a curated collection in the Alize Living shop can give you confidence in the purity and potency of your creations.
