Acne

Acne

Acne, also known as acne vulgaris, is a long-term skin disease that occurs when hair follicles are clogged with dead skin cells and oil from the skin.  Some people have severe acne resulting in hundreds of pimples across the face, chest, and back, although many treatments can help.

The glands produce an oily liquid called sebum. Sebum carries dead skin cells through the follicles to the surface of the skin. A small hair grows through the follicle out of the skin.

Pimples grow when these follicles get blocked, and oil builds up under the skin.

They tend to appear on the face, back, chest, shoulders, and neck.

Skin cells, sebum, and hair can clump together into a plug. This plug gets infected with bacteria, and swelling results. A pimple starts to develop when the plug begins to break down.

Propionibacterium acnes (P. acnes) is the name of the bacteria that live on the skin and contributes to the infection of pimples.

Research suggests that the severity and frequency of acne depend on the strain of bacteria. Not all acne bacteria trigger pimples. One strain helps to keep the skin pimple-free.

Causes

A range of factors triggers acne, but the main cause is thought to be a rise in androgen levels.

Androgen is a type of hormone, the levels of which rise when adolescence begins. In women, it gets converted into estrogen.

Rising androgen levels cause the oil glands under the skin to grow. The enlarged gland produces more sebum. Excessive sebum can break down cellular walls in the pores, causing bacteria to grow.

Some studies suggest that genetic factors may increase the risk.

Other causes include:

  • some medications that contain androgen and lithium
  • greasy cosmetics
  • hormonal changes
  • emotional stress
  • menstruation

Types:

Acne pimples vary in size, color, and level of pain.

The following types are possible:

  • Whiteheads: These remain under the skin and are small
  • Blackheads: Clearly visible, they are black and appear on the surface of the skin
  • Papules: Small, usually pink bumps, these are visible on the surface of the skin
  • Pustules: Clearly visible on the surface of the skin. They are red at their base and have pus at the top
  • Nobules: Clearly visible on the surface of the skin. They are large, solid, painful pimples that are embedded deep in the skin
  • Cysts: Clearly visible on the surface of the skin. They are painful and filled with pus. Cysts can cause scars.

Over-the-counter treatment:

Treatment depends on how severe and persistent the acne is.

Mild acne:

Mild acne can be treated with over-the-counter (OTC) medications, such as gels, soaps, pads, creams, and lotions, that are applied to the skin.

Creams and lotions are best for sensitive skin. Alcohol-based gels dry the skin and are better for oily skin.

OTC acne remedies may contain the following active ingredients:

  • Resorcinol: helps break down blackheads and whiteheads
  • Benzoyl peroxide: kills bacteria, accelerates the replacement of skin, and slows the production of sebum
  • Salicylic acid: assists the breakdown of blackheads and whiteheads and helps reduce inflammation and swelling
  • Sulfur: exactly how this works is unknown
  • Retin-A: helps unblock pores through cell turnover
  • Azelaic acid: strengthens cells that line the follicles, stops sebum eruptions, and reduces bacterial growth. There is cream for acne, but other forms are used for rosacea.

It is advisable to start with the lowest strengths, as some preparations can cause skin irritation, redness, or burning on first use.

These side effects normally subside after continued use. If not, see a doctor.

15 tips for managing acne:

Here are some tips for looking after skin that has acne or is prone to it.

  1. Wash your face no more than twice each day with warm water and mild soap made especially for acne.
  2. Do not scrub the skin or burst the pimples, as this may push the infection further down, causing more blocking, swelling, and redness.
  3. Avoid popping pimples, as this makes scarring likelier.
  4. A specialist can treat a pimple that requires rapid removal for cosmetic reasons.
  5. Refrain from touching the face.
  6. Hold the telephone away from the face when talking, as it is likely to contain sebum and skin residue.
  7. Wash hands frequently, especially before applying lotions, creams, or makeup.
  8. Clean spectacles regularly as they collect sebum and skin residue.
  9. If acne is on the back, shoulders, or chest, try wearing loose clothing to let the skin breathe. Avoid tight garments, such as headbands, caps, and scarves, or wash them regularly if used.
  10. Choose makeup for sensitive skin and avoid oil-based products. Remove makeup before sleeping.
  11. Keep hair clean, as it collects sebum and skin residue. Avoid greasy hair products, such as those containing cocoa butter.
  12. Avoid excessive sun exposure, as it can cause the skin to produce more sebum. Several acne medications increase the risk of sunburn.
  13. Use an electric shaver or sharp safety razors when shaving. Soften the skin and beard with warm soapy water before applying shaving cream.
  14. Avoid anxiety and stress, as it can increase production of cortisol and adrenaline, which exacerbate acne.
  15. Try to keep cool and dry in hot and humid climates, to prevent sweating.

Acne is a common problem. It can cause severe embarrassment, but treatment is available, and it is effective in many cases.
