A lack of firmness in the neck manifests itself as follows:
Horizontal wrinkles (Venus's rings).
Vertical wrinkles at the neckline.
A slightly undefined chin.
Skin that isn't in the right place.
On this page, you'll find a specific approach—not to mask the symptoms, but to treat the underlying cause.
↳ The active ingredients reach the cells that produce the most protein. Once there, the proteins mature and become functional, helping to firm the skin.
A new technology
Tightening the skin is one of the most challenging goals. Modern dermatology is researching not only how to produce more collagen but also how to strengthen the connection between the dermis and the epidermis to prevent sagging.
The proteins responsible for both of these effects are produced by fibroblasts. However, newly produced proteins lack the strength needed to support the dermis. The body matures these proteins using specific enzymes so that they can reach their full strength.
We have developed a technology capable not only of increasing protein production but also of promoting protein maturation, thereby transforming a simple plumping effect into actual firmness.
The Cream: Biomimetic liquid crystals deliver protein fragments to the cells, where they trigger repair signals. The cells respond by increasing protein production.
Serum: facilitates the action of enzymes to mature newly synthesized proteins and make them functional.

What changes with use.
- Firmer, more supple skin. The primary effect, with maximum effectiveness.
- Ring-shaped lines on the neck and vertical wrinkles on the décolletage lose their depth at the same time.
- A more defined chin. A more sculpted profile.
When do you start to see results fr
? The first signs appear between the 2nd and 3rd week. Visible changes become apparent after 6–8 weeks. The improvement continues beyond that point: it’s a structural effect.
What it doesn't do
- It does not replace sunscreen, which remains essential for preventing the damage that causes the problem.
- The treatment reduces the deep signs of aging. Eliminating them usually requires medical treatment.
"Endor products are all about quality and effectiveness. The creams are amazing—they leave your skin smooth, moisturized, and looking beautiful."
Dr. Nuria Escoda.
"The serum firms the skin and reduces fine lines on the face, neck, and décolletage. Its formula delivers a highly effective anti-aging and restorative effect."

The treatment.
Suitable for all skin types.
AM / PM.
The serum and cream work perfectly well on their own. But when used together, they work in synergy to deliver optimal results.

The treatment targets the two biological pathways that enhance skin firmness: the production of structural proteins (Neck) and, once produced, their maturation to make them fully functional (Proteomic Serum).
Both products work perfectly well on their own. But when used together, they are most effective at addressing signs of sagging skin.

Our expertise in medical research provides us with the tools that, when applied to skincare, deliver results that surpass medical efficacy tests such as biopsies or ultrasounds—far exceeding those of cosmetic tests.

Directions for use.
- Morning and night.
- After cleansing your skin and letting it dry, apply the serum first. It has a light, fluid texture and spreads easily; you don't need much to cover your neck and the back of your neck.
- As soon as you finish applying it, you'll feel a slight tingling sensation on your skin. This is normal; the rheological network is forming to lock in moisture and give the active ingredients time to penetrate the skin.
- Once you notice that the serum has been absorbed and your skin feels dry but still slightly tight, apply the cream. Don’t wait more than 60–90 seconds between applying the serum and the cream.
- This treatment is not incompatible with any cosmetic products. However, we do not recommend mixing it with anything else. The formulas have been carefully designed to ensure that the active ingredients penetrate deep into the skin, and mixing them with other products may interfere with absorption.
Frequently Asked Questions.
This treatment is designed to minimize neck wrinkles and firm the area, resulting in a more defined and "well-defined" double chin.
It is suitable for all skin types.
If you have rosacea, dermatitis, acne or any other dermatological condition, it is advisable to consult your doctor before trying any cosmetic, this or any other.
For best results, use the cream both day and night. If you use a face mask at night, there’s no need to apply the treatment.
None of our products contain retinoids, so you can use them in combination with other products that do contain retinoids without worrying about exceeding the recommended maximum concentration of 0.3%.
However, our formulas are designed to help the active ingredients penetrate the skin, so we do not recommend combining them with other products. It is best to finish the products you are currently using and then start our treatment.
