LAYERLAB Barrier Boost Serum — 5% Panthenol, 4% Niacinamide, 50ml lightweight calming hydration with nano-ceramides

LAYERLAB Barrier Boost Serum is a lightweight Korean serum that combines 5% dexpanthenol and 4% niacinamide to hydrate, calm, and strengthen sensitive skin.

This concentrated 50ml serum blends targeted actives with advanced delivery technology and mineral-rich volcanic water to support a healthier-looking moisture barrier and a dewy, refined surface. Formulated for sensitive and reactive skin, the formula emphasizes absorption and long-lasting hydration without heaviness or pilling beneath other products.

How does the serum calm and hydrate sensitive skin?

The formula pairs a high dose of dexpanthenol (5%) with niacinamide (4%) to provide multi-layered hydration and visible soothing. These actives help the skin feel less reactive while enhancing surface moisture and comfort.

• 5% dexpanthenol to help maintain moisture retention and comfort
• 4% niacinamide to support even texture and tone
• Light, non-greasy texture that sinks in quickly

What makes the delivery system more effective than regular serums?

LAYERLAB uses nano-ceramide technology to reduce ceramide particles to a smaller size, helping them penetrate more easily into the top layers of skin. This helps support the skin’s natural barrier and increases the serum’s overall hydration impact.

• Nano-ceramides for improved absorption into the skin surface
• Niosome-encapsulation for stable, targeted delivery of actives
• Clinically tested delivery to support visible barrier comfort

Why is volcanic water included, and what does it do?

Instead of regular purified water, this serum uses 44.6% mineral-rich volcanic rock water from New Zealand to add essential minerals that help condition and hydrate skin. The minerals contribute to a fresh-feeling base that complements the active ingredients.

• 44.6% volcanic rock water supplies trace minerals for skin conditioning
• Supports a hydrated, dewy finish without heaviness
• Enhances overall skin radiance and texture when layered under moisturizers

Will it work under makeup and in a daily routine?

The serum is formulated to absorb cleanly and create a smooth canvas without pilling, so it layers well under SPF and foundation. Its lightweight, band-like texture helps lock in moisture while keeping skin comfortable throughout the day.

• Fast-absorbing formula that won’t pill under cosmetics
• Use morning and evening after cleansing and before moisturizer
• Suitable as a base step for sensitive skin routines

Who is this for: LAYERLAB Barrier Boost Serum is designed for people with sensitive, dehydrated, or easily reactive skin who want a high-potency, fast-absorbing treatment to support the skin’s moisture barrier. It’s also a good choice for anyone seeking a lightweight, clinically-informed Korean serum to smooth texture and enhance a natural, hydrated glow without heavy oils or sticky residues.
