When it comes to maintaining flawless nails, acrylics are a popular choice for their durability, customisability, and long-lasting beauty. But one question many clients ask is: How many times can you have infills on acrylics? Let’s dive into the details of infills, how long acrylic nails last, and how to keep your nails in perfect condition for as long as possible.
What Are Acrylic Nail Infills?
Infills are the maintenance step that keeps your acrylic nails looking fresh and flawless as your natural nails grow. During an infill appointment, the gap between the acrylic and your natural nail (created by nail growth) is filled with new acrylic, and the whole nail surface is then buffed and reshaped for a smooth finish.
How Many Times Can You Infill Acrylic Nails?
The number of times you can infill acrylic nails depends on factors like nail health, care habits, and the original application. Generally, you can infill acrylics up to 3–4 times before needing a full removal and new set.
Here’s why:
- Natural Nail Growth: As your nails grow, the balance of the acrylic may shift, which can affect the overall structure. Some folks like to trim down the natural nail below the acrylic, particularly if they have nails that don’t grow strong and straight.
- Appearance: With repeated infills, you may start to notice banding in the acrylic—a line for each infill matching the shape of the cuticle. Over time, these lines can become unsightly due to discolouration caused by sun exposure, staining, or general wear.
- Nail Health Check: Regular removal allows me to assess the condition of your natural nails and ensure they remain healthy.

The Benefits of Using a Clear Acrylic Base
One technique I like to use is adding a thin layer of clear acrylic as a base on all acrylic sets. This clear layer has a few key benefits:
- Monitor Nail Health: I can file off the top acrylic, allowing me to see your natural nails through the transparent base at each infill, checking for any issues, such as pocket lifting, cracks, or infections.
- Allows Design Changes: With a thin, clear base, your acrylic designs can be changed without removing all the acrylic.
- Prevents Unnecessary Soak-offs: If we’re not removing all the acrylic to change the design at each fill, we’re not over-filing the nail plate or soaking in acetone too frequently.
However, it’s worth noting that not all nail techs use this technique; some may use a single nude or cover pink acrylic, some may use clear acrylic for the whole enhancement and then paint a colour/nude over the acrylic. If you’re having intricate acrylic designs, coloured or glittered acrylic, I highly recommend having that transparent base layer.
How Long Do Acrylic Nails Last?
With proper care, your acrylic nails can last 6–8 weeks with regular infills every 2–3 weeks. This timeline ensures they stay strong, look great, and remain comfortable. Stretching infill appointments longer than 3 weeks can lead to lifting, which increases the risk of damage or infections. Many nail techs may charge for a complete set if you go too long between fills because removing all the lifting and prepping the nails for infill often takes longer.
Signs It’s Time for a New Set of Acrylics
While infills are a great way to extend the life of your acrylic nails, there are times when starting fresh with a new set is the best choice, and let’s be honest, who doesn’t love a fresh set?
Watch for these signs:
- Lifting or Separation: If the acrylic starts to lift from the natural nail, it’s time for removal.
- Banding or Discolouration: If you start noticing discoloured lines from previous infills, it’s time to refresh with a new set.
- Natural Nail Growth: Significant growth may affect the shape and structure of the acrylic.
How to Make Your Acrylic Nails Last Longer

- Protect Your Nails: Wear gloves for chores like cleaning or gardening to avoid damage, especially when using cleaning products or chemicals that could stain or damage your nails.
- Moisturise Daily: Apply cuticle oil twice a day to keep nails and skin hydrated.

FAQs About Acrylic Nail Infills
Q: How many infills can you get before a new set is needed?
You can typically infill acrylics about 3–4 times. After this, it’s recommended to remove the old set and start fresh to ensure nail health and maintain a clean appearance.
Q: How do I know when to replace my acrylic nails instead of infilling?
Signs that it’s time for a new set include yellowing or discolouration, weakened acrylics, or difficulty adhering fresh acrylic during fills. Your nail technician can guide you based on the condition of your nails.
Q: What’s the difference between an infill and a new set?
An acrylic refill involves filling the gap near your cuticle as your natural nails grow out, whereas a new set replaces all the old acrylic, offering a fresh base and design.
Q: How often do acrylic nails need infilling?
Acrylic nails typically need to be filled every 2–3 weeks. Regular appointments help prevent issues like lifting or cracks that can lead to more extensive damage.
Q: Can you switch nail designs with infills, or do you need a new set?
You can switch nail designs during an infill if the acrylic base is still intact. This involves removing or painting over the old design. However, for drastic changes, such as length or shape, a new set may work better.
Q: Are infills better than getting a full set every time?
Infills are cost-effective and less time-consuming compared to a new set. They also reduce the wear on your natural nails, making them a preferred option for ongoing maintenance.
Q: What are the risks of skipping acrylic nail infills?
Skipping infills can result in lifting, cracks, and stress points in the acrylic, which may lead to infections or damage to your natural nails. Regular upkeep ensures the acrylic stays secure and hygienic.
Q: How do acrylic nail infills compare to gel nail maintenance?
Acrylic infills are similar to gel nail maintenance in frequency and process. However, the materials and curing methods differ. Gel nails are lighter and more flexible, while acrylics are sturdy and can hold intricate designs.
Q: Can you fill acrylic nails yourself at home?
While it’s possible, DIY acrylic infills can be challenging and may lead to uneven application or lifting. It’s best to visit a professional for precise and safe results.
