The idea of using Botox before wrinkles appear might seem surprising to some — but it’s quickly becoming one of the most sought-after approaches in modern aesthetics. Known as “preventative Botox”, this treatment helps stop fine lines from forming and deepening, allowing you to maintain smooth, youthful skin for longer. But what’s the ideal age to start? And how do you know if it’s right for you?



At Mesglo Aesthetic Clinic London, we specialise in subtle, personalised anti-ageing strategies that preserve your natural features. Here’s our expert breakdown of when — and why — preventative Botox may be worth considering.



What Is Preventative Botox?



Preventative Botox is the use of botulinum toxin to relax specific facial muscles before dynamic lines (wrinkles caused by repeated facial expressions) become static lines (etched into the skin at rest).



By treating the muscles early, you can prevent habitual creasing from forming deep-set lines in areas such as:



- Forehead (horizontal lines)



- Glabella (frown lines / “11s”)



- Crow’s feet (outer corners of the eyes)



The goal isn’t to freeze the face — it’s to reduce overactivity while preserving natural movement.



What’s the Best Age to Start Preventative Botox?



There’s no universal “perfect age” — the best time to begin depends on your genetics, lifestyle, skin type, and facial habits. That said, most people consider starting between their mid-20s and early 30s.



✅ Mid-20s to Early 30s



This is when many begin to notice subtle expression lines lingering after frowning or raising the brows. If you:



- Have visible lines forming when your face is at rest



- Notice deep creases after years of strong expression



- Want to age gracefully without drastic changes
