  Formulated for Severely Dry, Lipid-Deficient, or Post-Procedure Skin

  Sérum T.E.W.L. delivers a replenishing boost of essential fatty acids to help repair the skin's hydrolipidic film and lock in moisture. It’s particularly effective for skin suffering from chronic dryness, sensitivity, or environmental aggression—such as wind, cold, or over-exfoliation.

  Key Benefits:

  • Reduces Water Loss: Reinforces the skin barrier to retain moisture longer.
  • Intense Nourishment: Provides immediate comfort to lipid-depleted skin.
  • Restores Barrier Function: Helps repair skin weakened by harsh conditions or treatments.
  • Protects Against External Aggressors: Shields from wind, cold, and pollution.
  • Ideal for Crisis Care: Perfect as a rescue serum for extreme dryness and flaking.

  Why Choose Sérum T.E.W.L.?

  Unlike water-based serums, Sérum T.E.W.L. is oil-rich and specifically designed to treat lipid deficiency and water evaporation. It’s a go-to for skin that needs deep, structural repair and replenishment.

• How to Use:

  • Step 1: Apply in the evening after your serum and cream, or use it alone on very dry skin.
  • Step 2: Massage a few drops into the face, neck, and décolleté until fully absorbed.
  • Step 3: For best results, use as a treatment during cold weather, after peels, or whenever the skin barrier is compromised.

  Not suitable for acne-prone or oily skin types.

• Key Ingredients:

  • Raspberry Seed Oil: Rich in omega-3 and omega-6 to repair and nourish.
  • Cottonseed Oil: Softens and smooths while supporting lipid balance.
  • Hazelnut Oil: Helps strengthen skin structure and prevent moisture loss.
  • Antioxidants: Protect against free radical damage and environmental stress.

• What to Expect:

  Skin feels immediately soothed, replenished, and protected. With regular use, roughness, tightness, and flaking are significantly reduced. The complexion regains its softness, suppleness, and resilience—especially in harsh or drying environments.
