How Long Do Semi Permanent Brows Last?
Let’s be honest — waking up with perfect brows is the dream. No pencilling, no filling, no hoping you’ve drawn them on evenly. Semi permanent brows have completely changed the game for so many of our clients at Pretty Perfect London, and one of the very first questions we get asked is: “how long will they actually last?”
Great question — and the honest answer is: it depends. But don’t worry, we’re going to break it all down for you.
So, How Long Do They Last?
On average, semi-permanent eyebrows last between 12 to 18 months. However, some clients find their results hold beautifully for up to two years, while others may notice fading sooner. The longevity of your brows is influenced by a number of individual factors, which we’ll explore below.
The key thing to remember is that semi-permanent brows are designed to fade over time — that’s actually a good thing! It means the treatment works with your skin naturally, and adjustments can be made as trends and your preferences evolve.
What Affects How Long They Last?
1. Your Skin Type
This is probably the biggest factor. If you have oily skin, the natural oils in your skin can break down the pigment faster than someone with normal or dry skin. Oilier skin types may find their brows fade closer to the 12-month mark, while drier skin types tend to hold onto the colour for longer. Neither is a problem — it just means topping up a little sooner!
2. Sun Exposure
We love a sun-kissed glow, but UV rays are not your brows’ best friend. Regular sun exposure can cause the pigment to fade more quickly. Wearing SPF around the brow area (once fully healed) and using a hat when you’re out in strong sunshine can genuinely help your results last longer.
3. Skincare Products
Certain skincare ingredients — particularly acids (like glycolic or retinol) — can accelerate pigment fading if used directly over the brow area. This doesn’t mean you need to ditch your skincare routine; it simply means being mindful about applying active products to the brow region.
4. Aftercare
Those first 7–10 days after your treatment are crucial. Keeping the area dry, avoiding makeup over the brows, staying out of steam rooms and swimming pools, and not picking at any flaking skin all play a huge role in how well the pigment settles. Follow your aftercare instructions and your brows will thank you for it!
What About the Touch-Up Appointment?
Here’s something that surprises a lot of first-timers: your initial session is actually a two-part process. After your first appointment, a follow-up touch-up is scheduled for around 4–6 weeks later, once the skin has fully healed.
This touch-up allows us to refine the shape, add any density where needed, and perfect the colour. Think of the first session as the foundation, and the touch-up as the finishing coat. Together, they give you that polished, long-lasting result you’re after.
When Should I Book a Top-Up?
Most clients return for a top-up between 12 and 18 months after their initial treatment. You don’t have to wait until your brows have completely faded — in fact, it’s better not to! Coming back when there’s still some pigment remaining means your therapist can build on what’s there, making the process quicker and the results even more seamless.
Some clients love their brows so much they book in every year like clockwork. Others go a little longer between appointments. There’s no strict rule — it’s completely personal to you and how your skin holds the pigment.
The Bottom Line
Semi-permanent brows are one of the most popular treatments we offer at Pretty Perfect London — and it’s easy to see why. With results that last anywhere from 12 to 18 months (sometimes longer), they offer a genuinely low-maintenance solution for beautifully defined, natural-looking brows.
The key to making the most of your investment? Good aftercare, a little sun protection, and keeping up with your top-up appointments. Do that, and you’ll be waking up to great brows every single day.
