Nécessaire Body Serum — Fragrance-Free Hyaluronic + Niacinamide, Fast-Absorbing 150 ml

Nécessaire The Body Serum is a lightweight, fragrance-free hyaluronic acid body serum formulated with 0.5% multi-weight hyaluronic acid and niacinamide to hydrate, absorb quickly, and support dry, sensitive, or reactive skin.

This fast-absorbing body serum layers easily under lotions or can be used alone to replenish moisture where skin feels tight or parched. Designed for everyday use on the body, it pairs five molecular weights of hyaluronic acid with niacinamide to target hydration at multiple skin depths while remaining free of common irritants like fragrance, parabens, and silicones. The texture is non-sticky and non-greasy, making it practical for morning routines, layering under clothing, or evening skin-care rituals.

How does this serum hydrate without feeling heavy?

The formula uses 0.5% hyaluronic acid distributed across five molecular sizes to draw and bind water at different layers. That creates a layered hydration effect that feels light on the skin rather than coating it.

• Five molecular weights for surface and deeper hydration
• Lightweight, fast-absorbing texture that won’t leave residue
• Non-greasy finish suitable for daytime wear under clothes

Will it irritate sensitive or eczema-prone skin?

This serum is formulated without fragrance, PEGs, parabens, silicones, and phthalates and has been dermatologist-tested for tolerability. It carries the National Eczema Association Seal of Acceptance, indicating suitability for many sensitive or reactive skin types.

• Fragrance-free formula minimizes potential irritants
• Hypoallergenic and non-comedogenic for reduced clogging risk
• Dermatologist-tested and eczema-approved for sensitive skin use

How does niacinamide contribute to the product?

Niacinamide in the serum supports the skin’s moisture barrier and can help skin appear smoother and more even in texture. It works alongside hyaluronic acid to maintain hydrated, resilient body skin without adding oiliness.

• Supports barrier function to help retain moisture
• Helps refine skin texture while remaining lightweight
• Compatible with other body-care steps, including creams and oils

How should I use The Body Serum in my routine?

Apply to clean, slightly damp skin for best absorption, either all over or to targeted dry areas. Use alone for quick hydration or layer under your favorite body lotion or oil to lock in moisture.

• Pat onto damp skin immediately after showering for enhanced absorption
• Use daily—morning and/or evening—wherever skin needs hydration
• Layer under thicker creams for extra barrier support on very dry areas

Who is this for: The Body Serum is intended for anyone seeking lightweight, effective body hydration—especially people with dry, sensitive, or reactive skin types who prefer fragrance-free, dermatologist-tested formulations. It suits those who want fast-absorbing moisture that layers well with other products and avoids common irritants.
