With a press-on nail set that includes adhesive, the box usually contains a liquid cyanoacrylate-based glue, applied directly with the brush built into the tube. Alongside this classic glue, some sets come with double-sided adhesive tabs, pre-cut to the shape of the nail, while certain gel-look press-on tips attach with a gel adhesive that cures under a UV or LED lamp. The choice between the three depends on the type of set and how long you want the application to last, not on a one-size-fits-all formula for every press-on nail.
- Liquid cyanoacrylate-based glue is the option most often included in the box and dries in the air, without a lamp.
- Double-sided adhesive tabs come pre-cut to shape and are usually easier to remove when taking off the set.
- Gel adhesive is used with some gel-style tips and needs a UV or LED lamp to cure.
What types of adhesive are used for press-on nails
Liquid glue remains the most widely used option because it already comes in the box with most press-on sets and is applied directly with the brush built into the tube, in a thin layer on the natural nail and on the back of the press-on nail. It dries in the air within a few dozen seconds, without needing a lamp, which makes it the simplest option for a quick application at home. Double-sided adhesive tabs work differently: they come pre-cut to the shape of the nail, stick to the natural nail, and then the press-on nail is pressed on top, with no drying time. Gel adhesive is used with some gel-look press-on tips and cures under a UV or LED lamp, just like classic manicure gel (source: Artificial nails - Wikipedia), making it especially suitable for anyone who already has this type of lamp at home or goes to a salon for application.
What nail glue actually is
Chemically, liquid nail glue belongs to the same basic family as the household all-purpose glue known as super glue: ethyl cyanoacrylate (source: Cyanoacrylate - Wikipedia). The real difference between the two is not necessarily in the base molecule, but in how each is formulated, packaged, and accompanied by instructions: nail glue is designed as a cosmetic product, with a brush applicator sized for the nail area and directions for use on skin and nails, unlike a general-purpose household adhesive. The amount in the box, usually 2 g, is small but enough for a full application of an entire set of 24-30 nails.

Why household super glue is not a good choice for nails
Household super glue is not formulated, tested, or labeled for cosmetic contact with skin and nails, and its packaging does not include instructions for applying it to press-on nails. Its applicator and viscosity differ from those of nail glue: the nozzle on a household tube usually dispenses a larger amount that is harder to control than the fine brush on cosmetic nail glue, making it more difficult to keep the adhesive where you want it, away from the cuticle and surrounding skin. If skin does accidentally stick to cyanoacrylate, the best response is not to force it apart: the adhesive comes off on its own within a few days, while forcibly pulling it off can tear the skin (source: Cyanoacrylate - Wikipedia). For a more detailed analysis of this question, including exactly what happens when you replace nail glue with super glue, you can read the article dedicated to comparing super glue and nail glue.
How to reduce the risk of a reaction to adhesive
No cyanoacrylate-based adhesive can be called hypoallergenic or safe for everyone: sensitivity to cyanoacrylate fumes can develop gradually, even in someone who has worn these kinds of sets before without any problems. Approximately 5% of the population develop this kind of sensitivity after repeated exposure, with symptoms similar to a cold; this percentage refers to cumulative exposure to fumes, not a single instance of skin contact with the adhesive (source: Cyanoacrylate - Wikipedia). The U.S. Food and Drug Administration (FDA) notes more generally that infections and allergic reactions can occur with any type of nail product, regardless of the system or adhesive used (source: Nail Care Products - U.S. FDA).
An allergic contact reaction generally appears right at the site of exposure and becomes visible 24-48 hours after application (source: Allergic contact dermatitis - Wikipedia). For this reason, wearing a first set for just a few hours or a day shows you how your skin reacts before you wear a full set for up to three weeks. If you notice redness, itching, or stinging, remove the set and give your skin time to settle. If you genuinely suspect an adhesive allergy, the appropriate test is a patch test performed by a dermatologist: a clinical procedure in which 25-150 substances are applied to the back at the same time, unlike an informal trial at home on a single nail (source: Patch test - Wikipedia).
How to choose between glue, adhesive tabs, and gel adhesive
For most press-on sets, liquid glue is already included in the box, so you do not need to choose an adhesive separately before application. The real choice comes when you decide between glue and adhesive tabs for a particular set, or when you want a result that cures under a lamp. For a point-by-point comparison of glue and adhesive tabs, see this dedicated article detailing the differences in application and wear time, and for the exact steps for using adhesive tabs, follow the step-by-step guide to adhesive tabs. If your nails already hurt after a previous application, the article about the causes of discomfort from press-on nails explains what might be causing it, separately from the type of adhesive used.

Once you know which adhesive is already in the box and why it is not worth replacing it with household super glue, the choice is really about design and shape: length, nail shape, and shade.
