Long-Lasting Gel Eyeliners: My Testing Experience with Korean Beauty Essentials I recently revisited the lilybyred Starry Eyes 9 To 9 Gel Eyeliner, which I picked up for ₩7,000 ($5.20) at a Myeongdong Olive Young location. While many viral TikTok Korean makeup products promise all-day wear, I have found that finding one that truly survives an 8-hour workday is rare. This particular liner is a staple in my routine because of its 2mm ultra-slim pencil tip, which makes tightlining the waterline incredibly easy even for those of us with hooded Asian eye shapes. It is currently ranked high in Olive Young bestseller rankings, and after testing it against several competitors, I believe it offers a balanced mix of pigment payoff and longevity for the price.
Why This Gel Liner Is a K-Beauty Favorite



The lilybyred Starry Eyes 9 To 9 Gel Eyeliner is popular because it combines a creamy glide-on texture with a smudge-proof and waterproof formula that sets quickly. It is designed to last from 9am to 9pm, making it a reliable choice for long days in Seoul's humid summer.
Performance and Texture
The product features quick-drying silicone resin technology that locks the pigment in place within seconds of application. In my testing, it did not flake or transfer, even when I applied it to my oily waterline, which is often a challenge for standard pencils.
Application Tips for Beginners
Because the tip is a precise 2mm, I find it best to twist up only a tiny amount to prevent breakage. For those practicing aegyo-sal makeup trends, the lighter shades work perfectly as a soft highlight, while the darker matte shades provide excellent opacity for defining the lash line.
Comparing Top Korean Gel Eyeliner Alternatives
When searching for the perfect liner, it is helpful to compare the lilybyred option with other industry standards available on sites like Stylevana. My top two alternatives for those seeking different finishes or price points are the CLIO Sharp So Simple Waterproof Pencil Liner and the Merzy The First Gel Eyeliner.
CLIO Sharp So Simple Waterproof Pencil Liner
The CLIO liner is often praised on r/AsianBeauty makeup reviews for its ultra-fine tip that allows for extreme precision. It retails for approximately ₩8,500 ($6.30) and is slightly softer than the lilybyred version, which some users prefer for blending out a smokey look.
Merzy The First Gel Eyeliner
Merzy is my go-to recommendation for those who prioritize a multi-proof gel formula that is virtually immovable once dry. It is priced around ₩6,500 ($4.80) and offers a wider range of shimmer finishes compared to the more matte-heavy collection from lilybyred.
Frequently Asked Questions
Q: Does this eyeliner come with a sharpener?A: Yes, it features integrated sharpener functionality at the base of the pencil, which is essential for maintaining the 2mm tip over time.
Q: How does it compare to the Etude House Proof 10 Gel Pencil?A: The lilybyred version is generally considered more pigmented and easier to apply in one stroke, whereas the Etude House option is often favored for its softer, more traditional pencil feel.
Q: Is it suitable for sensitive eyes?A: Many users report that the formula is non-irritating, though as with any long-wear cosmetic, I always recommend using an oil-based cleanser to remove it thoroughly to avoid residue.
Finding the right eyeliner is a personal journey, but focusing on products that offer oil-resistant long-wear will save you from midday touch-ups. If you are building your Korean beauty routine, start with a versatile shade like a dark brown, which provides a softer look than black while still defining the eye effectively.
