Sunburn is a painful reminder of how strong the sun’s rays can be. While some redness and irritation are unavoidable after too much sun, many people want to know how to heal more quickly. Red light therapy, which is often used in skin care, may be the answer. But does red light therapy help sunburn? We’re going to look at how this therapy works and how it could help your sunburnt skin.
Understanding Sunburn
Sunburn happens when your skin is exposed to too much UV radiation from the sun. This damages the skin cells and causes inflammation. The redness and pain are your body’s way of telling you something isn’t right. Some people might feel a bit sore, but others could get skin that peels or blisters.
Short-Term Effects of Sunburn
In the short term, sunburn can cause redness, swelling, and a burning sensation. These symptoms often appear within a few hours of exposure and can last for several days. The discomfort can range from mild irritation to quite severe, making even the simplest tasks feel challenging.
Long-term effects of repeated sunburnRepeated sunburn can lead to more serious skin problems, including premature ageing (wrinkles, spots, and loss of elasticity), and even an increased risk of skin cancer. This is a reminder that we need to take care of our skin, not just when we have sunburn but in the long run, too.
What is red light therapy?
How Red Light Therapy WorksRed light therapy uses low-level wavelengths of red light to go into the skin. This stimulates the skin to repair itself, reduces inflammation, and promotes healing. The idea is simple: the light triggers the body’s natural processes to speed up recovery and improve skin health.
Types of Red Light Therapy Devices
There are various devices available for red light therapy. You’ll find handheld units, panels, and even full-body beds. Red light therapy beds are particularly good for treating large areas of skin at once, which makes it ideal for overall skin rejuvenation.
Popular uses of red light therapy include treating acne, wrinkles, and wound healing. It’s also becoming popular for treating pain and inflammation. It is relatively new for treating sunburn, but more and more people are discovering how it can help with sun-damaged skin.
How Red Light Therapy Helps Sunburn?
One of the most immediate benefits of red light therapy for sunburn is its ability to reduce inflammation. Sunburn makes the skin swell and go red, which can hurt. Red light therapy can help with this by increasing blood flow to the area and speeding up the healing process.
It also helps the skin to heal. Sunburn causes skin cells to break down and become damaged. Red light therapy helps the skin to repair itself by increasing collagen production, which is really important for the skin to regenerate. This speeds up the recovery process, helping you feel better sooner.
Alleviating Pain and Discomfort
Sunburn can cause a lot of discomfort, which can make everyday activities feel unbearable. Red light therapy can help with this pain by increasing blood flow and reducing swelling. The light goes deep into the skin, which makes you less sensitive to pain and reduces the burning feeling.
It also boosts collagen production, which is important for keeping the skin firm and youthful. When your skin is sunburned, it’s damaged and loses some of its natural collagen. Red light therapy can help your skin to produce more collagen, which can repair the skin’s structure. This helps restore the skin’s natural elasticity and reduces the appearance of sunburn marks.
Scientific Evidence Supporting Red Light Therapy for SunburnKey Studies on Red Light Therapy and Skin HealingSeveral studies have shown that red light therapy can speed up the healing of skin tissue. One study, which was published in the Journal of Photochemistry and Photobiology, found that red light therapy helped to reduce inflammation and speed up healing in patients with skin injuries. While there is still more research to be done on red light therapy for sunburn, the studies that have been done so far show that it can generally help treat skin damage.
What Experts Think
Experts think that red light therapy could be really important for sunburn recovery. According to skin doctors, red light therapy has been shown to improve skin conditions by reducing inflammation and increasing collagen production. Many people are hopeful that it can help with sunburns.
Best Practices for Using Red Light Therapy on Sunburn
When should you start treatment?
The best time to start using red light therapy for sunburn is when you see the first signs of redness. The earlier you start, the better.
How long should you do it for and how often?
To get the most out of red light therapy, do short sessions (10-15 minutes) a few times a week. If you’re using a device at home, be sure to follow the manufacturer’s instructions regarding the duration and frequency of sessions to avoid overuse.
Safety Precautions
Red light therapy is generally safe, but there are a few things to consider. If you have extremely sensitive skin or open blisters from sunburn, avoid using red light therapy on those areas until the skin has healed slightly.
Other ways to treat sunburn
You can buy creams and lotions with aloe vera or hydrocortisone to put on the affected area. These creams can provide immediate cooling relief and help moisturise the skin.
Natural RemediesYou can also use natural remedies to help with the discomfort of sunburn. These include cool baths, green tea and cucumber slices. But they only provide temporary relief. Red light therapy can promote long-term healing.
Hydration and Nutrition TipsSunburn can dehydrate the skin, so it’s important to drink plenty of water. Eating foods rich in antioxidants, such as berries and green vegetables, can also help support skin healing from within.
The best way to use red light therapy with other treatments is to use them together. This can make recovery faster. The cream cools the skin, while red light therapy works deeper to promote healing at the cellular level.
It can also help your skin stay moisturised. This is important for sunburn recovery, as dry skin can slow down the healing process.
It can also help to reduce the risk of peeling, which can be both uncomfortable and unsightly. Red light therapy can help to reduce the chance of this peeling happening, so your skin will look and feel better more quickly.
Choosing the Right Red Light Therapy Device for Sunburn
If you have small, localized areas of sunburn, handheld red light therapy devices are a great choice. They allow you to focus on specific spots where the sunburn is most intense.
Panels and Beds for Larger Areas
For more extensive sunburns, full body red light therapy beds or panels can treat larger sections of the body at once. These are ideal for sunburns covering a wider area, such as your back or legs.
Key Features to Look For
When selecting a red light therapy device, look for one with the right wavelength (around 600-650 nm for red light) to ensure optimal effectiveness for skin healing.
Possible risks and limitations of red light therapy for sunburn
Mild side effects
Red light therapy is usually safe, but some users may experience mild side effects, such as temporary redness or tingling in the skin. These effects usually go away after a few hours.
When to Avoid Red Light Therapy
If your sunburn is severe, with blisters or open wounds, it’s best to avoid using red light therapy until the skin has started to heal. If you are unsure, it is best to consult a healthcare professional.
Red light therapy is not a substitute for sun protection. Always use sunscreen and protective clothing to prevent sunburn in the first place.
Conclusion
Red light therapy shows promise in helping treat sunburn by reducing inflammation, promoting healing, and alleviating discomfort. While it isn’t a cure-all, it can certainly help you recover more quickly when used alongside other treatments. So, next time you have sunburn, try adding red light therapy to your recovery plan—it might just help your skin.
