2.5% Benzoyl Peroxide products are manufactured in a such concentration that it can't harm your skin. It is commonly accepted that Benzoyl Peroxide to be produced under the following concentrations: 2.5%, 4%, 5% and 10%. Even if 10% for many it might appear to be an irritating dose and too much, it is still considered to be safe.

Benzoyl Peroxide is considered to be a carcinogenic product if it is applied on unprotected skin in 100% concentration. In pure form, Benzoyl Peroxide becomes extremely aggressive and harmful to the skin, it may lead to serious damages and induce skin cancer, tumors. Fortunately, you can’t find Benzoyl Peroxide in shops in such a concentration, so you’ll never take the wrong bottle of 100% instead of 2.5%.

Where can 2.5% doses of benzoyl peroxide be found?

In Europe, New Zealand, and Australia - Benzoyl Peroxide is used in a 4% concentration. North American dermatologists (Canada, USA) usually recommend the usage of a lower dose - 2.5%. The latest dose is the safest one and it causes a smaller number of allergies or skin irritations. Since it is used on problematic skin and on inflammation areas, probably it is the most rational dose ever. It will not call some supplementary skin inflammation and irritation, which is a good thing in acne.

Dermatologists all over the world usually tend to recommend this dosage, because it is the best to start with. In case the person is allergic to benzoyl peroxide or can’t support this medication, than the side effects are minimal, compared to a 4% or 10% dose, where the side effects, if occur, will be doubled or quadrupled.

If your skin does accommodates easily to a 2.5$ dosage, than you can increase the frequency of ointment or gel usage up to 3-4 times a day without any risk that some irritations or burnings will occur. However, the frequency you use a benzoyl peroxide product must be coordinated with your dermatologist and to be according his or her instructions.

The only thing you can do the best after you buy a 2.5% benzoyl peroxide product is to not overuse it and stick to you instructions as given by your dermatologist. If you decided to start a benzoyl peroxide cure on your own, then at least start with a small dosage and a concentration of 2.5% and not higher. You will save you money also, because if a higher concentration will become irritating, you’ll have to throw it, while with a 2.5% the probability of having some itches after it is very low.

Benzoyl Peroxide with Erythromycin to Prevent Antibiotic- Resistant Bacteria in Acne

Get cleared with a benzoyl peroxide treatment that helped thousands to fight acne!

Erythromycin-resistant strains of Propionibacterium acnes, first described in the late 1970s, appear to be becoming a significant clinical problem. Researchers in Britain previously reported that 25% of patients at their large acne center have erythromycin-resistant P. acnes on their skin, and they recently showed that patients with predominantly resistant P. acnes fail to respond to oral erythromycin therapy. In an effort to ensure the continued efficacy of erythromycin in acne therapy, these researchers investigated whether benzoyl peroxide, a broad-spectrum antibacterial agent, adds to the antibacterial effect of erythromycin.

Benzoyl peroxide was tested alone and in combination with erythromycin against 40 erythromycin-sensitive and -resistant strains of Staphylococcus epidermis and proprionibacteria in vitro. In most of the bacterial strains, the combination of agents was no more effective in inhibiting the organisms than benzoyl peroxide alone.

Comment: P. acnes may have developed resistance to erythromycin, a bacteriostatic agent, as a result of the introduction of topical formulations in the late 1970s or from years of long-term systemic administration of the drug. The emergence of resistant strains poses a potentially significant problem in the management of patients with acne. This study shows that the combination of erythromycin and benzoyl peroxide is not synergistic against the majority of erythromycin-resistant propionibacteria. However, the combined use of topical benzoyl peroxide with either topical or systemic erythromycin should prevent selection for erythromycin-resistant skin bacteria and should also reduce the number of resistant strains already present on the skin. It appears rational, therefore, to avoid using unopposed erythromycin and to combine it with benzoyl peroxide.

Benzoyl peroxide makes an effective treatment for mild to moderate acne. Start with a lotion or gel in a 2.5% strength. Higher percentages are available but may irritate the skin. Start with a lower strength to allow your skin to become acclimated to the benzoyl peroxide treatments. Move up to a higher strength if results are not seen after several weeks.

