Neutrogena Hydro Boost Waterproof Plumping Mascara — Black 0.21 oz, Hyaluronic Acid & Keratin for Hydrated Volume

Neutrogena Hydro Boost Waterproof Plumping Mascara is a hyaluronic-acid–enriched waterproof formula that builds visibly fuller, glossier lashes while resisting smudges and flakes.

Designed to hydrate as it defines, this mascara layers lightweight moisture and strengthening ingredients—hyaluronic acid, vitamin E, and keratin—onto each lash. The compact 0.21 oz tube and tapered brush help separate and coat lashes from root to tip for instant volume and a polished, natural black finish that lasts through daily wear.

How does this mascara plump lashes without feeling heavy?

The Hydro Boost formula deposits tiny amounts of hydrating hyaluronic acid and conditioning agents along the lash shaft, creating a fuller appearance without stiff buildup. Its lightweight emulsion balances moisture and hold, so lashes look thicker but still move naturally.

• Hyaluronic acid helps attract and retain moisture around lashes.
• Keratin and vitamin E provide conditioning and a smooth, glossy surface.
• Thin, buildable layers allow you to increase volume without clumping.

Will it survive sweat, humidity, and long days?

Yes—this is a waterproof, non-smudging and non-flaking mascara formulated to stay put through humidity and active days. It maintains lash definition while resisting melting or transfer, so touch-ups are rarely needed.

• Waterproof chemistry for reliable wear in heat or humidity.
• Designed to resist flaking for cleaner under-eye area.
• Ophthalmologist-tested and safe for contact lens wearers.

How do I apply and remove it for best results?

Use the tapered, lash-defining brush in outward strokes from root to tip to separate and coat each lash evenly. To avoid tugging during removal, dissolve the formula gently with an oil-based or dual-phase eye makeup remover and soft wipes.

• Apply 1–3 light coats, letting each dry slightly between layers for buildable volume.
• Wipe the wand on the tube rim to avoid excess product before application.
• Remove with Neutrogena Makeup Remover wipes or a gentle oil-based cleanser.

What shade and finish can I expect from the product?

The shade is a deep, true black that delivers glossy yet defined lashes without overpowering other eye makeup. The finish emphasizes thickness and shine rather than dramatic lengthening or stiff, spidery separation.

• True black pigment for everyday and evening looks.
• Glossy finish enhances perceived fullness and health.
• Best for natural-to-bold styles depending on layering.

Who is this for: ideal for anyone who wants a dependable, hydrating waterproof mascara that adds visible plumpness without flaking or stiff feel. It suits contact-lens wearers and people with dry or brittle lashes seeking conditioning benefits alongside long-lasting definition, whether you need a mascara for active days, humid climates, or polished daily wear.
