Ethosomes for Curcumin and Piperine Cutaneous Delivery to Prevent Environmental-Stressor-Induced Skin Damage

Area of Science:

• Dermatology
• Nanotechnology
• Pharmacology

Background:

• Diesel particulate matter poses significant risks to human skin health.
• Plant-derived compounds like curcumin (CUR) offer antioxidant and anti-inflammatory benefits but suffer from poor bioavailability.
• Piperine (PIP) can enhance CUR's pharmacokinetic properties and efficacy.

Purpose of the Study:

• To investigate ethosomes (ETs) for enhanced delivery of CUR and PIP to protect skin against diesel particulate matter (DPM) induced damage.
• To evaluate the potential of CUR and PIP loaded ETs for topical application in mitigating pollution-related skin damage.

Main Methods:

• Ethosomes (ETs) were formulated and characterized for size, morphology, and encapsulation efficiency.
• In vitro drug diffusion studies using Franz cells were conducted.
• Antioxidant activity was assessed.
• Ex vivo studies on human skin explants exposed to diesel engine exhaust were performed.

Main Results:

• Ethosomes demonstrated successful encapsulation and enhanced skin permeation of CUR.
• Combined CUR and PIP in ETs significantly increased antioxidant activity.
• Ex vivo studies confirmed that drug-loaded ETs prevent structural skin damage induced by diesel engine exhaust.

Conclusions:

• Ethosomes are a promising nanocarrier system for topical delivery of CUR and PIP.
• The combination of CUR and PIP within ETs offers enhanced protection against environmental stressors like diesel particulate matter.
• This formulation holds potential for preventing exogenous stressor-induced skin damage.
