8 truths to know everything about coconut oil!
Long confined to tropical cuisines, coconut oil is now establishing itself as a key ingredient in skin and hair care products. Its unique richness in saturated fatty acids—particularly lauric acid—gives it moisturizing, protective, and antibacterial properties that are of interest to both dermatologists and formulators. Let's find out why this plant-based raw material deserves a place in your beauty routine.
1. Botanical and technical identification card
Native to equatorial regions, Coconut belongs to the family of Palm family. Coconut oil Cosmetic-grade oil is obtained from the first cold pressing (without solvents) of fresh pulp, a process that preserves vitamins and antioxidants. Solid below 26°C, it melts instantly on contact with the skin.
2. A unique lipid matrix
- Majority saturated fatty acids : lauric, myristic, and palmitic, responsible for the protective film-forming effect.
- Unsaturated fatty acids : oleic which provides skin suppleness and linoleic which maintains elasticity.
- Natural antioxidants : mainly vitamin E (tocopherol), which traps free radicals.
- Comedogenic rating : 4/5, indicating a high risk of pore blockage in oily skin.
3. Hydration: a measurable reduction in water loss
In people with atopic dermatitis, topical applications of virgin coconut oil can reduce trans-epidermal water loss by up to 46% (TP4T).
Result: a reinforced skin barrier and a lasting feeling of comfort for dry or eczema-prone skin.
4. Confirmed anti-inflammatory properties
Coconut oil inhibits pro-inflammatory mediators such as TNF-α, helping to soothe redness and irritation, especially after sun exposure.
5. A discreet but effective antioxidant shield
Its content in tocopherols neutralizes free radicals generated by UV rays, pollution, or tobacco, delaying collagen degradation and the appearance of wrinkles.
6. Comedogenicity: asset or pitfall?
Although antibacterial, the oil forms an occlusive film that can clog pores. Due to its high comedogenic rating, it is not recommended for combination to oily skin, as it may exacerbate acne.
7. Unmatched capillary penetration
Its low molecular weight and lauric acid's strong affinity for keratin allow it to penetrate deep into the fiber, limiting protein loss during washing. Dry or damaged hair gains strength and shine.
8. Scalp microbiome: an ally against dandruff
A study has shown that regular massages with coconut oil rebalance the bacterial and fungal flora of the scalp, reducing flaking and itching.
Instructions for use
- Face : in the form of balm or pure oil
- Body : body milk or body butter
- Hair : 30 mm oil bath before shampooing
- Scalp/dandruff : gentle massage 15 mm before washing
Store the oil away from light at a temperature between 2°C and 15°C to preserve its components.
