Nécessaire Body Serum — Fragrance-Free Hyaluronic Acid Body Serum, 50 ml, Fast-Absorbing & Non-Greasy

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

This lightweight 50 ml/1.7 fl oz serum delivers layered hydration using five molecular weights of hyaluronic acid to attract and hold moisture at different levels of the skin. The formula is fragrance-free, dermatologist-tested, non-comedogenic and carries the National Eczema Association Seal of Acceptance, making it suitable for anyone seeking intensive, non-greasy moisture without common irritants. Fast-absorbing and formulated without PEGs, parabens, silicones or phthalates, it works as a standalone hydrator or added step in your body-care routine.

How does this serum hydrate dry or eczema-prone skin?

The serum uses 0.5% pure hyaluronic acid presented in five molecular weights so moisture is drawn and retained at multiple skin layers, from surface smoothing to deeper-level plumping. Niacinamide supports the skin’s moisture barrier, helping skin feel softer and look smoother without irritation.

• 0.5% multi-molecular hyaluronic acid for staggered hydration
• Niacinamide to help maintain barrier function
• Lightweight texture absorbs quickly—no sticky residue
• Eczema-approved and dermatologist-tested for sensitive skin

Will this feel heavy or leave a greasy layer on my skin?

No—The Body Serum is formulated to be fast-absorbing and non-greasy. Its thin, serum-like consistency sinks in quickly, making it suitable for morning routines or layering under thicker creams where additional occlusion is desired.

• Non-sticky finish suitable for daytime wear
• Works well under lotion or body oil if extra sealing is needed
• Quick absorption allows immediate dressing after application

Is this product safe for sensitive, reactive or acne-prone body skin?

The formula avoids common irritants like fragrance, parabens, silicones and phthalates, and is labeled hypoallergenic and non-comedogenic. It has been tested by dermatologists and accepted by the National Eczema Association, though patch testing is recommended for those with very reactive skin.

• Fragrance-free and formulated without known irritants
• Dermatologist-tested and non-comedogenic
• National Eczema Association Seal of Acceptance

How should I incorporate this into my body-care routine?

Use The Body Serum after showering while skin is slightly damp to lock in moisture, or apply between lighter and heavier layers—serum first, then cream or oil if you need extra occlusion. A small amount covers targeted areas or larger surface areas when smoothed evenly.

• Apply to damp skin for best hydration retention
• Use alone for a lightweight finish or under a moisturizer for added sealing
• Ideal for daily use on arms, legs, chest and dry patches

Who is this for: The Body Serum is aimed at anyone looking for a concentrated, non-greasy hydrator—especially people with dry, sensitive or eczema-prone skin who prefer fragrance-free, dermatologist-tested products.
