Top 5 Lash Growth Serums in Ireland (2026)

What Irish Women Are Really Using for Longer, Stronger Lashes in 2026

Tired of lash extensions that cause more damage than drama? You’re not alone.

In 2026, Irish women are continuing to move away from extensions and heavy falsies and choosing eyelash serums that support real, natural lash health. The focus is no longer just length, but strength, fullness, and long-term results, without irritation or unnecessary risk.

But with so many lash serums available in Ireland, which ones are actually worth your time and money?

We’ve reviewed the top lash growth serums Irish women are genuinely using, breaking down ingredients, results, and real-world suitability including two Irish-developed favourites from Lerelle Beauty.

3. UK Lash Eyelash Serum

• Best for: Influencer-loved and internationally recognised

  UK Lash remains a well-known name across Ireland and the UK. Its formula is designed to encourage lash appearance over time and is widely featured online. However, it contains prostaglandin analogues, which may not suit everyone.

  Things to consider:

  Results typically seen after 8–12 weeks

  Contains prostaglandin derivatives

  Some users report sensitivity

💰 RRP: ~€42–€50

4. iGlow Lash Maximizer Serum

Best for: Faster results, but not ideal for sensitive eyes

iGlow is a Scandinavian brand known for strong formulations. Many users report quicker visible results, but reviews are mixed when it comes to comfort, particularly for sensitive skin.

Pros and cons:

• Visible results reported within 4–8 weeks

• Strong formulation

• May cause irritation or discolouration for some users

💻 Available at: iGlow.me
💰 RRP: ~€49 - €55

5. Multi-Peptide Lash & Brow Serum by The Ordinary

Best for: Budget-friendly conditioning

The Ordinary’s lash serum remains a popular entry-level option. It focuses more on conditioning and lash health rather than dramatic growth, making it suitable for beginners or maintenance use.

What to expect:

• No prostaglandins

• Subtle results with consistent use

• More supportive than transformative

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