Congested skin is caused by a build-up of dead skin cells that have been compacted within the follicles of our skin. If left untreated, these cells can mix with sebum and develop into congested follicles, blackheads, and white heads and even pustules. We can end up with a rough dull and thickened skin texture if we do not regularly cleanse and exfoliate the area. The are many non-invasive treatments that provide effective results.
A blackhead occurs when on open follicle becomes compacted with dead keratinized skin cells. This follicle is open which oxidization happens leading to blackening of the tip.
Whiteheads develop when the keratinized dead skin cells and sebum blocks a follicle. These are closed so no oxidization happens instead they may have a white tip. These can develop further into pustules.
