Is It Safe to Hit the Sauna After Laser Hair Removal? What You Need to Know

sauna after laser hair removal?

Are you wondering if it’s safe to relax in a sauna after your laser hair removal session? It’s a common question, especially if you’re hoping to unwind after your treatment. While it might be tempting to head straight to the sauna, there are a few important things you should consider first.

In this post, we’ll look at why you might need to hold off on that sauna visit to keep your skin safe and get the best results from your laser treatment. Let’s see what the experts have to say.

Can You Use a Sauna After Laser Hair Removal?

No, it is generally recommended to avoid using a sauna after laser hair removal (LHR).

Laser hair removal works by using a laser to heat up and damage hair follicles to stop hair from growing back. This process heats up your skin a bit too. If you head into a sauna right after, you’re piling on more heat on already sensitive skin.

Think about it: your skin just went through a pretty intense treatment. It’s red, sensitive, and a little stressed out. Adding the heat of a sauna can make your skin feel worse—it can get even redder and more irritated. Plus, sweating in a sauna isn’t just uncomfortable; it can also lead to germs getting into your pores, which are wide open and vulnerable right after treatment.

Many professionals actually use a cold compress and maybe some aloe vera gel to keep you comfortable after the treatment. This helps reduce redness and discomfort and keeps your skin in better condition as it recovers.

So, before you think about stepping into a sauna, let your skin heal and settle. This way, you avoid any extra irritation or potential problems after your treatment.

How Long Should You Avoid the Sauna After Laser Hair Removal?

When it comes to hopping back into the sauna after your laser hair removal, it’s best to hit pause for at least 24 to 48 hours. This cooling-off period helps protect your sensitive skin from extra heat, which can lead to irritation or worse.

  • Scientific Guidance: According to a 2023 review by Godfrey Town, a well-known clinical technologist and laser protection adviser, you should steer clear of heat treatments like saunas for at least 24 to 48 hours post-treatment. This advice is based on solid research and helps ensure your skin isn’t exposed to additional stress that could complicate recovery (Journal of Medical and Clinical Nursing Studies).
  • Laser Clinics United Kingdom echoes this sentiment, recommending that activities such as using a sauna should be avoided for at least 24 hours. This brief break helps your skin start the healing process without the added challenge of excessive heat (Laser Clinics UK).
  • Skin Perfection suggests giving your skin a bit more time—48 hours—before diving into any sauna sessions. They point out that letting your skin cool down naturally during this time can significantly reduce the risk of developing any swelling or redness (Skin Perfection London).
  • Infinity Laser Spa advises playing it extra safe with a waiting period of 7 days. They argue that a full week away from the sauna and similar heat exposures ensures that your skin is thoroughly recovered and ready to handle the high temperatures without any adverse effects (Infinity Laser Spa).

As you can see, while the minimum wait time generally ranges from 24 to 48 hours, stretching this period can be beneficial, particularly if you know your skin tends to react sensitively. Always check in with your laser treatment provider for advice that’s specifically tailored to your situation and skin type. This personalized guidance will help you avoid complications and get the best results from your treatment.

What Happens If You Use a Sauna After Laser Hair Removal?

Deciding to jump into a sauna soon after laser hair removal can lead to some unwanted side effects. While it might sound relaxing, the reality is that the sauna’s heat can do more harm than good for your freshly treated skin.

Potential Risks of Using a Sauna Post-LHR

  • Increased Skin Sensitivity and Irritation: Your skin is already sensitive from the laser’s heat, which targets and damages hair follicles to prevent hair regrowth. Adding sauna heat can irritate your skin even more, causing excessive redness, stinging, or a burning sensation.
  • Risk of Bacterial Infections: One of the biggest concerns with using a sauna after laser treatment is the increased risk of bacterial infections. Saunas are warm and moist environments—perfect for bacteria to thrive. Sweating in the sauna can open pores and allow bacteria to enter, potentially leading to infections like folliculitis, where hair follicles become inflamed and painful.
  • Delayed Healing Process: Heat can hinder the natural healing process of your skin. After laser hair removal, your skin needs time to recover and heal from the stress of the treatment. High temperatures in a sauna can increase blood flow and swelling, which might sound beneficial but can actually slow down the healing process.
  • Exacerbated Swelling and Redness: The heat from a sauna can cause further swelling and extend the period of redness. This is not only uncomfortable but can also affect the overall results of your laser treatment, possibly leading to uneven skin texture or prolonged recovery times.


Stepping into a sauna after laser hair removal might seem like a good idea for relaxation, but it’s better to hold off. The risks of increased irritation, potential infections, and delayed healing are significant enough to warrant patience.

Give your skin the calm, cool environment it needs to recover smoothly and ensure you get the best results from your treatment. Always follow the aftercare advice provided by your treatment specialist, and when in doubt, opt for safer relaxation alternatives until your skin is fully ready to handle the heat.
