Waterproof Smudgeproof Lengthening Mascara with Thin Brush Black Clear benefits Creates visible length and definition without clumping. The thin brush separates lashes while coating each hair for a natural yet extended look. Waterproof and smudgeproof formula helps lashes stay clean and defined through humidity, light perspiration, and daily movement. Precision thin brush reaches inner and lower lashes for detailed application and tightlining close to the lash line. Key attributes Function: lengthening and defining mascara that resists smudging and running during normal daily wear. Finish: classic black for strong, even color payoff. Brush: thin, narrow applicator designed for precise, controlled application and easy access to short or sparse lashes. Performance: buildable formula for one natural coat or layered length without heavy buildup. Size and packaging: compact tube for convenient storage and easy handling. Why you need it If you want longer looking lashes without heavy volume or visible clumps, the thin brush and lengthening formula apply product evenly from root to tip. If you need makeup that stays put through a busy day or seasonal humidity, the waterproof and smudgeproof properties reduce transfer and flaking. If you prefer precise application for lower lashes or for tightlining, the slender brush offers control that wider wands cannot. How to use Start at the base of lashes and gently comb the brush upward to the tips for even lengthening. Apply a second coat after the first coat dries slightly to build length without heavy texture. Use the thin tip to carefully define inner corner and lower lashes. Practical use scenarios Daily commute or long workday when you need lashes that stay defined from morning to evening. Outdoor events in warm or humid conditions where resistance to smudging and running matters. Evening looks that require precise definition near the lash line or on shorter lower lashes. What to expect Noticeable length and separation with classic black color, precise application using a thin brush, and reduced smudging compared to nonwaterproof mascaras.
