The Skincare Revolution: How Encapsulated Grape Seed Extract Activates Your Skin's Longevity Protein
Discover the science behind ACTIVITISâ„¢ and its groundbreaking approach to anti-aging by targeting PP2A demethylation.
The Skin's Master Regulator
Imagine if your skin had a master switch capable of turning back the clock on aging—a single protein that coordinates your skin's response to environmental damage, regulates hydration, and maintains firmness and elasticity. Recent scientific research has uncovered that such a switch actually exists within our skin cells, and it's called Protein Phosphatase 2A (PP2A). Even more remarkably, researchers have discovered how a novel ingredient derived from grape seeds can influence this switch to provide remarkable anti-aging benefits 1 .
The journey to this discovery began with a challenge: traditional grape seed extract, while beneficial, has limitations in cosmetic formulations due to its dark purple color and limited solubility. Scientists addressed this through an ingenious encapsulation technology, creating what's known as Encapsulated Activated Grape Seed Extract (E-AGSE), commercially referred to as ACTIVITISâ„¢ 1 . This innovation not only improved the ingredient's usability but unexpectedly enhanced its biological activity, opening new frontiers in skincare science that directly targets the molecular mechanisms of skin aging.
The Science of PP2A: Your Skin's Anti-Aging Guardian
The Master Regulatory Protein
Protein Phosphatase 2A (PP2A) is not just another cellular component—it's considered a master regulatory protein that plays a critical role in cellular response to oxidative stress 1 . Think of PP2A as the conductor of a cellular orchestra, coordinating various responses to environmental threats like UV radiation and pollution. It achieves this through a complex structure consisting of three subunits that work together to regulate essential cellular processes 1 .
When PP2A is functioning optimally, it helps maintain skin youthfulness by:
However, when PP2A activity declines, the consequences become visible on our skin in the form of wrinkles, sagging, and dullness.
PP2A Function and Demethylation Process
The Demethylation Problem
The activity of PP2A is precisely controlled through a process called methylation—the addition of a small chemical group (a methyl group) to the protein. This methylation "activates" PP2A, enabling it to perform its protective functions. The problem arises when an enzyme called PME-1 (Protein Phosphatase Methylesterase-1) removes this crucial methyl group through a process called demethylation, effectively "switching off" PP2A's activity 1 6 .
Research has shown that reactive oxygen species (ROS), which are generated by UV exposure and environmental stressors, can trigger PP2A demethylation 1 . This creates a vicious cycle: environmental stress inactivates PP2A, which then reduces the skin's ability to combat further stress. As we age, this cycle accelerates, leading to more pronounced signs of skin aging.
The Encapsulation Breakthrough: A Trojan Horse for Skin Health
Overcoming Formulation Challenges
The researchers faced a significant hurdle: while they had identified Activated Grape Seed Extract (AGSE) as a potent activator of PP2A, its physical properties made it difficult to incorporate into cosmetic products. The extract was a dark purple powder with limited solubility, restricting its use in transparent or light-colored formulations that consumers prefer 1 .
To overcome these challenges, scientists developed an innovative encapsulation system that packages AGSE into microscopic delivery vehicles using:
This combination created what we now know as Encapsulated Activated Grape Seed Extract (E-AGSE), which completely transformed the ingredient's properties while enhancing its biological activity.

The encapsulation process created a novel formulation with reduced color and increased solubility 1 . More importantly, this nanotechnology-based approach offered several scientific advantages:
Higher Solubility

Improved Stability
Enhanced resistance to degradation
Controlled Release
Sustained delivery of active compounds
This final point—enhanced absorption—proved critical. The encapsulation allowed the active flavonoids to penetrate more effectively into the skin layers where they could exert their effects on PP2A, meaning lower concentrations could achieve greater efficacy.
Experimental Evidence: Putting ACTIVITIS to the Test
Methodology and Study Design
To validate the anti-aging benefits of their newly developed E-AGSE, researchers conducted a comprehensive series of experiments combining laboratory models and human clinical trials 1 . The multi-faceted approach included:
Cellular Studies
Using human dermal fibroblasts and epidermal keratinocytes to measure expression of aging and dermal-epidermal junction markers
UVB Protection Assays
Using EpiDermâ„¢ models to measure protection against cytokine release, DNA damage, apoptosis, and skin barrier compromise
Melanogenesis Studies
Using human melanocytes and mushroom tyrosinase to measure reduction in melanin production
Clinical Testing
4-week, 31-subject study on sensitive skin using a 2% E-AGSE Essence
The PP2A demethylation assay specifically measured the extract's ability to prevent PME-1 from removing the crucial methyl group from PP2A. This was done using a radioactive filter binding assay format where PME-1 was incubated with the extract before adding radioactive-labeled methylated PP2A 1 .
Clinical Results: Measurable Anti-Aging Benefits
The 4-week clinical trial on human subjects demonstrated significant improvements across multiple skin parameters. The results below show the percentage improvement for key anti-aging indicators:

Multiple Mechanisms of Action: How ACTIVITIS Works
Protecting PP2A from Demethylation
At the molecular level, E-AGSE works primarily by inhibiting the demethylation of PP2A 1 . The encapsulated grape seed extract contains specialized flavonoids that interfere with PME-1, the enzyme responsible for removing the activating methyl group from PP2A. This mechanism ensures that PP2A remains in its active, methylated state where it can perform its protective functions.
The significance of this mechanism is profound—by maintaining PP2A in its active form, E-AGSE helps preserve the skin's natural defense systems against environmental stressors that would otherwise accelerate aging.
PP2A Protection Mechanism
Comprehensive Anti-Aging Benefits
Beyond PP2A protection, E-AGSE delivers multiple verified anti-aging benefits through various pathways:
Collagen Boost
Significantly increases production of both Collagen I and III—the key structural proteins that maintain skin firmness and prevent sagging 1 .
Skin Barrier Support
Enhances production of filaggrin, a crucial protein for proper skin barrier function 1 . This strengthens the skin's defense against environmental aggressors and reduces moisture loss.
Brightening Effect
Inhibits tyrosinase activity and reduces melanin production, leading to a more even skin tone and reduced appearance of age spots 1 .
