ArcticBlast vs Aspercreme: Which Topical Works Better? (2026 Comparison)
Quick answer: They suit different pain. Aspercreme with Lidocaine 4% numbs surface nerves, penetrating roughly 1-2 cm but lasting 4-6 hours, so it is the better choice for surface-level nerve pain such as post-shingles neuralgia and for anyone who wants fewer applications per day. ArcticBlast pairs DMSO with menthol and camphor to carry anti-inflammatory actives around 3-5 cm into joint, tendon and deep muscle tissue, acting in 3-7 minutes but lasting only 90-120 minutes. For most musculoskeletal pain ArcticBlast fits better, though DMSO is not FDA-approved for topical pain relief.
Aspercreme is one of the best-selling topical pain relievers in the US, available in lidocaine and trolamine salicylate (aspirin-like) formulas. ArcticBlast is a newer, DMSO-based product making different claims about penetration and relief duration. These two represent genuinely different approaches to pain management, and comparing them clarifies which fits which type of pain.
How Each Product Works
Aspercreme
Aspercreme comes in two main formulas with different mechanisms:
- Aspercreme with Lidocaine (4%): Lidocaine is a local anaesthetic that blocks sodium channels in sensory nerve fibres, reducing the transmission of pain signals. It numbs the area — which is effective but works at the nerve level rather than the inflammation source. Onset is 5–10 minutes; duration 4–6 hours (longer than most topicals). The trade-off is that it numbs rather than reduces inflammation — pain returns when the lidocaine wears off.
- Aspercreme Original (trolamine salicylate): A topical salicylate (aspirin derivative) that provides mild anti-inflammatory action. Penetration is limited — the salicylate doesn’t reach deep structures particularly well without a penetration enhancer.
ArcticBlast
ArcticBlast uses DMSO (dimethyl sulfoxide) as its carrier alongside menthol and camphor. DMSO isn’t a local anaesthetic — it doesn’t numb nerves. Instead, it drives active ingredients deeper into tissue than standard carriers, and has its own anti-inflammatory properties through hydroxyl radical scavenging. Relief comes from reducing inflammation at source rather than blocking the pain signal at the nerve.
Direct Comparison
| Category | Aspercreme (Lidocaine) | ArcticBlast (DMSO) |
|---|---|---|
| Primary mechanism | Local anaesthesia (nerve block) | Penetration + anti-inflammatory |
| Penetration depth | Superficial–moderate | Deep (3–5 cm with DMSO) |
| Onset | 5–10 min | 3–7 min |
| Duration | 4–6 hours (lidocaine) | 90–120 min |
| Addresses inflammation? | No (numbs signal only) | Yes (DMSO + actives) |
| Best for | Nerve pain, surface pain, longer-interval relief needed | Joint, deep muscle, tendon, arthritis |
| Odour | Minimal | Menthol + garlic (DMSO) |
| Skin sensitization risk | Low (lidocaine well-tolerated) | Low–moderate (DMSO) |
| Drug interactions | Systemic lidocaine risk with broken skin or large area | DMSO increases skin absorption of co-applied products |
When Aspercreme (Lidocaine) Is the Better Choice
- Nerve pain at the skin surface: Postherpetic neuralgia (post-shingles pain), minor surgical site discomfort, or surface-level neuropathic pain responds well to lidocaine’s nerve-blocking mechanism.
- Needing longer relief intervals: Aspercreme lidocaine’s 4–6 hour duration means fewer applications for patients managing pain through a work day or overnight without reapplication.
- Avoiding odour: ArcticBlast’s DMSO produces a garlic-like breath odour. Aspercreme is odourless, which matters in social or professional settings.
- Post-procedure skin sensitivity: For superficial wound-adjacent discomfort where you don’t want deep penetration, lidocaine’s surface action is precisely what’s needed.
When ArcticBlast Is the Better Choice
- Joint pain (arthritis, bursitis): Lidocaine blocks pain signals at the skin surface — it doesn’t reach joint capsules. ArcticBlast’s DMSO delivers anti-inflammatory actives into joint tissue. For arthritis, this is a fundamentally different and more effective approach.
