Acne results from a change in the way in which is laid down in the hair follicle, with the keratin becoming denser, and blocking the secretion of sebum. This hyper-keratinisation produces a sterile inflammatory response and a resultant plugging of the follicle causing a whitehead(close comedone)
Acne is also caused by the body’s increased production of the hormone androgen (produced by both men and women) which stimulates the sebaceous glands to produce more oil. The increased production of oil causes the pores to become blocked so that the oil cannot come up to the skin’s surface.
Factors that can aggravete acne:
- A humid environment with oil, chemicals or dirt
- Stress; emotional or physical
- Scratching or squeezing the infected area
- A woman going through a monthly period
- Certain types of medication
- Hormonal conditions/imbalances
