There is a common misconception that nails need to breathe and that gel manicures can cut off oxygen to nails. However, this is not true as nails are not living tissues and do not require oxygen to stay healthy. The only way oxygen can reach the nails is through the blood supply in the fingers and fingertips. While it is not necessary to let nails breathe, it is important to take proper care of natural nails and follow the correct steps for gel polish removal or infilling to prevent damage and weakness. Additionally, gel nail polish has been found to interfere with pulse oximetry readings, which are used to measure functional oxygen saturation in arterial blood. Therefore, it is recommended to remove gel nail polish before taking oximeter readings.

Nails are not living tissues and do not require oxygen
It is a common misconception that nails need to "breathe". Nails are not living tissues and do not require oxygen to stay healthy. The nail cells in the matrix get their oxygen from the blood, and no oxygen is absorbed from the outside world into the nail. Therefore, the idea that nails need to breathe is not supported by scientific evidence.
Nails are keratinous extensions that receive their nourishment internally, not via external air. The use of nail polishes and enhancements can offer numerous benefits, including protection, strength, and moisture retention. For example, regular use of strengthening polishes can gradually improve the overall condition and toughness of the nails. Additionally, nail polishes can help maintain the natural hydration levels of the nails, preventing excess water absorption and subsequent swelling and weakening of the nail structure.
It is important to note that while nails themselves do not require oxygen, proper nail care is crucial for maintaining healthy nails. This includes practices such as proper nail trimming and filing, as well as the use of quality products and proper application and removal techniques. For example, it is recommended to always wear gloves when doing household chores or working with chemicals to protect the nails and keep the skin healthy.
When it comes to gel nails specifically, it is not necessary to take a break from them as long as proper care is taken. Gel nails should be reapplied or infilled every 2 to 3 weeks, and it is important to follow the proper steps for removal or infilling to prevent damage to the nails. Additionally, it is recommended to apply cuticle oil daily and rehydrate the nails with a moisturizing product to maintain their health.
In summary, while nails are not living tissues and do not require oxygen, proper nail care and maintenance are crucial for keeping them healthy and strong. This includes practices such as regular hand care, the use of quality products, and proper nail care techniques.

Gel manicures can affect pulse oximetry readings
While it is true that nails are not living tissues and do not require oxygen to stay healthy, gel manicures can still affect pulse oximetry readings. Pulse oximetry is a standard monitoring technique of functional oxygen saturation (SpO2) in arterial blood. It is a simple, continuous, non-invasive, inexpensive, and reliable monitoring device that also provides heart rate measurements and an indication of tissue perfusion based on pulse amplitude.
The use of fingernail polish has been described to alter SpO2 readings, and its removal is commonly recommended before measurement. Gel-based manicures have become increasingly popular due to their attractiveness and longevity. However, the removal of gel nail polish requires a specialised procedure, which can be time-consuming and costly.
To evaluate the effect of gel manicures on pulse oximetry readings, a single-blind randomised controlled trial was conducted using 17 healthy female adult volunteers. The trial used two oximeters, the Philips M1191BL and Masimo SET®, with different technology and wavelength combinations. Results showed that light blue and orange gel nail polish colours resulted in a statistically significant increase from baseline SpO2 readings. Additionally, black and purple nail polish colours affected the precision of the readings on the Philips device more than other colours.
Therefore, gel manicures can result in overestimations of actual readings, which can delay the detection of hypoxaemia. In clinical, surgical, and emergency settings, gel nail polish should be routinely removed or an alternative monitoring technique used to ensure accurate SpO2 readings.

Proper removal of gel nail polish is important to prevent nail damage
While it is not true that gel nail polish cuts off oxygen to nails, proper removal of gel nail polish is still important to prevent nail damage. Nails are not living tissues and therefore do not require oxygen to stay healthy. However, incorrect removal methods can cause damage to your nails.
One should avoid picking, peeling, or filing off gel nail polish, as this can damage and weaken nails, causing breakage. Instead, follow proper removal steps to ensure your gel polish is safely and effectively removed.
To remove gel nail polish, first, apply a thin layer of petroleum jelly to each cuticle and the surrounding skin to protect your skin from the acetone. Then, cut cotton balls or strips to the size of each nail. Soak the cotton in acetone and apply them to your nails by wrapping small pieces of aluminum foil or plastic food wrap around your fingertips. This will ensure that only your nails come into contact with the acetone. After about 10-15 minutes, the nail polish should come off. Remove any remaining gel nail polish with a washcloth that you've run under warm water.
Another method is to use a gel nail polish remover. First, use a coarse nail file on the topcoat layer until it's not shiny and smooth anymore. Then, put a thick layer of gel polish remover on your gel nails. After about 5 minutes, use a metal cuticle pusher or an orangewood stick to gently remove the gel polish from each nail. Finally, clean your nails with a nail buffer and apply cuticle oil to rehydrate your cuticles.
Proper nail trimming and filing are also essential in maintaining healthy and strong nails. Be sure to trim your nails straight across and never on a curve. File them in one direction to prevent breakage.

Gel nail polish can be removed at home or by a professional
It is important to note that nails are not living tissues and do not require oxygen to stay healthy. Therefore, gel nail polishes do not cut off oxygen to nails.
While it is not necessary to take a break from gel nail polishes, it is important to take proper care of your nails in between applications. This includes applying cuticle oil daily, wearing gloves when cleaning or working with chemicals, and avoiding picking or peeling off gel polish.
If you wish to remove your gel nail polish, it can be done at home or by a professional. Removing gel nail polish at home can be done in several ways. One way is to soak your nails in really hot water for 5-6 minutes, which weakens the base coat, and then push it off with a cuticle pusher. Another way is to use acetone, which is the most effective way to remove gel nail polish at home. To do this, you can soak cotton balls in acetone and place them on your nails, wrapping them with foil or plastic food wrap. Leave this on for about 15 minutes, and then scrape off the excess polish. It is important to note that you should file the top layer of the gel polish before applying acetone, as it will not dissolve otherwise. You can also try buffing the first layer of polish lightly to enable the remover to work faster and more effectively. After removing the gel polish, remember to wash your nails, pat them dry, and apply a generous amount of moisturizer and cuticle oil.
If you prefer to have your gel nail polish removed by a professional, you can visit a nail salon or a manicurist. They will have the necessary tools and expertise to safely and effectively remove the gel polish. It is recommended to ask if their tools are sterilized and disinfected after each client to ensure proper hygiene and safety.

Nails should be cared for between gel manicures
While it is not necessary to let your nails breathe between gel manicures, as they are not living tissues and do not require oxygen to stay healthy, there are several steps you can take to care for your nails in between gel manicures.
Firstly, it is important to take a break from gel manicures and not have them reapplied or infilled more often than once every two to three weeks. This is because the process of putting on and taking off gel polish can be hard on your nails, and they need time to recover. During this break, try not to wear any nail polish at all, as this will allow your nails time to repair.
Additionally, you should always wear gloves when doing household chores or working in an environment where your hands are exposed to chemicals. This will protect both your nails and your skin.
You should also rehydrate your nails and cuticles by applying a moisturising product, such as petroleum jelly, several times a day. This will help to minimise brittleness and prevent your nails from chipping.
It is also important to never pick or peel off your gel polish, as this can damage and weaken your nails, causing breakage. Instead, make an appointment with your manicurist to have the polish removed, or follow proper removal steps at home.
Finally, be sure to trim and file your nails properly. Trim your nails straight across, never on a curve, and file them in one direction to prevent breakage. If you want a rounded nail shape, use a gentle buffer to smooth out the edges.
