A liquid crystal application in skin care cosmetics

Area of Science:

• Dermatology and Cosmetic Science
• Materials Science
• Biochemistry

Background:

• Stratum corneum intercellular lipids are crucial for skin hydration, cell adhesion, and reducing transepidermal water loss.
• These functions rely on the self-organizing properties of amphiphilic lipid molecules.
• Dry conditions exacerbate transepidermal water loss, particularly in thin skin areas like around the eyes, leading to wrinkles.

Purpose of the Study:

• To develop and evaluate a novel Lamellar Gel skincare product with enhanced skin barrier functions.
• To investigate the skin care characteristics of the Lamellar Gel compared to conventional emulsions.
• To assess the efficacy of the Lamellar Gel in improving skin hydration, occlusion, and wrinkle reduction.

Main Methods:

• Development of a Lamellar Gel containing a synthesized pseudo-ceramide with structural similarity to natural ceramides.
• Comparative analysis of Lamellar Gel and regular emulsions regarding skin permeability, hydration, and occlusion.
• Clinical assessment of Lamellar Gel's effect on skin hydration and wrinkle recovery, especially under dry conditions.

Main Results:

• The Lamellar Gel formed self-organizing structures analogous to natural stratum corneum lipids, demonstrating high skin affinity.
• Lamellar Gel exhibited superior skin hydration and occlusion compared to standard emulsions.
• Prompt recovery of wrinkles and prolonged stratum corneum hydration were observed after treatment with Lamellar Gel.

Conclusions:

• The Lamellar Gel's structural mimicry of natural skin lipids underpins its enhanced moisturizing and protective capabilities.
• This innovative formulation offers a dual benefit of initial hydration and long-lasting occlusion, surpassing conventional emulsions.
• Lamellar Gel presents a promising therapeutic approach for managing dry skin conditions and mitigating wrinkle formation.
