Chantecaille's Longest Lash Mascara fuses the newest lash-growth peptide technology with the original, sought-after Faux Cils formula. Lashes get a boost with Chantecaille's unique SymPeptide 17™, stimulating keratin genes and encouraging the strength and length of your natural lashes - without irritation or discoloration. After two weeks use, in-vivo clinical tests reveal longer and thicker lashes by 25%. These extraordinary results are achieved by simply applying the mascara to eye lashes, daily. Similar to the original Faux Cils formula, Longest Lash Mascara creates immediate volume with a special combination of natural waxes to thicken and plump lashes. Chantecaille's signature Rosewater is added for a luxurious and healing experience. The formula features the non-clumping, double helix brush to comb and feather lashes for clump-free volume.
