Understanding the Science of Layering

Our skin's natural barrier is designed to retain moisture while keeping external aggressors at bay. Proper layering ensures that each product penetrates optimally and delivers its intended benefits. When applied correctly, lightweight, water-based products can hydrate the skin's deeper layers, while thicker, oil-based products lock in moisture and active ingredients.

Step-by-Step Skincare Layering

1. Start with Water-Based Serums
   Water-based serums contain humectants like hyaluronic acid, glycerin, and niacinamide, which draw water into the skin. Applying these serums first allows the skin to absorb hydration without the barrier of oils preventing penetration.
2. Follow with Emulsions or Lightweight Creams
   Next, apply emulsions or lightweight moisturizers that combine water and oil. These help seal in the hydration delivered by the serum while providing additional nourishment.
3. Finish with Oils or Oil-Based Serums
   Oils act as occlusives, forming a protective layer on the skin. This final step locks in all the moisture and active ingredients applied in the previous steps, preventing transepidermal water loss (TEWL) and maintaining skin elasticity.

Why This Technique Works

• Maximized Absorption: Water-based products can penetrate the skin effectively without interference from oil-based layers.
• Improved Hydration: Layering from lean to fat ensures deeper hydration and longer-lasting moisture retention.
• Barrier Support: Oils in the final step strengthen the skin's barrier, protecting against environmental stressors, while sealing all the moisture so it remains in the skin.

Applying the "fat over lean" principle to your skincare routine not only enhances product efficacy but also aligns with the natural structure of the skin, ensuring a balanced, hydrated, and resilient complexion.
