Acne

Acne vulgaris is due to an excess of androgens which promotes an increase in keratinization and follicular scaling but also the secretion of sebum. This will cause the skin pore to become blocked and subsequently inflamed by the opportunistic action of the bacterial flora present on the skin, leading to characteristic acne lesions in the form of comedones, papules, pustules and residual hyperpigmentations.

There is no single cause for oily and acne-prone skin. Acne can be a genetic condition or caused by external factors. Common contributing factors to acne include Hormonal fluctuations, stress, medication, climatic conditions, drugs, cosmetic ingredients that irritate the skin and clog pores, and hereditary conditions.
