🌱 Botanical Profile

INCI Name: Centella Asiatica Extract
Family: Apiaceae
Part used: Aerial parts (leaves & stems)
Origin: Asia, Madagascar, tropical regions

Centella is a triterpene-rich medicinal plant, meaning its activity comes from highly bioactive compounds that directly influence skin regeneration.

🧪 Chemical Composition (The Real Magic)

Centella’s power lies in its pentacyclic triterpenes, the gold-standard actives in dermatology:

Key compounds:

Asiaticoside
Madecassoside
Asiatic acid
Madecassic acid

These compounds:

Stimulate fibroblasts (collagen-producing cells)
Accelerate wound healing
Reduce inflammation and oxidative stress (PubMed Central)

Additionally, Centella contains:

Flavonoids (antioxidant protection)
Saponins (skin conditioning)
Phytosterols (barrier repair) (PubMed Central)

✨ Skin Benefits (Evidence-Based)

1. Powerful Skin Repair & Wound Healing

Centella is one of the few botanicals clinically shown to:

Accelerate wound healing
Improve burns, scars, and skin lesions
Support tissue regeneration (PubMed Central)

➡️ Mechanism:

Increases fibroblast activity
Stimulates collagen synthesis
Enhances angiogenesis (new blood vessels)

2. Collagen Boosting & Anti-Ageing

The triterpenes:

Stimulate collagen types I & III
Improve skin firmness and elasticity
Reduce fine lines and photoaging (Cleveland Clinic)

➡️ Result:

Plumper, smoother, more resilient skin

3. Anti-Inflammatory & Soothing (Sensitive Skin Hero)

Centella:

Reduces redness and irritation
Calms reactive, rosacea-prone skin
Supports conditions like eczema & psoriasis (PubMed Central)

➡️ Ideal for:

Compromised barrier
Post-treatment skin (peels, retinol, lasers)

4. Barrier Repair & Hydration

Studies show improvement in:

TEWL (transepidermal water loss)
Skin hydration
Elasticity (ScienceDirect)

➡️ Mechanism:

Strengthens lipid barrier
Enhances moisture retention

5. Antioxidant Protection

Centella protects against:

UV-induced damage
Pollution
Free radical stress

➡️ Helps prevent premature ageing and pigmentation

6. Scar & Stretch Mark Reduction

Widely used in:

Scar gels
Post-surgery recovery
Anti-stretch mark creams

➡️ Improves:

Skin density
Collagen organization
Healing speed

🧴 Forms Used in Cosmetic Formulation

Centella is incredibly versatile and comes in multiple formats:

1. Aqueous Extract (Most Common)

Water or glycerin-based
Rich in madecassoside & asiaticoside
Ideal for serums, toners, creams

✔️ Best for: soothing, hydrating formulas

2. Glycerite (DIY-friendly 🌿)

Gentle extraction method
Suitable for sensitive skin
Mild but effective

✔️ Best for: natural skincare lines

3. Powder Extract (Standardised)

Often standardized (e.g., 10%, 40%, 95% triterpenes)
Requires solubilization

✔️ Best for: advanced formulations

4. Oil Infusion

Less active in triterpenes (they are not oil-soluble)
Contains minor lipophilic compounds

✔️ Best for: balms, oils (supportive, not active)

5. Isolated Actives

Madecassoside
Asiaticoside

✔️ High-performance cosmeceuticals

6. Advanced Delivery Systems (High-end formulation)

Liposomes
Phytosomes
Nanoemulsions

➡️ Enhance penetration and bioavailability (ScienceDirect)

⚗️ Solubility & Formulation Guidelines

Property	Details
Solubility	Water-soluble (primary actives)
Heat sensitivity	Moderate (add <40°C ideally)
pH stability	~5–7 optimal
Phase	Water phase or cool-down

⚠️ Important:

Triterpenes are NOT oil-soluble → oil infusions ≠ active extract
Works beautifully with:
- Niacinamide
- Panthenol
- Hyaluronic acid
- Ceramides

📊 Recommended Usage Percentages

This depends on the form:

Extract (general cosmetic use)

0.5 – 5% typical
Studies often use 2.5 – 5% in emulsions (PubMed Central)

Regulatory / safety data

Cosmetic use reported up to 0.5% (pure extract basis) (SAGE Journals)

Active compounds (isolated)

Madecassoside: 0.05 – 0.2%

DIY glycerite

2 – 10% depending on strength

🧪 Best Product Applications

Centella is incredibly versatile — but it shines in:

💧 Serums
