Rosacea and Acne are Very Different

Written by on October 12, 2012 in Acne Treatments with 0 Comments

One confusion that seems to follow the condition rosacea is the temptation to call the condition acne rosacea.

This naming can be unhelpful as it might lead you to think that rosacea is just a form of acne.

Some recent research has confirmed that the bacteria P. acnes does not appear to play a major role in rosacea.

Rosacea is not Acne

We now know that there are important differences between acne and rosacea. Even the papules and pustules of rosacea are thought to be different to nodular acne.

Although there may be some overlap with treatments that work for acne and rosacea, in general acne treatments are not as effective or as well tolerated by rosacea sufferers.

The Bacteria Propionibacterium Acnes

The cause of acne is complicated and multi-factorial, much like rosacea in that regard.

P. acnes is thought to be a major culprit in acne development.

As far as P. acnes is concerned we do know that it cannot survive in the presence of oxygen, and this is why benzoyl peroxide is an effective treatment for acne. Indeed benzoyl peroxide is useful because p. acnes cannot become resistant to its use. Rosacea sufferers know that BP is likely to be too harsh as a treatment.

Rosacea and Propionibacterium Acnes

This abstract describes some research where 82 rosacea sufferer were examined for P. acnes. Only 8.5% were found to have this bacteria present.

This lead the researchers to confirm that P. acnes does not play a major role in rosacea.

No link between rosacea and Propionibacterium acnes,

Rosacea is a common skin disease in adults affecting mainly the facial skin.

Although inflammation appears to play a pathogenic role in rosacea, initiating factors are largely unknown.

Microbial involvement in the development of rosacea has been suggested previously.

We aimed to visualize Propionibacterium acnes in the skin compartments of rosacea patients.

Facial skin biopsies from 82 rosacea patients and 25 controls were stained with a P. acnes-specific monoclonal antibody (QUBPa3).

Seven of 82 patients (8.5%) tested positive for P. acnes which was present either as a biofilm (57% of positive) or a microcolony (43%) in colonized patients.

Our results suggest that P. acnes does not play a major role in the pathogenesis of rosacea.
