There are several factors that lead to the development of acne. These include inflammation, too much production of a skin oil called sebum, presence of bacteria, and the clogging of skin pores (follicles) with debris.3

This type of zit is most likely the result of underexfoliating: When you’re not sloughing off dead skin cells effectively, they can pile up on the skin’s surface and block your pores, which leads to a buildup of oil and — ta-da! — those whiteheads.
Most of the time, the glands make the right amount of sebum and the pores are fine. But sometimes a pore gets clogged up with too much sebum, dead skin cells, and germs called bacteria. This can cause acne.
1. Use a spot treatment after the potential scar appears. If you’re prone to scarring or have a particular bad one-off pimple, apply a targeted healer like Clean and Clear Mark Treatment to the area. It uses salicylic acid to prevent further breakouts or damage to the skin. “However, sometimes salicylic acid can temporarily worsen inflamed acne,” Lortscher warns. So, use it sparingly, and discontinue if you experience any additional inflammation.

An unintended effect of limiting access to isotretinoin was an increase in health disparities due to the limited access to publicly funded and private Dermatologists in New Zealand.25 The result was that a person living in the least deprived socioeconomic area was 2.5 times more likely to be prescribed isotretinoin than a person living in the most deprived area, and that Māori and Pacific peoples were five times less likely to be prescribed isotretinoin than people in other ethnic groups, largely New Zealand Europeans.25 This is despite the fact that there is no significant evidence of an association between the incidence of acne and deprivation level or ethnicity.25, 26 One of the primary reasons for widening access to isotretinoin was to reduce this disparity.
Antibiotic resistance in C acnes (formerly P acnes) is common and is a significant threat to acne treatment.  Antimicrobials should be combined with a topical retinoids for greater clearing of lesions and to increase the potential for shortened antibiotic treatment. They should be used with benzoyl peroxide to reduce the likelihood of resistance.  Concurrent use of oral and topical antibiotics should be avoided and should not be used as monotherapy. If acne relapses, use the same antibiotic if it was previously effective. It may also be helpful to use benzoyl peroxide for 5-7 days between antibiotic courses to reduce resistance in organisms on the skin.
