Mussofi serum: The essence of our patented innovation

Our face serum is not like other skincare products. It's the core of our patent filed in France, the pure concentrate of our scientific innovation designed exclusively for black and mixed-race skin.

Unlike "universal" cosmetics adapted at the last minute, our formulation has undergone... in-depth research on the physiological specificities of dark skin: intense dehydration, reactive hyperpigmentation, and the need for radiance without aggression.

An ultra-concentrated formula in active ingredients

With 98% of ingredients are of natural origin , including organic glycerin , our face serum is a concentrated effectiveness in an ultra-light, transparent gel texture.

Unique feature: Our 4 patented active ingredients (Ascorbyl Glucoside, Shikimic Acid, Alpha-Glucan Oligosaccharide and Sodium Hyaluronate) work in synergy to simultaneously meet all the needs of dark skin.

🔬 Our patent: A scientific innovation at the service of your skin

The synergistic partnership that changes everything

In a way Unexpectedly , our research team observed that the precise combination of these four compounds allowed for:

✅ Relieve the tension of dry skin resulting from intense dehydration of dark skin

✅ Improve hydration status skin from "dehydrated" to "less dehydrated" through regular application

✅ Reducing hyperpigmentation spots safe and non-irritating

This discovery was the subject of a patent issued recognizing the originality and effectiveness of our approach for black and mixed-race skin.

🌍 Understanding your skin's specific needs

Why do black skin types become so dehydrated?

Our patent explains a little-known phenomenon:

Black and mixed-race skin possesses a denser stratum corneum and one thicker dermis , which facilitates cell renewal and makes them less susceptible to aging.

But there is a price to pay: To ensure effective perspiration and regulate body temperature in hot climates (a legacy from our African ancestors), these skins... They dehydrate extremely , even in a dry and temperate European climate.

Result : Tight skin, a dull and greyish complexion, and a feeling of constant discomfort.

The trap of reactive hyperpigmentation

Darker skin tones produce more melanin and are particularly affected by the appearance of brown spots resulting from an overproduction of melanin triggered by:

• An insect bite

• Irritation (shaving, friction)

• An acne pimple

• Any inflammation

Each micro-aggression against the skin can leave a post-inflammatory spot which persists for months, even years.

💧 Our ingredient list broken down, ingredient by ingredient

Demineralized Water - Aqua

The ultra-pure base of our gel

Why demineralized water?

Tap water contains minerals (calcium, magnesium) and chlorine that can interfere with delicate active ingredients like vitamin C or irritate sensitive skin. We use water purified to guarantee that only our 4 patented active ingredients act on your skin.

His role: The base of the serum-gel transports and diffuses the water-soluble active ingredients into your epidermis.

---

Organic Glycerin

Certified organic natural moisturizer

Origin : 100% organic vegetable, obtained by saponification of certified organic vegetable oils.

Why a high concentration?

Our serum contains a substantial concentration of organic glycerin to compensate for the severe dehydration characteristic of dark skin identified in our patent.

What is a humectant?

A humectant It is a molecule capable of capturing water from the atmosphere and retaining it in the upper layers of the skin. It's like an invisible sponge that keeps your skin hydrated from within.

His role:

• It captures atmospheric water and retains it in the epidermis.

• Maintains the intense hydration needed for dark skin.

• Softens and smooths the skin

• Property occlusive (limits water evaporation)

• Creates the comfortable gel texture of the serum

Certification: 100% organic glycerin, organic content of the formula: 57% (excluding water).

---

Xanthan Gum

Natural gelling agent through fermentation

Origin : 100% natural, polysaccharide obtained by bacterial fermentation of glucose by Xanthomonas campestris .

Why a gel rather than a liquid?

The gel texture allows for a precise application on the areas to be treated (spots, dehydrated areas) and a gradual penetration active ingredients. The gel stays where you apply it without running.

His role:

• Transforms the liquid serum into a transparent gel

• Ensures stable viscosity over time

• Allows for targeted and precise application

• Improves the distribution of active ingredients on the skin

• 100% biodegradable

🌟 The 4 patented active ingredients: The heart of our innovation

1. Ascorbyl Glucoside - Ascorbyl Glucoside

Stabilized vitamin C: the star anti-dark spot active ingredient of our patent

Why is this asset at the heart of our patent?

Pure vitamin C is exceptionally effective against hyperpigmentation, but it oxidizes within hours in an aqueous formula. Ascorbyl glucoside solves this problem while offering clinically proven efficacy on dark spots in dark skin.

