BOOST DUO. Benefits: Convenient two-in-one product wand for on-the-go application. Promotes increased production of eyelash and eyebrow hairs. Improves appearance with a proprietary blend of amino acids and peptides. Key Ingredients: Amino Acids: Collagen is rich in amino acids that your body needs to build keratin, the protein that makes up the hair. These are the building blocks of hair and most of our bodies.. Biotinoyl Tripeptide-1 can have positive effects on hair follicles by promoting the reduced appearance of aging.. Myristoyl Pentapeptide-4: An ingredient that is known to aid in improved hair strength and health.. Formulated Without: Prostaglandins: A common ingredient in eyelash serums that often causes irritation, redness, inflammation, and itchiness. It can also darken the color of the iris permanently. This product is prostaglandin-free, so there's no need to worry about intense irritation or changing of eye color.. 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.. Parabens: Certain parabens have been linked to hormone disruption. DIME prohibits all parabens, including Ethylparaben, Butylparaben, Isobutylparaben, Isopropylparaben, Methylparaben, and Propylparaben.. Fragrance: DIME never uses any form of fragrance, natural or synthetic, in any facial skincare products.. 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..
