Key Takeaways
Red light therapy helps heal skin, reduce inflammation, and boost collagen, without tanning your skin.
Tanning beds use UV light to tan your skin but increase the risk of skin cancer and accelerate aging.
Red light therapy is safer, with no UV radiation and fewer risks, while tanning beds can cause DNA damage.
Red light therapy can improve skin texture, speed up muscle recovery, and reduce inflammation, with long-lasting benefits.
Tanning beds offer temporary skin improvement and vitamin D boosts but should be used cautiously due to health risks.
Briefly introduce red light therapy and tanning beds
- Red light helps your skin feel better, not look tanned: Red light therapy uses gentle red or near-infrared light that goes deep into your skin. It helps with healing, reduces inflammation, and boosts collagen. But it doesn’t change your skin color or give you a tan.
- Tanning beds change your skin color, not its health: Tanning beds use UV rays to make your skin darker by increasing melanin. This is your body’s way of protecting itself from the sun, but it doesn’t help your skin heal or improve its condition.
- Red light works inside the skin, tanning beds stay on the surface: Red light therapy reaches deeper layers of your skin to repair and refresh it. Tanning beds only affect the top layer , giving it a tan without any health benefits underneath.
- One is made for healing, the other is made for looks: The purpose behind red light therapy is to improve skin health from the inside. Tanning beds are built to change how your skin looks by making it darker, they’re all about appearance.
- Red light gives benefits, tanning beds give color: At the end of the day, red light therapy supports your skin’s health , while tanning beds are just a way to get a tan . One is about making your skin better, the other is about making it browner.
Quick Summary:
Red Light Therapy: Uses red/near-infrared light to heal skin, boost collagen, and reduce inflammation.
Tanning Beds: Use UV light to tan skin by increasing melanin production.
Main Difference: Red light heals; tanning beds darken skin.
Important: They may look similar, but their purposes and effects are completely different.

Key Differences Between Red Light Therapy and Tanning Beds
Wavelength of Light
- Red light uses a safe part of the light spectrum: Red light therapy works with light between 620 to 750 nanometers , which is gentle, visible, and doesn’t harm your skin.
- Tanning beds use stronger, invisible light that can harm skin: Tanning beds emit UV light between 280 to 400 nanometers , which is invisible to the eye and much more intense on the skin.
- How the light affects your skin depends on its wavelength: Because of the type of light used, red light therapy helps heal the skin , while tanning beds can cause skin damage and long-term problems .
Purpose
- Red light therapy is meant to repair your skin, not change its color: The purpose of red light therapy is to help your skin heal naturally and boost collagen, which makes the skin look healthier over time, not darker.
- It’s used to calm down skin problems like acne and wrinkles: This therapy is known to reduce inflammation , which helps clear up common skin issues like breakouts, scars, and fine lines.
- Tanning beds are designed only to make your skin look darker: Tanning beds use UV light to give your skin a tanned look by increasing melanin. That’s their only job, they don’t help your skin get healthier.
- Tanning affects only the top layer of your skin and stops there: The tan from a tanning bed stays on the surface and doesn’t go deeper. There are no added skin benefits besides a temporary change in color.
- One is for healing, the other is just for looks: In short, red light therapy helps your skin heal and improve over time, while tanning beds simply change how your skin looks without helping it get healthier.
Skin Cancer Risk
- Tanning beds raise your chances of getting skin cancer: Using tanning beds exposes your skin to harmful UV rays, which sharply increases your risk of developing skin cancer.
- UV light harms your skin at the DNA level: The UV radiation from tanning beds damages the DNA in your skin cells, which can lead to dangerous changes that cause cancer over time.
- Starting tanning young makes the risk even worse: People who begin using tanning beds early in life face a much higher chance of getting skin cancers like basal cell carcinoma, squamous cell carcinoma, and melanoma.
- Tanning before age 35 pushes melanoma risk way up: If you use tanning beds before the age of 35, your chances of developing melanoma can jump by as much as 75% .
- Getting a tan from UV light always means skin damage: According to skin experts like Dr. Rachel Abbott , tanning beds damage your skin even if it looks healthy on the outside, because the damage starts deep in the cells.
- Red light therapy doesn’t carry the same cancer risk: Unlike tanning beds, red light therapy doesn’t use UV rays and doesn’t increase the risk of skin cancer, making it a much safer option.
- Red light therapy is usually safe if you’ve had skin cancer: Even people with a history of skin cancer can often use red light therapy safely, but it’s smart to ask a doctor before starting.

