PanOxyl Acne Creamy Wash

A 4% benzoyl peroxide wash that kills acne bacteria without driving resistance. One of the few drugstore products dermatologists genuinely rely on.
At a Glance
Recommended

Benzoyl peroxide kills acne bacteria by releasing oxygen, and bacteria cannot become resistant to it. That is why it is often paired with antibiotics like clindamycin — it keeps the antibiotic working over time.

Strength is not everything. Studies show 4% is about as effective as 10%, with far less dryness and irritation. Higher concentrations mostly just burn more.

As a wash rather than a leave-on, contact time is short. That reduces irritation while still delivering benefit, and it makes benzoyl peroxide practical for larger areas like the chest and back.

How it works

Benzoyl peroxide is one of the few acne ingredients bacteria cannot become resistant to — it works by releasing oxygen, which acne bacteria simply can't survive. That's why dermatologists pair it with antibiotics like clindamycin or doxycycline: it keeps the antibiotic working over time.

The 4% version is the smart pick. Studies show 4% is about as effective as 10%, with considerably less dryness and irritation. Higher isn't better here — it just burns more.

As a wash rather than a leave-on, contact time is short, which further reduces irritation while still delivering the benefit. Good for the face, and genuinely excellent for chest and back acne.

Cheap, available everywhere, and it works.

Everyday habits

How to use it
  • When: Once or twice a day.How much: A dime-sized amount, lathered with water. Steps: Wet the skin, massage in for 20 to 30 seconds, then rinse well. Contact time: As a wash it rinses off quickly, which keeps irritation down while still working. Next: Follow with a moisturizer, especially at first. Go slow: Start every other day and build up if it feels drying. Careful: It bleaches fabric — use white towels and bedding. Do not use it at the same time as hydroquinone, which can temporarily stain skin.
Who should be careful+

It bleaches fabric. This is not a minor annoyance — it will ruin coloured towels, pillowcases, and shirts. Use white towels and white bedding, and rinse thoroughly.

It can be drying, especially at first. Start every other day and build up. Follow with moisturizer.

Don't use it at the same time as hydroquinone — the two react and can temporarily stain the skin.

Questions people ask+
Can I use it on body acne?Yes. It is genuinely good for chest and back acne, not just the face.
Will it bleach my towels?Yes. Benzoyl peroxide bleaches fabric, so use white towels, pillowcases, and clothing.
Is 4% strong enough?Yes. Research shows 4% works about as well as 10% with less dryness, so higher is not better here.
Can I use it with other acne products?Do not use it at the same time as hydroquinone, which can react and temporarily stain skin. Introduce other actives slowly.
Why is my skin dry after using it?Benzoyl peroxide can be drying, especially at first. Start every other day and always follow with moisturizer.
Does it cause resistance like antibiotics?No. Bacteria cannot become resistant to benzoyl peroxide, which is a key advantage.
