BY TRYBELLO
May 31, 2026
Key Takeaways
- The three brands differ mainly in formulation: UKLASH and RevitaLash both rely on peptides paired with low-dose prostaglandin analogs, while Trybello Eyelash Growth Serum uses a fully plant-based blend with no prostaglandins, hormones, oils, silicones, parabens, fragrance, or PEGs.
- On cost, Trybello Eyelash Growth Serum is priced at $39.95, UKLASH Lash Growth Serum is £39 (roughly $48 to $50 USD), and RevitaLash Advanced ranges from $59 for the 1.0 mL up to $152 for the 3.5 mL six-month supply.
- For results, all three serums show visible changes within 4 to 8 weeks of consistent daily use, with Trybello Eyelash Growth Serum users commonly reporting fuller, longer lashes within 4 to 6 weeks through plant-based actives like panax ginseng and pentapeptide-17.
- Side effects vary widely: RevitaLash discloses risks like redness, lash-line darkening, and dry eyes from its prostaglandin analog, UKLASH reports occasional mild irritation in early weeks, and Trybello Eyelash Growth Serum is formulated to remove the most common ingredient triggers entirely.
- Trybello Eyelash Growth Serum stands out as a US-based, vegan, and cruelty-free option backed by a 60-day growth guarantee, with a dual-wand design that combines a serum applicator and mascara wand for easier daily use.
What is the Difference Between UKLASH, RevitaLash, and Trybello Lash Serums?
The right lash serum among UKLASH, RevitaLash, and Trybello depends on what matters most to you across price, visible results, and ingredient safety.
RevitaLash Advanced positions itself as a clinical option with prices climbing to $152 for its six-month supply, while UKLASH and Trybello Eyelash Growth Serum both sit closer to the $40 range with very different formulation approaches. UKLASH and RevitaLash include low-dose prostaglandin analogs alongside peptides, which can drive quicker visible changes but also raise the risk of redness, dry eyes, and pigment shifts around the lash line.
Our Trybello Eyelash Growth Serum, made by a US-based clean beauty brand, skips that ingredient class entirely and leans on plant-based actives such as panax ginseng, pumpkin seed extract, and pentapeptide-17, paired with a dual-wand applicator that simplifies daily use.

UKLASH Eyelash Serum Price
UKLASH Lash Growth Serum is applied along the upper lash line once daily using its precision applicator brush.
UKLASH Lash Growth Serum is priced at £39 for a one-time purchase of the 3mL tube, or £31.20 with their 20% off subscribe-and-save option.
In US dollars, this lands at roughly $48 to $50 at current exchange rates, with third-party retailers sometimes listing the product between $45 and $55 USD.
RevitaLash Eyelash Serum Price
RevitaLash Advanced sits at the higher end of the lash serum category. The 1.0 mL size retails for $59, the 2.0 mL (three-month supply) is $100, and the 3.5 mL (six-month supply) is $152.
The brand also offers RevitaLash Advanced Pro at $185 and RevitaLash Advanced Sensitive at $106.
Trybello Eyelash Growth Serum Price
Trybello Eyelash Growth Serum is currently priced at $39.95 (down from $49.95), reflecting a clean, plant-based formula built around premium actives like Panax ginseng, pumpkin seed extract, and pentapeptide-17.
What makes our product distinct is its 2-in-1 dual wand design: one end holds the eyelash serum, and the other holds mascara, so you get two complementary lash care steps in a single product.
The serum applicator delivers a precise stroke along the lash line, while the mascara wand handles your daily lash look.
Visible Results: UKLASH vs RevitaLash vs Trybello
UKLASH Eyelash Serum Result
UKLASH users generally report noticeable changes in lash length and density within 4 to 8 weeks of consistent daily use.
The formula combines peptides like biotinoyl tripeptide-1 and myristoyl pentapeptide-17 with a botanical complex and a measured amount of a prostaglandin analog.
Most users see fuller results around the 12-week mark, with the brand recommending three to four weekly applications afterward to maintain the look.
