Collagen is often referred to as the "protein of youth". Present in the skin, cartilage, ligaments, tendons, and even vascular walls, it plays a fundamental role in the structure and resilience of our tissues. However, from the age of 25-30, its natural production gradually declines, accelerating the visible signs of aging, as well as certain joint or circulatory weaknesses.

There are at least 28 types of collagen identified to date, but types I, II, and III represent more than 90% of the total collagen in the body. These are also the ones most often targeted by dietary supplements and cosmetics:

• Type I: the most abundant, structuring the skin, tendons, and bones.
• Type II: specific to articular cartilage.
• Type III: associated with the elasticity of flexible connective tissues (young skin, blood vessels, lungs).

But this production can only occur efficiently if certain enzymatic cofactors are present. In particular, vitamin C is essential for the hydroxylation of proline and lysine, two amino acids necessary for the correct formation of the collagen triple helix. Without it, even if the fibroblasts are activated, the fibers produced will be unstable or degraded.

The degradation of collagen is mainly linked to:

• the action of the enzymes MMP-1, MMP-2 and MMP-9,
• to oxidative stress (free radicals),
• to glycation, a phenomenon accelerated by a diet rich in fast sugars.

Three natural levers to act on collagen

Numerous plant compounds promote collagen production through the activation of TGF-β1, fibroblast proliferation, or the supply of metabolic cofactors. Among them are:

• Asiaticoside (Centella asiatica)
• Ginsenosides (Panax ginseng)
• Italidiones (Helichrysum italicum)
• Linalool (Lavender, Ho Wood)
• Vitamin C (Rosehip, Sea Buckthorn, Acerola)

2 - Protect Existing Collagen

• Geraniol (Rose Geranium, Palmarosa) inhibits MMP-1
• Rutin and chlorogenic acid (Aronia melanocarpa, green tea)
• Anethole (anise, dose-dependent)

3 - Reduce Inflammation and Oxidative Stress

Chronic inflammation indirectly activates degradation enzymes. The presence of antioxidants and anti-inflammatories in the tissue environment promotes collagen stability.

• α-pinene (frankincense, cistus, pine)
• Limonene (citrus)
• β-caryophyllene (copaiba, black pepper)
• Polyphenols (pomegranate, green tea, turmeric)

Lipid Matrix

For the plant-based matrix, we offer 4 variants:

Synergy 1 - "Complete Action" (3 oils)
Jojoba 50%
Black Seed 30%
Apricot Kernel 20%
This synergy combines the direct action of black seed on collagen, the perfect penetration of jojoba, and the regenerating softness of apricot kernel. Fluid texture, discreet scent, maximum effectiveness: it's the perfect balance between performance and daily use comfort.

Synergy 2 - "Pure Softness" (2 oils)
Jojoba 70%
Apricot Kernel 30%
Ideal for sensitive skin or those who prefer a minimalist approach. This combination offers an exceptional silky texture and a very neutral scent, while providing vitamins A and E to support skin regeneration.

Synergy 3 - "Maximum Protection" (3 oils)
Jojoba 40%
Sesame 35%
Black Seed 25%
For those seeking enhanced antioxidant protection. Sesame provides its specific antioxidants (sesamolin, sesamin) which perfectly complement the action of black seed on collagen. Recommended for mature skin or skin exposed to environmental aggressions.

Synergy 4 - "Antioxidant Simplicity" (2 oils)
Jojoba 60%
Sesame 40%
The simplest but very effective synergy, focusing on the synergy between the regulation of jojoba and the antioxidant power of sesame. Perfect for a preventive anti-aging routine or as a complement to other active treatments.

Instructions for use: Apply 3-4 drops in the evening on clean, damp skin. Massage well in upward movements.

Precautions: Do not use in case of pregnancy and breastfeeding or in children. Prior skin test recommended.

To Conclude

Phytotherapy and aromatherapy offer valuable tools to promote collagen production, protect its structures, and preserve the youthfulness of tissues. Far from miracle promises, it is through regular, reasoned, and well-documented use that these approaches reveal their full effectiveness.

In light of current data, a synergy between plant extracts, essential oils, and overall lifestyle constitutes one of the most promising natural means to support connective tissue throughout life.
