I knew it. Benzoyl Peroxide damages skin. After using it for years and years and years, I've noticed that my skin is horribly aged and damaged from it. I was just looking up some information on Hydrogen Peroxide and came across information that states that it causes mild tissue damage in open wounds. Then I thought, well, wait...Benzoyl Peroxide is very similar to Hydrogen Peroxide, so I wonder if Benzoyl Peroxide also causes this tissue damage. After all, when a whitehead bursts, it's an open wound, active acne lesions are often open wounds. This is just some of the information that I came across. I'm living proof that it's true...
"Benzoyl Peroxide and Premature Skin Aging: Benzoyl peroxide creates free radicals and is known to cause premature skin aging, just like repeated sun exposure or persistent acne. Damage is determined by the concentration of benzoyl peroxide and the frequency and duration of use. While moderate to severe acne will cause the skin to age quickly, the use of benzoyl peroxide will significantly increase this speed."
"Benzoyl peroxide used to fight acne bacteria inflicts a similar damage to your skin. People who have treated chronic acne with benzoyl peroxide frequently learn too late that they have severely aged their skin well beyond its chronological age and may have increased their potential of skin cancer."
"Benzoyl Peroxide Cautions: Benzoyl peroxide (BP) generates free radicals in the skin. Its effect is similar to unprotected sun exposure. The redness of the skin (erythema), caused by sun exposure and BP, are both the result of free radicals (oxidative stress) upon the skin. Repeated sun exposure or BP use generates free radicals that damage the skin's structure and cellular DNA, resulting in premature aging of the skin. The extent of the damage and aging from BP is determined by the concentration of BP, the frequency of application and the duration of its use.
Because BP generates free radicals it interferes with and slows the healing process. The red and brown marks that are a part of the acne healing process may last weeks longer when BP is a regular part of the daily regimen.
BP has been linked to cancer for a number of years and many research journal entries state "benzoyl peroxide is a free radical-generating skin tumor promoting agent." Performing a word search of the words "benzoyl peroxide cancer" in PubMed in the National Library of Medicine produces 102 articles from medical publications dealing with research aspects of BP and cancer. About two-thirds of the research supports linkage between BP and skin cancer."
"Benzoyl Peroxide (BP) products have been on the market for years. Truth is, BP does work to some degree, however, it will only work (consistently) for mild acne. BP can cause dryness and irritation to the skin even in lower strengths. Skin can also build a resistance to the actions of BP forcing acne sufferers to use products with higher percentages on a frequent basis.
BP was linked to increased risks of skin cancer by the U.S. Food & Drug Administration in 1992. Medical periodicals contain many scientific articles concerning BPâ€™s possible dangers. We believe that if the FDA ever follows up its 1992 health warnings with an outright ban, the billion dollar plus share of the acne market, now held by BP products, will be up for grabs.
The FDA is preparing new labeling information for acne products containing BP, including Clearasil and Oxy-5, Dr. Murray Lumpkin told The Gazette. Lumpkin is chief of the anti-infective-drug division at the agency. The FDA plan comes seven years after a senior toxicologist at Health and Welfare Canada failed in his efforts to have prescription and non-prescription acne products with BP banned. Studies show that BP can help tumors develop in rodents, Lumpkin said."
"Excessive sun exposure and exposure to the environment causes anatomical degradation of skin which accumulates over time. Every time the skin is photo-damaged or oxidized with therapeutic products such as benzoyl peroxide, the damage produces permanent effects on skin. Although the skin has an ability to repair such damage at an early age, with aging and the depression of the immune system, the ability of the skin to spontaneously repair itself is lost. Alterations in the skin resulting from such damage are apparent microscopically at an early age. As time goes by, the consequences of such degradation accumulate, with the effects being most pronounced at areas of excessive exposure, such as the skin around the eyes. The effects of the damage become visible to the unaided eye as more cells begin to degenerate."
There's plenty more evidence out there.
Needless to say, I won't be going near the stuff anymore. At all. It's already caused me too much damage.