Most common treatment methods call for a thin layer of benzoyl peroxide lotion to be applied over a thoroughly cleansed and dried skin. It can be used once or twice daily. Apply thoroughly over all areas affected by acne. Do not use just as a spot treatment. Benzoyl peroxide must be applied to all affected areas of the skin, as it works to stop pimples before they erupt.

Benzoyl peroxide may bleach hair, towels, and clothing. Take great care during and after application to avoid letting it come in contact with any of these materials. You may want to wear an old shirt if benzoyl peroxide is applied to the back or body. Let the lotion dry thoroughly after your nightly skin care treatments before getting into bed at night, to avoid bleaching your pillowcase.

If a person is using a cleansing liquid or bar, they should wash thoroughly but gently with the product once or twice daily as directed. A small amount should be applied, not just to the outbreaks themselves, but also to the areas where outbreaks occur. Avoid getting benzoyl peroxide in the eyes, mouth or nose. If contact is made with these sensitive areas, flush gently with water and contact a physician if inflammation or irritation continues.

Benzoyl peroxide comes in a cleansing liquid or bar, lotion, cream and gel for the use on the skin. Benzoyl peroxide is also a key ingredient in many over-the-counter acne topical medications. Be aware when using products that feature benzoyl peroxide, because it has a bleaching effect on hair and clothing. They may also affect your cloth-covered furniture.

While using benzoyl peroxide, you should always avoid anything that might irritate the skin such as abrasive soaps or cleansers, alcohol, cosmetics and prolonged exposure to sunlight. Benzoyl peroxide dries out the skin, so some redness and peeling should be expected. It could take up to 4 to 6 weeks to see a noticeable improvement in your symptoms. If none is noticed by the end of that time frame, then you should contact your doctor.

Benzoyl Peroxide in the top 5 treatments for mild acne

Benzoyl Peroxide is one of the top five recommended treatments for mild acne, including whiteheads and blackheads. Acne affects most teenagers to some extent, but acne does not discriminate against age, sex or race.

While not a life threatening condition, acne can be upsetting and disfiguring. When severe, acne can lead to permanent scarring.

Even less severe cases can lead to scarring. While acne is not curable, it is 100% treatable with Benzoyl Peroxide.



The properties of benzoyl peroxide make it extremely useful in the treatment of mild to moderate acne. The anti-inflammatory properties will reduce swelling in infected papules and pustules, allowing a relief from the soreness that often accompanies acne outbreaks. The oxidizing factor dries out the thickened sebum or fluid within the acne and helps to alleviate the plugged pores, so that acne may heal without trauma to the area caused by popping the acne. To be most effective, one should use a benzoyl peroxide exfoliator.

Benzoyl Peroxide – Side effects

Get cleared with a benzoyl peroxide treatment that helped thousands to fight acne!

Using benzoyl peroxide I never noticed some exaggerated side effects. Maybe, because my skin was already too much irritated so it would be difficult to differentiate now what was an side effect and what wasn't. But, as I found on some sites, there may be some side effects in benzoyl peroxide usage, so I decided to post them here.



Serious side effects are not likely to occur. Stop using benzoyl peroxide topical and seek emergency medical attention if you experience an allergic reaction (shortness of breath; closing of the throat; swelling of the lips, face, or tongue; or hives).
Some burning, stinging, tingling, itching, redness, dryness, peeling, or irritation may be experienced while using benzoyl peroxide topical. Contact your doctor if these side effects are excessive. Less frequent application of benzoyl peroxide topical may be necessary.
Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.



Some problems with using benzoyl peroxide include:

1. Dryness of the treated area. If the skin is visibly scaly, apply a light non-oily moisturizer.
   
2. Skin irritation is rarely severe. Occasionally excessive irritation may lead to discontinuing use. Consider applying benzoyl peroxide less frequently.
   
3. Contact dermatitis (red, dry, itchy skin) can be due to irritation or allergy. It can be treated with a topical steroid such as hydrocortisone cream. Contact a physician if the irritation is persistent.
   
4. Benzoyl peroxide can bleach clothing. Make sure the treated area is completely dry before it touches clothing or bedding.
   

