Discover the secret to firmer, smoother skin
From the most surprising corners of nature comes a revolutionary biomimetic peptide that smooths out expression lines, softens facial features, and provides a lifting effect.
Who would have thought that one of the most fascinating anti-aging discoveries could come from the depths of the oceans? Among the wonders of modern biotechnology, one peptide stands out, inspired by a marine creature as mysterious as it is powerful: the Conus consors, a predatory mollusk capable of immobilizing its prey with a complex cocktail of natural peptides.

Cosmetic science has drawn inspiration from this natural mechanism, creating a safe, sustainable, and cruelty-free version: S-Mu-Conotoxin CnIIIC Acetate, a biomimetic peptide that selectively replicates the muscle-relaxing action of certain marine toxins, without side effects, toxicity, or invasive procedures.
How does S-Mu-Conotoxin actually work?
S-Mu-Conotoxin CnIIIC Acetate is a next-generation biomimetic peptide, structured to rapidly penetrate the skin and selectively block the channels located at the neuromuscular junction. It inhibits muscle fiber contraction, reducing the formation of expression lines. It begins to work within 2 hours of application, with visible results and progressive improvement over time (cumulative effect at 28 days). It represents an effective and non-invasive cosmetic alternative to botulinum toxin, with a skin-relaxing and smoothing effect.

This peptide does not paralyze the muscles like Botox, but gently relaxes them, reducing involuntary contractions and softening expression lines, forehead creases, and lines around the eyes and nasolabial folds. All this is achieved through a gentle, “soft-touch” approach that respects the skin’s natural balance and is suitable for all skin types.
Why is it compared to Botox?
The association with Botox stems from the visible results: a relaxed, smooth, and lifted complexion. But S-Mu-Conotoxin offers something more: it acts deeply, also stimulating the production of new collagen—a characteristic that makes it not only corrective but also regenerative.
This peptide is not derived from animals but is synthesized in a laboratory, mimicking the structure and function of natural toxins in an ethical and safe manner.

This precious ingredient is a true ally against the effects of aging. Its multi-level action:
-
It relaxes the superficial muscle contractions responsible for expression lines. It acts quickly and visibly, reducing wrinkles as early as 2 hours after application (-9.5% in the depth of crow’s feet). It has long-lasting effectiveness, relaxing muscles for up to 24 hours.
-
Visibly smooths and firms the skin from the very first applications. It provides a daily lifting effect, improves skin smoothness, opens up the eyes, and reduces the appearance of a tired face.
-
It stimulates collagen production, improving skin tone over the long term.
-
It improves hydration, making the skin softer and more radiant.
-
It is well tolerated even by sensitive skin. With a high level of dermatological safety, it is hypoallergenic, non-irritating, and non-sensitizing, thanks to its preservative-free formula


In the N|Skin by Napura line, S-Mu-Conotoxin CnIIIC is combined with other highly effective functional peptides, such as Palmitoyl Tripeptide-5 and Palmitoyl Dipeptide-5, for a comprehensive effect:
-
Deep
firming
-
Correction of static and dynamic
wrinkles
-
Smooth, toned, and youthful
skin
All enriched with moisturizing active ingredients such as Vegetable Glycerol to enhance absorption and keep the skin protected and nourished.
Here are all the products in the Firm Line that contain this biomimetic peptide:

-
Instant Filler, a smoothing, anti-wrinkle eye contour plasma—an intensive beauty treatment formulated to visibly reduce the signs of aging, improve firmness, and reveal a rested, relaxed appearance.
- Beauty Prep, a hydrating, lifting facial toner—an advanced facial preparer that combines intense hydration with a lifting effect, ideal for preparing the skin to receive subsequent treatments.
- Lift Booster, a peptide-based facial serum specifically designed to provide a firming and rejuvenating effect. Its advanced formula combines high-quality ingredients that work in synergy to visibly improve skin elasticity, reducing wrinkles and fine lines for a youthful and radiant appearance.
- Ageless Potion, an anti-wrinkle day cream formulated to effectively combat the signs of skin aging, restoring firmness, tone, and deep hydration to the skin.
- Dreamy Repair, an anti-wrinkle night cream, is designed to combat the signs of aging while you sleep—when the skin is most receptive to regenerative treatments.
Forget the idea that invasive or painful treatments are needed to look younger. The new frontier in skincare is bio-intelligent cosmetics, capable of listening to the body’s language and responding with precision.
A biomometric peptide like S-Mu-Conotoxin CnIIIC Acetate epitomizes this evolution: a molecule that combines science, ethics, and performance. The result? Skin that radiates well-being, care, and vitality, without altering your natural beauty.
