Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. The two main causes of acne are excess oil production and inflammation.
Excess oil production occur when the sebaceous glands produce too much sebum, an oily substance that lubricates the skin. Sebum is normally released on to the surface of the skin to keep it hydrated. However, when there is an excess of sebum, it can mix with dead skin cells and create a blockage in the hair follicle. This blockage can lead to inflammation and infection, which can cause pimples, blackheads, or whiteheads to form.
Inflammation occurs when the body’s immune system responds to a foreign invader, such as bacteria or a blocked pore. The immune system releases chemicals that cause redness, swelling, and pain in the affected area. In acne-prone people, inflammation can trigger breakouts even if there is no excess oil production or blockage present.
Acne has mainly three causes: overactive sebaceous (oil) glands, abnormal shedding of dead skin cells, and the fast production (proliferation ) of acne-causing bacteria
Acne is a very common skin condition that affects people of all ages. It is characterized by the appearance of pimples, blackheads, whiteheads, and other blemishes on the face, neck, chest, back, and shoulders. Acne occurs when the hair follicles become clogged with oil and dead skin cells. When these follicles are blocked, oil builds up under the skin and provides an ideal environment for bacteria to grow. The bacteria cause inflammation and swelling, which leads to the formation of pimples.
There are several factors that can contribute to the development of acne. One of the most important is hormones. During puberty, both boys and girls experience an increase in hormones called androgens. These hormones stimulate the sebaceous glands, which produce an oily substance called sebum. Sebum helps keep our skin lubricated and soft.
However, when there is too much sebum produced, it can combine with dead skin cells to form a plug that blocks the opening of the hair follicle. This plug prevents sebum from reaching the surface of the skin where it can be properly eliminated. The build-up of sebum and dead skin cells inside a blocked hair follicle provides an ideal environment for bacteria to grow.
The two main types of bacteria that are involved in acne are Propionibacterium acnes (P. acnes) and Staphylococcus epidermidis (S. epidermidis). P. acnes is a type of gram-positive bacterium that is normally present on our skin but only causes problems when there is an overgrowth due to blockage of pores or accumulation of dead skin cells or sebum. S. epidermidis is another type of gram-positive bacterium that is also normally present on our skin but can cause infections when there is an injury or break in the skin.
You might be surprised that these factors are not related to what you eat or your skincare routine
Acne is a very common skin condition that affects people of all ages. There are many different factors that can contribute to the development of acne, but the two main causes are hormonal changes and bacteria.
Hormonal changes are one of the most common causes of acne. When hormones fluctuate, they can cause an increase in oil production, which can lead to clogged pores and breakouts. Hormonal changes can be caused by puberty, menstrual cycles, pregnancy, stress, and certain medications.
Bacteria is another major cause of acne. When pores become clogged with oil and dead skin cells, they provide the perfect environment for bacteria to grow. This can lead to inflammation and pimples.
