Pigmentation and Oxidative Stress: Why One Product Isn't Enough and How to Build Protection in Layers

Two Sides of the Same Problem: Pigmentation and Oxidative Stress
When we talk about hyperpigmentation, most people think of melanin and sun exposure. That's a good start, but only a start.
Uneven skin tone is actually caused by the interplay of two interconnected phenomena: excessive melanin production (triggered by UV radiation, hormonal changes, or inflammation) and oxidative stress—a chronic excess of free radicals that damage cell structures, disrupt natural skin renewal, and directly stimulate melanocytes to increased activity.
This relationship is crucial: oxidative stress and pigmentation reinforce each other. UV radiation generates free radicals → free radicals activate melanin production → melanin accumulates in the basal layer → spots form on the surface. At the same time, oxidative cell damage slows down the natural skin renewal that would gradually even out pigment irregularities.
Therefore, a real solution must work on both fronts simultaneously: protecting against oxidative stress and blocking the formation of new pigment, both internally and externally.
How UV Radiation Changes the Skin – The Science Behind Everyday Damage
Ultraviolet radiation is responsible for the vast majority of uneven skin tone that women experience after the age of thirty. It's not just the result of summer tanning; it's the cumulative effect of daily exposure, which occurs even through a window, on a cloudy day, or while moving around the city.
UVB radiation damages surface cells and causes visible redness. UVA radiation penetrates deeper, damaging collagen fibers and stimulating melanocytes to produce pigment without causing an immediately visible reaction. And blue light from screens? It is also now shown to contribute to oxidative stress in the skin.
The result is photo-damaged skin: uneven tone, loss of natural freshness, and the gradual formation of pigment spots on areas most frequently exposed to radiation.
Photo-damage is not inevitable. It is a process that can be significantly slowed down if we protect the skin at all levels where it occurs.
Pomegranate and Ellagic Acid: Polyphenols with Something to Say
Pomegranate (Punica granatum) is among the most researched fruits in relation to skin health. Its power lies in the concentration of polyphenols, especially ellagic acid, which has a specific relationship with melanogenesis.
Ellagic acid inhibits the enzyme tyrosinase, a key catalyst in the melanin production process. At the same time, it acts as a powerful antioxidant that neutralizes free radicals before they can stimulate melanocytes to overproduce pigment.
But that's not all. Science now shows that pomegranate polyphenols activate sirtuin pathways, enzymes regulating cellular metabolism and natural renewal, which are associated with longevity and vital cell function. Activated sirtuins support cellular regeneration and contribute to the skin's ability to better and faster renew its own structure.
Esthe Pro Labo Zakuro – Japanese-Persian Fermentation for Radiant Skin
Zakuro is a premium, new-generation fermented paste made from the highest quality Persian pomegranates with a more than three-year fermentation process. This time-consuming process is not just tradition—fermentation increases the bioavailability of active ingredients and enriches the product with probiotic metabolites.
Each Zakuro sachet contains:
Pomegranate with a concentration of ellagic acid and polyphenols for natural support of even skin tone and protection against oxidative stress.
Herbzyme 113 ORAX – a fermented blend of 113 herbs with 82 strains of lactobacilli for gut microbiome balance, whose influence on skin health we described in the article on the gut-skin axis. Dates as a natural source of energy, minerals, and amino acids. Fruit juices and extracts (citrus, grape, yuzu, ume) for a comprehensive antioxidant spectrum.
Zakuro is not a one-dimensional product focused solely on skin. It is internal nutrition that simultaneously cares for the microbiome, provides energy, and, through polyphenols and ellagic acid, supports a naturally radiant and even skin tone.
How to use: 1-2 sachets daily. Can be consumed directly or mixed with water, yogurt, or another beverage.
Internal Photoprotection: Inner Coat and Patented Complexes
Protection against UV radiation does not have to occur only on the skin's surface. Science today confirms that certain substances administered internally can strengthen the skin's natural resistance to sun radiation at the cellular level even before the radiation reaches the cells and causes damage.
Esthe Pro Labo Inner Coat – Biotechnological Protection from Within
Inner Coat from Esthe Pro Labo is a Japanese dietary supplement specifically designed for internal photoprotection. It is based on two patented complexes:
Nutrox Sun® – an exclusive extract of grapefruit and rosemary developed after more than ten years of research. It contains three types of polyphenols with strong antioxidant properties. It protects cell membranes from oxidative damage caused by UVB radiation, slows down the onset of pigment reactions to sun exposure, and supports the viability of cells exposed to radiation.
AG Herb MIX™ – a complex of carefully selected plant extracts (dokudami, Atlantic hawthorn, Roman chamomile, grape leaves) that actively prevents the manifestations of photo-damage and mitigates the negative effects of sun radiation on cellular processes.
Pearl powder (Nacre) – a traditional Japanese ingredient with a modern confirmed effect: it supports the renewal of skin cells, contributes to evening out skin tone, and stimulates natural collagen production.
