A plumping, smoothing serum that delivers visible firmness through hydration and film-forming ingredients — no aggressive actives required — built on the same fermentation base that runs through the whole line.

The Philosophy

Firmness and plumpness shouldn't require aggressive actives. This formula delivers an immediate, visible plumping and smoothing effect using hydration and film-forming ingredients, layered on the same fermentation base that runs through the rest of the line.

What It Does

  • Helps improve the appearance of fine lines and wrinkles
  • Helps improve skin elasticity and firmness (appearance-based effect)
  • Provides deep, long-lasting hydration
  • Improves skin texture for smoother, plumper-looking skin
  • Strengthens and supports the skin's moisture barrier
  • Protects and nourishes skin for a revitalized appearance

Key Ingredients

  • Galactomyces Ferment Filtrate — Fermentation-derived; radiance and texture improvement
  • Bifida Ferment Filtrate — Postbiotic; antioxidant, soothing, barrier support
  • Lactobacillus Ferment Lysate — Postbiotic; barrier and acid-mantle support
  • Collagen Extract — Forms a hydrating film that plumps and smooths skin's look and feel
  • 5-Type Hyaluronic Acid Complex — Layered hydration at multiple skin depths
  • Beta-Glucan — Soothing, hydrating, barrier support
  • Tocopheryl Acetate (Vitamin E) — Stable antioxidant; protects against oxidative stress
  • Tocopherol (Vitamin E) — Direct-acting antioxidant; protects skin cells and the formula

How to Use

Use in the evening, some nights, after cleansing and before your night cream. Apply a thin layer and allow to absorb before layering the next step.

How to use

How to build a probiotic skincare routine

Four steps, morning and evening. Always apply products from the lightest texture to the richest.

  1. Cleanse

    Massage the Probiotic Gentle Face Cleanser onto damp skin, then rinse. It removes dirt, oil and makeup without stripping.

  2. Treat

    Apply the Triple Vitamin C Serum to brighten, or the Wrinkle Treatment Serum to smooth the look of fine lines.

  3. Moisturize

    Follow with the Day and Night Moisturizer for lightweight, non-greasy hydration.

  4. Repair overnight

    In the evening, finish with the Probiotic Dream Night Cream so it can work while you sleep.
