Top Acne Treatments: Medications, Creams & OTC Products

Acne, also known as acne vulgaris, is a common skin disorder characterized by red pimples or zits affecting the face, back, chest and shoulders. Teenage boys are more commonly affected than girls but it can occur at any age in both genders.

It is a non contagious inflammatory disorder involving hormones, inflammation and oil glands at the base of hair follicles. It is characterized by eruptions of varying intensity that may or may not cause scarring.



Types of Acne

Types of Acne

The types of acne based upon its clinical signs are:

  • Blackheads– They are blackish spots seen on the surface of the skin. They occur when skin debris and oil combine and block the follicle. It is visible open.
  • Whiteheads- Also known as comedones they are usually invisible and closed
  • Papules: Also known as pimples they are small pinkish swellings or bumps that appear on the skin
  • Pustules: They are small pus-filled bumps found on skin with a pink base and pus-filled top. They may later develop into Nodules and Cysts.
  • Nodules: They are painful large bumps found in the deeper layers of the skin
  • Cysts: They are large, painful, fluid-filled eruptions, which usually leave a scar.

Causes

Acne breakout because of the blocked pores. There are numerous tiny pores on the face associated with hair follicles. The sebaceous glands open into the hair follicles. The sebum produced by sebaceous glands and the dead skin cells (keratin) clog inside the follicles and is not brought to the surface of the skin. The clogging of pores results in acne. The bacteria Propionibacterium acnes multiply inside these pores, and it results in inflammation that leads to rupture of follicles.

Factors that Worsen Acne

  • Teenagers are prone for acne. During puberty, there is a surge of androgens. The androgens stimulate the oil producing glands or sebaceous glands to produce more sebum resulting in an increased outbreak of acne.
  • Hormonal problems- When the male hormone levels are high in females it causes acne. It can also occur in association with the menstrual cycle in females. Polycystic Ovarian Syndrome is a syndrome in women associated with hirsutism, hormonal imbalances, and acne.
  • Psychologically stressful states
  • Genetic factors
  • Environmental conditions such as high humidity
  • Cosmetics that are oily in nature, medications such as steroids, antiepileptics, lithium)
  • Pressure from helmets, tight collars, headbands, etc

Diet and Acne

Studies conducted in the past have confirmed the association of acne and diet. Recently it has been found that food with high glycemic index can aggravate and even trigger acne. Such food intake increases the blood sugar rapidly which causes the release of insulin in large levels. Insulin in turn stimulates the oil producing glands of the face resulting in increased sebum production and clogging.  Milk and dairy products also aggravate acne. Processed milk and milk products are much more harmful.  Studies have confirmed fewer outbreaks of acne among communities and regions consuming food with low glycemic index.



Treatment Depends Upon Severity of Acne

Acne occurs in different severities. The grades of acne according to the severity are:

  • Grade1 (Mild): There are only a few blackheads and whiteheads
  • Grade2 (Moderate): Blackheads, Whiteheads, multiple pustules and nodules limited to the facial area.
  • Grade 3 (Moderately Severe): Numerous papules and occasional nodules on the face and back.
  • Grade 4 (Severe): Painful multiple outbreaks of papules, pustules and nodules on the face, back, and chest.

Salicylic Acid:

Salicylic acid is an antiseptic that has excellent anti-inflammatory property. It helps in removing whiteheads and blackheads and also decreases the oil release from the sebaceous glands. Salicylic acid accelerates the turnover of cells and increases the growth of new cells. It thus prevents the clogging of pores and reduces the swelling.

Sulfur:

Sulfur has been in use in skin treatments of various diseases for many years. It oxidizes to sulfurous acid which acts as a reducing and antibacterial agent.

Retinoids:
