Highlights
Summary
DIME's best-selling Eyelash Boost Serum improves the appearance of eyelash length with the proprietary peptide blend.
Benefits
- Enhances the appearance of lashes' length and thickness
- Assists in building up hair for a longer life span
- Does not contain prostaglandins
- EWG VERIFIED
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: Biotinoyl Tripeptide-1 has been shown to have positive effects on hair follicles by promoting scalp micro-circulation and reducing the appearance of follicle atrophy and aging.
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. DIME Lash Boost Serum 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.

- Q
How to use this with eye cream? Thanks
- Asked by dog mom
- Official Answer By DIME Beauty - Brand EngageThat is a great question! Apply the Eyelash Boost Serum first on clean, dry skin, focusing on the lash line (and brows if desired), and allow it to fully absorb for about 1–2 minutes. Once the serum has dried, gently apply your eye cream around the orbital bone using your ring finger. We hope this helps!Was this answer helpful to you

ABSOLUTELY OBSESSED
I cannot explain to you how INCREDIBLE this stuff is! I've had problems with the growth of my eyelashes for YEARS, and I have really sensitive eyes, so I've always debated purchasing an eyelash serum. I had tried the strip lashes and they would just rip out my natural lashes when I would take them o...

I have used other lash serums in the past with great results and no issues or allergies before. I started reading more about finding a serum that didn't contain ingredients that were cleaner and didn't affect long term health of eyes and found Dime. I was super excited to try as they have amazing re...

Bottle came totally empty. Nothing in it.
I opened my bottle and the brush was dry. Repeated multiple times. Shook it up. Finally I pressed my finger securely over the end, and nothing came out. I bought a product for an expensive price that was empty. Ugh.
Was suspicious but ended with success
I've been using this serum for about 13 weeks now, and wow. I saw subtle results within the first three weeks by week nine I was shocked at how long and thick my lash strands grew. It did take about five weeks give or take before the slight burning stopped. Though I use other face serums with active ingredients.
lashes broke off
I used this product for over 6 months. At first it absolutely made my lashes longer but once I reached the 5/6 month mark my lashes started to literally brake and fall out. I had gabs in between that was very noticeable. I had use little clusters/individual lashes for the first time in my life to fill in those gabs. Horrible experience. I'm shocked how many good reviews this has but not everything works for everyone. I immediately stopped using this product and it took a long time (using no lashes products) to grow my lashes back.

Tried consistently for 3 months and used as instructed and the product was not effective. I saw no change in lash length or growth, if anything I've noticed some fall out more than usual. I haven't used lash extensions either, the only change in my routine has been this lash serum. I've had better results from other lash serums from other brands.
