Microbiome & Skin
By the Lili Margo Team Reading time: 8 min April 20, 2026
Your skin is home to an invisible ecosystem of over a million microorganisms per square centimeter. This skin microbiome is the key to balanced, radiant, and resilient skin. Discover how to preserve it — and how Lili Margo's floral active ingredients are its best allies.
The Skin Microbiome: A Complete Ecosystem in Itself
For a long time, skincare focused on the visible surface: texture, radiance, wrinkles. But in 2026, cosmetic science definitely changed its paradigm. Attention is now focused on what happens beneath the surface: the skin microbiome.
Your skin's microbiome is a living, dynamic community composed of bacteria, fungi, viruses, and yeasts. Far from being invaders, these microorganisms are your most valuable allies. They produce acids that maintain the skin's natural acidic pH (around 5.5), secrete anti-inflammatory molecules, and constitute the first line of defense against pathogenic bacteria.
Did you know?
Your skin contains over 1,000 different species of bacteria. The strain Cutibacterium acnes, often wrongly associated with acne, actually plays a protective role when the microbiome is in balance. It's its imbalance — and not its presence — that causes imperfections.
When this balance is disturbed — by overly aggressive cleansers, overexposure to UV, stress, or an unbalanced diet — the skin becomes more permeable, more sensitive, and more prone to redness, acne, or dryness. This is called skin dysbiosis.
The Invisible Enemies of Your Microbiome
Understanding what disrupts the microbiome is the first step to better protecting it. Aggressions are more numerous than we think — and some are hidden in daily beauty routines.
73% of sensitive skin shows an impoverished microbiome
5.5 ideal pH for a thriving skin microbiome
+23.4% clinically proven collagen synthesis with FLORACTIV20+®
Alkaline pH cleansers
Most classic soaps have a pH of around 9 to 10, well above the skin's natural pH. Regular use destroys the protective flora and weakens the skin barrier. Opt for cleansers formulated with a neutral or slightly acidic pH, with gentle, naturally derived surfactants.
Purifying Floral Foam
Gentle cleanser, formulated with 97% natural ingredients. Preserves the hydrolipidic film and respects your skin's microbial balance.

Disruptive active ingredients to avoid
Certain synthetic chemical active ingredients — parabens, sulfates, occlusive silicones, synthetic fragrances — can disrupt the skin flora in the long term. This is why natural formulation and ingredient transparency have become essential criteria for informed consumers.
Lili Margo expert tip: Carefully read the INCI list of your products. An Ecocert-certified product formulated with 95-97% natural ingredients, like the Lili Margo range, guarantees a composition that respects your skin's ecosystem.
Oxidative stress and pollution
Free radicals generated by urban pollution, UV, and stress directly degrade the diversity of the microbiome. Powerful antioxidant protection — ideally of plant origin — is therefore essential daily to maintain microbial balance.
FLORACTIV20+®: The Perfect Alliance of Flowers and Microbiome
At Lili Margo, we have developed the patented FLORACTIV20+® complex, a unique synergy of 20 flowers selected for their complementary properties. This complex doesn't just act on the surface: it favorably interacts with the skin's microbial environment to strengthen its natural balance.
Unlike isolated active ingredients, the botanical richness of FLORACTIV20+® provides a diversity of polyphenols, flavonoids, and microbiome-compatible essential oils. These molecules nourish beneficial flora without harming protective strains, like an excellent natural prebiotic.
Clinical Study
An independent clinical study conducted on FLORACTIV20+® Floral Awakening Cream shows a +23.4% increase in collagen synthesis after just 4 weeks of use. A result achieved without microbiome-disrupting active ingredients, in an Ecocert-certified and Made in France formula.

