Features

  • ACHIEVE THICKER, FULLER BROWS AND EYELASHES without the use or harmful, irritating ingredients. With just three all-natural ingredients this growth serum stimulates the formation of new follicles while hydrating and repairing existing brow and lash hairs for continued growth even after stopping use.
  • ALL NATURAL FORMULA WITH ZERO HARMFUL SIDE EFFECTS - Our lash & brow serum contains Castor oil, Coconut oil, and Argan oil. Safe for sensitive skin & eyes.
  • BENEFITS - The ingredients in twenty/twenty beauty's eye-friendly makeup and treatments provide effective remedies towards relieving discomfort in eye irritation, fatigue, light sensitivity, heavy eyelids, blurred vision and more.
  • HOW TO USE - Each night, dispense one pump of serum to clean, dry eyelashes with a clean finger, brush or Qtip. Gently apply to the upper and lower lash lines at the root. Add another pump for the eyebrows, smoothing over the entire eyebrow. Leave overnight. Please note there is no harm getting this formula in your eyes. In fact, eye doctors have been using our main ingredient, Castor Oil as a dry eye treatment for many years.
  • CREATED BY AN EYE DOCTOR - Created by Columbia-trained Ophthalmologist Dr. Diane Hilal Campo after seeing harmful effects of other lash and brow serums. This unique pump packaging avoids double dipping wands for safer, sanitary application.

  • FINALLY a clean lash growth serum
After getting lash extension for a wedding (never again!!) I was looking for something that would help me grow back my natural lashes. All the other lash serums out there list harsh side effects like potential changes in your eye color?! I like to keep my entire beauty routine super clean so I'm SUPER happy to have found this product!! Only 3 all-natural ingredients and made by an eye doctor so I can trust it isn't going to cause any strange reactions. I've been absolutely loving it so far and it hasn't irritated my sensitive skin. Best of all my lashes are coming back!! Consistency is key. ... show more

  • No new growth
I purchased this product excited to help my sparse lashes due to aging. I've seen no new growth or increase in thickness of my lashes after faithful use for 60 days.

  • I really need this
So my eyebrows have a kind of chalkboard eraser look. I have tried many different vitamins thinking I was dealing with some sort of deficiency but now I have this product to work with. In a small package this product assures me that it will help with my eyelashes and eyebrows but we won't worry about eyelashes. They are fine. Our focus will be the eyebrows. After getting the product out of the simple box, it took ten pumps to begin to see the product come out. I only selected a very small amount, pea sized at best to start the regimen. In all fairness I know this product will take up to 21 days to show any real benefit but for now I can say there was no adverse reaction to my eyebrow area. No redness or rash and my eyebrow hair did not fall out so these are all positives. As far as actual growth that is going to take a little long to see. I did notice i started getting one stray hair starting to grow on the area just to the right of my left brow so fingers are crossed that I can get rid of the eraser look. ... show more

  • Very expensive, hope this yields proportionate results
You get only 1/3 ounce of castor oil, argan oil & coconut oil for $52. No other ingredients. Box says takes 12 weeks for results, so well out of Amazon's 30 day guarantee. Dunno, seems highly unlikely, but the box shows a before and after photo with significant difference in eyelashes and eyebrows. That's about $156 before noticing results? Worth it if it works and yours are super sparse. I'm going to inquire if they refund your $156 if your results are subpar with your before and after photos because those ingredients alone don't yell let alone scream "we're going to make that big difference." ... show more

  • soothing
I use this as a soothing night-time eye gel that has really helped my dry irritated lids and decreased my dry eye symptoms. I do not appreciate any significant changes in my lashes.

  • First impressions: so far, so good
--Update 1/17-- I haven't used it consistently enough to see how effective it is in lengthening my lashes. However, I use it every 2-3 days to moisturize after a lash perm and haven't noticed any damage or dryness to my lashes like I usually do after a perm. ---FIRST IMPRESSIONS--- I did a patch test on my inner arm and applied it for the first time on my lash line last night. PROS: - Unscented (except for the natural smell of the ingredients) - Pump makes it hygienic - No irritation or burning -- conduct a patch test!! CONS: - Pump makes it inconvenient to apply (though I prefer the better hygiene over convenience). I used one pump on the back of my hand and used a cotton swab to apply it to my lash line, but I might go buy a liner brush. I don't use any on my brows, and one pump was too much for both lashes. I'll update after a few weeks to show progress, if any. ... show more

  • My eyelashes stopped growing and have fallen out
I think this is an overpriced waste of money!! My eyelashes were long when I started using this, and I thought this would help grow thicker. It did not, AND my lashes are half the length as when I started 4 months ago. I had purchased two bottles, one hasn’t been opened yet, and I can promise you…it won’t be ... show more
