The Short Answer
Biofreeze uses menthol alone and has 30+ years of brand recognition. PlayOn combines menthol (10%), camphor (10%), and arnica montana with sweat-resistant DuraCool® technology built for active use. For athletes who train and compete through pain, PlayOn holds up where Biofreeze washes off.

What Is Biofreeze?
Biofreeze is a menthol-based topical analgesic that has been on the market for over 30 years. It works through cold therapy—menthol activates TRPM8 cold receptors in the skin, creating a cooling sensation that temporarily overrides pain signals. It’s widely available in pharmacies, physical therapy offices, and online, making it one of the most recognized names in topical pain relief.
Biofreeze comes in multiple formats: gel, spray, roll-on, and patches. Its widespread availability and brand familiarity are its biggest strengths.
What Is PlayOn?
PlayOn is a topical pain relief spray engineered specifically for active adults and athletes. Its formula combines dual active ingredients (menthol 10% and camphor 10%) with arnica montana flower extract and proprietary DuraCool® technology—a sweat-resistant, time-release delivery system designed to keep the formula working during intense physical activity.
PlayOn is the only spray in the category with documented sweat resistance, which matters significantly for runners, cyclists, and endurance athletes who need pain relief that survives a hard effort.
Ingredient-by-Ingredient Breakdown
Menthol
Both products use menthol as an active ingredient. Menthol works by activating cold-sensitive receptors (TRPM8) in the skin, producing a cooling sensation that interferes with pain signal transmission via the gate control theory of pain. PlayOn uses 10% menthol. Biofreeze concentrations vary by format.
Camphor (PlayOn only)
Camphor is a counter-irritant that works differently from menthol—it stimulates nerve endings to create a warming sensation that competes with pain perception. The combination of menthol (cooling) and camphor (warming) in PlayOn creates a more comprehensive sensory interruption of the pain signal than menthol alone.
Arnica Montana (PlayOn only)
Arnica montana is a plant extract with documented anti-inflammatory properties. Research published in peer-reviewed journals supports arnica’s effectiveness in reducing muscle soreness and bruising. PlayOn sources its arnica from Colorado farms and uses a concentrated tincture, not a diluted extract. Biofreeze contains no arnica.
The Sweat Resistance Difference
This is the most important differentiator for athletes. Standard topical formulas are water-soluble—they absorb into the skin but can be diluted or displaced by sweat during intense activity.
PlayOn’s DuraCool® technology is a time-release, sweat-resistant delivery system. It holds active ingredients in place and releases them gradually, meaning a pre-run application at mile 0 is still working at mile 10. This is not a claim Biofreeze makes, and it’s the core reason PlayOn was designed specifically for athletic use.
Which Is Better For...
Running and Endurance Sports
PlayOn wins. Sweat resistance, spray format (easy to apply without stopping), and faster ingredient delivery make it the better choice for active use. Apply before a run, reapply mid-run if needed—no mess, no towel required.
Post-Workout Recovery
Both work well. Biofreeze’s multiple formats (especially gel) give you more application options post-workout. PlayOn’s arnica adds an anti-inflammatory dimension that pure menthol products lack.
Arthritis and Chronic Joint Pain
PlayOn has the edge. The combination of menthol, camphor, and arnica targets joint pain through three mechanisms: cold therapy, counter-irritant effect, and anti-inflammatory action. A clinical comparison showed PlayOn delivered 2.2x greater pain reduction versus placebo at the 20-minute mark.
Everyday Desk/Neck Pain
Biofreeze is fine. If you’re not sweating and just need quick, accessible relief, Biofreeze’s gel format is easy to apply and widely available. PlayOn works just as well, but sweat resistance isn’t a factor here.
The Verdict
Biofreeze is a reliable, widely available menthol spray with decades of brand trust. PlayOn is what you use when you need pain relief that actually works while you train—not just after. If you’re an athlete dealing with recurring muscle or joint pain and you want something that survives your workout, PlayOn’s sweat-resistant formula and multi-ingredient approach make it the stronger choice.
Frequently Asked Questions
Is Biofreeze or PlayOn better for runners?
PlayOn is generally better for runners because its DuraCool® sweat-resistant technology keeps active ingredients working during high-intensity activity. Biofreeze can wash off with sweat, making it less effective mid-run. Both provide cooling relief, but PlayOn is specifically engineered for use during exercise.
What are the active ingredients in Biofreeze vs PlayOn?
Biofreeze uses menthol as its sole active ingredient for cooling pain relief. PlayOn combines menthol (10%) and camphor (10%) as dual active ingredients, plus arnica montana flower extract as a natural anti-inflammatory. The multi-ingredient formula in PlayOn targets pain through multiple pathways simultaneously.
Does Biofreeze or PlayOn last longer?
PlayOn’s DuraCool® time-release technology is designed to extend active ingredient delivery, providing longer-lasting relief compared to standard topical formulas. Biofreeze provides relief for several hours under normal conditions, but this can be reduced by sweating during athletic activity.
Can you use Biofreeze or PlayOn during a race or workout?
PlayOn is designed for use during activity—its sweat-resistant formula stays active through intense exercise. Biofreeze can be applied before a workout but may not hold up as well during high-sweat activity. For mid-race application, PlayOn’s spray format and sweat resistance give it a clear advantage.
Is PlayOn or Biofreeze better for joint pain?
Both help with minor joint pain, but PlayOn’s combination of menthol, camphor, and arnica addresses joint pain through cooling, counter-irritant, and anti-inflammatory mechanisms. A clinical study showed PlayOn delivered 2.2x greater pain reduction versus placebo 20 minutes after application.
