Glamour UK has published a 2026 guide comparing nine eyelash growth serums, naming RevitaLash Advanced and UKLASH Lash Growth Serum as its leading picks. The article reports staff testing and expert guidance, but the supplied material does not provide full testing details or independent evidence that every product produces growth.
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 report combines product descriptions, staff testing and expert comments, while warning that results take regular use and can vary between people.
Glamour UK describes RevitaLash Advanced as one of the most popular lash enhancers and says several members of its team reported results during testing. Former senior visual editor Chelsea Hughes tested it for six weeks. In a quoted review, Hughes said friends and family had inspected her lashes to check they were real, calling the change “phe-nom-en-al.” That is a personal account, not a clinical finding.
The report’s other leading pick is UKLASH Lash Growth Serum, which it describes as vegan and cruelty-free. The article says the formula contains an amino-acid peptide, vitamin B5 and green tea extract, and is free of parabens and oils. It presents those features as product details; the supplied source does not include a full ingredient list or comparative test results for all nine products.
Glamour UK’s experts say users may notice a change after about six weeks of daily use, while the article advises using serums consistently for eight to 12 weeks. RevitaLash global master educator Claire Larsen cites 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. These were participant reports, and the source does not describe the study design beyond those details.
Choosing a Serum With Realistic Expectations
The guide offers readers a shortlist in a crowded beauty category, but its findings should be read as editorial product recommendations, not proof that every serum stimulates new lash growth. Glamour UK’s strongest specific evidence in the supplied material is staff experience with RevitaLash and a consumer survey cited by a company educator. Neither establishes that results will be the same for all users.
The practical point is that consistent use and tolerance matter. A product may need weeks of daily application before a change is noticeable, and eye-area irritation can make continued use difficult. Readers comparing the products should check each label, follow the directions and distinguish appearance claims from evidence of actual changes in lash growth.

How the Report Assessed Lash Serums
The source is a Glamour UK shopping guide titled “9 Best Eyelash Growth Serums 2026, Tried & Tested.” It also includes general advice on how to use lash serums, expected timelines and possible side effects. The material supplied here names the two leading products and describes testing of RevitaLash, but does not identify the other seven products or lay out a complete testing protocol.
The article quotes UKLASH founder Nima Pourian, RevitaLash educator Claire Larsen and Benefit makeup artist and brow expert Lauren Hogsden. Their comments explain the companies’ and experts’ views on lash growth cycles, use and maintenance. Readers should note the affiliations: Pourian and Larsen are connected to brands whose products are discussed.
““The improvement is phe-nom-en-al!””
— Chelsea Hughes, former senior visual editor at Glamour UK
Evidence and Product Details Still Limited
The supplied report does not list all nine products, explain how each was tested, or provide comparative results across the full group. It is also unclear from the source whether the consumer study cited by Larsen was independently reviewed or what measures were used beyond participant responses. The article’s broad statements about supporting growth are expert and brand-linked explanations, not proof of a guaranteed effect.
Individual results may differ, and the source notes that redness or irritation can occur, particularly with excessive use. It does not provide rates of adverse reactions or enough detail to compare safety among all nine products. Readers with persistent symptoms should stop using the product and seek appropriate professional advice.
Check Labels Before Starting Daily Use
Readers considering a serum can use the guide as a starting point, then review the product’s complete ingredient list and directions before buying. The experts quoted by Glamour UK recommend a patch test, careful application and no overuse; people with sensitive eyes or concerns about an eye-area product can seek advice from a qualified health professional. The source does not announce a follow-up study or a next testing date, so further comparative evidence is not confirmed.
Key Questions

How long might a lash serum take to show results?
The report says changes may be noticeable after around six weeks of daily use, with use over eight to 12 weeks advised for a full lash cycle. Timing and results vary by person.
Can eyelash serums cause irritation?
Yes. The article’s experts say some users may experience redness or irritation, especially if they use too much. Follow the product directions and consider a patch test before regular use.
