What Causes Acne?

Most acne breakouts are influenced by:
- Stress and lack of sleep
- Use of unsuitable skincare or makeup
- Certain medications (e.g., corticosteroids)
- Genetic predisposition — if your parents had acne, you might be more likely to experience it too.
How Acne Develops
Acne is a common skin concern that begins deep within the pores. Here’s what happens:
- Hidden early stages: Pores get blocked, but you can’t see it yet.
- Excess oil (Sebum): Too much oil clogs the pores.
- Dead skin buildup: Excess skin cells block pores and form comedones (blackheads and whiteheads).
- Bacteria and acne: Once the pores are clogged, bacteria grow in clogged pores, leading to inflammation and acne.
If acne persists or becomes severe, it’s always best to consult a pharmacist or dermatologist for proper care and treatment options.
Oily Skin and Acne-Causing Bacteria
When sebum can’t flow out due to a blocked pore, it becomes trapped beneath the surface — creating the ideal environment for acne bacteria (P. acnes) to thrive.
These bacteria prefer low-oxygen conditions inside clogged pores, where they trigger acne. This leads to visible symptoms such as:
- Red papules (bumps)
- Pustules (bumps with white tips)
- Deep cystic acne (painful lumps under the skin)
Types of Acne
Acne can appear in different forms, depending on how the skin reacts. The most common types include:
- Blackheads: Small dark spots that appear when pores are clogged with oil and dead skin.
- Whiteheads: Small bumps formed when the same mixture is trapped beneath the skin’s surface.
- Active acne: Visible red pimple spots that may leave marks after healing.
- Acne marks: Dark spots that remain after breakouts, often caused by post-inflammatory pigmentation.
With the right skincare routine and gentle daily care, these concerns can be visibly reduced for clearer and healthier-looking skin.

Tips for Managing Oily and Acne-Prone Skin
To help keep your skin balanced and clear, follow these dermatologist-recommended tips:
- Cleanse gently with a mild cleanser formulated for oily or acne-prone skin. Avoid over-washing, which can strip the skin and increase oil production.
- Apply Eucerin ProACNE Solution Triple Effect Serum every morning and night. Consistency is key.
- Use non-comedogenic sunscreen daily to protect against UV rays and prevent post-acne marks.
- Avoid squeezing pimples — it can worsen inflammation and lead to long-term scarring.
- Choose lightweight, non-comedogenic makeup that won’t clog pores.
