Solution Overview

Problem

Traditional moisturizing lotions require high energy input for production and do not offer environmentally sustainable options, while existing products often fail to effectively address dry skin issues, leading to symptoms like redness, itchiness, and loss of skin flexibility.

Innovation Solution

A moisturizing gel composition containing humectants like trimethylglycine and glycerin, skin feel agents such as PEG-14M and polyglyceryl-3-laurate, and skin conditioning agents like shea oil, combined with a cosmetically acceptable aqueous carrier, which can be produced at ambient temperatures without external heating, providing improved skin hydration and softness.
