Persistent redness, dryness, loss of elasticity... These signs may indicate a subtle but formidable phenomenon:’inflammaging.This term refers to low-grade chronic inflammation that accelerates skin aging. Even with a rigorous skincare routine, internal and environmental factors can trigger this process.

🔬 What is inflammaging?

Inflammaging is a chronic, silent, and persistent inflammation that affects the skin as we age. It results from the continuous activation of the immune system, even in the absence of external aggression. This phenomenon leads to the degradation of collagen and elastin, weakening the skin's structure and accelerating the appearance of signs of aging.

🧪 Effects on the skin

• Collagen loss : From the late twenties onwards, collagen production naturally decreases. Inflammaging accentuates this loss, leading to wrinkles and sagging skin.
• Weakening of the skin barrier : the skin becomes more permeable, promoting dehydration and the penetration of irritants.
• Accumulation of senescent cells : these aging cells release pro-inflammatory substances, perpetuating a vicious cycle of inflammation.

⚠️ Trigger factors

• Allergens: Allergens can cause chronic inflammation in people with mature skin because their skin barriers are more permeable.
• Chronic stress : Prolonged stress stimulates the production of inflammatory cytokines, disrupting the skin's balance.
• UV exposure : Ultraviolet rays damage the DNA of skin cells, triggering an inflammatory response.
• Unbalanced diet : excessive consumption of sugars and saturated fats promotes systemic inflammation.
• Pollution Fine particles and other environmental pollutants induce oxidative stress, contributing to inflammaging.

🔍 Clinical signs

• Diffuse redness : particularly on the T-zone (forehead, nose, chin).
• Dry, rough skin : despite regular hydration.
• Early wrinkles : appearance of fine lines before the usual age.
• Dull complexion : loss of the skin's natural radiance.
• Increased sensitivity : heightened reactions to cosmetics or climate variations.

🛡️ Prevention and strategies

1. Daily sun protection

Use a broad-spectrum sunscreen (SPF 50 minimum) to prevent UV damage.

2. Anti-inflammatory diet

Choose foods rich in antioxidants (red fruits, green vegetables, nuts) and limit refined sugars.

3. Stress management

Practice relaxation techniques (meditation, yoga) to reduce the production of cortisol, a pro-inflammatory hormone.

4. Appropriate topical treatments

Incorporate products containing soothing and repairing ingredients.

A. Fragrance allergens

Certain odor compounds, whether natural or synthetic, are known for their allergenic potential.
Examples : Limonene, Linalool, Geraniol, Citral

B. Denatured alcohols

Drying alcohols can cause skin irritation and dehydration.
To be avoided : Alcohol Denat., (Ethanol* in small quantities)

C. Essential oils

Although they are natural, essential oils are powerful concentrates that contain sensitizing molecules.

d. Old chemical sunscreens

Some chemical UV filters are now controversial due to their potential to cause irritation:
Examples Octinoxate, Oxybenzone,

5. Regular physical activity

Moderate exercise stimulates blood circulation and reduces systemic inflammation.
