How Long To See Results?
How Long To See Results?
Most customers begin noticing subtle improvements within the first few weeks of consistent use, with more visible changes typically appearing from around week 4 onward.
Everyone’s natural lash cycle is different, so some people may see their desired results sooner, while others may need more time.
For the best results, use the clear serum consistently at night and the black serum during the day as directed. We also recommend taking a close-up photo of your lashes before your first use so you can compare your progress over time.
60 Day Guarantee
60 Day Guarantee
If you don’t notice a meaningful improvement in the appearance of your natural lashes within 60 days of consistent use, contact us and we’ll help you request a refund.
How It Works
Step 1: Use It Consistently
Apply the clear serum at night and use the black serum during the day as directed. Consistent use gives the formula the best chance to support your lashes over time.
Step 2: Give It Time
Lash growth is gradual. Some customers begin noticing subtle changes within the first few weeks, with more visible length and fullness typically appearing from around week 4 onward. Depending on your natural lash cycle, results may continue developing over 8–12 weeks.
Step 3: Not Satisfied? Contact Us
After completing 60 days of consistent use, email orders@averastore.co with your order number.
Our team will review your request and guide you through the next steps.
Track Your Progress
We recommend taking a close-up photo of your lashes before your first use, then comparing again every few weeks. Gradual changes in length, fullness and lash-line density are often easier to notice in photos than day to day.
LONGER LASHES IN JUST 4 WEEKS.
No more falsies. No more extensions. Supercharge your natural lashes in just 4 weeks.

Testimonials
-
I bought this mainly because I wanted a prostaglandin-free option. Another serum left me with dark shadows around my lash line, so I was nervous about trying anything again. I’ve used this consistently for nearly two months with no irritation or darkening. My lashes look longer and there are fewer little gaps along the lash line.
-
My lashes are definitely longer and I’ve had no irritation.
-
I didn’t expect anything dramatic, but after six weeks my lashes are clearly longer and look more even across the lash line. It’s a natural difference, but very noticeable in photos.
-
Easy to use and my lashes look longer from the side already.
-
My eyes normally react to everything, so irritation was my main concern. I’ve used the clear serum every night for over a month and haven’t had any stinging or redness. My lashes have also for sure grown a significant amount.
-
I’ve tried other lash serums before and stopped because the skin around my eyes looked darker. I chose this one because it’s prostaglandin-free. So far I’ve had no darkening, and my lashes are looking longer and healthier.
-
Started noticing a difference around week 3. Really happy so far.
-
Heading
I took a photo before starting because I knew I wouldn’t notice small changes day to day. Week 6 now and the difference is obvious. My lashes extend farther past my eyelid and the gaps look less noticeable.
-
My lashes were already fairly decent, just short and straight. After about two months they’re noticeably longer, especially when curled. They look like a better version of my natural lashes rather than extensions.

Frequently Asked
Questions
Is it safe to use?
Yes. The Avera Duo Lash Serum Pro is formulated with the delicate eye area in mind and is free from prostaglandins and prostaglandin analogues.
It uses gentle, lash-conditioning ingredients including peptides, biotin, panthenol and heartleaf extract to support healthier-looking lashes without relying on prostaglandin-based actives.
As with any cosmetic used near the eyes, we recommend completing a patch test before first use. Apply only as directed and avoid direct contact with the eyes.
If irritation, redness or discomfort occurs, stop using the product and consult a medical professional.
Is the black side just mascara?
No. While the black side gives your lashes an immediate darker, more defined appearance, it does not feel or behave like traditional mascara.
The lightweight serum formula coats and separates the lashes without leaving them feeling thick, stiff, crunchy or heavy.
It is designed to provide soft, natural-looking definition while delivering lash-conditioning ingredients throughout the day.
The clear side is your concentrated nighttime treatment, while the black side provides lightweight daytime definition + ongoing lash care.
Will the black serum smudge, feel sticky or make my lashes crunchy?
Apply one light coat and allow it to dry for a few seconds.
The black serum is designed to feel lighter than traditional mascara and provide natural-looking definition without leaving lashes overly stiff, sticky or crunchy.
The formula is water-resistant, helping it stay in place during normal daily wear. However, avoid rubbing your eyes or exposing it to heavy water.
For a darker result, allow the first coat to dry before applying a second.
Is it suitable for sensitive eyes and contact-lens wearers?
The formula is designed with the delicate eye area in mind and is prostaglandin-free.
Apply carefully to clean, dry lashes and avoid direct contact with the eye.
Contact-lens wearers can use it, but we recommend applying the serum before inserting lenses or taking extra care around the lash line.
Always patch test before first use. Discontinue use if irritation, redness or discomfort occurs.
