SNS vs Shellac: 7 Clear Differences & Your Right Choice

Q: Does SNS last longer than Shellac?

Yes , SNS generally lasts longer than Shellac, but the exact duration depends on nail condition, technician skill, and aftercare. Shellac is engineered for around 10–14 days of glossy wear, making it perfect for those who like a fortnightly refresh. In contrast, SNS creates a stronger, thicker coating that often endures 2–4 weeks or more without significant chipping. This makes it attractive to clients who cannot visit the salon as frequently. However, lifestyle factors—such as frequent typing, exposure to cleaning products, or nail-picking habits—can shorten the lifespan of both systems. In practice, SNS provides longer wear, but Shellac delivers more predictable removal and less bulk.

Q: Does SNS use UV/LED light?

No , SNS dip powder nails do not require any LED or UV curing. The system uses an activator that hardens the powder layers in natural air, eliminating the need for lamp curing. This is often preferred by clients who are concerned about UV exposure on their hands. That said, it is important to note that SNS also manufactures gel-based products (such as GelStar™) that do require lamp curing, but these are separate from the standard dip-powder service. For classic SNS dip manicures, no UV/LED lamp is needed, making it distinct from Shellac, which always requires curing under an LED or UV light.

Q: Is Shellac just gel by another name?

No , Shellac is not a generic term for gel polish—it is the proprietary hybrid gel-polish system developed by CND®. What makes Shellac unique is its patented formulation designed to soak off easily without aggressive filing. Unlike traditional gels, which may require buffing or drilling, Shellac releases when wrapped in acetone properly. This sets it apart in both safety and client convenience. While the word “Shellac” is sometimes incorrectly used to refer to any gel-polish, the true Shellac system is only available through CND and trained technicians. Its identity as a brand is essential in differentiating it from generic gel systems.

Q: Which is better for thin or bendy nails?

SNS is generally better suited for thin or bendy nails because its thicker acrylic powder coating adds structural reinforcement. Clients with naturally weak nails often find that SNS provides more protection against splits and breaks. Shellac, while durable, is applied in a thinner layer that behaves more like traditional polish. For those who want strength, SNS offers a sturdier option. However, Shellac may still be chosen by clients who prefer a lighter feel or who book regular two-week maintenance. The decision comes down to whether nail strength or a natural, lightweight finish is the top priority.

Q: Is dip powder sanitary?

Yes , dip powder can be sanitary when applied using professional protocols. The concern arises when salons allow multiple clients to dip their nails directly into a shared powder jar. This practice can transfer bacteria or contaminants. High-standard salons prevent this by pouring or sprinkling powder into a separate, single-use container for each client. At J.Aesthetic, hygiene protocols ensure no double-dipping occurs, making SNS a safe and professional service. As long as these best practices are followed, dip powder is as hygienic as gel-polish systems like Shellac.

When comparing SNS nails (dip powder) and Shellac nails (CND’s hybrid gel-polish), the differences go beyond branding.

Each system has distinct application methods, curing processes, longevity, removal techniques, cost considerations, and suitability for different nail conditions.

SNS is known for its thicker, stronger dip-powder overlay that can last several weeks, while Shellac offers a lighter, high-gloss gel-polish finish designed for easy soak-off after two weeks.

Understanding these distinctions helps clients choose the right service for their lifestyle, preferences, and aftercare habits.

What Is Shellac?

Shellac is the proprietary hybrid gel-polish system developed by CND®. It combines the flexibility of polish with the durability of gel. The system applies in layers—base, colour, and top coat—each cured under an LED/UV lamp for instant hardness and shine. The result is a lightweight, glossy coating that feels similar to traditional nail polish but resists chips for up to two weeks.

What makes Shellac distinct is its engineered soak-off design.

When wrapped in acetone and removed by a trained professional, the product releases cleanly without the need for heavy filing. This makes Shellac particularly appealing for clients who value minimal damage during removal and prefer to refresh their manicure every fortnight.

Its smooth, thin finish is popular among those who want a refined, natural-looking manicure with reliable shine.

What Is SNS?

