LAYERLAB Barrier Boost Serum — 5% Panthenol & 4% Niacinamide, 30ml Lightweight Soothing Hydration

LAYERLAB Barrier Boost Serum is a high-potency Korean soothing serum formulated with 5% dexpanthenol and 4% niacinamide to hydrate, calm, and help reinforce the skin's moisture barrier.

This lightweight 30 ml serum combines concentrated active ingredients with advanced delivery technology and mineral-rich volcanic rock water to target sensitivity and dryness without heaviness. Designed for layered skincare routines, it absorbs quickly and leaves a luminous, glass-like finish that works under makeup. Clinical testing and customer repeat-purchase data support its reputation as a calming, everyday booster that integrates easily into morning or evening regimens.

How does this serum soothe sensitive or irritated skin?

The formula centers on 5% dexpanthenol (a pro-vitamin B5) which helps attract and retain moisture while supporting visible comfort. Niacinamide at 4% complements that action by promoting a smoother skin texture and helping skin appear less reactive. Together they provide concentrated hydration and visible calming effects without a heavy residue.

• 5% dexpanthenol for moisture retention and surface soothing
• 4% niacinamide to refine texture and tone
• Fast-absorbing, non-greasy serum base suitable for layered routines

What makes the delivery and ingredients effective?

LAYERLAB uses nano-ceramide technology to break ceramides into smaller particles for enhanced penetration, helping actives reach deeper layers more efficiently. Instead of plain water, the serum is built with 44.6% volcanic rock water rich in trace minerals, which supports natural hydration and a healthy-looking glow. The overall texture is designed to sit smoothly on skin, avoiding pilling under creams or makeup.

• Nano-ceramides for improved absorption and barrier support
• 44.6% mineral-rich volcanic rock water for added hydration
• Hydrating band-like texture that layers well with other products

Will this serum suit my morning or evening routine?

This serum is formulated to be versatile: it hydrates and calms (making it ideal for morning use under sunscreen or makeup) while also supporting repair and replenishment overnight. Because it absorbs quickly and doesn't leave a heavy film, it can be used both before creams and after lighter essences. Users reported improved comfort and a radiant finish when incorporated consistently.

• Use in the morning before moisturizer and SPF for a smooth base
• Layer at night under richer creams to support barrier recovery
• Compatible with most actives—introduce gradually if using strong exfoliants

How is product performance validated and what can customers expect?

The serum’s formulation and effects have been evaluated through clinical testing and customer response milestones. Independent studies and user feedback indicate noticeable improvements in calmness and hydration after short-term use, and many customers choose to repurchase within weeks. Expect a hydrated, less reactive appearance and a dewy, glass-skin–style finish when used consistently.

• Multiple clinical tests backing calming and hydration claims
• High repurchase rate reflecting repeat user satisfaction
• Light-reflecting finish for a radiant, healthy look

Who is this for? LAYERLAB Barrier Boost Serum is aimed at people with sensitive, dehydrated, or reactive skin who want a concentrated, fast-absorbing booster that calms and hydrates without heaviness. It's also suitable for those building a Korean-style layered routine, anyone seeking to reinforce their moisture barrier, and users wanting a serum that plays well under makeup and other skincare steps.
