Collagen and snail slime: a precious duo for healthy skin
With age, our skin loses its youthfulness: it becomes thinner, less elastic, and wrinkles appear. This phenomenon is mainly due to the progressive decrease in collagen and elastin, two proteins essential for skin suppleness and firmness. At Mademoiselle Agathe, we have made organic snail slime our flagship ingredient, not only for its restorative properties, but especially for its scientifically proven ability to stimulate the synthesis of type I and III collagen, as well as elastin (Adikwu et al., 2008). A powerful asset in the fight against skin aging.
Collagen and elastin: pillars of skin youth
Collagen and elastin are the main components of the dermal matrix. While collagen provides structure and density to the skin, elastin gives it its ability to stretch and relax without deforming. Unfortunately, from the age of 25, their production begins to slow, leading to sagging, wrinkles, and a loss of radiance.
Unlike conventional skincare products that only work on the surface, Mademoiselle Agathe's organic snail slime formulas work deep down, naturally stimulating the production of these structural proteins. It's a biomimetic approach that respects skin physiology and encourages the skin to regenerate on its own.

- Organic Lavender Soap offers soothing and balancing care. With its fresh lavender scent and cold saponification, it purifies and hydrates the skin without unbalancing it, providing a feeling of softness and comfort.
- Organic Mint Soap offers a feeling of freshness and tone. This soap combines snail slime and mint essential oil. It brings this wonderful toning and invigorating sensation so sought after in summer. And offers your body a pleasant minty freshness on the skin.
Snail slime: a natural collagen booster
According to the study by Adikwu et al. (2008), the proteins present in snail slime actively stimulate the synthesis of collagen types I and III as well as that of elastin. These effects directly contribute to delaying skin aging, by strengthening the dermal structure and accelerating cell renewal. This is the mechanism that we exploit in our highly concentrated anti-aging facial serum in snail slime and our regenerating facial day cream.
Our treatments work on two levels: on the surface to smooth and hydrate, and deep down to rebuild the skin's foundations, with proven effectiveness on expression lines, fine lines and loss of firmness.




How to integrate collagen into your beauty routine?
Firm, plump skin requires continuous stimulation of its natural proteins. For this, we recommend a complete routine, consisting of our Helicitherapy treatments.
- Micellar water: gently cleanses, while preparing the skin to receive the active ingredients.
- Eye contour serum: fights signs of fatigue and aging
- Anti-aging facial serum: promotes cell regeneration and stimulates collagen production.
- Anti-aging face cream: hydrates, protects and improves skin density thanks to its richness in natural vitamins.
Visible and lasting results on skin firmness
The effects of snail slime treatments are immediate. Within the first few weeks, skin is smoother, more toned, and better hydrated. With continued use, wrinkles fade, skin texture becomes denser, and the complexion regains its natural radiance.
Thanks to the combined action of allantoin, vitamins, glycolic acid and the stimulating proteins of snail slime, the skin regains its ability to regenerate by itself: a healthier and more sustainable approach to anti-aging.


At Mademoiselle Agathe, we believe that the best cosmetic technology is that which nature has already invented. Organic snail slime, with its ability to stimulate the natural production of collagen and elastin, offers an effective, gentle, and environmentally friendly anti-aging solution for both skin and the environment.
By incorporating our Helicitherapy treatments into your beauty routine, you're choosing an organic, innovative, and committed cosmetic that can naturally slow the signs of aging. Rediscover firm, supple, and radiant skin.
