Acne: Cause And Symptoms

Acne is a skin issue that affects the hair follicles and sebaceous glands. These glands produce an oily substance called sebum. It helps keep the skin moisturized.

Sebum usually empties onto the skin surface through the pore. However, when there is too much sebum, It can clog hair follicles and promote the growth of acne-causing bacteria.

Acne affects all ages and races but is most common in teens and young adults. It mainly occurs on the face but can also appear on the back, chest, and shoulders.

Acne Types

Here are some common types of acne.

  • Acne vulgaris – includes blackheads, whiteheads, and pimples

  • Pustules – red papules containing pus
  • Nodules – large, painful bumps form under the skin
  • Cysts – large, painful bumps filled with pus


Acne has multiple factors contributing to its development.

  • Excess sebum production
  • The buildup of dead skin cells in the pore
  • Growth of bacteria in the pore
  • Hormonal changes, especially during puberty, pregnancy
  • Hormonal imbalance due to polycystic ovary syndrome
  • Family history
  • Certain medications, especially those containing hormones, corticosteroids, and lithium

Does Collagen Help With Acne?

There’s no conclusive evidence that collagen can help prevent or manage acne. However, collagen may stimulate new skin cell growth that reduces acne scars. Besides, it can improve acne-prone skin by strengthening skin barrier function, reducing inflammation, and boosting hydration.

Collagen is a crucial protein in the body’s tissues, providing structure, elasticity, and strength. However, its production decreases with age, resulting in wrinkles and sagging skin.

Why Is Collagen Good For Acne?

While it’s unclear how collagen directly impacts acne, it can still be a beneficial addition to the skincare routine of those with acne-prone skin. Let’s see how.

Skin Healing and Repair

When acne lesions occur, they can damage the skin’s integrity. Collagen may aid recovery after acne breakout and reduce the risk of hyperpigmentation by promoting wound healing and tissue repair.

Hydration and Sebum Regulation

Keeping your skin well-hydrated can help prevent excessive sebum production, a common cause of acne. Collagen helps keep your skin hydrated by retaining moisture and creating an environment less friendly to acne-bacteria development.

Inflammation Management

Inflammation is a hallmark of acne, leading to redness, swelling, and discomfort. Collagen supplements with anti-inflammatory properties can help alleviate redness, swelling, and discomfort associated with acne by reducing inflammation.

Support for Gut Health

Research shows that gut issues often lead to various skin conditions, including acne. Studies suggest that collagen peptides may improve gut health. Besides, collagen contains large amounts of the amino acids glycine, glutamine, and proline, which can benefit the intestinal tract and the stomach. Thus, improving gut health may help improve some skin conditions.

It can help even out the skin’s tone and texture by smoothing out the irregularities that arise from acne.

However, collagen supplements do not replace professional treatments like microneedling or resurfacing procedures.
