Nail dehydrators help remove moisture from the nail bed
Nail dehydrators are an essential tool for any nail technician. They are used to remove moisture from the nail bed and create a consistent, even base for the gel polish to adhere to. This helps to prevent bubbling, lifting, and chipping, ensuring a long-lasting manicure.
Nail dehydrators are available in both liquid and powder forms and typically contain active ingredients such as acetone, isopropyl alcohol, propylene glycol, alpha-hydroxy acid, vitamin E, aloe vera extract, or tea tree oil. These ingredients serve various purposes, from fighting bacteria to nourishing nails to prevent breakage.
To use a nail dehydrator, simply apply it with a nail polish brush onto clean, dry nails before polishing or applying gel. Allow the product to air dry until it becomes clear, and then proceed with your gel polish application. This process helps create a strong bond between the gel polish and the nail, promoting better adhesion and longer-lasting results.
While nail dehydrators are not mandatory when applying gel polish, they offer significant benefits. They increase the longevity of your manicure, reduce the risk of chipping and lifting, and help create a more consistent and appealing finish. Additionally, nail dehydrators can help prevent bacterial growth by eliminating excess water that can accumulate between layers of polish or tissue paper used during the application process.

Dehydrators are not essential but can increase manicure longevity
Dehydrators and primers are not essential for gel manicures, but they can help your manicure last longer. Dehydrators remove moisture from the surface of the nail, creating an even base for the gel polish to adhere to. This helps to prevent bubbling, lifting, and chipping. They are especially useful if you want to create more complex designs.
Dehydrators are available in liquid and powder forms and contain different active ingredients, such as acetone, isopropyl alcohol, propylene glycol, vitamin E, aloe vera extract, or tea tree oil. Each ingredient serves a different purpose, such as fighting bacteria or nourishing the nails to prevent breakage. To use a dehydrator, simply apply it with a nail polish brush onto clean, dry nails, and let it air dry until clear before proceeding with your gel polish.
Primers are another product that can be used to help gel manicures last longer. They create an even surface on the nails and help them bond with the gel polish. Primers also remove any remaining oils and grease on the nail plate, which can otherwise cause the base coat not to adhere properly and create air bubbles. There are two types of primers: acid-based and acid-free. Acid-based primers use methacrylic acid to create microscopic tears and holes on your nail bed, allowing the gel polish to grip onto your nails better. When used in small amounts and not too frequently, acid-based primers are safe. However, if used incorrectly and too often, they can weaken your natural nails over time. Therefore, most experts recommend using non-acid-based primers.
If you are happy with the longevity of your gel manicures and do not struggle with chipping or lifting, you may not need to add the extra step of using a dehydrator or primer. However, if you are looking for ways to make your gel manicures last longer, these products can be beneficial.

Nail primers are not necessary but can help gel polish adhere
Nail primers are not necessary, but they can help gel polish adhere better and last longer without chipping. A primer is designed to create an even surface on your nails and help them bond with base coats, gels, or acrylics. It etches the nail plate to help the gel polish stick to the nail.
There are two types of nail primers: acid-free and acid. Acid-free primer is the most commonly used primer, with a gentle formula that helps with adhesion. It is great for those who struggle with chipping, lifting, or peeling with gel manicures. Acid-free primer removes oils from the nail plate, which can prevent the base coat from adhering properly and cause air bubbles.
Acid primer is a stronger substance that can be helpful for people with problematic nail plates or anyone who may suffer from hormone problems or is on specific medications that affect their nails. It can also be used for infilling, but only on the natural nail plate.
Nail dehydrators are another product that can be used to help gel polish adhere. Dehydrators remove moisture from the nail bed, creating a more even base for the polish to stick to and helping to prevent chipping, lifting, and bacterial growth. Dehydrators can be used in conjunction with primers to help promote adhesion.

Acid-based primers weaken natural nails over time
Dehydrating the nail is an important step in gel manicures as it removes moisture from the nail bed, creating a lasting, durable manicure and a strong bond between the nail polish and the nails. Dehydrators are available in liquid and powder forms and come with different active ingredients such as acetone, isopropyl alcohol, propylene glycol, vitamin E, aloe vera extract, or tea tree oil.
Nail primers are another product that helps prepare the nail before gel polish application. There are two types of nail primers: acid-based and acid-free. Acid-based primers, which contain methacrylic acid, can be corrosive to the skin around the nail. While the nail plate is composed primarily of keratin, a protein that is less reactive to acids compared to skin tissue, prolonged or repeated exposure to acid-based primers could potentially weaken and dehydrate the nail plate over time, leading to issues such as brittleness. This is especially true when these primers are used alongside other products with high adhesion, regular acetone soak-offs, or incorrect removal.
Acid-based primers act as a bonding element for the base coat and create a stronger substance that etches the nail plate to help the gel polish stick to the nail. They are often used by people who struggle with chips or lifting in their gel manicures. However, applying too much primer can also affect the strength of the adhesion, and over-priming with an acid-based primer can lead to chemical nail damage and eventually thin the nail plate.
Acid-free primers, on the other hand, are the most commonly used primers due to their gentle formula that aids in adhesion. They act like double-sided sticky tape, creating a temporary change in the pH of the natural nail to make it more alkaline, which helps the product adhere.

Primer and dehydrator products should be used with caution
While primer and dehydrator products can be beneficial in preparing your nails for gel polish, it is important to exercise caution when using them. Here are some key considerations:
Firstly, primer and dehydrator products are not suitable for everyone. If you have sensitive skin or are prone to allergies, it is crucial to perform a skin test before each use, as these products can sometimes cause allergic reactions. Additionally, if your nails are damaged or infected, it is recommended to avoid applying gel polish altogether until the nails have healed.
Secondly, these products should be used sparingly and only when necessary. If your gel manicure already lasts for more than two weeks without chipping or lifting, adding an extra step with a primer or dehydrator may not be needed. Overusing these products can potentially lead to excessive drying of the nails, making them brittle and more prone to breakage.
Thirdly, it is essential to follow the instructions carefully when using primers and dehydrators. For example, when applying an acid primer, it is important to let it fully evaporate before continuing with the manicure. Using too much product or not allowing it to dry properly can impact the adhesion of the gel polish and may lead to suboptimal results.
Furthermore, when using a nail dehydrator, it is crucial to choose a product specifically designed for nail care. Avoid using substances like pure alcohol or acetone as they can damage the delicate keratin layers of the nails and cause skin irritation. Instead, opt for commercial nail dehydrators with ingredients like acetone, alpha hydroxy acid, vitamin E, or tea tree oil, which can help nourish and protect the nails while also promoting adhesion.
Lastly, while primer and dehydrator products can enhance the adhesion of gel polish, they are not always necessary. Proper nail preparation, such as ensuring your nails are clean, dry, and free of oils, is often sufficient to achieve good adhesion. Additionally, using a bonder product specifically designed to raise the pH of the natural nail can also improve adhesion without the need for a primer or dehydrator.
