LASH PRIMER 0.28OZ. Benefits: Amino acid and peptide blend strengthens lashes. Part of DIMEs all-encompassing eyelash system. Key Ingredients: Proprietary Peptide Blend: The same incredibly effective peptides utilized in the beloved Eyelash Boost Serum can help improve the appearance of eyelashes by supporting the structure of the hairs themselves.. Amino Acid Blend: Also found in the Eyelash Boost Serum, this blend of amino acids aids in strengthening and restoring hair. Infusing the hair with amino acids is a perfect way to improve your eyelashes' natural appearance.. Formulated Without: Sulfates: DIME products never contain skin-irritating ingredients such as sulfates. Sulfate-free products are gentle on the skin and can help decrease the chances of an allergic reaction.. Phthalates: Certain phthalates (like Dibutyl Phthalate, aka DBP, or DEHP, and DEP) appear on product labels, but most typically remain unlisted, hiding under the term fragrance. Since some phthalates have been linked to hormone disruption, DIME avoids them..
