How to use Penetrex Balm: five simple steps to a fresher evening
Clean and dry the skin, take the amount you need, spread it over the area, press lightly and repeat once or twice a day. The whole thing takes about a minute.

The five steps of Penetrex Balm application
Clean and dry
Wash the skin over the area of discomfort and dry it well.
Take the amount you need
Squeeze out the quantity you need from the tube. A thin layer is enough.
Apply directly
Spread the balm directly over the area of discomfort.
Press lightly
Gently press the balm onto the skin so that it settles and stays in place.
Once or twice a day
Use it once or twice a day, depending on how strong the discomfort feels.
What does each of the five steps involve?
Step 1, clean and dry. Wash the skin over the area with water and a mild soap, then pat it dry with a clean towel. A clean surface lets the balm spread evenly, and a dry surface helps it settle. After a bath or shower is the ideal moment, because the skin is clean and you are already relaxed.
Step 2, take the amount you need. Squeeze the tube gently. You decide the amount, and you will soon learn what covers a knee, a shoulder or a calf. The rule of thumb is that less is more: it is easier to add a little than to wipe a lot away.
Step 3, apply directly. Spread the balm straight over the area where the muscles or joints feel tired or stiff. There is nothing to mix and nothing to warm up. The balm goes from the tube to the skin.
Step 4, press lightly. Use the flat of your fingers or your palm and press the balm onto the skin so that it settles and stays in place. Gentle pressure is all it takes, and it turns the application into a small moment of care.
Step 5, once or twice a day. Use the balm once or twice a day, depending on how strong the discomfort feels. A calm day might need only the evening session. A day of heavy lifting or long driving might call for the morning as well.
How much Penetrex Balm should I take?
A thin layer, in the amount you need to cover the area. The tube is soft and spreadable, so a small amount goes a long way, and your skin will tell you when you have used enough: the area is covered, the scent is pleasant and the balm has settled into a smooth, even film.
Amount by area:
- A knee: a thin layer over the front and sides, like a light coat of lotion.
- A shoulder or the side of the neck: a thin layer over the muscle, not a thick coating.
- A calf or thigh: a thin layer along the muscle, spread with long, light strokes.
The balm is made to be spread and pressed, not piled on. A thinner layer also makes the cool-then-warm feeling more pleasant, and it keeps the tube in your bag for longer.
How do I apply a balm to each area?
Knees
Sit on a chair with your foot flat on the floor, so the skin over the knee is relaxed. Spread a thin layer over the front and the sides of the knee, then press lightly with the flat of your hand. Think of the stairs at home, the walk to the stage, the long day at the stall: this is the area that appreciates a fresh minute at the end of it.
Lower back
Reaching your own lower back is awkward, so put a little balm on your fingertips and spread it over the skin you can reach, or ask a family member to spread it for you. Drivers and boda boda riders often do this in the evening, standing in front of a mirror or leaning on a wall. Wash your hands straight afterwards.
Shoulders and neck
Warm the balm between your fingertips, then spread a thin layer over the top of the shoulder and the side of the neck, staying well below the hairline and away from the face. Desk workers like this one at 9 pm, when the laptop is closed. Take a slow breath in: the eucalyptus scent is part of the pleasure.
Calves and thighs
After a day on your feet, a run or a game of football on the weekend, sit down, stretch the leg out and spread a thin layer over the muscle with long strokes from the ankle upwards. Press lightly, then pull your socks or trousers back on once the balm has settled on the skin.
More by area: knee comfort, back comfort, shoulder and neck comfort and muscle care after work or sport.
What is the best time of day to use Penetrex Balm?
Penetrex Balm is used once or twice a day, and most people tie it to a moment that already exists in the day. The usual choices:
- After the evening wash. Skin is clean, you are home and the scent gives the day a calm ending.
- Before bed. A thin layer, a few slow breaths of lavender and eucalyptus, then lights out.
- Before a long road day. A matatu driver or boda boda rider might use a thin layer on the lower back in the morning, then again at night.
- After sport or farm work. Once you have washed off the dust of the shamba or the track, the balm is a welcome finish.

What will I feel when I apply the balm?
Expect a short and pleasant sequence. First comes the smell: fresh blue gum, mint and a soft floral background. Within seconds the skin feels cool, which is the work of menthol. Then a gentle warmth builds, which comes from methyl salicylate. The cool and the warm overlap for a while, then fade away smoothly.
It is a sensory feeling, not a change in the temperature of your skin, and it is a lovely part of using it. If the feeling is stronger than you like, use a thinner layer next time. If you want to know why the two sensations arrive in that order, the menthol page and the methyl salicylate page explain it in plain words.