How does this "smart vitamin C" work?

A glucose molecule protects vitamin C during storage. Upon contact with your skin, the enzyme α-glucosidase (naturally present in your epidermis) breaks the bond and releases the pure vitamin C directly where it acts.

The 4 patented actions on black and mixed-race skin:

1. Anti-hyperpigmentation spot action

• Inhibits tyrosinase (enzyme that produces melanin)

• Lightens existing melanin in the brown spots

• Visibly reduces blemishes after 12 weeks of daily use

• Targeted action on post-inflammatory hyperpigmentation

2. Anti-aging action

• Stimulates the synthesis of collagen (firming protein)

• Stimulates the synthesis of hyaluronic acid natural

• Improves wrinkles and skin texture

• Firms and smooths the skin

3. Protective antioxidant action

• Neutralize the free radicals (molecules that accelerate aging)

• Protects against UV damage (even though dark skin is naturally protected)

• Protects cellular DNA from oxidation

• Anti-pollution shield

4. Moisturizing action

• Strengthens the skin barrier

• Improves the skin's ability to retain water

• It complements the action of glycerin and hyaluronic acid.

Clinical results: Study on 46 women applying an Ascorbyl Glucoside-based lotion twice a day for 12 weeks: significant reduction in spots and improvement in radiance score.

2. Shikimic Acid - Shikimic Acid

The gentle exfoliant from Asia: the multifunctional active ingredient of our patent

Origin : 100% natural, extracted from the fruit of the star anise ( Illicium verum ), medicinal plant of the ancestral Chinese pharmacopoeia.

Why is shikimic acid included in an anti-blemish serum?

Black and mixed-race skin accumulates more dead cells on the surface, creating a greyish veil which masks natural radiance and prevents active ingredients from penetrating effectively. Exfoliation is therefore essential, but it must be gentle to avoid causing inflammation (and therefore new spots).

The problem with classic AHAs

Traditional fruit acids (glycolic acid, lactic acid) are effective but can be too aggressive for reactive black and mixed-race skin, triggering inflammation and post-inflammatory hyperpigmentation.

The patented solution: shikimic acid

Exfoliation 24% higher than glycolic acid while being much less irritating . After 24 hours, the area treated with glycolic acid was irritated and flaky, while the area treated with Shikimic Acid was normal.

The 5 patented actions:

1. Gentle and effective exfoliation

• Eliminates the keratinocytes (dead cells) surface

• Smoothes the skin texture

• Reveals the radiance of the masked complexion

• Prepares the skin to receive other active ingredients

2. Antibacterial and anti-acne action

• Inhibits Propionibacterium acnes (acne bacteria)

• MIC (minimum inhibitory concentration) between 1-2%

• Prevents imperfections and therefore post-acne spots

3. Anti-inflammatory action

• Soothes irritations

• Reduces redness (visible even on dark skin)

• Prevents inflammatory hyperpigmentation

4. Anti-enzymatic action

• Inhibits the lipases (enzymes that break down lipids)

• Reduces the production of free fatty acids

• Controls sebum

5. Deodorizing action

• Reduces body odor by inhibiting the enzymes responsible

• 98% inhibition in 15 minutes (twice as much as Triclosan)

Certification: Cosmos approved, 100% natural origin.

3. Alpha-Glucan Oligosaccharide - Alpha-Glucan Oligosaccharide

The protective prebiotic: the "balancing" active ingredient of our patent

Origin : Prebiotic of biotechnological origin obtained by enzymatic biocatalysis from plant substrates.

What is a prebiotic?

A prebiotic is a specific "food" for the good bacteria on your skin. Unlike probiotics (which provide live bacteria), prebiotics selectively feeds the beneficial bacteria already present on your skin.

Why protect the microbiota in an anti-blemish serum?

THE skin microbiota (the collection of billions of microorganisms that live on your skin) is the invisible guardian of your skin health. When it is unbalanced:

• Natural defenses weaken

• The skin becomes reactive and inflamed

• Imperfections are multiplying

• Every imperfection = a future stain on black skin

Our patent includes this prebiotic to ensure that the anti-blemish treatment does not disrupt your skin's ecosystem.

How does Alpha-Glucan Oligosaccharide work?

Its molecular structure with specific bonds α-(1-6) and α-(1-2) It can only be digested quickly by good bacteria. It's like a buffet accessible only to select guests.

