FAQ

Most customers begin to see visible improvements in 3 to 4 weeks, with full results typically achieved by 8 to 12 weeks of consistent daily use.

Keep in mind that lash growth is gradual and varies from person to person. The key is to apply erthlash™ once daily and stay consistent — results build over time, just like healthy skin or hair routines.

Apply one swipe of erthlash™ along the base of your upper lash line, just like you would apply liquid eyeliner. Use it once a day, on clean, dry skin.

Apply erthlash™ once daily, either in the morning or at night — whichever fits best into your routine. Just make sure your lash line is clean and dry before applying. One swipe along each upper lash line is all you need.

Using it more than once a day won’t speed up results and may cause irritation, so consistency (not frequency) is key.

We recommend applying erthlash™ only to your upper lash line. When you blink, a small amount of serum will naturally transfer to your lower lashes — this is all that’s needed for them to benefit.

Applying directly to the lower lash line may increase the risk of product migration into the eye and could cause irritation, especially for sensitive eyes.

Yes — erthlash™ is safe to use with both lash extensions and after a lash lift. Our serum is water-based, oil-free, and lightweight, so it won’t interfere with the adhesive used in extensions or affect the shape of a lash lift.

In fact, many customers use erthlash™ to support natural lash growth and strength while wearing extensions, helping to reduce lash fall-out over time.

If you stop using erthlash™, your lashes will gradually return to their natural growth cycle over time. This means any added length or thickness you gained will slowly reduce, typically over several weeks.

To maintain your results, we recommend continuing with daily use.

Each 5ml bottle of erthlash™ lasts around 5 months with daily use, when applied as directed (one swipe per upper lash line per day).

It has a shelf life of 18 months, and we recommend using it within 12 months of opening to ensure freshness and effectiveness.

Yes, most certainly! Many of our customers also use it on their eyebrows — especially in areas where brows have become thin or patchy.

Simply apply a small amount once daily to clean, dry brows. With consistent use, you may start to see results in just a few weeks.

Yes, you can — many of our customers with sensitive eyes have used erthlash™ successfully by starting gently. If you’re experiencing mild irritation or want to ease into it, try the following tips:

• Apply erthlash™ every other day for the first week to let your eyes adjust.
• Make sure there's no leftover makeup remover, cleanser, or eye cream before applying.
• One thin swipe along the upper lash line is enough. Using more won’t speed up results and could cause irritation.
• Apply just above the lashes, not on the wet inner rim of the eye.
• If using eye cream, wait 10–15 minutes after applying erthlash™.
• If you’re unsure, apply a small amount behind your ear or on your inner wrist for a few days first.
• Store your serum in the fridge for a cooling, soothing application.
• If your eyes are too sensitive right now, you can still enjoy the benefits by applying erthlash™ to your eyebrows.
  

And of course, if irritation continues, it’s best to stop use and consult a healthcare professional. Your comfort and safety come first — always.
