3. UK Lash Eyelash Serum

Best for: Internationally recognised & influencer-loved

A cult favourite, UK Lash is popular for a reason. It contains powerful peptides and extracts designed to encourage growth, and you’ll often spot it on beauty influencers’ pages. But with prostaglandin derivatives, some users have reported irritation.

💰 RRP: ~€42–€50

4. iGlow Lash Maximizer Serum

Best for: Visible growth but mixed reviews

iGlow has made a name for itself across Europe with strong lash-boosting results. However, some reviews mention stinging or discolouration around the lash line  usually from the prostaglandin content.

• Fast results, often in 4–8 weeks

• Strong formula, but may not suit sensitive eyes

• Norwegian brand

💻 Available at: iGlow.ie or pharmacies
💰 RRP: ~€49 - €55

5. The Ordinary Multi-Peptide Lash & Brow Serum

Best for: Budget-friendly option

The Ordinary’s serum is affordable and accessible, but with its mild formulation, results are more subtle and take longer to appear. Great for beginners, but not as powerful as others on the list.

• No prostaglandins

• Takes 10–12 weeks to see subtle growth

• More conditioning than transformative

💻 Available at: Boots, LookFantastic
💰 RRP: ~€16
