The truth about acne

Teenagers and adults alike suffer from acne, and it can have a detrimental effect on your self-esteem at any age. since acne is one of the most common reasons for dermatologist visits, here are the answers to the acne questions I’m asked most, and a few truths to debunk some of the biggest myths.

• What’s the difference between salicylic acid and benzoyl peroxide? Salicylic acid helps exfoliate skin and keep pores clear, while benzoyl peroxide kills the bacteria that cause acne. they help improve acne in different ways and although they can be used together, I often recommending trying salicylic acid first since benzoyl peroxide can be irritating.

•  Does diet affect acne? Preliminary research shows that dairy and sugar may increase acne. but contrary to popular belief, chocolate does not. some doctors believe the iodine in foods like shrimp may lead to acne.

• how should I pop a pus-filled pimple? I try not to advocate picking, but I know sometimes you have to. First, take a hot shower to open pores. then use a sterile needle (boil it for 2 minutes and allow it to cool) and gently prick the center of the whitehead.

• Does my phone cause acne? The bacteria that causes acne (P. acnes) is not spread from person to person, and there is no evidence that cell phones harbor it.

•  how does blue light kill acne? P. acnes bacteria contain a substance called porphyrin that absorbs the blue wavelengths of light and kills the bacteria. Porphyrin isn’t found in other bacteria, which is why blue light doesn’t work for other skin infections.

•  is acne hereditary? I’m going to say probably, but the gene has not be identified yet.

•  how long does it take for acne medications to work? It takes eight weeks for a pimple to form, so you have to give over-the-counter or prescription products that long.
