Nécessaire The Body Serum – Fragrance-Free Hyaluronic Acid Body Serum, 150 ml | Niacinamide Barrier Support, Fast-Absorbing

This lightweight 150 ml serum layers hydrating actives without sticky residue, offering multi-depth moisture using five molecular weights of hyaluronic acid alongside niacinamide. The formula was developed to be gentle — it’s free from fragrance, silicones, PEGs, parabens and phthalates, dermatologist-tested, and carries the National Eczema Association seal of acceptance. Use it daily to replenish and maintain skin hydration under creams or on its own.

How does this serum deliver lasting hydration?

The serum combines 0.5% hyaluronic acid delivered at five different molecular sizes to address hydration at multiple skin layers. Smaller molecules penetrate more deeply, while larger molecules sit closer to the surface to attract and hold water, creating both immediate and sustained moisture. Niacinamide supports the skin’s moisture barrier to reduce water loss over time.

• 0.5% hyaluronic acid across five molecular weights for multi-level hydration
• Niacinamide to help reinforce barrier function and moisture retention
• Light, fast-absorbing texture that layers under lotion or stands alone

Will this work for sensitive or eczema-prone skin?

Yes — the serum was formulated without common irritants and has been dermatologist-tested as hypoallergenic and non-comedogenic. It carries the National Eczema Association Seal of Acceptance, indicating review for suitability on reactive or eczema-prone skin. Still, patch testing is recommended for very reactive skin types.

• Fragrance-free and free from PEGs, parabens, silicones, and phthalates
• Dermatologist-tested and non-comedogenic
• Seal of Acceptance from the National Eczema Association

How should I use The Body Serum in my routine?

Apply to clean, slightly damp skin to maximize hyaluronic acid’s water-attracting benefits. It absorbs quickly, so you can apply it before a cream or oil, or use it solo if you prefer a lighter finish. Use morning and night or whenever skin feels dry; a little spreads a long way over large body areas.

• Apply to damp skin after showering for best absorption
• Layer under a body cream or oil for extra sealing of moisture
• Suitable for daily use on arms, legs, torso, and other dry areas

What’s in the formula and what’s left out?

The formula focuses on core hydration and barrier-supporting ingredients: hyaluronic acid at multiple molecular weights and niacinamide. It intentionally avoids known irritants to reduce the risk of sensitivity while remaining lightweight and non-greasy. Packaging and ingredient amounts are calibrated for effective body application without excess residue.

• Key actives: multi-weight hyaluronic acid (0.5%) and niacinamide
• Formulated without fragrance, PEGs, parabens, silicones, and phthalates
• Dermatologist-tested, hypoallergenic, and non-comedogenic

Who is this for? The Body Serum is designed for people who want targeted, non-sticky hydration for the body — especially those with dry, sensitive, or eczema-prone skin looking for a fragrance-free option. It’s a practical choice for anyone who prefers lightweight textures that layer easily with other body care products or need a daily step to help support their skin’s moisture barrier.
