Heat rash is such a nuisance! And by the time you have it, applying products can feel really uncomfortable. But it’s no time to get complacent.

The thing is, as your skin experiences this irritation, some products will work better than others. That’s where we come in!

After careful investigation into which sunscreens incorporate the most soothing properties for this concern, SimplySunSafe recommends La Roche-Posay Anthelios Cooling Water Lotion Sunscreen as the best sunscreen for heat rash. It will ensure you remain protected, while offering cool relief.

Caused by excessive sweating in hot and humid environments, heat rash is sometimes unavoidable. And in these times, you’ll be grateful to have a specialized product waiting on your shelf!

Buyer’s Guide

Even considering applying a skin product on top of heat rash can feel uncomfortable. There are a few must-have features that you should search for in your sunscreen to ensure the most pleasant experience possible:

Broad spectrum protection

No matter why you’re searching for sunscreen, you need to be looking for products that provide broad spectrum protection. The reason for this is that broad spectrum sunscreens protect equally against both UVA and UVB rays, which work differently to cause skin damage.

UVB rays damage the outer layer of your skin and cause you to burn your way to a tan. UVA rays are more devious, penetrating the deepest layer of your skin (the dermis), causing premature aging.

Exposure to both types of rays will increase your risk of skin cancer, which is why it’s important to protect against both.

When you have heat rash, not only is your skin more physically vulnerable to the sun, but the UV rays will continue to work just as hard. Luckily, finding sunscreens which provide broad spectrum protection is not all that difficult.

You will learn that they are available virtually everywhere, and you will see that they are quite easy to recognize. Just take a moment to check out the sunscreen’s label and ingredients list.

The label often contains words like ‘broad spectrum’ or ‘UVA/B’ unmistakably indicating the protection you need. You can check out the ingredients list, as well, for zinc oxide, which protects against the full range of UVA/B rays. Any sunscreen with zinc oxide is a great option for protecting skin affected by heat rash!

Best SPF for Heat Rash

You’ve heard many different statements about the Sun Protection Factor (SPF) and which one you should choose. Have you ever taken the time to find out how it really works?

It will help you find the best sunscreen for your, so let me explain it to you:

SPF tells you what fraction of the sun’s rays will reach your skin if you properly apply the product. This means that if you are wearing a sunscreen with an SPF rating of 30, then only 1/30th of the sun’s rays will reach your skin.

That sounds great, right? Well, it is, but make sure you don’t get carried away.

Don’t go outside slathered in SPF 30 and expect to stay in the sun 30 times longer than if you weren’t wearing sunscreen. This is not how it works and that is a sure way to irritate your heat rash!

This is because there are many factors that influence the effectiveness of SPF including the time of day, amount of properly applied sunscreen, and reflections from surfaces like water or sand. (Hint: all of these things reduce its effectiveness.)

Basically you must always remember to reapply at least every two hours, no matter what SPF rating you choose!

But, we still need to decide on one – so… here’s a simple table that will help you understand how much protection you get from different SPF ratings:

SPF Rating UVB Protection
None 0%
2 50%
15 93%
30 97%
50 98%
100 99%

Does this change the way you think about the SPF rating?

So which rating is right for protecting heat rash?

The AAD suggests that you choose sunscreens with SPF ratings no lower than 30 and no higher than 50.

SimplySunSafe agrees with this guideline and recommends products that fall within these brackets.

Physical is better than chemical

Educate yourself about the quality of the products you choose to use. Sunscreens can be grouped into two main categories – chemical and physical.

The difference lies in the active ingredients (and therefore in how work to protect your skin).

Chemical sunscreens soak into your skin and absorb UV rays as they reach your skin. Physical sunscreens reflect UV rays before they reach your skin.

There are abundant reasons to choose physical sunscreens over chemical ones. A few of them are that physical sunscreens:

  • Work immediately upon application
  • Last longer
  • Are less likely to cause irritation
  • Have a longer shelf life

If you’re still not convinced, then listen to this:

Chemical sunscreens often contain ingredients that mess with your hormones. This is not something you want to risk, especially if you are using an antihistamine or cortisone cream for your heat rash.

