Can a natural product be as effective as a chemical treatment? Proof from Demain Beauty
For a long time, the world of cosmetics has opposed effectiveness and naturalness.
On the one hand, conventional products, often loaded with synthetic ingredients, promise quick results.
On the other hand, natural treatments are perceived as less effective.
Today, this preconceived idea is outdated: thanks to scientific advances and green biotechnologies, 100% natural care products can offer results equivalent to, or even superior to, those of chemical products, while respecting the skin and the planet.
At Demain Beauty, this vision is at the heart of each formula: organic, clean care, enriched with objective active ingredients, clinically tested, without compromising on effectiveness.
Natural vs. chemical: scientifically comparable effectiveness
The effectiveness of a treatment does not depend solely on the natural or synthetic origin of an active ingredient, but on its quality, concentration, bioavailability and, above all, its synergy with other ingredients.
Today, numerous clinical studies demonstrate the proven effectiveness of natural products , just like molecules derived from conventional chemistry.

Natural active ingredients with clinically proven effectiveness
Demain Beauty formulas are based on powerful and objective active ingredients, i.e. evaluated by independent scientific studies, to guarantee measurable results on the skin.
Hydrolyzed marine collagen: as effective as chemical alternatives
Collagen makes up about 30 to 35% of the protein in the human body. It is essential for the structure of skin, hair, nails, and connective tissue. Its production declines from the age of 25, leading to loss of firmness and wrinkles.
The effectiveness of hydrolyzed marine collagen types I and II has been widely demonstrated. One study shows that supplementing with marine collagen peptides improves skin elasticity, hydration, and density in just 8 weeks.
In Age With Grace by Demain®, this marine-sourced collagen is combined with vitamin C, essential for its natural synthesis in the body.
Vitamin C: a natural efficiency booster
L-ascorbic acid (vitamin C) is much more than just an antioxidant: it plays a central role in the production of endogenous collagen and the protection of skin cells against premature aging.
Its effectiveness has been demonstrated in numerous clinical studies, and its association with collagen as a food supplement helps to amplify the results on the skin.
Natural hyaluronic acid: hydration, smoothing, plumping
Hyaluronic acid, naturally present in the dermis, retains up to 1000 times its weight in water, and contributes to skin rebound. The version used in Age With Grace (in the form of sodium hyaluronate) is 100% natural, with excellent bioavailability.
Skin prebiotics and probiotics: a gentle and effective revolution
Demain® cosmetic treatments are enriched with prebiotics and probiotics, true natural regulators of the skin microbiome. These natural active ingredients promote the balance of the skin flora, limit imperfections and strengthen the skin's protective barrier.
A scientific review published in the Journal of Drugs in Dermatology confirms the visible effects of topical probiotics on acne-prone, atopic or sensitive skin, with results comparable to those of certain conventional molecules ( Knackstedt et al., 2020 – NCBI ).
Digestive prebiotics: chicory inulin to boost assimilation
In the Inside/Out approach of Demain Beauty, the effectiveness of supplements also depends on digestion and assimilation.
That's why Age With Grace also contains chicory inulin, a natural prebiotic that promotes the balance of the intestinal microbiota and optimizes nutrient absorption.
And what about conventional products?
Certainly, synthetic molecules like retinoids or exfoliating acids can be effective... but often at the cost of significant side effects: irritation, peeling, hyperreactivity.
A scientific review on retinoids highlights their effectiveness but also their low skin tolerance ( Mukherjee et al., 2006 – NCBI ).
Conversely, well-formulated natural skincare products like those from Demain® offer visible results without damaging the skin, even sensitive skin.

Sensoriality: an efficiency criterion too often forgotten
Effectiveness is not only measured by clinical results: it also involves the pleasure of use.
This is where Demain Beauty stands out again, with fine, melting textures, natural fragrances and sensory application.
Treatments that are good for the skin, but also for yourself.

The overall effectiveness of natural products: skin, well-being, planet
Effective care also means healthy, clean, and long-lasting care.
