What makes tamanu oil unique is calophyllolide. This compound is found in no other plant oil. It stimulates the formation of new skin tissue and has proven wound-healing properties.
Note: In Polynesian medicine, tamanu oil has been called “green gold” for centuries. It has been used for burns, cuts, and skin infections. It is one of the few oils with clinically supported wound-healing properties.
Skin: when to use which?
Eczema (active flare-ups)
For active eczema with redness and itching, kukui oil is more effective. Its high alpha-linolenic acid content actively reduces inflammation from within.
Winner: kukui oil for active inflammation.
Eczema (recovery phase)
When the flare-up fades and the skin needs to heal, tamanu oil comes into play. Calophyllolide stimulates the formation of new skin tissue and speeds up the recovery process.
Winner: tamanu oil for recovery.
Scars
Tamanu oil is one of the best-studied plant oils for scar treatment. The combination of calophyllolide and delta-tocotrienol stimulates cell renewal.
Winner: tamanu oil.
Daily use on the full face
Kukui oil is lighter, nearly odorless, and more comfortable for daily use. Tamanu oil has a strong scent and a dark green color that not everyone enjoys.
Winner: kukui oil.
Tip: Combine both oils. Use kukui oil as your daily face oil and apply tamanu oil as a spot treatment on specific problem areas, scars, or eczema patches.
