Acrylic and gel nails are two of the most popular nail services offered at salons. While both are great ways to try out new nail trends, there are some key differences between the two. Acrylic nails are made from a mixture of liquid monomer and powder polymer, which is applied to the natural nails and then moulded into the desired shape and length. On the other hand, gel nails are made from a liquid resin that is cured under UV or LED light. Gel nail polish can be applied on top of acrylic nails, and this can be done at home or at a salon.

What You'll Learn

Gel polish can be applied to acrylic nails
Yes, gel polish can be applied to acrylic nails. Acrylic nails are artificial nails or nail tips that are applied to your natural nails and filled in with an acrylic formulation. This formulation is a combination of liquid monomer and powder polymer, which creates a paste that bonds to your natural nails. This paste is painted onto the nail with a brush and is used to strengthen and shape the nail, and nail polish is usually painted on top to add colour.
Gel polish can be applied to natural nails, acrylics, and nail extensions, and the process is similar to applying traditional nail polish. Before a gel manicure, the nail artist will buff and wipe down your nails with alcohol to allow the polish to adhere better and help prevent lifting and peeling. The gel polish is then applied in the same way as regular polish. With each coat of polish, the nail is placed under a UV or LED light for between 30 seconds and two minutes to cure and dry. The final result is glossy, fresh-looking nails with a long-lasting finish.
There are many benefits to using gel nail polish, including the fact that it is easy to achieve and a great way to look put together for any event. You can choose from a range of colours and finishes, as well as an array of nail art, although there may be some limitations depending on the natural length of your nails. Gel polish is also a good option for those who want to change their nail polish at home, as it is easy to remove.
It is important to note that the UV nail lamps used to cure gel nail polish emit harmful UV rays, which can damage the skin on your hands and fingers. To mitigate this, you can apply sunscreen to your hands and fingers before your manicure or choose a gel polish that can be cured with an LED lamp, which emits less harmful light.

Acrylic nails are a mix of polymer and monomer
The chemistry behind the process involves the polymerisation of the monomer, which then surrounds each bead of the polymer powder. This creates an entanglement of polymer chains, with the chains wrapping around and encasing each polymer powder bead, fusing them into the acrylic nail. The powder works to stop cracks and reinforce the structure. The monomer liquid is composed mainly of ethyl methacrylate (EMA) and occasionally includes other monomers and additives. It has a purple tint due to the presence of UV inhibitors, which prevent the acrylic from yellowing.
The process of creating acrylic nails involves mixing the liquid monomer and powder polymer to form a paste. This paste is then applied to the natural nail using a brush, and it dries to form a hard, durable layer. The ratio of monomer liquid to polymer powder is crucial, as it affects the setting time and durability of the acrylic nails. If the ratio is too wet, it can slow down the setting time, and using fast-set acrylics with more initiator and/or catalyst can help speed up the process.
The application technique is also important to ensure the product doesn't run or dry too quickly. The brush should be carefully run through the powder until a small ball of powder forms at the end. This "pearl" is then placed on the desired part of the nail and spread across the nail tip. The product should be pressed into place without sticking to the brush or drying before bonding to the natural nail. After application, the nails are filed into the desired shape, and each nail can be painted with a base coat, nail polish colour, and a top coat.
Acrylic nails are a popular choice for those seeking long-lasting manicures, as they can last for 2-3 weeks. They offer freedom in terms of nail art, allowing for various lengths, shapes, and designs. However, it's important to note that removing acrylic nails requires soaking them in acetone for around 20 minutes, and improper use of UV lamps during the curing process can be harmful.

