Butterfly Needle vs. Straight Needle: A Comprehensive Comparison

What cosmetic or aesthetic enhancements are predominantly performed with needles? Have you had or explored either of them? If you have, do you know what needle the practitioner used and why?

Well, several cosmetic procedures employ needles. While some are primarily needle-based, others involve needles as secondary tools. These procedures involve different types of needles, including straight and butterfly needles.

For this piece, we’ll focus on butterfly needles vs. straight needles, helping you identify and compare them. Get to understand how they impact overall procedure experience and when they come into play in the aesthetics space.

What is a Straight Needle?

Ever undergone suturing, venipuncture, or cosmetic filler application? If you have, you’ve likely seen straight needles of varied lengths and sizes.

True to its name, a straight needle is uniformly straight, without angles or curves. It has a smooth, cylindrical and sturdy stainless steel body for seamless insertion into a vein or the skin.

Generally, a straight needle’s body is usually attached to a rigid and hollow plastic for fitting or attaching the needle to syringes and other delivery devices.

Why medical stainless steel?

Medical stainless steel not only protects the needle from rust, it also enhances safety during procedures such as drug administration or dermal filler injection. How?

Stainless steel is non-toxic (it does not release harmful substances), making it safe for both external and internal procedures. Moreover, it is unlikely to trigger allergic reactions or skin irritation.

Besides ensuring your safety, stainless steel’s strength makes it possible to have a sharp beveled tip (designed to facilitate smoother penetration into veins or tissues, minimizing discomfort).

What is a Butterfly Needle?

Just like a butterfly, this needle type has two plastic wings or extensions attached to its body. The wings are broad and light based on the size or gauge of the needle, enhancing stability and grip during procedures.

Similar to a straight needle, a butterfly needle is made of stainless steel and has a sharp beveled tip for safety and to manage discomfort respectively. However, most butterfly needles tend to be short.

So, a set of plastic wings, stainless steel body, mostly short, and lastly — flexible tubing and a hub. That’s a butterfly needle!

On one end of the flexible tubing is the needle and on the other a hub to securely attach IV lines or syringes.

Why the wings and flexible tubing?

You see, winged infusion needles or butterfly needles are designed to improve grip, maneuverability, and stability during blood draws or infusions.

With a straight needle, controlled blood draws and infusions for a long period are pretty challenging and uncomfortable for patients. Butterfly needles were born to solve this problem.

Butterfly needles can be taped in place to keep it stable and prevent movement.

Furthermore, since the flexible tubing can wiggle around, the patient is unlikely to feel the pain that comes with sudden needle shifts.

That’s why you’ll come to realize that butterfly needles are mostly recommended for those with delicate veins.

For instance, those with deep-set or hard-to-spot veins, children, or elderly patients. A butterfly needle improves accuracy and comfort, enhancing their experience.

To understand how butterfly needles differ from straight needles based on the experience they deliver, keep exploring this piece. Get to also understand how their differences impact procedure pricing and more.

Understanding Butterfly Needles vs Straight Needles: Key Differences

Sometimes, all you may need to mentally prepare for a needle-based aesthetic or medical procedure is prior information. Knowledge and understanding helps kill fear and uncertainty, especially in the needle-phobic ones.

Express preference and become a part of the decision-making process when it comes to needle-based procedures with the help of this comprehensive butterfly needles vs. straight needles comparison. In this comparison, we focus on:

1. Suitability for sensitive or delicate areas

While both straight and butterfly needles are used in delicate or sensitive areas, butterfly needles are the go-to option. Why?

Butterfly needles are by default designed to work with small or delicate veins like those on your feet, hands, or in children or elderly people.

When working around a delicate or sensitive area, the wings on a butterfly needle provide grip, allowing your select practitioner to precisely puncture the target veins.

Then, to reduce the chances of movement, the practitioner secures the wings using tape. And, if the needle happens to move, the flexible tubing lowers the risk of discomfort, bruising, or even vein damage.

Remember, when appropriate, your practitioner chooses a straight needle to quickly reach deeper veins. However, they take extra caution, depending on how sensitive or delicate the treatment area is.

2. Potential for tissue injury

When it comes to tissue damage, both have the potential to cause tissue damage. However, straight needles are more likely to cause tissue damage, especially when not used correctly and carefully.

Since most straight needles are large and stiff, improper movement or insertion leads to puncture wounds, bruising, and other tissue injuries. This needle needs a practitioner with more skill and precision.

Butterfly needles, on the other hand, have smaller and gentle needles paired with flexible tubing. These two design aspects combined with the wings ensure once the needle is in place, it is unlikely to cause much disturbance to the surrounding tissue in case of sudden shifts.

Despite the differences, it does not mean that a practitioner without experience is a great match for butterfly needles. When either needles are in use, the practitioner must use proper technique to minimize injury risks.

3. Control, stability, and extent of discomfort

Speaking of butterfly needles vs. straight needles, these three contrast points are the most talked about. When deciding what needle to use, your practitioner first assesses the degree of control, stability, and comfort required.

