Why oily skin causes breakouts

Oily skin has active sebaceous glands that produce skin oil for one purpose: to protect and soften the surface. The problem starts when sebum is produced in excess.
It mixes with dust, make-up residue and dead skin cells, and the pores become blocked from the inside out. This is how the most common breakouts on oily skin appear: blackheads, whiteheads and deeper inflamed spots, particularly around the nose, chin and forehead.
The longer the blockage remains, the more visible the inflammation becomes, which is why regular, correct cleansing is essential from the very first signs.
Sebum, enlarged pores and the T-zone
The T-zone covers the forehead, nose and chin, where the face has the highest concentration of sebaceous glands. When sebum is produced in larger amounts, the pores there respond by physically widening to let through a greater volume of oil.
This is how visibly enlarged pores develop, which makes it even easier for grime to build up. The skin across the T-zone often looks shiny within hours of washing, while the cheeks and eye area stay drier, which is typical of combination skin. Recognising this pattern is the first step towards targeted care for oily skin, rather than treating the whole face the same way.
What causes excess sebum
Excess sebum production is rarely down to a single cause. Hormonal changes, heat and humidity, stress and even harsh cosmetics can all put a strain on the skin at once. Here are the most common triggers behind more sebum and more breakouts.
Oily, combination or dry: identify your skin type
Before choosing a routine, it's worth pinpointing exactly which skin type you're dealing with. The signs differ noticeably, and getting it wrong often leads to the wrong products and even more breakouts.
| Skin type | Signs |
|---|---|
| Oily | Visible shine across the whole face, enlarged pores, frequent blackheads and breakouts, especially in the T-zone. |
| Combination | Oily T-zone (forehead, nose, chin), but normal to dry cheeks and eye area. |
| Dry | A tight, flaky feeling, a matte and sometimes rough texture, minimal shine. |
Caring for oily skin without over-drying

The most common mistake with oily skin is over-cleansing. When you strip away all the sebum with a harsh product, the skin reads this as a warning sign and produces even more oil to protect itself.
The result is a vicious circle: you wash, the skin turns shiny again within hours, you wash again. Dehydrated skin underneath an oily surface actually makes the problem worse, so the goal isn't "dry" skin, it's balanced skin. Choose formulas that cleanse deeply without breaking down the lipid barrier, and add a light, non-heavy moisturiser even if your skin is oily.
- Cleanse your face morning and evening with a gentle, non-ionic product
- Use herbal waters to mattify without drying the skin out
- Moisturise with a light, non-greasy texture
- Change your pillowcase regularly
- Excessive or repeated washing during the day
- Alcohol-based, harshly drying toners
- Rubbing or squeezing spots
- Heavy, comedogenic creams
For cleansing itself, choose a gentle formula designed for everyday use. The Natural Cleansing Foam for the Face with Lemon Balm and Geranium removes excess sebum and grime without over-drying, while the prebiotic in its formula supports the skin's natural barrier. The soft mousse texture works without rubbing, which matters for skin prone to inflammation.
