Acne and acne scar treatment

What causes acne

Acne can be driven by hormones, stress, dandruff, diet, PCOS and family tendency. Most teenagers and many adults face it at some point, and it is one of the most common reasons people visit a skin clinic.

How acne is treated

Almost all acne responds to prescription medicines. Your dermatologist may add salicylic acid peels, peels for pimple marks, and sometimes laser. Treatment usually lasts 3 to 6 months depending on severity and location, and the plan needs to be followed fully. You will also get diet guidance to help prevent new breakouts.

Acne scars

Scars form when acne is left untreated and inflames deeper skin layers. Scars come in different types, so the plan is chosen after examination. Fractional CO2 laser is one of the most effective options. Others include dermaroller, chemical peels and fillers.

Options your dermatologist may use

• Prescription creams and oral medicines
• Salicylic acid and other peels
• Peels for post-acne marks
• Fractional CO2 laser for scars
• Dermaroller and fillers for selected scars

Grades of acne

Mild acne shows as blackheads, whiteheads and a few pimples, and often responds to creams. Moderate acne has more inflamed pimples and may need oral medicines. Severe acne with painful nodules or cysts needs early treatment by a dermatologist, because it is the type most likely to leave scars.

Daily care that helps

Wash your face twice a day with a gentle cleanser, use a non-comedogenic moisturiser and sunscreen, and avoid squeezing pimples. Change pillow covers often. Do not apply toothpaste, lemon or steroid creams to pimples, as they can irritate the skin or make acne worse.

Does diet affect acne?

In some people, high-sugar foods and dairy may worsen acne. Diet alone rarely clears it, but it can help alongside treatment.

Is acne treatment safe in pregnancy?

Some acne medicines are not safe in pregnancy. Tell your doctor if you are pregnant or planning to be, so safe options are chosen.