RevitaLash Eyelash Serum Result
RevitaLash Advanced Eyelash Conditioner contains peptides, biotin, and a prostaglandin analog.
RevitaLash Advanced is positioned by the brand as a physician-developed lash conditioner. Per RevitaLash, users may begin to see visible changes in lash appearance within 4 to 6 weeks of consistent daily use, with continued improvements reported over longer use.
The formula includes peptides, biotin, botanical extracts, and a prostaglandin analog (cloprostenol ethyl amide in the latest reformulation). As with most lash serums, the brand notes that results vary by individual and that ongoing application is needed to maintain the conditioned-lash look.
Trybello Eyelash Growth Serum Results
Trybello Eyelash Growth Serum is built around a plant-based blend that includes panax ginseng, pumpkin seed extract, grape seed extract, and pentapeptide-17.
With consistent daily use, customers commonly report visible improvements in lash fullness and length within 4 to 6 weeks, with continued progress reported through weeks 8 and beyond.
The dual wand design also adds a practical layer to the routine. One end delivers the eyelash serum, while the other functions as a daily mascara, so your lashes look defined while the serum works along the lash line. Every order is also covered by our 60-day growth guarantee, giving you the room to test our Trybello Eyelash Growth Serum and decide for yourself.
One of our customers, Kenikeni, experienced visibly fuller and longer lashes after using our lash serum consistently for one month.
UKLASH vs RevitaLash vs Trybello: Side Effects
UKLASH Eyelash Serum Side Effects
UKLASH discloses that its main Lash Growth Serum contains a low-dose prostaglandin analog (isopropyl cloprostenate), and reported side effects on the brand's site and review pages tend to be mild. These include occasional redness, minor irritation, and some sensitivity during the first few weeks of use.
The brand recommends patch testing before first use and advises against application during pregnancy or while nursing. For users who prefer to avoid this ingredient class altogether, UKLASH also has prostaglandin-free options in its Sensitive and Complex Peptide serums.
RevitaLash Eyelash Serum Side Effects
RevitaLash Advanced contains a prostaglandin analog (cloprostenol ethyl amide in the latest formulation), and the brand lists possible side effects in a small percentage of users. These include temporary redness, swelling, itching, burning sensation in the eyes, dry eyes, watering, styes, temporary darkening of the skin at the lash line, periorbital fat loss, and eyelash loss.
RevitaLash also notes that these effects are uncommon and that it is not confirmed whether they are caused by the product or other factors. Users with eye conditions, dry eyes, or those who are pregnant, nursing, or undergoing treatment for glaucoma or cancer are advised by the brand to avoid the product.
Trybello Eyelash Growth Serum Side Effects
Trybello Eyelash Growth Serum is designed for comfortable daily use across a wide range of users.
We formulated our Trybello Eyelash Growth Serum without prostaglandin analogs, hormones, oils, silicones, parabens, fragrance, or PEGs, which removes the most common ingredient triggers tied to lash serum sensitivity.
For anyone with sensitive eyes, contact lens wearers, or users who have reacted to other lash serums in the past, our Trybello Eyelash Growth Serum offers a daily option formulated with plant-based actives such as panax ginseng, pumpkin seed extract, and pentapeptide-17. The formula is vegan, cruelty-free, and produced by our US-based team. As always, a patch test is a smart first step before introducing any new product around the eye area.

What Makes Trybello Stand Out From Other Lash Serums?
Our Trybello 2-in-1 Eyelash Serum and Mascara Dual Wand combines lash care and daily lash definition in a single product.
Across cost, results, and side effects, the right lash serum depends on how you weigh faster initial changes against ingredient sensitivity and long-term comfort. RevitaLash and UKLASH lean on prostaglandin-driven results, while a clean, plant-based formula keeps daily use comfortable for a wider range of users.
At Trybello, we formulated our Trybello Eyelash Growth Serum with peptides and botanical actives so you get visible fullness without the side effects tied to prostaglandin analogs. If you want to learn how our dual-wand serum fits into your daily routine, take a closer look here.
