Neutrogena Hydro Boost Waterproof Plumping Mascara, Black 0.21 oz — Hyaluronic Acid, Long-Wear

Neutrogena Hydro Boost Waterproof Plumping Mascara is a hyaluronic-acid-enriched, waterproof mascara that coats lashes for an instantly plumper, glossy, long-wear finish without smudging or flaking.

This waterproof plumping mascara blends hyaluronic acid, vitamin E and keratin into a nourishing formula designed to hydrate brittle lashes while adding visible volume and length. The formula is ophthalmologist-tested and safe for contact lens wearers, and the conical lash-defining brush helps separate and lift each lash for an even, fuller look. Lightweight yet buildable, the black shade gives a dramatic finish while resisting smears throughout the day.

How does this mascara make lashes look plumper and longer?

The formula contains hyaluronic acid to attract and retain moisture at the lash surface, plus keratin and vitamin E to help coat and smooth each fiber. Together these ingredients produce a glossy, thicker appearance without stiff or gummy buildup. The conical brush deposits pigment at the base and tip for instant lift and visible length.

• Hyaluronic acid hydrates and adds surface volume
• Keratin and vitamin E smooth and coat lashes for shine
• Conical brush builds base-to-tip thickness and lift
• Black pigment enhances contrast and perceived length

Will it stay put during humid days or workouts?

This product is formulated as waterproof and non-smudging, created to resist running and flaking when exposed to humidity or perspiration. It maintains lash definition through daily activities, though removal should use a suitable makeup remover to fully dissolve the formula. Because it’s waterproof, regular gentle cleansing is recommended to avoid rubbing.

• Waterproof formula resists smears and flaking
• Holds curl and definition in humid conditions
• Removes cleanly with oil-based or Neutrogena makeup remover

How do I apply and remove it for best results?

Apply with outward strokes using the conical brush to catch inner and outer corner lashes; build in thin layers for more volume without clumping. For removal, soak a cotton pad with an oil-based remover or micellar cleanser, hold over closed eyes briefly, then wipe gently to dissolve waterproof pigment. Avoid aggressive rubbing to protect delicate lashes.

• Swipe wand outward from base to tip for lift
• Layer lightly for buildable volume without clumps
• Use oil-based or Neutrogena remover for gentle dissolution

Is this mascara safe for sensitive eyes and contact lens wearers?

The mascara is ophthalmologist-tested and formulated to minimize irritation, making it suitable for many people who wear contacts or have sensitive eyes. As with any eye cosmetic, discontinue use if irritation occurs and consult a professional if you have ongoing sensitivity. The gentle hydration elements aim to soothe rather than dry lashes.

• Ophthalmologist-tested formulation
• Designed to be safe for contact lens wearers
• Contains conditioning agents to help reduce brittleness

Who is this for: This mascara suits anyone wanting visibly fuller, glossier lashes that withstand humidity, workouts, or long days—especially those with dry or brittle lashes who want hydration plus dramatic definition. It’s a good pick for contact lens wearers and shoppers seeking a waterproof, buildable mascara with conditioning actives like hyaluronic acid, vitamin E, and keratin.
