The geometric mean counts of P. acnes per follicle in the skin of acne patients is around 115,000, while in normal skin is practically zero. Patients with acne are less linoleic acid, the fat in their age-matched controls. This deficiency can cause abnormal desquamation of epithelial cells follicle that leads to the formation of microcomedones and comedones.

We can use topical retinoids such as adapalene (Differin ®), tretinoin (Retin-A ®, Retin-A Micro ™ or Avita ®), or tazarotene (Tazorac ®), to correct abnormal keratinization, anti-androgen agents and isotretinoin to decrease sebum production, and antimicrobial agents and antibiotics to clear up acne.

For optimal results, topical retinoids should be used for several months … Combined treatment with antibiotics, either topical or systemic, it makes sense for most patients. Two of the combinations popular mild to moderate inflammatory acne are (1) adapalene, tretinoin or tazarotene with benzoyl peroxide, and (2) topical retinoids with a peroxide benzoyl / erythromycin combination.

Pyoderma facial and acne fulminans are quite rare. Acne conglobata, however, is much more frequent. A Again, there is intense inflammation. Numerous deep, inflammatory nodules appear, some of which are to form fistulas in the face and trunk. Scarring can be a problem, too. Isotretinoin is generally effective, although some patients may require systemic corticosteroid use, or concurrent or prior to isotretinoin.

If a woman has evidence of hormonal abnormalities such as hirsutism or abnormal menstrual periods, should have a complete hormonal work up, and results can help guide the choice of hormone treatment. Treatment with corticosteroids may be useful for those who have overproduction of adrenal androgens. For those with excessive ovarian androgen production, oral contraceptives containing estrogen or progestin are the best bet.

Because retinoids tretinoin (Retin-A) can be irritating to some patients should be started at a low concentration of the cream, which is available at 0.025%, 0.05% and 0.1% concentrations, or gel, which comes in 0.01% and 0.025% concentrations. If the patient tolerates the medication, the dose may be increased in increments.

Generally, acne begins at the pre-pubertal period – anywhere from 8 to 13 – but it is not uncommon for girls 7 years. The adrenal glands have matured and start to release greater amounts of adrenal androgens. The secretion of sebum by the sebaceous glands is triggered by androgens. During this initial period, the child may develop noninflammatory comedones on the "T-Zone" – the forehead, chin, nose, and nasal areas par. These precursor lesions are only a result of increased sebum production and abnormal desquamation in the follicle. As the child becomes pubescent and mature gonads, increases the production of androgens, like the secretion of sebum. The follicular environment, so it is conducive for the proliferation of P. acnes colonies, which can initiate the development of inflammatory lesions.
