Why do I get white spots on my skin in the summer and how can I treat them? A dermatologist

A Very Important Thing to Know: Pigment Takes Time to Even Out

Here’s something that surprises a lot of people and can lead to unnecessary worry: even after the yeast overgrowth has been successfully treated and is completely gone, the discoloration itself doesn’t disappear overnight. It can take several weeks, and sometimes even a few months, for the skin’s natural pigment to fully even out and blend back with the surrounding tone.

This is a normal part of the healing process, not a sign that treatment failed. Patience is key here — the yeast may be gone quickly, but your skin tone needs time to catch up.

How to Prevent It From Coming Back

Since the yeast responsible for tinea versicolor lives on the skin permanently (just like it does for everyone), it’s entirely possible for the condition to return, particularly during hot, humid months when conditions are most favorable for yeast overgrowth. To reduce the chances of a repeat episode, dermatologists often suggest:

  • Using an antifungal shampoo as a preventive body wash once or twice a month during summer
  • Showering promptly after heavy sweating or sun exposure
  • Wearing breathable, moisture-wicking fabrics in hot weather
  • Avoiding overly oily sunscreens or body products if you’re prone to this condition
  • Keeping skin as dry as possible during high-humidity periods

When Should You See a Dermatologist?

While tinea versicolor is usually easy to self-diagnose and treat, it’s worth booking an appointment with a dermatologist if:

  • The spots are spreading rapidly
  • They’re accompanied by itching, burning, or irritation
  • Over-the-counter treatments haven’t worked after a few weeks of consistent use
  • You’re not entirely sure it’s tinea versicolor, since a few other skin conditions (like vitiligo or pityriasis alba) can look similar but require completely different treatment approaches

Getting a proper diagnosis ensures you’re treating the actual issue rather than guessing — and can save you weeks of using the wrong product.
