tarte Opening Act Lash Primer – White Conditioning Mascara Base, Travel Size, Volumizing & Lengthening

tarte Opening Act Lash Primer is a white-tinted conditioning lash base that primes, strengthens and visually lengthens lashes before mascara.

This lightweight primer layers under your mascara to create a fuller, longer-looking lash line while helping lashes feel conditioned. The creamy white formula builds evenly with the 360° magniLASH brush, creating separation and lift so mascara grips and fans out more predictably. Formulated vegan and cruelty-free, it omits parabens, mineral oil, phthalates, triclosan, sodium lauryl sulfate and gluten.

How does this primer change my mascara routine?

Use the primer as the base step after any eyelash curler and before your chosen mascara. It creates texture and volume so mascara deposits more evenly and appears thicker without clumping.

• Apply one coat from root to tip with the 360° brush for even coverage.
• Let the white-tint set for a few seconds to add grip for mascara.
• Follow with your usual mascara to amplify length, curl and volume.

What active ingredients help condition lashes?

tarte’s formula blends plant-derived ingredients that smooth and support the lash surface while you layer product. These actives aim to leave lashes looking fuller and feeling conditioned rather than stiff.

• Cellulose: a plant-based thickening agent that adds body.
• Carnauba wax: promotes smooth application and volumizing effect.
• Olive esters & vitamin C: help condition and nourish lash fibers.
• Castor oil: commonly used to help lashes appear glossier and more pliable.

Is this safe for sensitive eyes and contact lens wearers?

The primer is ophthalmologist tested and safe for contact lens wearers according to clinical testing parameters. It’s also dermatologist tested and formulated without many common irritants, reducing risk for sensitive skin around the eyes.

• Ophthalmologist tested and contact lens friendly.
• Dermatologist tested and free of parabens and sulfates.
• Vegan and cruelty-free formulation.

How do I apply for maximum curl and volume?

For lifted, volumized lashes, begin at the base and wiggle the brush upward in a single even stroke to the tip. Allow the primer a moment to set, then layer your mascara using a combing motion to separate and define.

• Start at roots, sweep through to tips for even coating.
• Use multiple thin coats rather than one heavy layer to avoid stiffness.
• Pair with a volumizing or curling mascara for enhanced effect.

Who is this for: tarte Opening Act Lash Primer is for anyone who wants a conditioned, fuller-looking lash base before mascara—ideal for those with fine or sparse lashes, wearers of contact lenses, or anyone avoiding parabens and sulfates. It suits makeup lovers who want predictable mascara performance and an extra boost of lift and volume without harsh additives.