The 3 patented actions:

1. Bioselective substrate for the microbiota

• It preferentially feeds commensal (beneficial) bacteria: Lactobacillus pentosus , Micrococcus kristinae , Corynebacterium xerosis

• Does NOT feed opportunistic bacteria: Staphylococcus aureus , Propionibacterium acnes , Gardnerella vaginalis

• Does NOT encourage the growth of yeasts ( Candida albicans , Malassezia furfur )

2. Rebalancing the microbial landscape

• +21% Actinobacteria (producers of natural antibiotics)

• +36% of Firmicutes

• +146% of Staphylococcus epidermidis (protects against pathogens)

• Restores the skin's natural balance

3. Strengthening natural defenses

• Stimulates the production of antimicrobial peptides :

  • hBD2 (β-defensin 2): +53%

  • hBD3 (β-defensin 3): +153%

• Activates innate skin immunity

• Provides lasting protection for the skin's ecosystem

Certification: Ecocert Cosmos approved, suitable for sensitive and atopic skin.

4. Sodium Hyaluronate - Sodium Hyaluronate

The "molecular sponge": the hydrating active ingredient of our patent

Origin : Hyaluronic acid high molecular weight obtained by biotechnological fermentation from French wheat grown in Champagne-Ardenne.

Why is hyaluronic acid crucial for dark skin?

Our patent identifies the severe dehydration as a major concern for dark skin. High molecular weight hyaluronic acid is the most powerful moisturizer in cosmetics: it can absorb 1000 times its weight in water .

What is "high molecular weight"?

THE molecular weight measures the size of molecules. A high molecular weight (1-1.4 MDa) means that the molecules are very large : they cannot penetrate the skin and remain on the surface.

Is this a problem? No, that's exactly what we're looking for! By remaining on the surface, hyaluronic acid forms a Invisible protective film which traps water.

The 3 patented actions:

1. Formation of a moisturizing film

• Remains on the surface of the epidermis (molecules too large to penetrate)

• Form a invisible veil which retains water

• Protective "second skin" effect

2. Limitation of transepidermal water loss (TEWL)

• TEWL Transepidermal Water Loss (TEWL) = loss of water through the skin

• The hyaluronic acid film acts as a barrier

• The water remains trapped in your epidermis

• Your skin stays hydrated for longer

3. Long-lasting hydration for up to 24 hours

• Maintaining skin moisture balance

• Soft, bouncy and comfortable skin

• Relieves the pulling sensations identified in our patent

• "Baby skin" effect

Certifications: Cosmos approved, Halal, suitable for vegans.

🛡️ Supporting ingredients: Stability and safety

Aqua & Sodium Benzoate & Potassium Sorbate

The bio-compatible preservative system

Origin : Preservatives of natural origin in aqueous solution.

Why are there preservatives in a serum?

A water-based serum rich in active ingredients is a perfect environment to prevent the growth of bacteria, yeasts and molds. Without preservatives, your serum would become dangerous within days.

The dual-action system:

Sodium Benzoate (Sodium benzoate): Salt of benzoic acid naturally present in certain fruits (cranberries). Effective against yeasts and bacteria.

Potassium Sorbate (Potassium sorbate): Salt of sorbic acid naturally present in rowan berries. Effective against molds and yeasts.

His role:

• Broad spectrum antimicrobial protection

• Ensures the microbiological safety of the serum

• Ecocert approved for organic cosmetics

• Stable and efficient at room temperature

Citric Acid - Citric Acid

The natural pH adjuster

Origin : 100% natural, citric acid obtained by biotechnological fermentation from plant materials (corn, tapioca, cassava).

What is pH and why is it crucial?

THE pH (potential of Hydrogen) measures the acidity or alkalinity of a product on a scale of 1 to 14:

• pH < 7 = acidic

• pH = 7 = neutral

• pH > 7 = basic (alkaline)

The skin has a acid mantle natural with a pH between 4.5 and 5.5 which protects it against pathogenic bacteria and maintains the integrity of the skin barrier.

Why adjust the pH of our serum?

1. Asset efficiency Some active ingredients, such as Ascorbyl Glucoside, only work at a specific pH level.

2. Effectiveness of preservatives The Benzoate/Sorbate system is optimal at acidic pH

3. Respect for the skin A pH that is too high destabilizes the acid mantle

4. Formula stability pH determines long-term stability

His role:

• Adjust the serum pH to approximately 5.5 (close to skin pH)

• Guarantees the effectiveness of the 4 patented active ingredients

• Optimizes the action of preservatives

• Respects the skin's physiological balance

• Improves the stability of the formula

Bonus: Citric acid also possesses properties antioxidants lightweight and protective of sensitive active ingredients.
