Can Sweat Cause Pimples and Acne?

Can Sweat Cause Pimples and Acne?

Sweating can cause acne.

It happens when you are in a hot and humid climate or from exercising and working out. ThisSports and fitness type of acne 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.

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?

The 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.

Because clogged pores and oily skin also seem to give the yeast cause for celebration, I like to combine pyrithione zinc with a 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" ingredients are benzoyl peroxide, salicylic acid and glycolic acid. I also use physical exfoliation with a slightly rough shower sponge or scrub. If money is no object, I recommend a Clarisonic Brush, too.

Now the details.

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.

doctor's advice for complete skin care for rosaceaWhat are the best home treatment remedies for pityrosporum folliculitis type of acne from my dermatology practice?

The best results come when you create a complete skin care routine built from the four key steps in skin care:

Cleanse + Correct + Hydrate + Protect

In the case of Pityrosporum Folliculitis, your cleanse and correct steps may be achieved together by your medicated cleanser! If you have really stubborn acne, you may want to apply a leave-on product to enhance the "correct" step. 

Treatment recommendations of pityrosporum folliculitis acne involving the face:

This is the best toner for sensitive skin and to have glowing skin for your wedding day! Wash your skin as soon as possible after sweating.
If you can't wash right away, then remove facial oil
with the Acne Treatment Pads listed below or
with a natural witch hazel toner.

best face cream for all skin types with rosacea

Hydrate dry skin to prevent irritation with a light and oil-free moisturizer.

My top choice for pityrosporum folliculitis acne is Daily Face Cream for Normal to Oily Skin.

Wearing sunscreen is important because pityrosporum folliculitis tends to hyperpigment where pimples have healed. Apply sunscreen last on top of moisturizer.

My top choices of sunscreen include:

best matte mineral zinc oxide sunscreen for oily skin and makeup primer  Sheer Strength Matte Tinted Sunscreen with it's lovely dry and
oil-absorbing formulation.
best all purpose broad spectrum daily sunscreen for face EltaMD Clear Sunscreen

Treatment for pityrosporum folliculitis involving the neck, back and chest:

Wash as soon as possible after sweating.  If you can’t wash right away, then degrease the skin with the Acne Treatment Pads or Witch Hazel Toner.

Every day in the shower, use a physical exfoliation with a slightly rough shower sponge or cloth to help exfoliate thick back skin. Exfoliate the chest, too, but use only gentle pressure. You can do this with Salux Cloth, a Buf Puf Body Sponge.

Alternate your cleansers to both cleanse and correct in one step. Use a foaming pyrithione zinc cleanser such as Foaming Zinc.

Alternate with one of the keratolytic cleansers above that you are using on your face including either the Foaming Acne Treatment Cleanser, the Foaming Benzoyl Peroxide Cleanser or the Glycolic Acid Face and Body Wash.

My Ultimate Acne Solutions Kit plus the Calming Zinc will work for the face.

best products to fight back and chest acne

My Back Acne Kit will work on the back. It even comes with the Salux Cloth. 

Hydration of back and chest skin will come naturally as your skin produces oil. 

Sun protection is important to prevent hyperpigmentation of healed acne lesions. This is best provided by wearing 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.