Butterfly needles offer greater control, stability, and minimal levels of discomfort. While the wings provide a stable grip for gentle insertion, the flexible tubing minimizes discomfort during movements.

So, in case you are to undergo a dynamic procedure or one that needs you to move from one area to the other, a butterfly needle is the most suitable option. The flexible tubing reduces strain on the injection site, allowing you to move comfortably.

Unlike butterfly needles, straight needles need stable hands. Any slight technique mistake and you are likely to suffer more discomfort.

Your practitioner will bring out a straight needle when they need to inject a part of the treatment area quickly and with greater precision.

For instance, practitioners often choose a subcut gauge needle for insulin or other small-volume injections.

4. Safety and hygiene protocols

By default, we manufacture butterfly and straight needles for single use.

Once used, the practitioner must discard the needle  immediately to avoid cross-contamination. Despite this, when handled improperly, straight needles are more likely to break sterility. How?

Straight needles have a small and rigid plastic handle. This increases the likelihood of direct handling or contact with the needle itself during procedures, increasing the risk of contamination, infections, or complications.

Since butterfly needles have wings attached to the needle, the practitioner has a grip point, maintaining sterility. This is super beneficial in dynamic environments where the practitioner needs to make some adjustments or when the procedure involves multiple attempts to access obscured or poorly visible veins.

5. Range of needle gauge options

When deciding between butterfly needles vs. straight needles, your practitioner figures in factors such as procedure type and vein accessibility. And, for vein preservation, your practitioner selects butterfly needles.

Butterfly needles are generally built for venous access and blood extraction. That’s why they are generally available in mid-range gauges, including 21 - 25. Also, their range of needle gauge options is lower.

Compared to butterfly needles, we tend to manufacture a broad range of straight needle gauges. From very fine to thicker ones, allowing practitioners to draw or administer larger volumes of blood or other fluids.

Overall, it is your practitioner’s responsibility to select the right needle gauge to ensure optimal comfort. Even though butterfly needles come first, always mentally prepare for a switch to straight needles, managing uncertainty and fear.

Take IV procedures, smaller IV needle gauge sizes like the 24-gauge needle are ideal for sensitive areas. On the flip side, larger sizes are preferred for rapid fluid administration.

6. Impact on service fees or procedure cost

Yes, the needle type used during a procedure does affect the overall cost.

Butterfly needles increase the cost of a procedure unlike straight needles. That’s because butterfly needles have a specialized design — specifically for blood draws or fluid delivery.

The manufacturing process involves designing the wings and flexible tubing in a way that they do not get in the way of the procedure. The two are made sturdy enough to sustain pressures of different levels during handling, enhancing patient comfort.

Apart from the design elements, butterfly needles are curated to serve those with sensitive veins or reaching hard-to-access veins.

While costly, you’ll realize that butterfly needles are worth the expense, especially when comfort and precision are a priority. Moreover, children and the elderly benefit greatly from the availability of butterfly needles.

Straight needles are mostly affordable because of few manufacturing requirements. That’s why they have a broad range of gauges and are available for routine cosmetic or medical procedures.

To at least save on cost, online platforms and medical supply organizations often list butterfly needles for sale in bulk, allowing clinics to procure the needles at a fairer price.

Now that you understand how these two needles impact your overall experience, here is a look into the procedures you can expect to see them in use.

When and where do they come into play?

In the aesthetics industry, you’ll find that straight needles are used in procedures that require precise injections or targeting specific skin layers. Some of these procedures include:

Applications of straight needles in the aesthetic industry

1. Dermal filler injections

Fillers offer an effective solution for volume loss, wrinkles, lip plumping, nose reshaping, and more. For precise application, straight needles of different gauges are used to reduce discomfort and instances of asymmetry or formation of lumps and bumps.

2. Mesotherapy

Mesotherapy involves the injection of a select mix of enzymes, hormones, vitamins, and other ingredients into the skin’s middle layer to solve various cosmetic concerns. Some concerns it resolves include fat reduction, pigmentation issues, and hair loss.

3. Botox injections

Botox injections involve the use of fine needles to precisely deliver botulinum toxin (Botox) into specific parts of the body. Botox then relaxes the muscles within the treatment area, helping resolve cosmetic issues like forehead lines, crow’s feet, frown lines, and wrinkles on the neck.

Straight needles are generally more versatile than butterfly needles in the cosmetic or aesthetics industry.

Besides these three applications, you’ll realize that straight needles are also a part of specialized devices like those used for microneedling.

That said, butterfly needles are used in the following aesthetic procedures or treatments due to their precise and gentle design.

Applications of straight needles in the aesthetic industry

1. Pre-treatment and post-treatment monitoring

Certain cosmetic procedures require prior blood tests to assess compatibility. For such treatments, butterfly needles are used to improve overall experience.

2. Platelet-rich plasma (PRP) therapy

To prepare PRP, a portion of your blood is required. Butterfly needles are preferred for drawing blood, which is then placed in the centrifuge to prepare platelet-rich plasma.

Overall, butterfly needles are not used that much in the aesthetics industry. They mostly come in handy when the practitioner needs to draw blood or deliver fluids during specific procedures.
