Can Sweat Cause Pimples and Acne?

Can sweat cause pimples and acne? Do you really feel like you get zits when you work out or when the weather turns humid? It's possible and the type of acne that happens when you are sweaty is called Pityrosporum folliculitis. I see a lot of this type of sweat-induced acne in my dermatology practice, especially during the summer when my patients are hot and sweaty from enjoying the outdoors.

Sweating can cause acne.

This kind of acne also happens during the school year when athletes are training and competing in various sports.

Pityrosporum folliculitis is a tough and stubborn form of acne to treat because some people’s skin is just prone to it. 

The reason is that this yeast is a normal skin yeast that grows on almost everybody's skin. Also called Malassezia, it starts to overgrow in the pores when the conditions are right. Some people's pores don’t fight the yeast very well so it easily takes off.  A little heat and sweat, and poof, the yeast "parties on" causing pimples.

What is the best treatment for Pityrosporum folliculitis type of acne?

dermatologist's treatment for sweat caused pimples and acneThe treatment of this type of acne depends on how severe the acne is and what part of the skin is involved.  I always recommend an anti-yeast cleanser for my patients. My favorite ingredient for that is pyrithione zinc. This cleanser needs to be used every day to help suppress yeast "happiness" and overgrowth. Yeast also thrives in clogged pores so I like to combine pyrithione zinc with keratolytic product that busts blackheads and clogged-pore debris. The best choices depend on a person’s skin type and skin sensitivities because keratolytic ingredients can be irritating. 

My "go to" keratolytic ingredients are benzoyl peroxide, salicylic acid and glycolic acid. Benzoyl peroxide will also treat the acne bacteria called P. acnes that can help the Pityrosporum yeast create pimples. They are a great team of collaborators for sweat acne.

I also use physical exfoliation with a slightly rough shower sponge or scrub. If money is no object, I also recommend a Clarisonic Brush to keep pores really free from pore clogging oil and debris.

What does Pityrosporum folliculitis look like?

This type of acne manifests with itchy and tender, red pimples and little, clogged white bumps. The lesions:

  • Are situated along the hairline and jawline of the face, often covering the entire forehead, too;
  • Run down the sides and back of the neck; and 
  • May also involve the upper chest and back, and sometimes, they go all the way down the back to the waistline.

What are the best home treatment remedies I use in my dermatology practice for sweat acne from Pityrosporum folliculitis?

You need to control yeast, reduce acne causing bacteria, unclog your pores and prevent scarring from hyperpigmentation.

Doctor's additional tips for getting rid of Pityrosporum folliculitis sweat acne.

  1. It is important to wash off sweat and oil from your skin as soon as possible after sweating.  If you can’t wash right away, then degrease the skin with my Acne Treatment Pads or Naturally Hydrating Pore Minimizing Toner and a cotton pad. Keep one of these products in your gym bag or backpack.  
  2. Sun protection is important to prevent hyperpigmentation of healed acne lesions. This is best provided by wearing UPF 50 sun protective clothing until the acne has healed. 

Does diet help Pityrosporum folliculitis type of sweat acne?

Maybe. There is no scientific evidence for this – yet. But, in my dermatology practice, I see that when my Pityrosporum folliculitis patients eat a mostly healthy diet with more fruit and veggies, and less junk food and sugar, their skin rewards them with fewer yeasty pimples. We know that yeast always love sugar and grease so taking away the feast seems to quiet the "yeasty party in the pores."

Are there treatments that can help when the acne is severe and doesn't respond to home treatment?

Yes, they require a doctor's supervision and prescription. Pulsed therapy with oral anti-fungals can be helpful, but there are side effects and so the decision is not to be considered lightly. I always start with the skin care that I outlined above, and it becomes a long-term skin care regimen for yeast suppression in Pityrosporum-folliculitis-prone individuals.
