The Tartelette formulas list conditioning and moisturizing ingredients such as shea butter and castor oil. Carnauba wax is also included to help provide a smooth application.

Instructions recommend two coats—apply a second coat quickly before the first dries to build a lash-extension effect. Reviewers also report achieving the desired look in two coats.

Tartelette formulas are stated to be free of parabens, mineral oil, phthalates, triclosan, sodium lauryl sulfate (SLS), and gluten. Some listings also note vegan and dermatologist-tested attributes.

Apply generously with the brush starting at the base of the lashes, then build by applying two consecutive upward coats—apply the second coat before the first dries for a lash-extension effect. To remove, soak a cotton pad with micellar water or makeup remover and gently massage the lashes to dissolve the formula.
