Psidium guajava and Kunzea ericoides extracts for sebum control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing sebum production and unclogging pores often lead to skin irritation and can result in dry, flaky skin, making them ineffective for treating acne and oily skin conditions.
Innovation Solution
A topical skin composition containing Psidium guajava fruit extract, either alone or in combination with Kunzea ericoides leaf extract, is applied to reduce sebum production and unclog pores, using aqueous or hydroglycolic extracts with water and glycerin, and optionally a preservative, to treat acne and oily skin without causing irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If caustic agents are used to reduce sebum production and unclog pores, then sebum removal effectiveness is improved, but skin irritation increases and skin condition deteriorates (dry and flaky skin)
Solution Approach 1:
The patent changes the chemical parameters of the active ingredient from harsh caustic agents to plant-based extracts (Psidium guajava fruit extract and/or Kunzea ericoides leaf extract). This parameter change maintains sebum removal effectiveness while eliminating skin irritation and dryness associated with traditional caustic treatments
Solution Approach 2:
The patent uses composite plant extract formulations, combining Psidium guajava fruit extract and/or Kunzea ericoides leaf extract with cosmetic-grade carriers. This composite approach provides effective sebum control while the natural plant components and cosmetic carriers work synergistically to prevent skin irritation
2Productivity
If caustic agents are used to unclog pores, then pore clearance is improved, but skin condition deteriorates (dry and flaky skin)
Solution Approach 1:
The patent changes the chemical nature of the active ingredient from drying caustic agents to hydrating plant extracts. Psidium guajava fruit extract and/or Kunzea ericoides leaf extract provide pore unclogging benefits while maintaining skin moisture balance, preventing the dry and flaky skin condition caused by traditional treatments
Solution Approach 2:
The plant-based extracts act as intermediary substances that mediate between the need for pore clearance and the need to maintain skin moisture. These extracts provide a gentle mechanism for removing pore blockages without disrupting the skin's natural moisture barrier
