Natural oils work in perfect harmony with the skin and hair because their biological composition closely resembles human sebum. This natural affinity allows them to penetrate deeply, repair the protective barrier and deliver visible benefits from the very first use.

In this article, we break down in clear, simple scientific terms:

• why natural oils are so effective

• what they truly contain

• and why blending different oils creates even more powerful results

---

The Main Reason: Biological Compatibility with Human Sebum

The molecular structure of natural oils is remarkably similar to the lipids that make up human sebum.
Because of this similarity:

• The skin recognizes and absorbs them easily

• They integrate without causing irritation

• They repair the hydrolipidic barrier

• They prevent moisture loss

• They nourish without clogging pores

This biological compatibility is the fundamental reason why natural oils often perform better than many synthetic formulations.

What Do Natural Oils Really Contain? (Cold-pressed or Macerated Oils)

Fatty Acids

They make up more than 95% of an oil’s composition.
The most important ones include:

• Oleic

• Linoleic

• Linolenic

• Palmitic

• Stearic

These lipids are essential because they also form part of the skin’s natural protective barrier.
Their functions include:
✔ Strengthening the skin barrier
✔ Preventing moisture loss
✔ Softening without clogging pores

---

Phytosterols

Plant compounds similar to human cholesterol.
They help:
✔ Repair the skin barrier
✔ Reduce inflammation
✔ Improve elasticity

---

Squalene

A natural component found in human sebum and in oils such as olive and argan.
It provides:
✔ Antioxidant protection
✔ A soft, silky texture
✔ Greater flexibility in skin and hair

---

Fat-Soluble Vitamins

Natural oils contain vitamins A, D, E and K.
Vitamin E stands out because:
✔ It is a powerful antioxidant
✔ It protects oils from oxidation
✔ It maintains skin elasticity

---

Phenolic and Terpenic Compounds

Especially present in essential oils and macerated oils.
Their functions include:
✔ Improving microcirculation
✔ Fighting microorganisms
✔ Stimulating cell renewal

---

How Do Natural Oils Work on the Skin and Hair?

Biological Compatibility

Because their structure resembles human sebum, natural oils prevent irritation and allow deeper, more natural absorption.

---

Protective Barrier Effect

They form a semi-permeable film that:
✔ Locks in moisture
✔ Shields the skin from external aggressors
✔ Maintains the natural water–oil balance

---

Antioxidant Action

Natural oils neutralize free radicals, helping reduce signs of aging in both skin and hair.

---

Are Oil Blends Useful? Yes — Because of Their Differences

The main benefit of mixing oils does not come from their similarities but from their differences.

Each oil has a unique profile of:

• fatty acids

• vitamins

• antioxidants

• secondary compounds

• viscosity

• absorption speed

When combined, these differences create a more balanced, more effective composition with properties that no single oil can offer on its own.

---

Scientific Benefits of Blending Oils

Balanced Fatty Acid Profile

Each oil provides its own dominant fatty acid:

• Castor → ricinoleic

• Jojoba → eicosenoic

• Olive → oleic

• Grape or rosehip → linoleic

A balanced blend:
✔ Deeply hydrates
✔ Regulates sebum
✔ Improves skin repair
✔ Absorbs more effectively

---

Synergy Between Compounds

When fatty acids, antioxidants, vitamins and phytosterols come together:
✔ They enhance each other’s benefits
✔ Stability increases
✔ Absorption improves
✔ Biological efficacy multiplies

---

Ideal Texture

Blending thick oils with lighter ones creates:
✔ A smoother application
✔ A balanced absorption rate
✔ A pleasant, comfortable skin feel

---

Greater Stability

Vitamin-E-rich oils protect more delicate oils from oxidation, increasing the product’s lifespan.

---

Multiple Functions in a Single Product

A well-designed blend can:
✔ Hydrate
✔ Regenerate
✔ Protect
✔ Reduce inflammation
✔ Add shine and softness
✔ Support hair growth

---

Better Absorption

Each fatty acid contributes something unique:

• Oleic → increases permeability

• Linoleic → reduces inflammation

• Palmitic → reinforces the barrier

Together they:
✔ Improve distribution
✔ Reduce irritation
✔ Enhance overall results

Blending natural oils is not just useful — it is scientifically superior.
Balanced blends provide more effectiveness, better stability, improved absorption and a set of benefits that no single oil can deliver on its own.
