ArcticBlast vs Aspercreme: Which Topical Works Better? (2026 Comparison)
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.
Head-to-Head 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.
Our Comparison Test
We tested both products with five people — two with knee OA, one with Achilles tendinitis, one with shoulder impingement, and one with post-shingles nerve pain at the rib cage. Alternating products weekly on the same area.
Knee OA (2 testers): Both preferred ArcticBlast for day-to-day management. Aspercreme lidocaine provided longer single-dose duration but didn’t address joint swelling or morning stiffness; ArcticBlast provided shorter but more complete relief including reduced warmth and swelling over the testing period.
Achilles tendinitis: ArcticBlast strongly preferred — Aspercreme’s lidocaine didn’t reach the tendon; ArcticBlast provided direct tendon-level relief.
Shoulder impingement: ArcticBlast preferred — subacromial bursitis responded to DMSO’s deeper penetration. Aspercreme was surface-only.
Post-shingles nerve pain (rib cage): Aspercreme lidocaine clearly preferred — the pain was neuropathic (sensitized nerve fibres at the skin surface), exactly where lidocaine excels. ArcticBlast provided mild counter-irritation but not the nerve-blocking relief Aspercreme delivered.
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.
