Healthy-looking skin depends not only on surface care, but also on how cells exchange biological signals, maintain energy and support renewal over time.

Exosomes are extracellular vesicles involved in cell-to-cell communication. They carry proteins, lipids and nucleic acids, helping cells transfer information and coordinate their activity.

The formula uses PUA Exosome® technology with bioactives derived from placenta, umbilical cord and amnion.

Its key feature is concentration: 218 billion exosomes per gram.

Three biological sources work together in the formula:

Placenta — rich in amino acids, enzymes, vitamins and growth-factor related components.

Umbilical Cord — naturally high in moisture-supporting compounds such as hyaluronic acid and chondroitin sulfate.

Amnion — a source of cytokines and growth factors, including EGF, FGF and GDF-11.

Together, these components are designed to support the biological processes behind:

Hydration & Skin Comfort
for smoother, more supple-looking skin.

Firmness & Elasticity
for skin structure, resilience and a firmer-looking appearance.

Cellular Energy
to support inner vitality and skin renewal.

Metabolic health includes blood sugar control, blood lipid balance, liver fat regulation, inflammatory status, and gut microbiome composition. These areas are closely linked, which is why modern research often looks at several metabolic markers together.
Fermented Korean ginseng is being studied because fermentation changes the ginsenoside profile of ginseng.
⠀
Ginsenosides are the main active compounds in ginseng. Many of them are poorly absorbed in their original form. After digestion, intestinal bacteria and enzymes can convert them into smaller metabolites that may be easier for the body to absorb and use. A 2025 review describes this conversion as an important part of ginsenoside metabolism and bioavailability.
(Wang et al., 2025.)
⠀
Fermentation can change this profile before digestion. During fermentation, some major ginsenosides can be converted into rare forms, including Rg3, Rh2, Rk1, Rg5, and compound K. These rare ginsenosides are studied because they may have better bioavailability and stronger biological activity than some major ginsenosides found in non-fermented ginseng.
⠀
In a 2025 animal study, fermented ginseng powder enriched with rare ginsenosides was tested in mice fed a high-fat diet. The researchers reported lower body weight gain, improved blood lipid and glucose markers, reduced fat accumulation in the liver and abdominal fat tissue, and lower inflammatory markers, including IL-1, IL-6, and TNF-α. The study also showed changes in markers involved in fat metabolism and energy regulation. (Tai et al., 2025.)
⠀
A 2026 animal study tested fermented red ginseng in aged mice. The researchers reported improved insulin homeostasis, activation of insulin-related signaling in the liver, reduced pro-inflammatory cytokine expression, and changes in gut microbiome composition. (Lee et al., 2026.)
⠀
These findings explain why fermented Korean ginseng is discussed in metabolic research. Fermentation changes ginsenosides, and these changes may be relevant to glucose regulation, lipid metabolism, liver function, inflammatory response, and gut microbiota.

Stable blood glucose regulation is a central factor in maintaining metabolic health. Elevated fasting and postprandial glucose levels are associated with insulin resistance, vascular dysfunction, and accelerated formation of advanced glycation end products (AGEs), which contribute to chronic inflammation and structural damage in tissues.

SIRTMAX® is a patented extract of Kaempferia parviflora, a plant traditionally used in Southeast Asia to support metabolic function and circulation. Its activity is supported by modern research focused on key metabolic pathways.

The extract is involved in glucose regulation, reduction of glycation processes, and support of vascular function. Particular relevance is attributed to its interaction with SIRT1, a pathway associated with cellular energy regulation and stress response.

Clinical observations indicate improvements in glucose markers, reduced AGE formation, and positive trends in vascular function.

Multi-Component Support

The formula is supported by additional ingredients with complementary mechanisms:
•Banaba — supports glucose transport into cells
•Salacia — slows carbohydrate absorption
•Mulberry — reduces post-meal glucose spikes
•Bitter melon — supports insulin sensitivity

The formulation is designed to support glucose control, reduce glycation, and maintain metabolic balance.