Building a Microbiome-Friendly Routine Step-by-Step
Caring for your microbiome doesn't mean overhauling your routine. It mostly means stopping its destruction — and choosing skincare that works with it, rather than against it.
Step 1 — Gentle cleansing (morning and evening)
This is the foundation of everything. An overly aggressive cleanser can destroy the microbial balance that took hours to rebuild in seconds. Opt for a foam with natural surfactants, rinsed with lukewarm water (never hot), which removes impurities without altering the hydrolipidic film.
3-in-1 Revitalizing Mask
Mask, exfoliant, and treatment in one step. Deeply revitalizes the microbiome thanks to floral active ingredients. 263 customer reviews ⭐

Step 2 — Active serum (evening)
In the evening, the skin enters an intense cellular regeneration phase. This is the ideal time to apply a serum concentrated with botanical active ingredients. The FLORACTIV20+® Anti-Aging Flower Capsule Serum delivers its active principles in a soothed microbial environment, maximizing their absorption and effectiveness.
Step 3 — Protective hydration (morning)
The Anti-Aging Floral Awakening Day Cream is formulated to create a protective barrier that maintains microbial balance throughout the day. Its light, non-occlusive texture allows the microbiome to "breathe" while protecting it from external aggressions.
Routine tip: Use the 3-in-1 Revitalizing Mask once or twice a week to renew and revitalize the skin's surface without disturbing the flora. Its revitalizing active ingredients ideally prepare the ground for your serum.
Signs of an Imbalanced Microbiome — and How to Act
Your skin talks to you. Certain signals, often interpreted as simple aesthetic problems, are actually symptoms of skin dysbiosis that need to be treated at the root.
Persistent redness, tightness after cleansing, recurring imperfections in the same areas, dull and grayish complexion, or feelings of discomfort after applying usual skincare are all alerts sent by the microbiome. Fortunately, with the right natural active ingredients and a respectful approach, balance can be restored in a few weeks.
The Lili Margo approach
The FLORACTIV20+® range was developed in France with a clear philosophy: formulas with 95-97% naturally derived ingredients, Ecocert certified, which nourish the skin and its microbiome without compromising clinical effectiveness. Made in France, transparent, and rated among the best by YUKA.

Frequently Asked Questions about the Skin Microbiome
What exactly is the skin microbiome?
The skin microbiome refers to all microorganisms living on the surface and in the superficial layers of the skin: bacteria, yeasts, fungi, and viruses. These microorganisms form a balanced ecosystem that protects the skin, regulates its pH, and strengthens its natural barrier. Each square centimeter of skin is home to approximately one million of them.
How do I know if my microbiome is imbalanced?
The main signs of an imbalanced microbiome are: persistent redness, tightness after cleansing, recurring imperfections, dull skin, discomfort after applying skincare, increased sensitivity to cold or heat. If you recognize several of these symptoms, your skin will benefit from a microbiome-friendly routine with gentle natural active ingredients.
Are natural products better for the microbiome?
Generally, yes. Formulas with a high content of natural ingredients (95-97% like Lili Margo) avoid chemical disruptors such as aggressive sulfates, parabens, or synthetic fragrances that can destabilize the skin flora. Botanical active ingredients also provide polyphenols and natural acids that nourish the protective flora like true prebiotics.
How long does it take to rebalance the skin microbiome?
With an adapted routine and skincare that respects the skin flora, the first results are generally seen in 2 to 4 weeks. The skin gradually regains its comfort, radiance, and tolerance to care. A lasting improvement in the microbiome is observed over 6 to 12 weeks of continuous routine with appropriate botanical active ingredients.
Does Lili Margo's FLORACTIV20+® complex act on the microbiome?
The patented FLORACTIV20+® complex is composed of 20 flowers selected for their complementary properties. These concentrated floral active ingredients provide a great diversity of polyphenols and biocompatible molecules with the skin flora. They act like natural prebiotics, nourishing the beneficial flora while strengthening the skin barrier. Clinically, the Floral Awakening Cream shows +23.4% collagen synthesis without disrupting the skin's ecosystem.
Can Lili Margo products be used on very sensitive skin?
Yes. The Lili Margo range has been formulated with particular attention to sensitive and reactive skin. Our products are free from major disruptive ingredients (sulfates, parabens, silicones, synthetic fragrances), Ecocert certified, and manufactured in France according to rigorous quality standards. The YUKA 100/100 rating of the Floral Awakening Cream attests to this demanding formulation.
