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
…preventative Botox can be a smart step.
✅ Later 30s & 40s
If lines have already formed, Botox can still be used both preventatively and correctively, often in combination with skin boosters, microneedling or polynucleotides to restore skin quality as well as muscle control.
Factors That May Influence When You Start
🔹 Genetics
If your parents or siblings developed wrinkles early, you may be genetically predisposed. Starting sooner can help delay visible signs of ageing.
🔹 Facial Expressions
If you frown, squint, or raise your brows frequently — even without realising — those habitual movements can accelerate dynamic wrinkle formation.
🔹 Sun Exposure & Lifestyle
UV damage, stress, and smoking can weaken collagen and make expression lines appear sooner. Preventative Botox can slow down this process.
🔹 Skin Type
People with fair, thin or dehydrated skin may show signs of ageing earlier — and benefit from earlier intervention.
How Often Do You Need It?
Preventative Botox doesn’t require constant top-ups. At Mesglo, most clients only need it every 4–6 months, depending on their skin and muscle strength. With regular treatments, the muscles learn to relax, meaning you may eventually need smaller doses less frequently.
What Are the Benefits of Starting Early?
✔️ Delays deep wrinkle formation
✔️ Preserves youthful skin longer
✔️ Requires smaller, less frequent doses
✔️ Avoids the need for more invasive treatments later
✔️ Maintains natural facial movement
Starting early often leads to the most natural, undetectable results — your friends may just think you have great skin, without realising why.
Is Preventative Botox Safe?
Absolutely — when performed by trained professionals. At Mesglo London, all injectable treatments are delivered by experienced aesthetic experts using subtle, anatomically precise techniques. We focus on enhancing, not changing your natural appearance.
