Macadamia oil
Description
Macadamia Oil (Macadamia integrifolia) is a restructuring, nourishing, and softening emollient that penetrates the upper layers of the epidermis and envelops the skin in a film that reduces transepidermal water loss. It is a great ally for regenerating devitalized, aging skin, or skin affected by stretch marks and scars, while also acting as an excellent protective shield against environmental factors.
It is recommended in the formulation of products intended for dry, mature, or barrier-compromised skin, as well as in the care of dry or damaged hair, where it works to improve flexibility and lubricate the hair fiber.

Usage & Synergies
Face care
Macadamia Oil is a good choice for mature, dry skin, including skin prone to redness or reactivity. Its biomimetic profile makes it suitable for the daytime routine as well, not just at night. Due to its medium absorption rate, it ensures an optimal glide on the skin, making it suitable for cosmetic massage procedures.
Practical recommendations
- Daily face oil: Apply 2-3 drops to clean skin in the morning or evening.
- Ingredient in anti-aging creams and serums: Incorporate into formulas for mature, dry skin with a damaged barrier.
- Lightweight makeup remover: Apply a few drops to the face, massage, and wipe off with a damp cloth.
Synergies in face care
For a regenerating serum with a biomimetic profile, the synergy with Marula Oil and Coenzyme Q10 offers an anti-aging effect and maintains the tone of mature skin. As a light day serum, the association with Organic Evening Primrose Oil and Rosehip CO2 Extract completes the nutritional spectrum without weighing down the texture. On sensitive skin prone to redness, combining it with Bisabolol and Olive-Silicone maintains a sensation of comfort.
Body care
At the body level, Macadamia oil excels in massage oils for mature skin, anti-stretch mark formulas, and sun care or after-sun products. Due to its medium absorption rate, it ensures an optimal glide on the skin, making it well-suited for cosmetic body massage procedures as well.
Practical recommendations
- Massage oil: Use pure or blended with other vegetable and essential oils. It leaves the skin feeling silky-smooth.
- Ingredient in anti-stretch mark formulas: Incorporate at 20-30% into preventive and curative oils or creams.
- Lip balm: It can be a staple base ingredient in balms, thanks to its fine texture and high tolerability.
Synergies in body care
As a massage oil for mature skin, the synergy with Grape Seed Oil and Geranium Essential Oil provides nourishment and a pleasant sensory profile. In an anti-stretch mark formula, the association with Centella Asiatica Oil and Wheat Germ Oil completes the regenerating action.
Hair care
On hair, Macadamia oil is recommended for dry, damaged hair or hair with split ends, where the palmitoleic acid in its composition helps smooth the cuticle and add shine.
Practical recommendations
- Leave-in ends serum: Apply a few drops to dry or damp ends for smoothing and shine.
- Pre-shampoo on lengths: Apply to dry lengths, leave on for 20-30 minutes, then shampoo. It protects the strands from dehydration.
- Ingredient in hair masks: Incorporate into nourishing masks for damaged hair, alongside specific actives.
Synergies in hair care
As a nourishing serum for color-treated hair, the synergy with Karanja Oil and Phyto-Silicone provides nourishment, protection, and shine. For damaged hair, the association with Organic Babassu Oil or Ricin Oil and Ceramides completes the structuring of the fiber.
Frequently Asked Questions (FAQ)
What is palmitoleic acid and why is it special?
Palmitoleic acid (Omega-7) is a monounsaturated fatty acid naturally present in youthful sebum, the sebaceous gland produces it in young people, but production declines significantly with age. Its topical replacement through oils rich in palmitoleic acid, such as Macadamia, helps restore the lipid profile of mature sebum, explaining this oil's remarkable affinity with aging skin.
Is it comedogenic?
It has a comedogenicity index of 2 (out of 5), which is considered acceptable for most applications. It is not recommended as the primary oil for actively acne-prone skin, but on normal or mature skin with moderate oily tendencies, it can be well tolerated in moderate doses.
Can it be used on baby skin as well?
Yes, its tolerability is excellent and there are no contraindications for its use on the delicate skin of young children.
