INCI List 📜
This section helps you correctly identify EGCG on ingredient labels and avoid confusion with broader green tea–derived ingredients that may sound similar but behave very differently on skin.
- Epigallocatechin Gallate – the isolated, standardized, high-potency form of EGCG. This guarantees targeted antioxidant delivery and predictable performance in skincare formulations.
- Camellia Sinensis Leaf Extract – a whole-plant extract that may contain EGCG, but in variable amounts. Antioxidant strength depends heavily on extraction method, standardization, and freshness.
- Camellia Sinensis Leaf – a raw botanical listing that indicates presence of green tea material, but offers no assurance of EGCG concentration or bioavailability.
Formulator note: If a product claims EGCG benefits but does not list Epigallocatechin Gallate explicitly, antioxidant performance may be broader, weaker, or less consistent.
Solubility 💧
EGCG is a water-soluble polyphenol, which influences how it is formulated, stabilized, and layered in routines.
- Fully soluble in water and aqueous systems
- Incompatible with pure oil-based formulations
- Highly sensitive to oxygen, light, and heat exposure
Because of this solubility profile, EGCG performs best in lightweight serums, essences, and emulsions rather than oils or balms.
Maximum Safe Use Concentration (MSUC) 🧪
EGCG is extremely active, meaning more is not always better. Proper dosing is essential for both efficacy and comfort.
| Skin Type / Condition | Recommended Range | Formulation Notes |
|---|---|---|
| Normal / Oily | 0.1–1% | Well tolerated when buffered with soothing agents |
| Sensitive / Reactive | 0.05–0.3% | Use with calming bases; patch testing advised |
| Post-procedure / Compromised | ≤0.1% | Only in barrier-supportive, minimal formulas |
Stability & Storage 🧊
EGCG’s power comes with fragility. Without correct handling, it can oxidize quickly and lose effectiveness.
- Degrades when exposed to UV and visible light
- Oxidizes rapidly in air-permeable packaging
- Heat accelerates color change and potency loss
For maximum benefit, EGCG products should be stored in opaque, airless containers and kept away from direct sunlight.
pH Influence ⚗️
pH plays a critical role in EGCG stability, skin comfort, and longevity.
| pH Range | Stability Level | Skin Experience |
|---|---|---|
| 4.5–6.0 | Optimal | Calm, balanced, low irritation risk |
| 6.1–6.5 | Moderate | Slightly reduced activity |
| >6.5 | Poor | Higher oxidation and irritation risk |
Safety Profile 🛡️
When correctly formulated, EGCG has an excellent safety record in topical skincare.
- Non-photosensitizing and suitable for daytime use
- Does not increase sun sensitivity
- Low sensitization risk at appropriate concentrations
Layering Warnings ⚠️
Because EGCG is biologically active, careless layering can overwhelm reactive skin.
- Avoid stacking with multiple low-pH exfoliating acids
- Do not combine with unstable L-ascorbic acid in the same step
- Space away from aggressive acne treatments if skin is sensitized
The Science of Bioavailability 🔬
EGCG’s relatively small molecular size allows for efficient skin interaction when properly solubilized. Buffering systems and encapsulation further enhance penetration while reducing irritation risk.
Lipid Shield Logic 🧴
EGCG does not function as a moisturizer or occlusive. Instead, it protects the skin’s lipid barrier indirectly by reducing oxidative damage that weakens barrier integrity over time.
- Acts upstream of barrier breakdown
- Preserves ceramide and lipid stability
- Pairs exceptionally well with barrier-repair ingredients
Water-Based vs Oil-Based Antioxidants 💧🆚🛢️
| Aspect | EGCG (Water-Based) | Vitamin E (Oil-Based) |
|---|---|---|
| Primary Protection Zone | Cellular & aqueous environments | Lipid membranes & oils |
| Ideal Use Time | AM defense | PM repair |
| Skin Feel | Light, breathable | Rich, nourishing |
Climate-Smart Usage 🌦️
EGCG adapts well to climate-driven skin stress, especially pollution and heat.
- Excellent for hot, humid, polluted environments
- Lower concentrations recommended in cold, dry weather
- Ideal antioxidant anchor for tropical morning routines
Expectation Timeline ⏳