- Tendinitis: Same logic — tendons sit below fascia. DMSO penetrates to peritendinous tissue; lidocaine does not.
- Deep muscle pain: Piriformis tension, paraspinal muscle spasm, deep hip flexor tightness — these require penetration past the superficial muscle layer.
- Addressing root cause vs masking: ArcticBlast’s anti-inflammatory mechanism works on the tissue causing pain. Lidocaine blocks the pain signal but leaves the inflammation source unchanged. For chronic conditions, reducing inflammation is more valuable than numbing.
How This Comparison Was Made
We have not run a head-to-head trial of these two products, and we would be sceptical of any affiliate site claiming to have done so properly. What follows is built from two things: what each product’s mechanism predicts, and the recurring themes in verified buyer reviews for both.
Worth stating plainly first: lidocaine is an FDA-approved over-the-counter topical anaesthetic with well-characterised behaviour. DMSO is not FDA-approved for topical pain relief in humans — its only human approval is intravesical instillation for interstitial cystitis. Claims about DMSO’s penetration depth come largely from laboratory and veterinary work rather than controlled human pain trials. That asymmetry in evidence quality matters more than any single comparison point below.
Joint pain and arthritis. Mechanistically, a surface anaesthetic should not reach a joint capsule sitting 2–5 cm down, and buyer reviews for Aspercreme lidocaine reflect that — praise concentrates on numbing, complaints on pain returning as it wears off. ArcticBlast reviewers more often describe reduced stiffness rather than numbness. Whether that reflects genuine deep delivery or the strong counter-irritant effect of menthol and camphor is not something buyer reviews can settle.
Tendon pain. Same reasoning, same caveat. Tendons sit below fascia, so depth matters in principle. Reviews for both products in this category are mixed, and tendinopathy responds to loading and rest in ways no topical addresses.
Surface nerve pain. This is the clearest case, and it favours Aspercreme. Postherpetic neuralgia involves sensitised nerve fibres near the skin surface, which is precisely what lidocaine acts on — and here the evidence is clinical rather than inferred. For this specific pain type we would point you to the lidocaine product rather than the one we earn commission on.
The Verdict
Aspercreme with Lidocaine is the better choice for surface-level nerve pain and situations where long relief duration between applications is the priority. ArcticBlast is better for any pain with a structural component — joint, tendon, deep muscle, or arthritis — where reaching the tissue source of inflammation matters. For most musculoskeletal pain (which describes the majority of people searching for topical pain relief), ArcticBlast’s penetration advantage delivers better real-world results despite the shorter duration per dose.

Frequently Asked Questions
Is ArcticBlast better than Aspercreme?
For joint pain, tendinitis, and deep muscle pain — yes. ArcticBlast’s DMSO penetrates to the tissue source of pain; Aspercreme’s lidocaine blocks pain signals at the nerve surface without reaching joint or tendon tissue. For surface-level nerve pain (like post-shingles), Aspercreme’s lidocaine formula is more effective.
Does Aspercreme’s lidocaine reach joints?
No. Lidocaine 4% in a standard cream carrier penetrates approximately 1–2 cm below the skin surface. Most joints sit at 2–5 cm depth. Aspercreme provides surface nerve blockade — it numbs the area above the joint — but doesn’t deliver anti-inflammatory action to the joint capsule itself.
Which lasts longer — Aspercreme or ArcticBlast?
Aspercreme lidocaine lasts significantly longer per dose (4–6 hours vs 90–120 minutes for ArcticBlast). If fewer applications per day is a priority, Aspercreme lidocaine wins on duration. If addressing inflammation and not just masking pain signals is the priority, ArcticBlast’s mechanism is more valuable despite requiring more frequent application.
Can I use Aspercreme and ArcticBlast together?
Not at the same time on the same area. DMSO in ArcticBlast significantly increases skin absorption of anything applied in the same location — including lidocaine, which can cause systemic side effects (heart rhythm, CNS effects) if absorbed in excess. Use one or the other, or apply to different body areas.
