“Does it actually work?” is the fair, obvious question — and the one most X39 pages quietly dodge. I’m not going to make claims I can’t stand behind, and I’m not going to hand you a wall of testimonials and call it proof. Instead I’ll tell you what the patch is described as doing, why it’s hard to evaluate, and how to think about it if you’re sceptical — which is the healthy starting position.
I’m Dave Prosser, founder of Simply Younger and an authorised LifeWave Brand Partner. I have a financial interest in the product, so don’t take my word for anything — weigh it accordingly.
Key Takeaways
- X39 is a non-transdermal, general-wellness phototherapy patch that gently stimulates the skin with light to support the body’s natural energy flow for strength and stamina.
- It’s not a medicine and makes no cure, treat or prevent claims.
- Personal experiences — including mine — can’t prove an effect.
- How you feel is shaped far more by sleep, training and food.
- It’s an add-on to fundamentals, not a replacement.
- Buy only from an authorised Brand Partner store to get genuine product.
What is X39 actually designed to do?
Let’s be precise. X39 is a non-transdermal, general-wellness phototherapy patch that gently stimulates the skin with light to support the body’s natural energy flow for strength and stamina. That is the description — no more, no less. It is not a drug, it is not a stem cell product, and it does not cure, treat or prevent anything. Any page telling you a patch will fix a medical condition or reverse ageing is a page to be wary of.
Why is X39 hard to evaluate?
Because how you feel day to day is noisy. Sleep, stress, training load, food and caffeine all move the needle. On top of that, expectation and placebo are powerful, and changing several things at once makes it impossible to isolate cause. That’s why individual stories — good or bad — aren’t evidence that a product works.

How should a sceptic think about it?
Be clear about what you’re buying: a general-wellness habit, not a treatment. Keep your expectations at LifeWave’s description and nothing more. Keep measuring the things that matter — I use a monthly Hume Body Pod scan and WHOOP to track my body composition and recovery — but recognise that self-tracking while changing other habits can’t tell you what caused what. And if you have a health concern, see your doctor rather than looking for a patch.
What should you not expect from X39?
Don’t expect it to fix poor sleep, replace training, or make up for a bad diet. It is not a lever that overrides your fundamentals. My own routine — lifting every second day, 10,000+ steps, cold plunge, sauna and steam most days — is where the work happens. X39 is a separate daily habit on top.
Is X39 worth trying if you’re sceptical?
That’s your call, and scepticism is the right posture either way. If you do try it, buy genuine product from an authorised store and judge it as what it is: a general-wellness patch.
