localScale Changes the scale form the center and not the left

Hey everyone! So, I’m currently making a game and I’m at the part of adding a health bar to my character. Everything works! When an enemy hit me, I lose health! the only problem is that when ever I lose health the bar scales down to the middle and not from one end to the other like a normal health bar!

Here's the code that handle the scale of my health bar

     /// <summary>
     /// Mets à jour les divers éléments qui représente la vie du joueur.
     /// </summary>
     private void MettreAJourBarreVie()
     {
         // Normalise les points de vie.
         m_pointsVieNormalise = 1f * m_pointsVie / m_maxPointsVie;
 
         // Ajuste la barre selon les points de vie normalisés.
         m_barreVie.localScale = new Vector3(m_pointsVieNormalise, 1f, 1f);
         // Remplace le texte avec la nouvelle valeur.
         m_texteVie.text = $"{m_pointsVie} Go libres sur {m_maxPointsVie} Go";
     }
