How To Get Rid of Back Acne

Why do we get back acne?

Acne outbreaks occur when there is excessive sebum production or accumulation of dead skin cells, leading to blockage of hair follicles. This, in turn, creates an environment for the growth of bacteria called Propionibacterium acnes. The presence of these bacteria triggers an immune response, causing inflammation and the formation of pimples.

Various factors contribute to the development of acne. Genetic factors and certain medications, such as antidepressants, can be involved. Hormonal imbalances, sweat, and stress are also known to play a role. Back acne, specifically, can be caused by friction, tight clothing, or pressure from bags or backpack straps.

Research has suggested that diet may also impact acne formation. Specifically, carbohydrates that raise blood sugar levels, known as high glycemic index foods (e.g., white bread, sweets, and cereals), have been associated with acne. To address back acne, it is advisable to reduce consumption of high glycemic index foods and incorporate low glycemic index foods such as fruits, vegetables, nuts, whole grains, and minimally processed grains.

It's important to note that trying multiple acne treatments simultaneously can potentially lead to new acne outbreaks. It typically takes around four weeks for acne products to show their effectiveness, so patience is key. Avoid overstimulating your skin during the treatment process.

Types of back acne

Back acne and acne scars can be broadly classified into the following types.

  • Whiteheads: A type of mild acne. They are small bumps that have accumulated keratin and sebum.

  • Blackheads: A type of mild acne. Blackheads are caused by the oxidation of keratin and melanin in clogged pores that have opened up.

  • Papules: Tiny red bumps less than 1 cm in diameter.

  • Pustules: Red bumps. The difference between papules and pustules is that the latter are filled with pus or other fluid.

  • Nodular acne: painless, lumpy, hard pimple. It is red, black, large, and deep under the skin.

  • Cysts: One of the most severe acne

  • Keratosis pilaris: Sometimes called “chicken skin.” It is formed when dead skin cells get stuck in hair follicles. They appear mainly on the arms and upper thighs.

  • Hypertrophic scars: The most common type of back acne scar

  • Keloid scars: scar tissue that has become shiny and smoother

  • Atrophic scars: Scars that appear sunken or pitted.

At-home back acne treatments

Next, we will introduce over-the-counter drugs and cosmetics that you can use for acne treatment.

  • Alpha hydroxy acids (AHAs)

AHAs remove dead skin cells and prevent clogged pores. It also improves acne scars, skin discoloration, and roughness by exfoliating the top layer of the skin.

  • Lactic acid

Some studies suggest that lactic acid is effective for pigmentation and acne scars. Many cosmetics contain lactic acid, making it one of the easiest to find in any drugstores.

  • Salicylic acid

Salicylic acid is said to unclog pores and exfoliate. It can be highly irritating to the skin, so we recommend using it only on one part of the skin, not the entire body.

  • Benzoyl peroxide

Improves acne by killing bacteria in pores.