Tips for comfortable use: what to avoid
Habits that keep a balm with menthol and methyl salicylate comfortable to use:
- Keep the balm away from eyes, lips and the inside of the nose. It is made for the skin over muscles and joints, not for the face.
- Choose unbroken skin. Wait until a scratch, a cut or irritated skin is back to normal before using the balm on that spot.
- Keep the area uncovered. A tight bandage or a heat pad on top of a balm is not a comfortable combination. Loose clothing is perfect.
- Pick a cooler moment after a hot shower. Let the skin return to normal temperature before applying, so the warm feeling stays gentle.
- Test first if your skin is sensitive. A small patch on the forearm tells you what to expect. Details are on the safety page.
Wash your hands, then store the tube properly
Wash your hands with soap and water after every application. Menthol and plant oils linger on the fingertips, and the last thing you want is to rub your eyes with them. If you have used a fingertip to spread the balm over a hard-to-reach area, wash twice if you like.
The tube itself is easy to look after:
- Close the cap tightly after each use.
- Keep the tube away from direct sun and heat. A drawer, a bag or a shelf in the bedroom works well; a dashboard or sunny window sill does not.
- Keep it out of the reach of children, in the same place you keep your other personal care products.
- Do not swallow the balm. It is for external use only.
Common mistakes to avoid
A thin layer and a gentle press are the method. These are the slips to avoid:
- Using too much. A thin layer is the method. A thick layer just takes longer to settle and uses the tube faster.
- Rubbing hard. The method is to press gently, not to scrub.
- Forgetting to wash your hands. It takes ten seconds and avoids a sharp surprise near the eyes.
- Leaving the cap off. A closed cap keeps the scent and texture exactly as they should be.
- Applying straight after a very hot shower. Wait a few minutes first.
- Skipping the patch test when your skin is sensitive. It costs two minutes and gives peace of mind.

How long does a 50 g tube last?
It depends on how many areas you use it on and how often. A single knee once a day makes one tube last a good while. Shoulders, lower back and both legs twice a day will use it faster.
What you can control is the layer. Keep it thin, press it in lightly, close the cap and store the tube out of the sun, and a 50 g tube does its job for as long as you need it. When it starts to run low, you can place a new order from the order page in less than a minute.
Ordering takes a name and phone number, then a confirmation call between 11:00 and 23:00 Nairobi time, and payment on delivery. One 50 g tube costs KES 5,990; the price page has the details.

Questions about using Penetrex Balm
How do I use Penetrex Balm step by step?
Clean and dry the skin over the area, squeeze out the amount you need, spread the balm directly over the area, press it gently so it settles, and use it once or twice a day depending on how strong the discomfort feels. Wash your hands afterwards.
How much Penetrex Balm should I apply?
A thin layer is enough. Take the amount you need to cover the area, spread it and press lightly. A bigger layer does not make the scent or the cool-then-warm feeling any better, and a thin layer makes the tube last.
How often can I use Penetrex Balm?
Once or twice a day, depending on how strong the discomfort feels. Many people choose one moment in the evening and add a second in the morning on days when they need it.
Should I rub the balm in hard?
No. The method is to spread the balm over the area and press it gently so that it settles and stays in place. A light touch is more comfortable than hard rubbing.
Can I use Penetrex Balm before a hot shower?
It is more comfortable to apply the balm after your shower, once the skin is clean and dry. Applying it and then stepping straight under hot water makes the warm feeling stronger than most people enjoy.
Can I cover the area with a bandage or use a heat pad?
It is best not to. A balm with menthol and methyl salicylate feels best on open, dry-skinned areas, so avoid a tight bandage or a heat pad over it. Loose clothing is fine.
Do I need to wash my hands after applying it?
Yes, wash your hands with soap and water straight after. Menthol on the fingertips is not something you want near your eyes, lips or nose.
How should I store the tube?
Close the cap tightly after each use, keep the tube away from direct sun and heat, for example not on a dashboard or a sunny windowsill, and keep it out of the reach of children.
How long does a 50 g tube last?
It depends on how many areas you use it on and how often. One knee once a day stretches a tube much further than shoulders, back and legs twice a day. Because the method asks only for a thin layer, the tube lasts longer when you keep the layer light.
Where can I read about the ingredients and the precautions?
The ingredients page lists everything printed on the carton, and the safety page covers the simple precautions for balms with menthol and methyl salicylate.
