Why Summer Can Make Rosacea Worse (And What You Can Do About It)

For many people, summer is a season to enjoy sunshine, holidays and spending more time outdoors. However, if you have rosacea, warmer weather can often mean increased redness, flushing and uncomfortable flare-ups.

Rosacea is a long-term inflammatory skin condition that most commonly affects the cheeks, nose, chin and forehead. Although there is currently no cure, understanding your triggers and receiving the right treatment can help keep symptoms under control.


Why does hot weather trigger rosacea?

Heat causes blood vessels near the surface of the skin to dilate. For those living with rosacea, this often leads to increased redness and flushing.

Some of the most common summer triggers include:

  • Hot weather
  • Direct sunlight and UV exposure
  • Humidity
  • Alcohol
  • Spicy foods
  • Hot drinks
  • Stress
  • Vigorous exercise

Not everyone experiences the same triggers, so keeping a diary of flare-ups can help identify what affects your skin.


How to protect your skin during summer

There are several simple ways to reduce the risk of flare-ups:


Wear sunscreen every day

Daily sun protection is one of the most important steps in managing rosacea. Choose a broad-spectrum SPF 50 sunscreen suitable for sensitive skin and remember to reapply regularly throughout the day.


Keep your skin cool

Seek shade during the hottest part of the day, wear a wide-brimmed hat and use cool compresses if your skin begins to feel hot or irritated.


Choose gentle skincare

Avoid harsh exfoliants, fragranced products and alcohol-based toners that can aggravate sensitive skin. Instead, opt for gentle cleansers and moisturisers designed for reactive skin.


Stay hydrated

Drinking plenty of water can help support healthy skin, particularly during periods of hot weather.