SNS refers to a dip powder nail system that layers a bonding base with coloured acrylic powder. The powder is brushed or sprinkled over the nail, then sealed with an activator that hardens the surface—no UV or LED lamp required. The finished effect is thicker and more supportive than gel-polish, making SNS a common choice for clients with brittle or shorter nails.

In terms of wear, SNS is recognised for lasting between two to four weeks when properly applied and maintained.

The extra thickness provides structural support, but removal can be more time-consuming than Shellac.

Salons must soak nails in acetone for an extended period, then carefully refine the surface to avoid stress on the natural nail.

A key consideration is hygiene: reputable salons avoid “double-dipping” into communal jars, instead using pour-over or sprinkle methods for a sanitary application.

SNS vs Shellac: Side-by-Side Comparison

After understanding each system individually, the clearest way to see the differences is to compare them directly.

The following table highlights how Shellac and SNS perform across the factors that matter most to clients in Australia.

Factor	Shellac (CND)	SNS (Dip Powder)
Definition	Hybrid gel-polish brand by CND®	Acrylic dip-powder system
Curing	Requires LED/UV light	No lamp; activator cures in air
Look & Feel	Thin, glossy, natural polish-like finish	Thicker, stronger, more supportive
Wear Duration	~10–14 days	~2–4+ weeks
Removal	Acetone soak-off, engineered for clean release	Longer acetone soak, careful filing required
Hygiene	Standard polish/gel hygiene	Best practice: pour or sprinkle powder
Best For	Clients who want easy soak-off and fortnightly refresh	Clients needing strength and longer gaps between appointments

Choosing Between SNS and Shellac by Goal

Selecting between SNS and Shellac depends on personal priorities, lifestyle, and nail health goals.

Each system provides different benefits, and the right choice varies by what the client values most.

For a high-gloss, lightweight finish with easy removal: Shellac is the better choice, especially for those who book regular two-week appointments and prefer a natural, polish-like look.
For stronger reinforcement and longer wear between salon visits: SNS offers a thicker overlay that adds structural support, making it ideal for clients with softer or break-prone nails.
For minimising UV exposure: SNS requires no lamp curing. Shellac uses LED/UV curing, though many salons provide protective gloves or recommend applying sunscreen on hands.

Pro Aftercare That Extends Wear (Regardless of System)

Even the best nail system needs proper care to achieve maximum longevity. Clients who follow simple aftercare practices often see their manicures last significantly longer without lifting, peeling, or breakage. Good aftercare also ensures the natural nail remains healthy underneath the coating.

Daily hydration: Applying cuticle oil keeps the coating flexible and reduces the risk of micro-cracks.
Protective habits: Wearing gloves during cleaning, gardening, or dishwashing prevents premature breakdown, especially for Shellac coatings.
Avoid peeling or prying: Attempting to peel off Shellac or SNS can strip layers of the natural nail, weakening future applications.
Book professional removal: Allowing technicians to handle soak-off ensures minimal damage and maintains nail integrity.

As long as these best practices are followed, dip powder is as hygienic as gel-polish systems like Shellac.

Which removes more gently?

Shellac is generally considered the gentler option for removal. Its formula was specifically designed to release during an acetone soak without the need for harsh filing. This allows technicians to remove Shellac efficiently with minimal impact on the natural nail. SNS, on the other hand, often requires a longer soak and more refinement, which, if rushed or handled improperly, can cause stress to the nail surface. The key factor is not the system itself but whether removal is done patiently and professionally. Clients who prioritise gentle removal may prefer Shellac, but both systems can be safe when removed by trained technicians.

Will either damage nails?

Neither Shellac nor SNS inherently damages nails when applied and removed correctly. Nail damage typically occurs due to poor preparation, rushed filing, or at-home peeling and picking. Shellac’s soak-off design reduces the risk of damage, while SNS offers added strength but requires careful removal. With both systems, nail health is preserved through proper salon technique and consistent aftercare, such as regular cuticle oil application and avoiding manual peeling. At J.Aesthetic, trained professionals follow protocols that protect natural nails, ensuring that either service remains a safe and stylish option.
