Glamour UK has published a 2026 guide to nine eyelash growth serums, naming RevitaLash Advanced and UKLASH Lash Growth Serum as its leading picks. The article draws on staff testing and expert comments, but individual results vary, and the source does not provide full trial data for all nine products.
Glamour UK has published a 2026 guide to nine eyelash growth serums, naming RevitaLash Advanced Eyelash Serum and UKLASH Lash Growth Serum as its leading options. The beauty magazine says its assessment includes staff testing and expert input, while its cited guidance describes results as gradual and individual rather than guaranteed.
The guide calls RevitaLash Advanced one of the most popular products in the category and says multiple members of the Glamour team reported results. Former senior visual editor Chelsea Hughes tested it for six weeks. She said friends and family inspected her lashes to check whether they were natural, describing the change as “phe-nom-en-al.” That is an individual testimonial, not a controlled comparison.
UKLASH Lash Growth Serum is presented as the runner-up. The guide describes it as vegan and cruelty-free, with an amino acid peptide, vitamin B5 and green tea extract. It says the formula is free from parabens and oils and is suitable for use with lash extensions and contact lenses. Those product characteristics are reported by the source; the article does not provide independent testing results for every claim or a full side-by-side breakdown of all nine products in the supplied material.
Glamour’s experts say users generally need regular application over several weeks. RevitaLash global master educator Claire Larsen cited an independent consumer study of 63 participants: after six weeks of daily directed use, 98% reported improved lash appearance, healthier-looking lashes and stronger lashes. The source does not include the study methodology or say whether those results were independently reviewed, so the figures should be read as reported consumer feedback rather than proof that every user will see the same outcome.
What Serum Shoppers Should Know
The guide gives shoppers a comparison point in a category where products differ in ingredients, price, claims and compatibility with extensions or contact lenses. Its emphasis on daily use and patience matters: expert comments in the article put noticeable changes at around six weeks, while UKLASH founder Nima Pourian says products are commonly advised for eight to 12 weeks to cover an eyelash growth cycle.
The evidence described is not equivalent to a clinical review of all nine products. Readers should distinguish editorial testing and testimonials from controlled research, and check each product’s ingredient list and instructions before use. The guide also flags possible redness or irritation, making caution relevant because the products are applied close to the eyes.

How the Guide Assesses Lash Serums
The source is a consumer beauty guide from Glamour UK, rather than a regulatory announcement or a new scientific study. Its headline says “tried & tested,” and its supplied material describes testing by magazine staff, expert explanations of product use and a consumer study cited by a brand educator. The article names nine products overall, but the source material provided here gives detailed descriptions chiefly for RevitaLash and UKLASH.
In the guide, experts explain that lashes pass through growth, transition and resting phases over roughly 12 weeks. Pourian says results depend partly on where a person’s lashes are in that cycle. Larsen says results vary by individual and may be noticeable after six weeks of regular daily use. These are expert comments included in the article, not a promise of a set outcome or timeframe for every user.
““The improvement is phe-nom-en-al!””
— Chelsea Hughes, former senior visual editor at Glamour
Limits of the Reported Results
The supplied source does not give the full list of nine products, their complete testing scores or a detailed comparison of prices and ingredients. It also does not provide the methodology for the 63-person consumer study cited by Larsen, including how participants were recruited or how responses were measured. The reported 98% figures therefore remain attributed to that study as described by the brand educator.
Individual outcomes, the time needed to see changes and the likelihood of irritation remain uncertain. The article mentions redness and irritation as possible effects, particularly with excessive use, but the supplied material does not quantify how often those reactions occur. Its claims about compatibility and product performance should be checked against the specific packaging and current manufacturer instructions.
Check Ingredients Before Applying
Readers comparing the nine recommendations should review the full product list and check current ingredient labels, application directions and warnings before buying. The source advises a patch test, careful use as directed and avoiding overuse; anyone with persistent irritation or concerns about an eye-area product should seek advice from an appropriate health professional. The article offers no confirmed update or further testing milestone, so claims and recommendations may change if Glamour revises its guide.
Key Questions
Which eyelash serums does Glamour UK rank highest?
The guide presents RevitaLash Advanced Eyelash Serum as its leading pick and UKLASH Lash Growth Serum as runner-up. The supplied source material does not include detailed descriptions of all nine products.
How long might an eyelash serum take to show results?
The experts quoted by Glamour say changes may become noticeable after about six weeks of daily use, while UKLASH founder Nima Pourian describes an eight-to-12-week use period. Timing varies by person, and those timeframes are not guarantees.
Can eyelash serums irritate the eyes?
Yes. The guide says some users may experience redness or irritation, particularly if they overuse a serum. It recommends following the product directions and patch testing before regular use.
What may happen after someone stops using a serum?
Benefit makeup artist Lauren Hogsden says users may gradually lose some of the benefits as lashes return to their natural growth cycle. The source does not say that every user will experience the same change.
