[The Effects of Lighting on Skin] Besides UV, does indoor lighting also affect skin pigmentation and wrinkle formation?

Hello.

The beginning of natural beauty,

A clinic that provides care 365 days a year,

"Bellevue Clinic."

Spring has finally arrived in full. It’s time to take your padded coat to the dry cleaner and bring out your spring clothes. On a warm, sunny day, applying sunscreen carefully before going out is now such a natural routine. But have you ever thought about this?

"I don’t go out much,

and I mostly stay indoors,

so I don’t have to worry about my skin being damaged by UV rays?"

"Light from fluorescent lamps at home or in the office

probably won’t have a big effect on the skin...

UV rays are the problem."

"Is that really true?"

Today, at Bellevue Clinic, we have prepared a clear answer to the question many people are curious about: "Besides UV, does indoor lighting also affect skin pigmentation and wrinkle formation?" If you have felt safe indoors, please pay attention to today’s post!

Does indoor lighting also affect skin pigmentation and wrinkle formation?

Yes, it does. Many people overlook the fact that the harmful effects of indoor lighting on skin health are just as important as UV rays. While the importance of sunscreen outdoors is always emphasized, the lighting environment indoors can also affect skin pigmentation and wrinkle formation. In this article, we will look at the various effects indoor lighting has on the skin and learn how to maintain skin health.

What is the light around us?

The light we encounter in daily life consists of various wavelengths. Among them, the one that has the greatest effect on the skin is ultraviolet (UV). But there is another type of light that is easy to overlook: light in the visible light range. In particular, studies are increasingly showing that blue light or high-energy visible light (HEV) may affect the skin.

Blue light, everywhere?

Blue light is included in sunlight, but it is also emitted in large amounts from fluorescent lights, LED lights, and electronic device screens such as smartphones, computers, and TVs, which we mainly use indoors. For modern people who spend all day indoors and then continue using smartphones or watching TV after work, exposure to blue light is at a level that cannot be ignored.

🤔 So, is indoor lighting really harmful to the skin?

Well, this is probably the part you are most curious about. To get straight to the point, indoor lighting, especially blue light, can affect skin pigmentation and wrinkle formation. Of course, the degree of its effect may be smaller than that of UV rays, but it is important to remember that long-term, consistent exposure can have negative effects on the skin.

🤔 How does blue light affect the skin?

1> Causes pigmentation: Especially for people with darker skin tones, prolonged exposure to blue light can stimulate melanocytes and cause or worsen pigmentation such as melasma, freckles, and blemishes. You can think of it as a similar process to skin tanning after long exposure to sunlight.

2> Damage to the skin barrier and increased reactive oxygen species: Blue light can penetrate deep into the skin and promote the production of reactive oxygen species. These reactive oxygen species can damage skin cells and destroy elastic fibers such as collagen and elastin, which can accelerate skin aging and contribute to wrinkle formation.

3> Dryness and reduced elasticity: Some studies have also reported that blue light can weaken the skin barrier function, causing the skin to become dry and reducing elasticity.

☀️ UV rays vs. blue light — which is more serious?

Of course, ultraviolet rays are still the main cause of skin aging and skin cancer. UV rays directly damage DNA in the skin and strongly accelerate the breakdown of collagen and elastin, leading to deep wrinkles and sagging skin. But that does not mean we should ignore the effects of blue light. Although its energy is weaker than UV rays, experts say that the cumulative effect cannot be ignored because we are exposed to blue light indoors for much longer periods of time. In particular, as recent use of electronic devices such as smartphones and computers has increased, exposure to blue light is also on the rise.

🔬 What the research says

Through various studies, the effects of blue light on the skin have been identified. Some studies have shown that blue light at certain wavelengths significantly increases melanin production, while others have found that exposure to blue light can increase reactive oxygen species in skin cells and cause oxidative stress. Although more research is still needed, these findings suggest that blue light emitted from indoor lighting and electronic devices cannot be considered completely safe for our skin.

🛡️ How can you protect your precious skin from indoor lighting?

How can you protect your precious skin from indoor lighting? Here are a few simple yet effective methods.

1> Apply sunscreen indoors as well: It is a good idea to apply sunscreen carefully indoors, not only to block UV rays coming through windows but also to block some visible light.

In particular, mineral sunscreens containing zinc oxide or titanium dioxide can also provide some visible-light blocking effect. Recently, using tone-up sunscreens or makeup products containing iron oxide, which is known to help block blue light, has also become a good option.

2> Reduce electronic device use: It is best to reduce the time spent exposed to blue light from electronic devices such as smartphones, computers, and TVs as much as possible. In particular, avoiding device use before going to sleep helps not only skin health but also sleep health.

3> Use blue-light-blocking filters: You can reduce blue light exposure by attaching blue-light-blocking filters to electronic devices such as smartphones and computers, or by enabling the relevant settings.

4> Be mindful when choosing lighting: If possible, use incandescent bulbs or warm-toned lighting, and avoid prolonged direct exposure under fluorescent or LED lights that emit a lot of blue light.

5> Use cosmetic products with antioxidant ingredients: Using cosmetics rich in antioxidant ingredients such as vitamin C, vitamin E, and polyphenols can help suppress reactive oxygen species in the skin and prevent skin cell damage.

😌 Things worth remembering~!

First, the effects on the skin vary depending on the type of indoor lighting. Commonly used fluorescent lights, LED lights, and incandescent bulbs each have their own spectrum and color temperature. In particular, LED lights emit blue light, which can directly affect the skin. According to research, blue light can affect melanin production in the skin and may cause pigmentation, which can especially worsen skin concerns such as melasma and freckles. Therefore, when using LED lights indoors, it is important to take appropriate measures to protect the skin.

Second, the brightness and color temperature of lighting also affect the skin. Bright lighting can make skin imperfections stand out more, which can also have a negative psychological effect. On the other hand, lighting with a warm color temperature can make the skin look softer and healthier. In particular, people with sensitive skin should adjust the color temperature and brightness of the lighting so that it does not place extra stress on the skin.

Third, indoor lighting can also affect the skin’s moisture retention. Excessive brightness or improper lighting can cause moisture in the skin to evaporate, which can lead to dry skin and wrinkle formation. When the skin becomes dry, wrinkles naturally become deeper and the skin’s elasticity decreases. Therefore, it is very important for skin health to adjust the indoor lighting environment and maintain appropriate humidity. Using a humidifier or placing indoor plants to help maintain natural humidity is also a good idea.

Fourth, indoor lighting can also affect our daily patterns. In particular, if you are active under overly bright lights at night, sleep quality may decline. Lack of sleep reduces the time needed for skin recovery, which can accelerate skin aging. So improving your sleep environment by adjusting indoor lighting is one way to maintain skin health. In the evening, try to create a cozy atmosphere by using only warm-toned lighting as much as possible, and from one hour before sleep, dim the lights further. You’ll fall asleep much more easily. ^^

Indoor lighting is also one factor that affects skin pigmentation and wrinkle formation.

Together with sunscreen, improving the type of indoor lighting and the environment can help you maintain beautiful, healthy skin.
