Tamanu Oil vs. Cacay Oil: Discover the Best for Your Skincare
- Cacay oil: 70%+ Linoleic Acid, 10-14% Oleic Acid - lightweight, non-comedogenic, ideal for most skin types
- Tamanu Oil: Up to 70% Oleic Acid, 4-9% Linoleic Acid - richer, more occlusive
- Cacay has confirmed natural Vitamin A (retinol precursors) - Tamanu Oil not a significant source of vitamin a
- Cacay's high Vitamin E content gives it a 3+ year shelf life - significantly longer than most oils
- NAYA clinical trial: 10% Cacay Oil improved hydration in 100% of participants in a single application
Tamanu Oil: an overview
Origin: French Polynesia and Indian-Pacific Rim (Calophyllum inophyllum)
Extracted from the dried seeds of the Tamanu tree, which flowers twice a year on Pacific coastal beaches. Produces a distinctive dark green oil. One of the most labour-intensive oils to produce - 20kg of fruit yields 1kg of oil, dried over 8 weeks before cold-pressing. Highly regarded for wound healing, anti-inflammatory and antimicrobial properties. High in oleic acid (70%+).
Head-to-head: Cacay Oil vs Tamanu Oil
| Cacay Oil | Tamanu Oil | |
|---|---|---|
| Linoleic Acid | 70%+ (vs 4-9% in tamanu) | 4-9% |
| Oleic Acid | 10-14% | Up to 70% |
| Vitamin A | Confirmed - natural retinol precursors | Not a significant source of Vitamin A |
| Vitamin E | High tocopherol content - 3+ year shelf life | Moderate - stable due to fatty acid composition |
| Comedogenic rating | 0-1 | 0-2 |
| Best for | Better for daily use, anti-ageing, barrier repair, oily and acne-prone skin, and general skin health | Better for targeted wound healing, scars, anti-inflammatory treatment and dermatological concerns |
Linoleic acid: why the difference matters
Linoleic Acid (Omega 6, Vitamin F) is one of the most important essential fatty acids for skin health. It cannot be synthesised by the body, so topical application is the most reliable way to maintain levels in the skin. Its roles include:
- Strengthening the skin barrier and reducing transepidermal water loss
- Regulating sebum composition - research has linked linoleic acid deficiency to excess sebum production and blocked pores
- Reducing inflammatory response in reactive skin
- Supporting cell membrane integrity throughout the dermis
Cacay oil contains over 70% Linoleic Acid - roughly 17 times the concentration found in Tamanu Oil. This is the single most significant difference between the two oils in practical terms.
Oleic Acid (Omega 9), by contrast, is better suited to drier skin types where occlusive nourishment is the primary need. Tamanu Oil is higher in oleic acid at Up to 70%, making it particularly rich and emollient. For very dry or mature skin this is a genuine benefit. For oily, combination or acne-prone skin, a high oleic acid oil can contribute to pore congestion.
Independent 21-subject clinical trial (2018): 10% Cacay Oil improved skin surface hydration in 100% of participants in one application with gradual increase throughout the day without reapplication.
Vitamin A: the anti-ageing factor
Cacay oil's confirmed natural Vitamin A content is one of its most significant differentiators. The natural retinol precursors in cacay undergo a two-step conversion in the skin - retinol to retinaldehyde, then to retinoic acid - making them gentler than synthetic retinoids while still delivering collagen-stimulating and cell-renewal benefits.
NAYA verifies the Vitamin A content of every batch of cacay oil through independent lab testing in Germany and Colombia. This is not a standard practice across the industry, and the presence of natural retinol precursors in cacay oil is confirmed rather than assumed.
Not a significant source of Vitamin A
"Cacay oil contains natural retinol precursors verified in every batch through independent lab studies. The result is gentle but effective anti-ageing action that is suitable even for sensitive skin."
Which oil is right for you?
Choose cacay oil if: you have oily, combination, acne-prone, reactive or barrier-weakened skin, or if anti-ageing, Vitamin A activity and long-term skin health are your priorities. Cacay's lightweight profile makes it suitable for year-round daily use on most skin types.
Choose tamanu oil if: better for targeted wound healing, scars, anti-inflammatory treatment and dermatological concerns.
Both oils can also work together - cacay as your daily lightweight oil layer, tamanu oil used occasionally or on specific areas that need deeper nourishment.

What is the main difference between cacay oil and tamanu oil?
Their fatty acid profiles. Cacay oil is 70%+ Linoleic Acid - lightweight, non-comedogenic and ideal for most skin types. Tamanu Oil is higher in oleic acid, making it richer and more occlusive. Cacay also has confirmed natural Vitamin A and a significantly longer shelf life due to its high Vitamin E content.
Is tamanu oil or cacay oil better for acne?
Cacay oil is better for acne-prone skin as a daily facial oil - its 70%+ Linoleic Acid is directly suited to the sebum imbalance that drives breakouts. Tamanu oil has useful anti-inflammatory properties for active blemishes but its high oleic acid content makes it less suited for oily or acne-prone skin as a daily oil.
Does cacay oil have more Vitamin A than tamanu oil?
Yes. Cacay oil's Vitamin A content has been confirmed through independent lab testing in Germany and Colombia. Not a significant source of Vitamin A
Which oil has a longer shelf life?
Cacay oil. Its high Vitamin E content makes it unusually stable with a shelf life of 3+ years. Tamanu Oil varies - Moderate - stable due to fatty acid composition.
Can I use both cacay oil and tamanu oil together?
Yes. They have complementary profiles. Cacay works well as your daily lightweight oil layer providing Linoleic Acid, Vitamin A and antioxidant protection. Tamanu Oil can be used occasionally or on specific dry areas needing deeper nourishment.
