Acne Q&A: Ask the Dermatologist


Q: What Causes Acne?

A: While the detailed mechanism of acne is not well known, acne is the result of hormonal, bacterial, and inflammatory disturbances. Due to overactive sebaceous glands, pores become clogged with excess oil, prompting the proliferation of acne bacteria. This can inflame the skin, resulting in pimples or cysts.

Q: Should I squeeze out my acne?

A: Definitely not. Squeezing or picking pimples will increase inflammation, and can lead to scarring. Allow the pimples to heal naturally. For more tips on skincare, visit

Q: Why is there a red mark after the pimple has subsided?

A: This is a common post-inflammatory change, and will disappear in 6 to 12 months. Do not pick or otherwise aggravate the scabs as it will only make recovery slower.

Q: Does long hair affect acne?

A: Maybe. Long hair that is in contact with your face can aid acne breakouts due to the excess oil at the end of the hair. If you have long hair, shampoo daily, keep your hair away from your face, and take care in applying hairstyling products, and keep them away from your skin.

Q: How do acne cleansers work?

A: Acne cleansers can benefit you by removing excess oil, makeup, sweat, and dirt from the skin’s surface. This can help the skin absorb other acne treatments easier. As with any product, excessive use can aggravate your skin by drying it out, so make sure that you read the label for proper use.

Q: What about foundations?

A: Foundations and other cover-up products can help hide your acne, but make sure that they are oil free, as these can aggravate your acne. Many products are labelled non-comedogenic, or non-acnegenic.

Q: What about topical creams?

A: Topical creams like tretinoin encourage collagen production, helping smooth out your skin as well as treating acne scars.

Q: Should I just wait for acne to go away?

A: Acne doesn’t just affect us physically. It can have impacts that are less visible, such as anxiety, depression, and social withdrawal in some cases. If you are suffering from acne, seek treatment as soon as possible. Your dermatologist can help find a solution that works for you. For more skin tips visit
