Acne is one of the most common skin problems. It usually appears in adolescence but can continue or begin in adults. Understanding its causes, following gentle care and avoiding common mistakes makes a big difference. Here is a practical guide.
Why does acne appear?
It results from pores clogged with oil and dead skin cells, with a role for bacteria, inflammation and hormonal changes. Some factors increase it, such as certain oily skin products, friction, or repeated pressure on the skin.
Types of acne
- Blackheads and whiteheads (non-inflamed blockage).
- Red pimples and inflamed pustules.
- Deeper, more severe nodules and cysts that may leave scars.
A basic care routine
- A gentle facial cleanser twice a day without harsh scrubbing.
- A light, non-comedogenic moisturizer.
- A sunscreen suitable for oily skin during the day.
- Consistency and patience; results take weeks.
Common mistakes to avoid
- Squeezing pimples, which increases inflammation and scarring.
- Over-exfoliating or using a harsh cleanser that irritates the skin.
- Switching products quickly without giving treatment enough time.
- Skipping sunscreen for fear of more acne.
When to see a dermatologist?
If acne is moderate to severe, leaves scars, does not improve after weeks of regular care, or affects your wellbeing, seeing a dermatologist helps set a considered treatment plan based on your skin type and the severity of the condition.

Frequently asked questions
Does food cause acne?
The link varies between individuals, and some notice an association with certain dietary patterns. The foundation remains appropriate skincare, and any dietary observations can be discussed with the doctor.
Should I squeeze a pimple to clear it faster?
Squeezing is discouraged because it increases inflammation, scarring and infection risk. It is better to leave the pimple and treat it topically with suitable guidance.
When do results appear?
Acne treatments usually take several weeks to show results, and consistency matters more than quickly switching products.
Does sunscreen worsen acne?
Choosing a light, non-comedogenic sunscreen does not usually worsen acne; it protects the skin and reduces dark marks after inflammation.