If the following symptoms occur, contact a physician immediately:

• Burning
  
• Blistering
  
• Excessive itching
  
• Redness
  
• Rash
  
• Swelling

Clean and dry the area of skin where you will apply benzoyl peroxide topical. Apply the medication to the affected area. Shake lotions well before use.

An overview on Benzoyl Peroxide in Acne

Get cleared with a benzoyl peroxide treatment that helped thousands to fight acne!

With various forms of acne striking teens as well as adults, benzoyl peroxide is one of the most common treatments for acne. Many of the products on the market today contain benzoyl peroxide including popular lotions, soaps, gels and creams. Most of these acne treatments are sold over the counter under such manufacturer names as Neutrogena Acne, Benoxyl, Clear by Design, PanOxyl, Clean & Clear, Clearasil and Oxy.

Benzoyl peroxide works by killing the bacteria that frequently causes acne infection; known as P. acnes. While this bacteria is present in almost everyone, it begins to create a problem and leads to the presence of acne when the sebaceous glands become clogged with sebum. Redness, pain and swelling result from the infection. As the medication kills the bacteria, the excess sebum dries which may lead to some of the more frequent side effects noted for this acne treatment.

As a peeling agent, one of the most common side effects of benzoyl peroxide for acne treatment is the fact that it tends to irritate the skin. Depending on the user, this irritation can range from slight to more severe. Individuals who possess very sensitive skin are cautioned to use the medicine less often or user a weaker strength of the medication. In some cases in which the medication causes the skin to become overly reddened or even peel, it may be necessary to consult a physician. Benzoyl peroxide can also cause the following conditions:

• Blistering, crusting or swelling of the skin
• Severe burning or redness of the skin
• Skin rash
• Darkening or lightening of the skin
• Discoloration of hair as well as fabrics

Many manufacturers recommend continual use of benzoyl peroxide for optimal acne treatment results, leading to the question of whether there might be any long term effects related to the use of this product. Due to the fact that benzoyl peroxide generates free radicals, there has been concern expressed that long term use of this acne treatment could lead to the development of skin cancer later in life. At the current time, there are no studies to indicate this; however it remains a theoretical concern.

Women who are pregnant are cautioned to consult their physician prior to using any acne treatment that contains benzoyl peroxide due to the fact that the effects of benzoyl peroxide on a developing fetus remain unknown.

Benzoyl peroxide does tend to cause skin irritation, especially in sensitive skin, so individuals with such conditions as eczema or sunburned skin are also cautioned not to use it.

In a clinical study performed by the Department of Dermatology at the University of Michigan Medical School in Ann Arbor; a combination gel acne treatment containing benzoyl peroxide was tested in more than 1250 patients with moderate to moderately severe acne vulgaris. The combination gel contained a 5% benzoyl peroxide solution. The most common side effect noted was dry skin with some isolated incidences of localized skin irritation.

Did Benzoyl Peroxide treated my acne?

Ok, this is a quite difficult question. I found on a forum that benzoyl peroxide may be a solution in acne, so I tested it on myself last year. Since then I used more than 5 tubes of Brevoxyl 4%, which, not regularly.
It is important to apply it on a clean skin and to avoid the contact with eyes, clothes and hair (it has a bleaching effect)
Back to my acne… since I started to use twice a day Brevoxyl (Benzoyl peroxide 4%) I observed first just a huge irritation, my skin became even more red and the spots became bigger and I thought “this is the end to all my future friendships and relationships” (I was 19)
But, in a 2 – 3 weeks, my family started to say me that there is an improvement of my skin and that it started to look better. I couldn’t see these changes because I looked myself in the mirror more than 5 times a day and it is impossible to remember yourself as you was 3 weeks ago (after more than 100 looks in the bathroom mirror)
Brevoxyl at first itched and it was an unpleasant sensation, especially in the evening. And it produces and little specific smell in contact to your skin.
But, now, to answer my question in the post title – I think no, Benzoyl Peroxide didn’t treated my acne, BUT it improved my situation considerably.
And I regret I have no photos in that period (it is a little hard to put me under focus) but it was a visible difference with me between and after.