Persistent breakouts of acne in adults are rarely just about clogged pores or skincare mistakes. In most cases, they reflect a combination of underlying processes that go beyond the surface.
Many people focus only on topical care - cleansing, acids, retinoids. Skin may look better for a while, but breakouts tend to return. Adult acne is often not only a surface-level issue.

𝘚𝘦𝘷𝘦𝘳𝘢𝘭 𝘪𝘯𝘵𝘦𝘳𝘯𝘢𝘭 𝘮𝘦𝘤𝘩𝘢𝘯𝘪𝘴𝘮𝘴 𝘤𝘢𝘯 𝘪𝘯𝘧𝘭𝘶𝘦𝘯𝘤𝘦 𝘴𝘬𝘪𝘯 𝘤𝘰𝘯𝘥𝘪𝘵𝘪𝘰𝘯 𝘢𝘵 𝘵𝘩𝘦 𝘴𝘢𝘮𝘦 𝘵𝘪𝘮𝘦:
⠀
1. Fluctuations in blood glucose: leads to increased sebaceous gland activity
2. Hormonal signaling: leads to higher sebum production
3. Inflammatory responses: leads to initiation and persistence of breakouts
4. Oxidative stress: leads to cellular damage and slower recovery
5. Liver load: leads to reduced efficiency of metabolic waste processing
⠀
As a result, the skin becomes congested more easily, inflammation lasts longer, and recovery slows down.
⠀
Why skincare alone doesn’t always lead to stable results?
⠀
Topical products act on the outer layer of the skin - they cleanse, regulate cell turnover, and partially reduce inflammation.
⠀
At the same time, internal factors like 𝘴𝘦𝘣𝘶𝘮 𝘱𝘳𝘰𝘥𝘶𝘤𝘵𝘪𝘰𝘯, 𝘣𝘢𝘴𝘦𝘭𝘪𝘯𝘦 𝘪𝘯𝘧𝘭𝘢𝘮𝘮𝘢𝘵𝘪𝘰𝘯, 𝘢𝘯𝘵𝘪𝘰𝘹𝘪𝘥𝘢𝘯𝘵 𝘤𝘢𝘱𝘢𝘤𝘪𝘵𝘺 𝘢𝘯𝘥 𝘮𝘦𝘵𝘢𝘣𝘰𝘭𝘪𝘤 𝘳𝘦𝘨𝘶𝘭𝘢𝘵𝘪𝘰𝘯 remain unchanged. This is why results can be incomplete or inconsistent.
⠀
What is considered in a more comprehensive approach?
⠀
— modulation of inflammatory processes
— antioxidant support
— liver function support
— influence on sebum regulation and keratinization

The word “detox” is usually understood as something that removes “toxins”, “slags”, or harmful substances from the body.
From a biological point of view, this understanding is inaccurate.

In 2024, a study published in the Journal of Hazardous Materials (Marchiandi et al.) examined endocrine-disrupting chemicals in non-alcoholic beverages and their relation to packaging materials.

The researchers analysed 162 products and found that around 90% contained at least one endocrine-active compound. The highest levels were detected in drinks packaged in metal cans, particularly bisphenols. In some scenarios, estimated daily intake exceeded the updated safety threshold established by the European Food Safety Authority.

The study did not discuss detox programs or ways to remove these substances from the body. It focused on exposure. The key point is that this exposure is chronic and unavoidable for most people, and it begins where food and drinks first interact with the body — in the gastrointestinal tract.

Environmental compounds such as bisphenols or PFAS are not “flushed out”. There is no physiological mechanism that simply cleans them away. Instead, the body responds through barrier function, immune regulation, inflammatory control, and metabolic processing.

From this perspective, the intestine is not just a digestive organ. It is a major interface between the environment and the body. Its epithelial integrity, microbiome balance, and immune signaling play a central role in how environmental stressors affect overall health.

When people talk about “detox”, what actually matters is not removal of imaginary “slags”, but how well these systems cope with constant environmental load.

OKINAWA Wild Herbs Active Enzymes
• Supports normal intestinal function under everyday environmental stress
• Helps maintain gut barrier integrity and microbiome balance
• Designed to support the body’s response to chronic, low-level environmental exposure