The worst of these ingredients is called oxybenzone and is surprisingly still legal despite concerns from the EWG. Avoid this ingredient at all costs and…

Stick with a physical sunscreen to protect your heat rash affected skin!

Sensitive skin formula

Heat rash causes discomfort. Whether you find the rash itchy or even painful, you will not want a product to exacerbate the irritation.

Sunscreens designed specifically for sensitive skin are great options. They will be formulated so that they are as gentle as possible, while still providing sufficient protection.

Many sensitive skin formulas also contain skin nourishing and calming ingredients.

The best sunscreen for heat rash prone skin will be designed for sensitive skin.

Water resistant

While water resistance may not be the first thing that comes to your mind when thinking about how to protect your heat rash affected skin, consider this:

Heat rash is largely caused by excessive sweating. So in order to prevent a larger outbreak of heat rash, it will help to use sun protection that is not likely to mix in with your sweat and cause rubbing or irritation.

Sunscreens are made with water resistance for either 40 or 80 minutes. It is up to you to decide which option best suits your needs. Using a sunscreen with 80 minutes of water resistance may lead to less stress in wondering if your sunscreen is still protecting you.

Water resistance is a big help in sunscreen for prickly heat sufferers.

The last product that SimplySunSafe recommends for protecting your heat rash affected skin is Blue Lizard Sensitive. This hearty product provides broad spectrum protection through its active ingredients zinc oxide (10%) and titanium dioxide (5%).

Blue Lizard Sensitive does not provide any water resistance so this is a product that will work best for you if you don’t plan on swimming, and if you will be able to reapply anytime you find yourself sweating.

It is, however, an excellent product. It is recommended by dermatologists and is free of many potential irritants. Blue Lizard Sensitive is gentle enough to use on your face and body and can be used under makeup.

Despite these awesome faetures it comes in last on this list because of the lower concentration of active ingredients and lack of water resistance (although this might make it more suitable for some users).

Give this sunscreen a try and you will see that just a bit will spread over large areas of your skin!

Pros
  • Designed for sensitive skin
  • Pleasant finish
Cons
  • No water resistance

FAQs on Sunscreen for Heat Rash

Q: Does sunscreen irritate heat rash?

A: Sunscreen will not cause further heat rash irritations unless you have an existing skin condition that has become irritated by the environment. Many other causes of heat rash, including overexposure to the sun. There can also be a body’s reaction to sunscreen, as it consists of chemicals. The key is finding one that doesn’t contain harsh ingredients and is made from more natural components. Finding a good, non-irritating sunscreen may be a challenge for some people at first. 

However, give your product time to work its way into your skin. This will give time to your body to absorb some of the active ingredients and formulas without them irritating your skin. 

Q: Does sunscreen stop prickly heat?

A: Prickly heat is a common skin condition that happens when sweat becomes trapped in the hair follicles or pores, leading to an itchy rash of pimples and blotches. So applying sun cream every day can help prevent prickly heat expansion by trapping in moisture and keeping the affected region cool. 

Make sure not to use anti-sweat sunscreens as they may entrap the sweat and cause prickly heat. Also, avoid using sticky sunscreen and skincare that may cause excessive sweating. 

Q: Can waterproof sunscreens cause prickly heat?

A: Waterproof sunscreen contains ingredients like mineral oils and silicone, which can clog pores. Using products with these ingredients suffocates your skin, similar to a cling film. Moreover, it decreases the amount of sweat that usually evaporates from the skin. 

It may cause a prickly heat reaction in people who have sensitive skin. For this reason, it’s important to exfoliate regularly. Besides, use sunscreens that are made from natural pore-friendly ingredients. 

Q: How can you prevent prickly heat rash?

A: The best way to prevent prickly heat is to keep skin dry as much as possible, avoid high levels of perspiration, and increase the use of sun protection. Also, wear loose clothes that are made from cotton and are light on the skin. Your skin will feel cooler with frequent baths with lukewarm water. 

Make sure to get rid of sweat to prevent your sweat glands from clogging. Apart from this, do not exercise in hot and humid weather. Try to use air conditioning to remove heat and humidity. Lastly, use sunscreen to prevent any existing prickly heat rash from worsening.
