Science
Mechanism of Action
As a key structural and functional component of keratinocyte cell membranes, Phosphatidylglycerol (PG) regulates inflammation by modulating Toll-like receptor (TLR) signaling, which helps mitigate inflammatory skin conditions such as psoriasis and atopic dermatitis. It also strengthens the skin barrier through optimizing lipid organization and boosting the production of essential skin lipids. Specifically, Dioleoylphosphatidylglycerol (DOPG) stimulates keratinocyte proliferation and enhances mitochondrial function, thereby accelerating wound healing.

Key findings
- 01 Topical formulations containing Phosphatidylglycerol have demonstrated promise in improving skin hydration and facilitating skin barrier recovery in small-scale human trials.
- 02 In a mouse model mimicking psoriasis, topical application of PG successfully ameliorated skin lesions and reduced inflammation.
- 03 Studies show that egg-derived PG accelerates the healing of full-thickness skin wounds, with Dioleoyl Phosphatidylglycerol (DOPG) exhibiting superior efficacy in stimulating keratinocyte proliferation.

The Formula
Formulation
Stability
Phosphatidylglycerol, as a phospholipid, possesses inherent emulsifying properties, which are beneficial for creating stable skincare and haircare emulsions and enhancing the delivery of active ingredients. While a specific optimal pH range for Phosphatidylglycerol itself is not defined, general phospholipid-based emulsions typically exhibit stability across a broad pH spectrum, such as 3.5 to 8.5.
Conflicts
- Should not be used in cosmetic products where N-nitroso compounds may be formed.
Safety
Safety Profile
The CIR Expert Panel has concluded that Phosphatidylglycerol is safe for use in cosmetics within current industry practices and concentrations, up to 50%. It is crucial to avoid its use in cosmetic products where N-nitroso compounds could potentially be formed.
