Do lash primers do anything?

Mascara has only the bare lash to hold. UnderSense® 3-in-1 Maximizing Lash Primer is the base that goes on before mascara. It gives mascara something to grip, so the color that follows lands with more visible volume, length, and definition.

Its light-beige tint means you see every coat as you place it, so placement is deliberate, and it makes mascara color look richer. Soft waxes keep each coat smooth and buildable instead of clumping; the small wand reaches short lashes. Apply to top and bottom lashes, adding coats for more length. Then let it fully dry. That dry-down is your cue for mascara, and the base it leaves helps mascara last longer.

Jojoba Esters are the conditioning agent, and the primer's film stays flexible as it builds, coat on coat. The UnderSense formula names every peptide in it, and our peptide map follows Acetyl Tetrapeptide-3 with Clover into brows and scalp. Shop UnderSense.

LashSense FiberExtend Mascara is the next step over fully dry UnderSense when you want even more volume and color. The primer builds the base; the mascara finishes it.
