Acne and Oily Skin: Understanding Sebum Buildup and How to Treat It

Struggling with oily skin and acne breakouts? Learn how sebum buildup causes acne and discover the best skincare routine for oily, acne-prone skin using Acne.org.za’s dermatologist-developed products.

Why Does Oily Skin Lead to Acne?

If you have oily skin and frequent breakouts, you’re not alone. Oily skin is one of the leading causes of acne. To understand how to manage it effectively, it’s important to understand what’s happening beneath the surface.

Our skin naturally produces an oily substance called sebum, which is essential in moisturising and protecting skin. However, when the sebaceous glands produce too much sebum, it can mix with dead skin cells and clog pores.

This sebum buildup creates the perfect environment for bacteria (Cutibacterium acnes) to grow, leading to pimples, blackheads, whiteheads, and even painful cystic acne.

Key causes of oily skin and acne include:

  • Hormonal changes (especially during puberty, menstruation, pregnancy, or stress)
  • Genetics
  • Poor skincare routines
  • Using overly harsh products that strip the skin

When your skin feels attacked or overly dry, it often reacts by producing even more oil, worsening the cycle. That’s why the best way to care for oily, acne-prone skin is to balance, not strip.

How to Treat Acne and Oily Skin Effectively

The goal for treating oily skin and acne is to control sebum production, clear clogged pores, and maintain a healthy skin barrier.
