Also known as Crystacide, Hydrogen peroxide cream/solution.

Deze informatie is uitsluitend bedoeld als algemene richtlijn en vormt geen medisch advies. Raadpleeg altijd een gekwalificeerde zorgprofessional voor persoonlijke medische vragen. Bel in geval van nood uw lokale alarmnummer.

What it is used for

  • Cleaning minor cuts, grazes and wounds
  • Minor skin infections (low-strength cream)
  • Antiseptic skin cleansing

How it works

Hydrogen peroxide releases oxygen on contact with skin and tissue, which helps clean wounds and reduces certain bacteria on the surface.

How it is taken

Available as a low-strength antiseptic solution or cream for the skin. Apply to the affected area as the label directs, usually to clean, intact or minor broken skin. Use only skin-strength products as directed; higher-strength solutions are for other purposes and can damage skin if misused.

No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.

Common side effects

  • Temporary stinging, whitening or bubbling of the skin
  • Mild redness or irritation

Serious effects — get help

  • Severe burning, blistering or pain
  • Signs of an allergic reaction such as swelling, widespread rash or difficulty breathing

If a reaction is severe — for example trouble breathing, swelling of the face or throat, or collapse — go to the nearest emergency room now or call your local emergency number. Do not wait for an online consultation.

Interactions to watch

  • Do not combine on the skin with other strong antiseptics unless advised

Who should take care

  • Avoid the eyes; rinse thoroughly with water if it gets in
  • Do not use strong household or hair products as skin antiseptics
  • Avoid using repeatedly on deep or large wounds, which need clinical assessment
  • Keep out of reach of children

Frequently asked questions

Should I pour it on every wound?
Routine use on all wounds is not recommended, as it can irritate healing tissue. Clean water or saline is often enough; ask a pharmacist for minor wound care advice.
Why does it bubble on my skin?
The fizzing is oxygen being released as it reacts with the skin and wound surface, which is expected with antiseptic products.
Can I use the strong bottle from the cupboard?
No. Only low-strength products meant for skin should be used. Stronger solutions can burn the skin.
Is it good for acne?
It is not a recommended acne treatment. Speak to a pharmacist or clinician about proven acne options instead.
Is Hydrogen peroxide safe to take?
For most people it is safe when taken exactly as a doctor or pharmacist advises and as printed on the label. Tell your clinician about your other medicines and health conditions, and seek urgent care for any serious reaction.
