Give your skin the moisture it deserves. Hyaluronic acid is a molecule naturally found in our bodies that can hold up to 1,000 times its weight in water, providing all-day hydration for your skin. The significant amount of matcha in our serum helps to reduce inflammation and firm the skin.
Additionally, mandarin is rich in vitamins A and C and is known for stimulating the production of natural collagen, which helps reduce the appearance of expression lines.

A big WOW 🤩 This product is AMAZING! After just one use, I could already see the results. I’m so satisfied!
I love it!!!!! Super effective and I’m already seeing an improvement. My skin feels smoother and the scent is lovely. I highly recommend it!
I discovered O’terra just a few weeks ago, and it’s truly love at first sight! This cream is amazing — it deeply hydrates and softens the skin, and it’s perfect for preventing stretch marks, especially during weight loss. A real gem!

Très confortable
Si rafraîchissant Je l’idée. Comme tout vos produits d’ailleurs
Good
Le celluskin est le traitement idéal pour traiter
La cellulite qui est incrusté il déloge les capitons!Pratiquement pas de douleur de mon côté!
Je suis une cliente fidèle du Celluskin et le Kuma.
Efficace même pour peau mature!
Excellent goût!
J’adore! La texture qu’elle donne à ma peau et que dire de son odeur très agréable!
J’ai vu une différence rapidement. Mes cuisses sont plus lisses. C’est quand meme impressionnant.
J’adore l’odeur la texture de l’huile…le baume à lèvre aussi ;-)
Les chaussons utilisés avec le beurre soyeux rendent les pieds vraiment doux.
C'est un petit outil précieux. Facile à utiliser et efficace. On voit une légère amélioration dès le premier usage. Je l'utilise 1 x semaine avec le sérum. Je le recommande.
Extra! Jambes légères assurées après.
J'ai eu recours à ce soin avant d'entamer le Kuma et non seulement j'en ressortais les jambes plus légères et désengorgées, mais cetait un moment de pure détente ! C'est relaxant et bénéfique ce traitement.
J'utilise la roulette depuis quelques années et je sens mes jambes moins lourdes et désengorgées. Ce traitement se fait tout en regardant son émission préférée. 😉
L'odeur de ce baume à lèvres fait rêver et il hydrate à la perfection ! Un immense coup de coeur.
