Why Does My Skin Break Out More in the Summertime?
Summer’s heat and humidity can have a significant impact on your complexion — especially when you struggle with acne. Here, learn how seasonal factors affect oil production and what you can do to keep warm-weather flare-ups at bay.

Does it seem like your breakouts get worse during the summer months? You’re not imagining things. While the warmer weather has plenty of perks, it can also aggravate your acne.

At Shady Grove Dermatology, we help patients in and around Rockville, Maryland, maintain blemish-free skin through every season. Our providers work with you to pinpoint your acne triggers and build a personalized plan that meets your needs.

According to one study, nearly 50% of people with acne experience seasonal changes in their symptoms. Read on to find out why your skin acts up in the summertime.

Understanding summer breakouts

Acne develops when excess oil and debris clog your pores, trapping bacteria under the skin. As these bacteria multiply, they trigger inflammation, which can lead to pimples, pustules, and deep, painful cysts.

Breakouts can happen at any time of year, but certain seasonal factors make them more common — and often harder to manage — during the summer months.

Increased sebum and sweat

Your skin produces oil (sebum) to maintain its moisture barrier and protect itself from environmental damage. When temperatures rise, production naturally increases and makes acne more likely.

Sweat mixes with this excess sebum to create a sticky film that can easily clog pores and contribute to breakouts. High humidity makes matters worse by preventing evaporation, allowing moisture and oil to linger on your skin for longer periods.

Facial friction

In addition to SPF, accessories like hats, visors, and sunglasses provide an important extra layer of sun protection in the summer. But when these accessories rub against warm, sweaty skin, they create friction and irritation that often leads to a type of breakout known as acne mechanica.

Dehydration and dryness

Though breakouts are typically associated with too much moisture, dehydrated skin is also a trigger for many people. Not drinking enough water, spending too much time in the sun, and dry indoor air can strip moisture from the skin, disrupting its natural balance.

In response, your sebaceous glands begin to produce more oil to compensate for the moisture loss, creating the ideal conditions for acne to flare up.

Keeping your skin clear throughout the summer months

Summer breakouts can be frustrating, but a few simple changes to your routine can significantly reduce their frequency and severity. Here’s what you can do to protect your skin and keep blemishes at bay all season long.

Wash away sweat, dirt, and oil

Washing your face immediately after workouts and outdoor activities helps remove impurities like sweat, excess oil, and other debris before they accumulate in your pores. But more isn’t always better. Harsh cleansers and aggressive scrubbing can disrupt your skin barrier and cause irritation.

Choose lightweight, noncomedogenic products

The rich, heavy moisturizers that seal in moisture during the winter months can trap sweat and oil against your skin in the summer heat. Swap them out for lightweight, noncomedogenic options, which hydrate skin without clogging pores.

Daily SPF is essential, but the wrong formula could worsen your acne. To protect your skin without triggering a breakout, use an oil-free sunscreen formulated specifically for the face.

Stay hydrated

Drinking plenty of water throughout the day helps regulate your skin’s moisture levels and supports your overall cellular health. When your skin is properly hydrated, it’s less likely to overproduce oil in response to dryness.
