Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eyelash enhancing serums using prostaglandins cause cosmetic side effects, and there is a need for a healthy, targeted, and concentrated delivery method to promote eyelash growth without prostaglandins.
Innovation Solution
A chitosan-biotin composition and application device that includes a chitosan biotin polymer with a 1:1 to 1:10 ratio, applied via a brush with soft bristles, to stimulate eyelash growth and enhance appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If prostaglandins are used to promote eyelash growth, then eyelash growth is effective, but cosmetic side effects occur
Solution Approach 1:
The patent extracts and eliminates prostaglandins from the eyelash growth formulation, replacing them with chitosan-biotin polymer that achieves similar growth effects without the harmful cosmetic side effects. This extraction principle removes the harmful substance while preserving the beneficial function.
Solution Approach 2:
The patent changes the chemical composition parameters by substituting prostaglandins with chitosan-biotin polymer having specific molecular weight and ratio characteristics. This parameter change enables achieving eyelash growth without the harmful effects associated with prostaglandin use.
2Productivity
If conventional serums are applied to promote eyelash growth, then growth stimulation is achieved, but targeted delivery is insufficient
Solution Approach 1:
The patent applies local quality by formulating chitosan-biotin polymer with specific molecular weight and biotin-to-chitosan ratio characteristics that enable concentrated delivery directly to the eyelash root area. The formulation is designed to provide high local concentration at the application site while maintaining safety.

AI summary
A method for promoting eyelash growth may include applying an effective amount of a chitosan-biotin composition to the eyelashes and preferably to the eyelash line of a patient or recipient to promote the growth and enhance the appearance of the eyelashes of a mammalian subject, such as a human user, patient, recipient, etc. The chitosan-biotin composition may include a chitosan biotin polymer having approximately a 1:1 to 1:10 chitosan to biotin ratio, in which the chitosan-biotin composition may include approximately between 0.001% to 0.1% of the chitosan biotin polymer.