Aging Effects
- Tanning beds make your skin age faster than normal: UV rays from tanning beds break down the skin’s building blocks like collagen and elastin. This causes wrinkles, loose skin, and age spots much earlier than they would naturally appear.
- Red light therapy helps your skin stay young and firm: Instead of harming your skin like UV tanning, red light therapy helps it produce more collagen. This keeps your skin tighter, smoother, and reduces visible signs of aging.
- Using the right skincare with red light makes aging signs fade even more: When you combine red light therapy with serums that have ingredients like hyaluronic acid, peptides, or vitamin C, the results are even better, your skin gets more hydrated, firmer, and looks fresher and brighter.
- Tanning dries your skin, but red light therapy keeps it soft and healthy: Tanning beds strip your skin of moisture, making it dry and tired-looking. Red light therapy does the opposite, it hydrates, repairs, and brings back a healthy glow.
Treatment Duration
- Red light therapy sessions take more time than tanning beds: A typical red light therapy session lasts 10 to 20 minutes , which is longer than a tanning bed session that usually takes just 5 to 10 minutes .
- You can use red light therapy more often than tanning beds: Because red light therapy is gentle on the skin , it can be used several times a week . On the other hand, tanning beds use UV rays , so it’s safer to limit them to once or twice a week .
- Red light therapy takes longer to show results but lasts longer: It might take about three weeks of regular red light therapy to see visible changes, but the skin improvements last longer and are healthier over time compared to the faster but short-term effects of tanning.
Mechanism of Action
- Red light helps your cells make more energy: Red light therapy works by activating the mitochondria inside your cells. These tiny parts act like energy factories and start producing more ATP, the fuel your cells need to repair themselves and work better.
- This kind of light helps your body heal without hurting it: Red light uses visible light that doesn’t include UV rays, so it doesn’t damage your skin or DNA. Instead of harming your body like UV light can, red light supports healing and reduces inflammation.
- UV light in tanning beds makes your skin darker by producing pigment: Tanning beds work by sending out UV rays that tell special skin cells (called melanocytes) to make more melanin, which gives your skin a tan.
- The light from tanning beds can damage your skin over time: Unlike red light, UV rays from tanning beds can harm your skin’s DNA, increase the risk of skin aging, and even lead to skin cancer. That’s why red light is seen as a much safer option.
FDA Classification
- Red light therapy is officially seen as low-risk by the FDA: The FDA puts red light therapy devices in the Class II low-risk category , meaning they are considered safe for general use. Many are cleared for both at-home and professional use.
- These light devices get approved by comparing them to older safe devices: Red light therapy devices usually go through the 510(k) clearance process , where they must prove they are similar to already-approved devices. This makes the FDA approval quicker but still reliable.
- Tanning beds are treated as more dangerous by the FDA: Because of health risks like skin damage and cancer, tanning beds fall into higher risk classes (Class II or III) and are tightly regulated, especially when used by minors.
- Many countries have strict rules to protect people from tanning bed risks: Outside the U.S., governments have placed heavy restrictions on tanning bed ads and often require salons to give clear health warnings. These laws vary but show a global effort to limit harm.
- Tanning beds have no medical approval or health benefits: The FDA does not recognize tanning beds for any medical purpose . They’re only used for cosmetic tanning and offer no approved therapeutic value like red light therapy does.
Summary:
Red light therapy heals and rejuvenates your skin without damage, while tanning beds tan by causing harm through UV exposure. If you're looking to boost skin health safely, go for red light. If you want a tan, know the risks first.

Benefits of Tanning Beds
Boosts Vitamin D Production
- Tanning beds help your body make vitamin D, which keeps your bones strong: Tanning beds give off UVB rays that help your skin produce vitamin D. This vitamin is important for keeping your bones healthy and strong.
- Millions of Americans still use tanning beds to get their vitamin D: Even though fewer people are tanning now, about 7.8 million adults in the U.S. still use tanning beds every year, partly to maintain vitamin D levels and appearance.
- Many teenagers around the world still use tanning beds for light and vitamin D: From 2013 to 2018 , about 6.5% of teenagers globally used tanning beds, showing that young people also turn to indoor tanning, possibly for the same health or appearance reasons.
- Some people say tanning helps their skin look better and more even: Tanning beds may temporarily make skin look clearer by reducing the look of blemishes, scars, or uneven skin tone, which some believe adds to the health glow.
- Getting some UV light from tanning can lift your mood and make you feel good: The UV light from tanning beds can boost serotonin, a chemical in your brain that helps improve your mood and make you feel relaxed and happier.
Improves Skin Appearance
- A light tan can make your skin look naturally healthier: Tanning beds can give your skin a warm, sun-kissed glow that many people feel makes them look more vibrant and attractive.
- Tanning can hide marks and make your skin look more even: If you have scars, acne marks, or uneven patches, a tan can help blend them in so your skin tone looks smoother and more balanced.
- Some skin problems may look better for a short time after tanning: Conditions like rosacea or vitiligo might look less noticeable for a little while because of the UV light exposure from tanning beds.
- Over time, tanning makes your skin look older, not better: Even though tanning may look good at first, doing it often can lead to wrinkles, dark spots, and rough skin that take away from your appearance later on.
Enhances Mood
- Tanning beds make you feel better by boosting happy chemicals: Exposure to UV light from tanning beds helps your body release endorphins, natural feel-good chemicals that lift your mood and make you feel more positive.
- More serotonin from UV light can help you stay in a good mood: Using a tanning bed also increases serotonin levels in the brain, which plays a big role in keeping your emotions balanced and boosting your overall happiness.
- The warmth from tanning beds helps you feel calm and relaxed: The cozy warmth and gentle light create a peaceful atmosphere that helps release tension, calm your mind, and reduce daily stress.
- Light from tanning beds can help your body relax naturally: UV light exposure helps trigger certain hormones that encourage your body to relax, adding to a feeling of comfort and peace.
- Tanning beds can lift your mood but can’t replace therapy: While tanning beds can make you feel better temporarily, they are not a solution for mental health issues and shouldn’t take the place of professional care.
Supports Better Sleep
Tanning beds can help improve sleep quality by influencing melatonin production. Melatonin is the hormone that regulates your sleep-wake cycle, and exposure to UV light from tanning beds can increase its levels. This can make falling asleep easier and improve the overall quality of rest.
Summary:
Using tanning beds may boost your vitamin D, improve skin appearance, lift your mood, and help you relax or sleep better. But remember, while they offer short-term benefits, it’s important to use them carefully to protect your skin’s health.