Gel nails are cured under UV or LED light
Gel nail polishes contain photoinitiators, a chemical that requires direct UV wavelengths to be hardened or 'cured'. This process is called curing. The two types of nail lamps used to cure gel nail polish are classified as either LED or UV. This refers to the type of bulbs inside the unit and the kind of light they emit.
LED lamps typically cost more than UV lamps, but they tend to last longer, and can cure gel polish faster. Not all gel polishes can be cured by an LED lamp, and some polishes are designed specifically for UV nail lamps. The wattage of an LED nail lamp does not indicate the UV intensity. UV intensity is the amount of UV energy that hits a surface.
UV nail lamps that cure gel nail polish emit harmful UV rays, which can damage the skin on your hands and fingers. However, it has been proven that UV exposure will cause minimal to no damage to your client's skin. If you are in any doubt, it is best to stick to LED lamps as they do not use any UV light and therefore pose no risk.
To avoid under-curing or over-curing, it would be helpful for UV nail lamp manufacturers to indicate on the label the UV watts intensity at 400, 390, and 380 nm. With this information, users can ensure they are using the correct LED nail lamps to cure their gel polish. The thicker the applied layer, the more difficult it will be to achieve proper curing since the upper layers will absorb most of the UV, leaving the lower layers under-cured. Two thinner layers will cure much better than one thick layer, as long as each layer is exposed to the correct intensity of UV wavelengths for the time indicated in the product directions.

Acrylic nails cure when they come into contact with air
Acrylic nails are a popular nail enhancement option. They are formed from a mix of monomer and polymer, which creates a gummy paste that is then painted onto the nail with a brush. This paste is then shaped and left to air dry and harden. The curing time for acrylic nails depends on the temperature of the product—the warmer the liquid and powder, the faster the curing time. Conversely, cooler products will take longer to cure. Typically, acrylic nails will air dry in around 15-30 minutes.
Acrylic nails are a more durable option than gel nails, which are cured under a UV light. However, gel nails are easier to remove than acrylics, which must be soaked in acetone for 20 minutes to be removed. Acrylic nails can be prone to bubbling, which can be caused by the product being too wet or too dry, or by air bubbles being whipped into the liquid by brushes.
Acrylic nails can be long-lasting, with a set typically lasting between three to eight weeks. However, they do require maintenance every two to three weeks, which can be time-consuming and costly. Proper maintenance is essential to prevent damage to the natural nail, which can include breaking, cracking, and peeling. To prevent this, it is recommended to moisturize the hands and nails with cuticle oil, take nail-boosting supplements, and keep up with regular nail appointments.
While some sources claim that nails need to "breathe" between polishes, this is a myth. Nails get oxygen from the blood, not the air, so acrylic nails can be worn for extended periods without affecting oxygen or nutrient flow to the nails. However, nail discolouration, peeling, ridges, splits, keratin granulation, and cuticle dehydration can indicate that it is time to take a break from acrylics.

Gel nails are more flexible and less prone to chipping than acrylics
Gel nails and acrylic nails are two of the most popular salon nail services. While they may appear similar, there are some key differences between them.
Gel nails are more flexible than acrylic nails, making them feel lighter and more comfortable. This flexibility, however, means that gel nails are not as strong as acrylics and are more prone to chipping, especially if you use your hands a lot. This is because gel nails are applied using a gel-based polish that is cured under a UV lamp. The resulting nails are shiny and look natural, and the gel polish is typically more flexible than acrylic.
The flexibility of gel nails also makes them less resistant to breaking. However, they are also known for being easy to remove and less likely to cause damage to natural nails. The removal process for gel nails does not require soaking in acetone like acrylic nails do. Instead, a cotton ball soaked in acetone nail polish remover is placed on the nail, which is then wrapped in aluminium foil for 20 minutes.
Acrylic nails, on the other hand, are made from a combination of liquid monomer and powder polymer. This mixture creates a hard, protective shell that can prevent weak, brittle nails from breaking. Acrylic nails are applied by painting the natural nail with this mixture, which then hardens and forms a durable layer over the natural nails.
While both types of nails can be prone to cracking or chipping if not properly maintained, gel nails are generally less prone to chipping than acrylics due to their flexibility.
