Shellac vs Gel vs BIAB vs Acrylic vs SNS
Which Nail System Is Right for You? — Australia Guide
• Shellac (branded hybrid): gentle, natural look, lasts 2–3 weeks. Best for natural nails.
• Gel Polish: durable, chip-resistant, high shine. Lasts 2–4 weeks. Best for low-maintenance wear.
• BIAB (Builder in a Bottle): strengthens weak nails, adds structure. Lasts 3–5 weeks. Best for peeling or brittle nails.
• Acrylic: very strong, ideal for extensions. Lasts 3–6 weeks. Best for dramatic length.
• SNS Dip Powder: lightweight, no lamp needed. Lasts 3–4 weeks. Best for those who prefer to avoid UV/LED lamps.

For Australian women doing their nails at home — or deciding what to ask for at a salon — the number of options can feel confusing. Shellac, Gel, BIAB, Acrylic, SNS. Each system has different strengths, removal processes, and impacts on nail health.
This guide breaks down each option clearly so you can choose the right system for your nails, lifestyle and budget.
| Type | Best For | Longevity | Removal | Damage Risk | Lamp Required? |
|---|---|---|---|---|---|
| Shellac | Natural look & shine | 2–3 weeks | Easy acetone soak-off | Low | Yes (UV/LED) |
| Gel Polish | Durability with natural feel | 2–4 weeks | Easy acetone soak-off | Low | Yes (UV/LED) |
| BIAB | Strengthening weak nails | 3–5 weeks | Acetone soak-off | Very low | Yes (LED/UV) |
| Acrylic | Length & extensions | 3–6 weeks | File + soak (harder) | High | No (air dry) |
| SNS Dip | Lightweight durability | 3–4 weeks | Acetone soak-off | Medium | No |
Shellac is a brand name by Creative Nail Design (CND) — not a generic nail type. It is a hybrid system that combines the ease of regular polish with the durability of gel. When people say "shellac nails" they typically mean any cured gel polish, but technically Shellac is a specific CND product.
Who it is for. Anyone wanting a long-lasting, glossy manicure on natural nails with minimal damage risk.
Gel polish is the broad category that includes any nail polish requiring UV/LED curing — including Shellac. Unlike regular polish, gel is cured under a lamp for a chip-resistant, high-gloss finish that lasts weeks.
Who it is for. Almost everyone. The go-to for long-lasting, low-maintenance manicures on natural nails — including at-home use.
BIAB (Builder In A Bottle) is a thicker structural gel designed to add strength and length to natural nails. Unlike regular gel polish, BIAB builds a protective layer over the nail that repairs damage and prevents breakage over time.
Who it is for. Women with weak, peeling, thin or damaged nails who want to strengthen them at home without salon visits or harsh chemicals.
Acrylic nails combine liquid monomer and powder polymer that hardens in air. It is the traditional salon system for dramatic nail extensions and is still widely used for its unmatched strength.
Who it is for. Anyone wanting significant nail length extensions or very strong reinforcement. Best done at a salon — not recommended for at-home beginners.
SNS (Signature Nail Systems) is a brand name for dip powder nails — nails are dipped into coloured acrylic powder and sealed with activator liquid. No UV/LED lamp required.
Who it is for. Someone who wants acrylic-like durability in a lighter form and prefers to avoid UV/LED lamp exposure.
Choose Shellac or Gel Polish if...
You love your natural nail length and want a flawless, chip-resistant colour that lasts 2–4 weeks. Both offer beautiful results with minimal damage when properly applied and removed. For at-home use in Australia, Ambedo Solid Gel is the simplest and most mess-free option.
Choose BIAB if...
Your nails are weak, peeling, thin or damaged and you want to strengthen them while still having colour. BIAB is the perfect middle ground between regular gel and acrylics — and one of the safest at-home options available. Ambedo Fibre Fix BIAB ships Australia-wide.
Choose Acrylic if...
You want to add dramatic length via extensions. Best done at a professional salon — not recommended for at-home beginners due to the chemical fumes and damage risk from incorrect removal.
Choose SNS Dip Powder if...
You want durable, lightweight nails without UV/LED exposure, and you are not sensitive to powder dust. Best done at a salon for hygiene reasons.
Which is more durable — gel polish or acrylic?
Acrylic is stronger and better for extensions. However, gel polish offers excellent chip resistance for natural nails and is far more flexible, reducing the risk of snapping your natural nail. For most women doing their nails at home, gel or BIAB is the better choice.
Can I apply BIAB over gel polish?
BIAB is designed to be applied directly to the natural nail as a base and builder. You can apply gel polish colour on top of cured BIAB for colour, but not the other way around. Ambedo's Fibre Fix is a 5-in-1 — it replaces your base coat, so you apply it first, then add colour on top if desired.
Is SNS dip powder safer than gel?
It depends on your sensitivity. SNS avoids UV/LED exposure but can cause irritation from powder dust in some people. Gel has UV curing but fewer airborne particles. For the safest gel option, choose a HEMA-free formula like Ambedo — HEMA is the most common gel nail allergen.
How do I remove BIAB at home without damaging nails?
Lightly file off the shiny top coat to break the seal. Soak cotton pads in acetone, place on nails, wrap with foil, and wait 10–15 minutes. Gently slide off the softened gel with a wooden cuticle stick. Never peel or force removal — that is what causes nail damage.
What is the difference between Shellac and regular gel polish?
Shellac is a specific CND brand product — thinner and closer to traditional nail polish but cured under a lamp. Regular gel polish is the broader category, often thicker and longer-lasting. Both are cured under UV/LED and removed with acetone. For most people the difference is minimal in terms of wear.
Can I do gel nails at home in Australia without a professional lamp?
Yes — all Ambedo starter kits include a 36W LED lamp. You do not need to buy one separately. The lamp is compatible with all Ambedo gel systems — Solid Gel, BIAB and Speedi Mani. View all starter kits →

Individual results may vary. Always follow manufacturer instructions for best results. Store gel products away from direct sunlight — sunlight contains UV that will cure your gel prematurely.
