OSBY™ Lash Growth Serum
The clinical-grade serum that turns weak, thin lashes into your biggest flex.
Noticeable Results in 2 Weeks
Thicker, Longer, Darker Lashes
Rich in Vitamins & Extracts
Paraben & Prostaglandin Free
Watch Out For Cheap Replicas.
Only OSBY™ uses clinical botanicals + zero prostaglandins, ensuring real growth without irritation, inflammation, or lash fallout.
Will this actually work for MY lashes?
+
Yes — even if your lashes are short, sparse, damaged from extensions, or barely grow at all.
Our formula uses clinically backed botanicals like Pumpkin Seed Extract, Ginseng, and Swertia Japonica to stimulate weak or inactive follicles. Most customers see noticeable length and thickness within 2–4 weeks, even if other serums failed them. Your natural growth cycle responds quickly once it's nourished and activated properly.
What if it irritates my eyes?
+
This formula was specifically made for sensitive eyes and contains zero prostaglandins—the harsh ingredient in many drugstore and prescription serums that causes redness and burning.
OSBY’s serum uses soothing, non-irritating extracts and conditioning provitamins that are safe for daily use.
No burning, no redness, no discoloration — even customers who couldn’t tolerate Latisse use this comfortably.
How long does it take to actually see results?
+
You’ll see early conditioning and slight length improvements around 2 weeks.
You’ll see real, visible growth at 4–6 weeks.
Your full transformation — thick, dark, lifted lashes — happens between 8–12 weeks.
We built the formula for fast activation, so the growth cycle kicks in quicker than traditional lash serums.
What happens if I stop using it?
+
Your lashes stay long through their natural growth cycle, but eventually return to your baseline length over time — just like stopping biotin or hair vitamins.
To maintain your full results, most customers simply switch to 3–4 uses per week after reaching their desired length.
No shedding, no sudden loss — just a gradual return to normal if usage stops completely.
