Acne: Causes, Treatment & Prevention – Expert Guide by a Dermatologist

Acne is one of the most common skin conditions affecting teenagers and adults. While many people think acne is only a teenage concern, adult acne is increasingly common in people in their 20s, 30s, and even 40s.

Persistent pimples, blackheads, and painful cystic acne can affect confidence and may lead to permanent acne scars if not treated early. Fortunately, modern dermatology treatments can effectively control acne and prevent long-term skin damage.

If you are looking for acne treatment in Mohali, consulting a qualified dermatologist can help diagnose the cause and provide personalized treatment for clearer skin.

What is Acne?

Acne is a chronic inflammatory skin condition that develops when hair follicles become clogged with oil (sebum), dead skin cells, and bacteria.

This blockage leads to different types of breakouts such as:

  • Blackheads

  • Whiteheads

  • Pimples

  • Pustules

  • Nodules or cystic acne

Acne most commonly appears on areas with high oil gland activity, including:

  • Face

  • Forehead

  • Chest

  • Upper back

  • Shoulders

Without proper treatment, acne can result in pigmentation and permanent acne scars.

Common Causes of Acne

Acne develops due to multiple internal and external factors.

Excess Oil Production

Sebaceous glands produce oil to protect the skin, but excess oil can clog pores, leading to acne formation.

Hormonal Changes

Hormonal fluctuations significantly influence acne. These occur during:

  • Puberty

  • Menstrual cycles

  • Pregnancy

  • PCOS

  • Stress

Hormones stimulate oil glands, increasing the risk of breakouts.

Bacterial Growth

A bacterium called Cutibacterium acnes grows inside blocked pores, triggering inflammation and redness.

Genetics

If parents had severe acne, there is a higher likelihood of developing acne as well.

Lifestyle & Diet Factors

Certain habits can worsen acne, including:

  • High sugar or high glycemic diet

  • Oily cosmetic products

  • Poor skincare routines

  • Stress and lack of sleep

Best Acne Treatments by Dermatologists

Treatment depends on the type and severity of acne. A dermatologist creates a customized plan to control breakouts and prevent scarring.

Topical Medications

These are commonly prescribed for mild to moderate acne:

  • Retinoid creams

  • Benzoyl peroxide

  • Topical antibiotics

  • Azelaic acid

These treatments reduce oil production, bacteria, and clogged pores.

Oral Medications

For moderate to severe acne:

  • Oral antibiotics

  • Hormonal therapy for females

  • Isotretinoin for severe acne

These medications treat acne from within the body.

Advanced Dermatology Procedures

Modern dermatology clinics offer advanced treatments to speed up acne clearance.

Chemical Peels

Medical-grade peels exfoliate the skin and reduce clogged pores.

Laser & Light Therapy

Laser treatments target acne-causing bacteria and reduce inflammation.

Comedone Extraction

Dermatologists safely remove blackheads and whiteheads.

Acne Scar Treatment

If acne has already caused scars, treatments may include:

  • Microneedling

  • Subcision

  • Fractional laser therapy

Simple Tips to Prevent Acne

Daily habits play a crucial role in acne control.

✔ Wash your face twice daily with a gentle cleanser
✔ Avoid squeezing or picking pimples
✔ Use non-comedogenic skincare products
✔ Remove makeup before sleeping
✔ Maintain a balanced diet
