If you have ever gone through an ultrasound, you must have experienced the cold, gooey, and sticky sensation of the ultrasound gel. The gel acts as a conductive medium by reducing airspace between the patient’s skin and the ultrasound transducer. It is necessary to produce the best results for the scan. This gel is used in ultrasound diagnostics, ultrasound therapies, laser procedures, and cosmetic treatment.
In this article, we have listed the top 10 ultrasound gels. But before we get to the list, let’s look at what an ultrasound gel is and why it is used.
What Is An Ultrasound Gel?
The ultrasound gel is a water-based hypoallergenic gel that is used in all types of ultrasound scans. It can also be used with cavitation machines. The gel is specially formulated to act as a coupling agent and reduce static while using ultrasound equipment.
The ultrasound gel is made of water and propylene glycol. Propylene glycol is a synthetic compound that is found in food and cosmetics or hygiene products. The sticky consistency of the gel allows it to spread over the patient’s skin without dripping or running.
The tiny hair and dry skin hold many little pockets of air, and sound waves don’t travel through the air very well. The gel becomes a necessity as it serves as a connector and establishes a bond between your skin and the ultrasound probe by eliminating the air. It helps the sound waves travel directly to the tissues beneath the skin of the patient, allowing to get a clear image of the organ(s) of interest.
Ultrasound gel has a purpose to serve during the scan and is applied to your skin for better scan results. Here are a few reasons the gel is a necessity during scans.
Advantages Of Ultrasound Gel
- Provides optimal contact between the ultrasonic head and the skin.
- Reduces or eliminates static energy
- Eliminates air between the transducer and the skin.
- Provides superior transmission of ultrasound waves.
- Contains thickening agent to improve the spreadability on the skin.
- Easily removable after treatment without leaving any residues.
- The gliding properties of the gel help the ultrasonic head subtly glide over the skin.
- Doesn’t stain clothes even if carelessly handled.
- This gel is acoustically correct for the broad range of frequencies used.

Ultrasound gels can be used for varied purposes. However, we advise you to read the product description before you use it for any other intended purpose. The above lists featured the best-reviewed and used ultrasound gels on the market.
Ultrasound scan is considered to be a safe radiological procedure. Though adverse skin reactions with doppler ultrasound are uncommon and rare, a few cases have been reported. A small population of people developed contact dermatitis when exposed to ultrasound gel. The study concluded that the purpuric reactions occurred as a result of phenoxyethanol and paraben mixing and causing irritation to the skin (1). We have listed a few more side effects of ultrasound gel below.
Ultrasound Gel Side Effects
- Ultrasound gels can leave behind a sticky and greasy residue, causing drying of the skin or flaking.
- Bacterial contamination
Let’s now look at the difference between ultrasound, ECG, and IPL gels.
Difference Between Ultrasound Gel, Electrocardiography Gel, And IPL Gel
The electrocardiography (ECG) gel has the same viscosity as the ultrasound gel. The main underlying difference between ECG gel and ultrasound and laser gels is that the electrocardiography gel contains an additional component that enables it to transmit electro activity via a person’s skin. This is done with the help of electrodes. The current is then transmitted into the ECG device for recording.
The IPL gel has more viscosity than the ultrasound gel, which helps to disperse and minimize the heat produced by the laser or IPL equipment. The laser gel provides much more favorable results of refraction of light when passed through it when compared with other gels.

Expert’s Answers For Readers’ Questions
What is ultrasound gel made of?
Ultrasound gel is a thick transparent substance. Several companies make it out of various combinations of water, propylene glycol, glycerine, perfume, dyes, phenoxyethanol, or carbopol R 940 polymer. The information about the ultrasound gel is hard to find, but you are most likely to find it in the material data safety sheets of the various companies that make it.
How long does ultrasound gel last?
The manufacturers mention that the shelf life of the ultrasound gel is 5 years. However, it is advisable that once the bottle is open, you should mark it with an expiration of 28 days. The rationale behind this recommendation is that this gel is used by multiple people and multiple times. Thus, there is no way to ensure that the gel is not contaminated. Ensure that only sterile gels are being used for procedures involving vaginal or esophageal transducers, biopsy, etc. The sterile gel is only for one-time use.
What can be used as a substitute for an ultrasound gel?
While the ultrasound gel is a specialized formulation used during the procedure, there are many substitutes that serve the same purpose, like KV jelly, Bio-oil, moisturizers, and creams, hand sanitizer, skin gel, or aloe vera.
Is it safe to use ultrasound gel substitutes?
Medical grade ultrasound gel is costly. Hence, many consumers and clinicians resort to alternatives. However, these gel substitutes come with some risk. They might give unreliable diagnostic results, cause skin irritation or allergies, and even damage the machine. Coupling agents are specialized ultrasound supplies. The conductive gel has been formulated keeping in mind the needs of the procedure.
