Nécessaire The Body Serum is a lightweight, fragrance-free body serum with 0.5% multi-molecular hyaluronic acid and niacinamide designed to hydrate, absorb quickly, and support sensitive or eczema-prone skin.

This concentrated 50 ml formula combines five molecular weights of hyaluronic acid to replenish moisture at multiple layers of the skin while niacinamide helps support the skin’s moisture barrier. The fast-absorbing, non-sticky texture is formulated without fragrance, parabens, silicones, PEGs, or phthalates, and holds the National Eczema Association Seal of Acceptance. It’s presented in a compact bottle suited for daily body care routines and travel.

How does this serum hydrate dry or sensitive body skin?

The serum uses 0.5% pure multi-molecular hyaluronic acid to draw and lock in moisture across different skin layers, helping skin feel plumper and less tight. Its lightweight consistency allows rapid absorption so hydration is delivered without a greasy residue.

• Contains five molecular weights of hyaluronic acid for multi-depth hydration
• 0.5% concentration targets effective moisturization without heaviness
• Fast-absorbing texture leaves skin smooth, not sticky

Will this work for eczema-prone or reactive skin?

The formula is fragrance-free, dermatologist-tested, hypoallergenic, and non-comedogenic, which reduces the risk of irritation for reactive or sensitive skin. It’s also awarded the National Eczema Association Seal of Acceptance, indicating suitability for many people with eczema-prone skin.

• Fragrance-free and formulated without common irritants
• Dermatologist-tested and hypoallergenic for gentler use
• National Eczema Association Seal of Acceptance for eczema-prone skin

How does niacinamide help in a body serum?

Niacinamide supports the skin’s moisture barrier, which can help skin retain hydration delivered by hyaluronic acid and improve overall surface texture. In combination with multi-molecular hyaluronic acid, it contributes to more resilient-feeling skin over time.

• Supports the moisture barrier for longer-lasting hydration
• Helps improve skin texture and smoothness with consistent use
• Compatible with sensitive skin due to low-irritant formulation

How and when should I use The Body Serum in my routine?

Apply to clean, slightly damp skin to maximize hyaluronic acid’s moisture-attracting benefits, then follow with a cream or oil if extra occlusion is needed. Its lightweight formula makes it suitable for morning and evening use, and the 50 ml size is travel-friendly for on-the-go hydration.

• Use on damp skin for optimal absorption and moisture retention
• Layer under a body lotion or oil if you need added occlusion
• Suitable for daily use, morning and night, and travel-ready packaging
