The Countess is glowing.

Luann de Lesseps looks better than ever on her 12th season as one of the “Real Housewives of New York,” and the secret isn’t less fighting with Sonja Morgan about her cabaret show.

Instead, de Lesseps, 55, relies on the “survival kit” of skincare products she created with beauty company Sonäge, which she showed Page Six Style how she uses in the video above.

The brand derives its name from the French expression, “Bien porter son âge” — which translates to, “To look good for one’s age” — and boasts products approved by the Environmental Working Group for non-toxic ingredients.

Lu’s favorites include the Soothing Cleansing Crème ($28), Soothing Mist ($24), Botanica Soufflé Creme ($58) and more.

Skin as good as the Countess’ deserves its own stage — and never to be hidden in the lower level.