Inner Coat does not create a barrier on the surface. It creates one within the body, where the real battle against pigmentation and photo-damage begins.
How to use: 2 capsules daily after meals, with water.
External Protection with Exosomes: Ex-Some UV Cream SPF 36 PA
Internal protection and antioxidants come from within, but the skin also needs a physical shield on its surface. Ex-Some UV Cream SPF 36 PA goes significantly beyond a conventional sunscreen product.
The product name combines two key words: exosomes and UV protection. And it is precisely their combination that makes this cream something unparalleled on the market.
Exosomes are nanoparticles naturally secreted by cells that serve as a biological transfer system, carrying active substances, growth factors, and signaling molecules directly to target skin cells. In the context of UV protection, this means that the cream simultaneously protects the skin from radiation and actively regenerates cellular processes that sun exposure disrupts.
The result is a threefold function in one product: UV protection (SPF 36, PA rating for UVA radiation), cellular regeneration through exosomes, and natural skin tone evening thanks to the support of healthy cellular processes.
Its light, non-sticky texture with no white cast is suitable for daily use as the final step in your routine and as a make-up primer.
How to apply: As the last step of your morning routine, before make-up. Apply to face and neck, gently massage in.
Oxidative Stress and Cellular Energy: A Deeper Layer of Protection
Protection against pigmentation and photo-damage has another dimension that is less talked about, yet it determines how quickly cells regenerate and how effectively they manage oxidative stress: the state of mitochondria and cellular energy metabolism.
Mitochondria are the energy centers of every cell. Their health directly influences how quickly skin cells renew, how effectively they repair damaged structures, and how well they defend against oxidative stress. If mitochondria function suboptimally, cellular renewal slows down, and the manifestations of photo-damage and pigmentation accumulate faster.
Esthe Pro Labo Proton – Molecular Hydrogen and Minerals from Miyakojima
Proton is a premium Japanese dietary supplement based on a patented form of hydrogen bound to natural minerals from the geologically unique island of Miyakojima, a place renowned for its corals and exceptionally pure, calcium-rich underground waters.
Molecular hydrogen is one of the smallest and most permeable antioxidants known to science. Due to its miniature size, it penetrates cell membranes and reaches mitochondria directly, where it selectively neutralizes the most aggressive types of free radicals (hydroxyl radicals and peroxynitrite) without disrupting the natural oxidative processes necessary for cellular functioning.
Proton combines this hydrogen protection with a mineral complex: hydrocalcite from Miyakojima, calcium from seaweed, and magnesium sulfate, which together support electrolyte balance and mitochondrial function.
Why is this relevant for the skin? Healthy mitochondria = faster cellular regeneration = more effective repair of photo-damage = naturally smoother and more even tone. Proton also contributes to reducing the visibility of dark circles under the eyes, which are also associated with oxidative stress in the skin.
How to use: 2-4 capsules daily, with lukewarm water.
Deazaflavin HydroHyper – on the Border of Science and Everyday Vitality
Deazaflavin HydroHyper is a product developed in collaboration with leading research institutions, including the Karolinska Institutet, and represents one of the most advanced supplements in the byFEMME portfolio.
The active ingredient is 5-deazaflavin, a flavin derivative structurally related to the coenzyme NAD⁺. NAD⁺ is a key molecule for cellular energy metabolism: it participates in mitochondrial energy production (ATP), regulates sirtuin pathways, and plays a crucial role in the natural protection of cells against oxidative damage.
NAD⁺ levels in cells naturally decline with age, and with them, the efficiency of cellular metabolism, the speed of regeneration, and the ability to manage oxidative stress. 5-deazaflavin, as a structural analog of NAD⁺, supports key metabolic pathways and contributes to protecting cells from oxidative stress.
Nano-absorption technology with olive oil as a natural carrier ensures maximum bioavailability of the active substance – 30 mg of deazaflavin in one capsule.
Deazaflavin HydroHyper is not an everyday vitamin. It is a premium functional supplement for those who want to support cellular vitality at the most fundamental metabolic level, and who understand that radiant skin and healthy cells are two sides of the same coin.
How to use: 1 capsule daily, ideally in the evening.

Pigmentation is a systemic problem – and requires a systemic response
Pigment spots don't appear overnight and won't disappear overnight. They are the result of processes occurring at the cellular level of oxidative stress, UV damage, slowed regeneration, and melanin imbalance.
True protection therefore cannot rely on a single cream or a single supplement. It relies on understanding what is happening in the cells and on a thoughtful combination of substances that respond to these processes, each in its own way.
Zakuro provides polyphenols and fermented nutrition. Inner Coat protects cells from UV damage from within. Ex-Some UV Cream blocks radiation and regenerates the surface. Proton neutralizes free radicals at the mitochondrial level. Deazaflavin HydroHyper supplies cells with energy for efficient renewal.
Five products. One philosophy. Science behind beauty that doesn't stay on the surface.
