Discover the new formula of PODERM® Ridged, broken nails Serum, enriched with plant-based keratin for enhanced strengthening action. *+23% increase in nail thickness in just 4 months! It strengthens, nourishes, and protects damaged nails and dry cuticles.
Keratin, the main protein in the nail, contributes to its strength and growth. It is essential for maintaining strong and healthy nails.
Thanks to the integration of phyto-keratin, our serum reinforces the naturally occurring keratin in the nail for stronger and more resilient nails.
Its formulation with natural Mimetix™ technology stimulates the production of essential molecules for nail health, helps prevent breakage, reduces ridges, and restores the protective barrier of both nails and cuticles.
The Ridged Nails Serum can be used in combination with the Color Strong range, which is rich in Silicon, Biotin, and Keratin, for amplified results.
The strengthening Color Strong care polishes are permeable to the serum, allowing nails to benefit from its properties even when applied over polish.
The result: continuously protected, nourished, and fortified nails.
*Clinical test conducted by an independent laboratory on [thickness / differentiation / cornification…] of the nail plate, 31 volunteers, [4/1] months.
Phyto-keratin offers a plant-based alternative to animal keratin, a natural component of the nail known for strengthening fragile nails.
Sweet orange peel essential oil is known for its gentle exfoliating action thanks to its fruit acid content.
Sweet almond is recognized for its nourishing and revitalizing properties, promoting smooth nail regrowth.

"Pour l'instant ça fait seulement 2 semaines d'utilisation du sérum, donc je ne peux pas dire que la cure soit concluante. Il faut certainement beaucoup plus de temps."
— Sylvie T. (3/5)
"En achetant ce sérum, je pensais que mes ongles deviendraient plus forts et plus épais comme mentionné sur le site. Cependant, après 3 semaines d'application journalière, je ne vois pas de changement, je suis un peu déçue mais je continue à l'utiliser le sérum jusqu'à la fin du flacon. Je ne pense pas recommander."
— Nadine L. (3/5)
"Trotz 2 mal täglich in den letzten 3 Wochen auftragen, habe ich gar keine Veränderung gemerkt. Leider. Die Nägel sind nach wie vor weich und reißen schnell ein. Ich hatte mir tatsächlich mehr erhofft, bei dem Öl für Kinder hatte ich das Gefühl, dass dies besser wirkt."
— Anna S. (3/5)
"J’avais des ongles striés et cassants depuis longtemps. Après une application quotidienne de ce sérum, la qualité et l’aspect de mes ongles se sont vraiment améliorés. Je recommande."
— VG38 (5/5)
"Leicht aufzutragen, angenehm auf den Nägeln eine Wirkung ist bereits zu spüren. Nur auf den Daumen ist es noch etwas hartnäckiger."
— Regine S. (5/5)
"il est efficace mais il n'y a pas de notice explicative. je pensais que ça s'appliquait comme un vernis mais pas du tout."
— ROUSSEL (3/5)
"Après avoir testé plusieurs marques, je me suis laissé tenter par celle-ci "Poderm". Sans regret à ce jour. Mes ongles sont plus beaux, plus fort chaque jour avec le sérum "ongles cassants striés". J'ai donc intégré à ma routine la Base Coat, le Color Care ou le Color Strong, le Top Coat et pour sublimer le tout, The sérum. Mes ongles ont retrouvés leur éclat digne d'un institut. Merci à l'équipe Poderm"

Our patented technology mimics natural defenses to restore healthy feet and nails.
This serum is recommended for strengthening nails and cuticles weakened by external aggression, nail ageing and the application of conventional, gel or semi-permanent nail varnish. The photos below illustrate the different uses of the serum:
Yes, it's perfect for nourishing and revitalising nails damaged by frequent manicures. Nails will regain their vitality and strength, and the product starts to work from the very first application.
PODERM® develops innovative formulations based on biomimicry. Designed to be in perfect affinity with the nail and skin, our formulas guarantee maximum compatibility and reduce the risk of allergic reactions. Our plants are grown without chemicals and distilled to obtain 100% pure and natural essential and vegetable oils. The manufacture of our products in Switzerland includes quality controls that comply with the most demanding standards.
The dry nail is fragile, sometimes sensitive, and can have an irregular appearance. It may break or split.
Here are some simple tips that can help care for brittle and weakened nails :
PODERM® nail serums do not offer UV protection due to their 100% natural serum-oil formulation. For UV protection, combine PODERM® Color Care and/or Color Strong nail polishes (excluding top coat, base coat, gloss vitality, and gloss éclat), which enhance the nail’s appearance and protect against UV rays while allowing you to continue your treatment (they do not need to be removed).
Poderm serums are not nail polishes, so they do not dry. They act on the nail and form a lipid film on the nail surface.
To accelerate absorption, we recommend gently massaging the serum into the nail and surrounding area for a few seconds.
Apply PODERM® Brittle and Ridged Nails Serum in the morning and/or evening to clean, healthy nails in sufficient quantity, paying special attention to the nail contours and grooves.
If you are using the Color Strong strengthening care polish, perform your manicure as usual first. Once the polish is applied, you can use the serum on top — its breathable formula penetrates through the polish to continuously nourish and strengthen the nails.
Yes, you can use our PODERM® Brittle and Ridged Nails Serum every day. Unlike other hardeners, it is not abrasive to the nail and is specially formulated for daily use. It gently nourishes and strengthens your nails without the risk of making them fragile. You can apply it morning and/or evening to help restore strong nails.
To strengthen soft nails, apply the PODERM® Brittle and Ridged Nails Serum daily, enriched with phyto-keratin. It will deeply nourish and harden your nails. Also, avoid prolonged exposure to water and chemicals to prevent weakening.
To make your nails stronger, you can use our Color Strong strengthening care nail polishes and our Brittle and Ridged Nails Serum. These polishes are specially designed to reinforce and protect nails while forming a protective layer. They are also permeable to the serum, allowing your nails to continue benefiting from nourishing and strengthening properties even under the polish.
Yes, it nourishes both the nail and its surrounding area, making it an excellent 2-in-1 alternative to cuticle oil. If you want to exfoliate dry cuticles, we recommend using it in combination with a cuticle emollient before your manicure.
