tarte Opening Act Lash Primer — White Conditioning Lash Base, Full Size with Vitamin C & 360° magniLASH Brush for Fuller, Longer-L

tarte Opening Act Lash Primer is a white-tinted lash base that primes, conditions and visually lengthens lashes while boosting mascara performance.

Apply Opening Act before mascara to create a lightweight, conditioning layer that helps lashes look fuller, thicker and more lifted. The white-tinted formula doubles as a lash treatment and primer, formulated without parabens, mineral oil, phthalates, triclosan, SLS or gluten. It uses a 360° magniLASH brush to coat each lash evenly, and contains plant-derived cellulose, carnauba wax, olive esters and vitamin C to support smooth application and a healthy-looking finish.

How does this primer improve my morning mascara routine?

Use Opening Act as the first step after curling lashes. The primer creates a base that mascara adheres to, which can amplify curl, volume and the perception of length without adding heavy flakes or clumps.

• 360° magniLASH brush evenly deposits product from root to tip
• white-tint visibly lengthens before mascara is applied
• lightweight texture prevents weighing lashes down
• designed to layer smoothly with most mascaras

Will this formula feel like a treatment or a cosmetic primer?

Opening Act is formulated to act as both: it primes lashes for makeup while delivering conditioning ingredients common to lash care. The result is a product that improves mascara performance and provides cosmetic nourishment without a heavy residue.

• plant-derived cellulose and carnauba wax for thicker-feeling finish
• olive esters to help condition lash fibers
• vitamin C included for antioxidant support in the formula
• vegan and ophthalmologist-tested for safety with contact lenses

How do I apply Opening Act for best results?

Begin with clean, dry lashes. Sweep the magniLASH brush from root to tip in a gentle zigzag motion to coat each lash. Allow a moment for the white tint to set, then follow with your favorite mascara to build desired volume and length.

• start at lash base and wiggle brush outward for even coverage
• apply one to two coats of primer before mascara, depending on preference
• pair with curling tools beforehand if extra lift is desired
• remove with regular makeup remover; gentle cleansing recommended

Is Opening Act suitable for sensitive eyes or contact lens wearers?

The formula has been ophthalmologist tested and is appropriate for contact lens wearers. It’s also dermatologist tested and formulated without common irritants like parabens, phthalates and sodium lauryl sulfate, making it a considerate choice for those who need gentler eye makeup options.

• ophthalmologist-tested for eye safety
• dermatologist-tested to minimize skin irritation
• free from parabens, mineral oil, phthalates, triclosan and gluten
• vegan and cruelty-free formulation

Who is this for: tarte Opening Act Lash Primer is aimed at anyone who wants a lightweight, multi-tasking lash base that improves the look of natural lashes and enhances mascara performance. It’s ideal for wearers seeking fuller-looking lashes without heavy formulas, people who wear contacts, and those who prefer products formulated without common irritants and animal-derived ingredients.
