The anti-wrinkle skincare that goes where others stop.

It depends on where the problem is concentrated.

If the wrinkles are on your face —eye contour, forehead, expression lines— the starting point is the Silk Peptide Serum. The Golden Silk Matrix™ works in the first 0.02 mm, where expression wrinkles form, exactly where no classic cream can reach.

If the main problem is your neck —sagging skin, horizontal lines, loss of firmness— the choice is between the two Neck Firming Creams. If you want the pure active treatment, choose the Neck Firming Cream with Matribust®. If you want a dual mechanical and active action, choose the Neck Firming Cream with Roller.

Many customers use all three together: the serum for the face, the neck cream as a dedicated treatment.

Skin has a natural shield —the Stratum Corneum— that blocks almost everything you apply to the surface. Retinol, hyaluronic acid, classic peptides: they get that far and stop.

The Silk Peptides in the Golden Silk Matrix™ have a molecular structure small enough to get through it. Once inside, they interlace to form a protein micro-mesh that supports the skin exactly where it has creased. Acetyl Hexapeptide-8 gradually reduces the intensity of the muscle contractions that deepen expression wrinkles. The result is structure, not surface hydration.

Because it has a different internal structure.

Beneath the skin of the neck there's an invisible support network —the dermal-epidermal junction— that keeps the two layers of skin anchored together.

Over time that network comes loose and the skin loses the internal support that kept it taut.

That's why face creams, even the best ones, don't work on the neck: they aren't formulated to act on that specific structure.

Both contain Matribust® (patented by SILAB, 2.5%), the active that works directly on the dermal-epidermal junction to reconnect the two layers of skin that have separated.

The difference is in how it's applied. The Neck Firming Cream with Roller adds a physical first step: the roller mechanically relaxes the tissue before the actives penetrate. It's not an optional accessory; it's the essential first step.

On already relaxed tissue, Acetyl Hexapeptide-8 penetrates more effectively and reduces the contraction of the platysma muscle, which contributes to vertical neck bands.

If you want the essential treatment, choose the Neck Firming Cream. If you want the dual mechanical and active action, choose the Roller Kit.

Yes, and it's the combination we recommend.

The two products work on different areas with complementary mechanisms, without overlapping. The Serum treats the face (down to the chin area); the Neck Firming Cream goes from the jawline down, with a formula specific to the structure of the neck.

They don't get in each other's way: they complete each other.

The ideal routine is to apply the Serum to your face first, then the Neck Firming Cream to its dedicated area.

You can try it risk-free. If you're not happy with the results, you can claim our 99-day satisfaction-or-refund guarantee, which includes a full refund.

Fewer than 1% asked for a refund, which shows how effective the products are.

It depends on the product and the area treated.

With the Serum, many customers notice a perceptible tightening effect within the first few weeks. The most visible changes appear between the fourth and sixth week of consistent use.

With the Neck Firming Creams, results on the structure of the neck take a little longer: the area is more complex and the dermal-epidermal junction reorganizes gradually. The first differences show around the sixth week; the most significant transformation, between 60 and 90 days.

That's why the guarantee on all Sedanza products lasts 99 days: you want the time you need to see the full difference before deciding.

Yes, and they were developed specifically for that profile. Mature skin has already been through years of harsh routines, often with irritating ingredients like high-concentration retinol or chemical peels.

Sedanza formulas contain no fragrances, artificial colorants or agents known to irritate sensitive skin.

All products are dermatologically tested.

If you have a specific skin condition or are undergoing dermatological treatment, we recommend checking with your doctor before using them.

Sedanza products are developed in compliance with European cosmetic regulations, among the strictest in the world, and are Cruelty Free and Vegan. The formulas are made following high quality standards and safety checks, and are designed for daily use, even on sensitive skin.

For transparency, we don't advertise superfluous or misleading certifications: we prefer to focus on selected ingredients, tolerance and visible results. The full ingredient list (INCI) is always available in the dedicated section of each product page.
