Longer, Thicker, Darker Lashes—No Extensions Required
If you’ve been relying on mascara, lash extensions, or falsies for fuller lashes, there’s a more natural, lasting solution. At Preventous Cosmetic Medicine, we offer a prescription eyelash growth serum that stimulates real, measurable eyelash growth—helping you achieve fuller, darker lashes with a simple at-home routine. No salon visits, no adhesives, no daily reapplications—just your own lashes, enhanced.
- Physician-prescribed, at-home treatment
- Supports longer, thicker, darker lashes over time
- No extensions, fills, or adhesives required
What to Expect
Lash growth begins gradually, with visible improvement in about 4 weeks and full results after 16 weeks of consistent nightly use.
The serum is applied along the upper lash line before bedtime using a sterile applicator. It works by lengthening the active growth cycle and increasing the number of lashes that develop.
If you stop using the serum, your lashes will gradually return to their natural length and thickness over several weeks or months.
Key Benefits of Eyelash Growth Treatment

- Overseen by a Preventous physician for safety and precision
- Eliminates the need for extensions or falsies

How Eyelash Enhancement Works
This physician-prescribed serum is applied once nightly to the upper lash line. It enhances lash growth by:
- Extending the active growth phase (anagen phase) — allowing lashes to grow longer.
- Increasing the number of active follicles — creating a denser lash line.
Virtual consultations are available and typically take less than 15 minutes. During your visit, a Preventous consultant will evaluate your lash health and determine whether this treatment is suitable for you.
Downtime
There is no downtime with eyelash growth serum use. You can continue all regular activities as usual. Any mild side effects, such as eye redness or irritation, are typically short-lived and uncommon.
Maintenance
To maintain your results, continued nightly use of the serum is recommended. If you stop applying the product, lash growth will gradually return to baseline. After your 16-week cycle, your physician may advise you on long-term use based on your lash health and goals.
