Key Points:

• Initial studies on Enzymatically Modified Isoquercitrin (EMIQ) highlight its strong antioxidant capabilities and protective effects against collagen degradation, underpinning its anti-aging properties.
• EMIQ’s effectiveness against UV damage and aging was demonstrated through in-vitro analyses and a 28-day clinical trial, showcasing improved skin health.
• The research supports EMIQ’s potential as an anti-photoaging ingredient in skincare formulations, offering a solution to mitigate the signs of aging.

Overview

The scientific community is looking for ways to combat signs of aging, especially those caused by environmental factors like UV radiation. They are exploring the potential of natural compounds for this purpose.

Enzymatically Modified Isoquercitrin

Researchers focussed on enzymatically modified isoquercitrin (EMIQ), a flavonoid derivative of isoquercitrin, for its anti-aging properties. Research suggests that EMIQ may have promising anti-aging capabilities, including antioxidant properties, the ability to protect against collagen degradation, and effectiveness in enhancing skin health. 

High-Performance Liquid Chromatography of Enzymatically-modified Isoquercitrin

This study delves into the anti-aging capabilities of enzymatically-modified isoquercitrin (EMIQ). Initial High-Performance Liquid Chromatography (HPLC) analyses of EMIQ revealed a composition of 1–12 glucosides and 10.7% pentahydroxyflavonoids, indicating strong antioxidant properties.

In-vitro analysis

In-vitro experiments with UVA-exposed human dermal fibroblasts (HDFa) showcased EMIQ’s ability to mitigate collagen degradation, suggesting its protective role in maintaining skin structure. EMIQ’s effectiveness was attributed to its modulation of the TGFβ/Smad and MMP1 pathways, crucial for collagen preservation. Further analysis using the T-Skin™ model demonstrated EMIQ’s capacity to shield the epidermis and dermis from UV damage.

Clinical studies

After promising in-vitro results, a 28-day clinical trial involving 30 volunteers between 31 and 55 years confirmed EMIQ’s anti-aging benefits. Participants who used a skincare Essence containing EMIQ exhibited notable improvements. These improvements include reduced facial trans-epidermal water loss, decreased skin roughness, and enhanced skin elasticity. 

Implications

These clinical findings highlight the substantial promise of EMIQ as an effective anti-photoaging ingredient in cosmetic formulations.
