Infrared light is an invisible kind of light that has been gaining popularity in recent years due to its therapeutic benefits. But does infrared light actually produce melanin in the body? In this article, we’ll explore the potential effects of infrared light on melanin production and examine the science behind it.

Does Infrared Light Produce Melanin?


Does Infrared Light Stimulate Melanin Production?

Melanin is a natural pigment that gives color to the skin, eyes, and hair. It is produced by specialized cells in the skin known as melanocytes. The amount of melanin produced by these cells is determined by the individual’s genetic makeup. Exposure to ultraviolet (UV) radiation from the sun or artificial sources can cause melanocytes to produce more melanin, resulting in a darker complexion. Recently, there has been some interest in whether infrared (IR) light can also stimulate melanin production.

Infrared light is part of the electromagnetic spectrum that lies between visible light and radio waves. It has a longer wavelength than visible light, so it has less energy. The amount of energy in IR light is not sufficient to cause changes in the structure of molecules, such as those that make up melanin. Therefore, it is unlikely that IR light can directly stimulate the production of melanin.

However, some studies have suggested that IR light may have an indirect effect on melanin production. For example, IR light may stimulate the production of certain hormones, such as melanocyte-stimulating hormone (MSH), which can then stimulate the melanocytes to produce more melanin. In addition, IR light has been shown to have anti-inflammatory effects, which may reduce the risk of skin damage due to UV radiation. This could lead to a decrease in the production of melanin in response to UV exposure.

Can Infrared Light Help to Tan the Skin?

The ability of IR light to stimulate melanin production is still a subject of debate. Some studies have suggested that IR light can help to tan the skin, while others have not found any significant effects. It is possible that the effects of IR light on melanin production depend on the individual’s skin type and the intensity of the light.

In addition, the use of IR light for tanning is not recommended due to safety concerns. IR light has been shown to increase the risk of skin damage, such as sunburns and wrinkles. Furthermore, the long-term effects of repeated exposure to IR light are not yet known. Therefore, it is best to avoid using IR light for tanning.


In conclusion, there is still some debate about whether IR light can directly stimulate the production of melanin. However, it is possible that IR light may have an indirect effect on melanin production. It is also important to note that the use of IR light for tanning is not recommended due to safety concerns.

Top 6 Frequently Asked Questions

What is Infrared Light?

Infrared light is a type of electromagnetic radiation with a wavelength that is longer than visible light, but shorter than microwave radiation. It is invisible to the human eye and is often used in various applications such as night vision devices and heat lamps.

How Does Infrared Light Affect Melanin?

Infrared light does not directly produce melanin, however, it has been shown to increase the production of melanin in the skin. This is due to the fact that infrared light stimulates the production of melanin-producing cells in the skin, resulting in a darker complexion.

What Are the Benefits of Infrared Light?

Infrared light has a variety of benefits. It can help to reduce pain and inflammation, improve circulation, improve skin tone and texture, and even promote healing. It can also be used to treat conditions such as psoriasis, eczema, and acne.

Are There Any Risks Associated With Infrared Light?

Although infrared light is generally considered to be safe, there are some potential risks associated with its use. The most common risk is overexposure, which can cause sunburn and other skin damage. It is important to use infrared light in moderation and to wear protective clothing and sunscreen when exposed to it.

Does Infrared Light Have Any Other Uses?

In addition to its uses for skin care, infrared light can also be used for a variety of other applications. It is used in medical imaging, thermal imaging, and in the detection of heat loss in buildings. It is also used in night vision devices and as a heat source in saunas and hot tubs.

Is Infrared Light Suitable for All Skin Types?

Infrared light is generally safe for all skin types, however, it is important to consult with a doctor or dermatologist before using it. People with sensitive skin may want to take extra precautions to avoid overexposure, and those with darker skin tones may want to limit their exposure to infrared light.

The MOST POWERFUL Antioxidant Is Melatonin, NOT Glutathione

In conclusion, infrared light does produce melanin in the body and is responsible for the darkening of the skin. It is important to understand the effects of infrared light on the skin to properly protect it from further damage. The skin is the body’s first line of defense against the environment, and its need to be protected from ultraviolet radiation and other hazardous elements. Thus, it is essential to use sunscreen and other protective measures to protect the skin from the damaging effects of infrared light.
