Sun spots, acne scars, and stubborn dark patches! Skin has its own way of telling stories we’d rather keep private. So, when a trend like red light therapy promises smoother, calmer, glowier skin, the obvious question pops up!
Could this actually backfire and make hyperpigmentation worse? Before you ditch your LED mask or panic over a few freckles, let’s break down the facts, bust the myths, and explore real solutions backed by science!
Everything About Red Light Therapy
Red light therapy uses particular red or near-infrared light wavelengths. It is often referred to as low-level laser (light) therapy (LLLT) or photobiomodulation.
This treatment improves the exposure of the skin to devices. These devices emit low-level lasers or red LED lights, such as masks, panels, or wands. The light enters the body through the epidermis and is absorbed by the mitochondria. They are often referred to as the “power plant” of the cell, where the magic works.
Increased cellular activity from this absorption results in more ATP being produced. It improves cell function, repair, and the development of new cells. Red light therapy employs extremely low heat levels. It also doesn’t burn or expose the skin to dangerous radiation like harmful UV rays do.

Growing Concerns: Side Effects and Hyperpigmentation
There are growing discussions and research surrounding the potential side effects of red light therapy. Even though it is generally considered safe for short-term use, especially when used as directed.
Some individuals have reported mild temporary pain or irritated skin. Although red light therapy does not use cancer-causing UV light, there have been reports of blistering and redness on the skin. Particularly at high levels or with misuse.
There’s an increased sensitivity to visible light, including red light, which may potentially lead to hyperpigmentation. For those with darker skin tones.
Nonetheless, some research also suggests that red light therapy can lessen pre-existing hyperpigmentation. A 2023 study found that the pigmentation of melasma patients decreased following several weeks of treatment at 633 nm. Eye protection is advised to avoid possible eye damage.

Common Uses and Their Effectiveness
Let’s see some common uses of red light therapy and their effectiveness!
Anti-aging and Skin Rejuvenation
RLT is frequently advertised as a way to improve the appearance of skin by minimizing
- Redness
- Acne
- Wrinkles
- Scars
It is believed to function by encouraging the creation of new cells. Not only that, but also the increase in the production of collagen and elastin. Both of which are essential for firm, youthful skin.
According to studies, LED red devices can improve
- Discolouration
- Wrinkles
- Rough skin
- Fine lines
Wound Healing
Red light therapy has shown promise in accelerating the skin’s natural healing process and promoting tissue repair. NASA originally explored RLT for plant growth and to aid astronauts.
Some preliminary studies suggest potential for accelerated skin and tissue healing, although more consistent success is needed.
Acne Treatment
RLT can be effective in managing acne due to its anti-inflammatory properties. It can help reduce redness and swelling. This can also help its ability to target acne-causing bacteria. It may also help treat old acne scars.
Reducing Inflammation
Red light treatment can help soothe redness and reduce swelling because of its well-known anti-inflammatory properties. It is used to treat a variety of ailments outside of the skin because of these properties. For instance: pain and arthritis.
Hair Growth
Red light treatment has been shown in studies to promote follicle growth and enhance blood flow to the scalp. It can result in the regrowth of thinning hair as well as an increase in the thickness and length of existing hair.

Understanding Hyperpigmentation
Hyperpigmentation is a common skin disorder. It occurs when spots of skin produce too much melanin. As a result, it makes them darker than the surrounding areas. These spots or patches may make you feel self-conscious. They can be brown, black, gray, red, or pink.
Types of Hyperpigmentation
Age Spots (Solar Lentigines)
These are flat, brown, tan, or black spots. They often show up on portions of the face and hands that are exposed to the sun. They usually affect elderly folks or people who have been exposed to the sun for a long time. Another name for them is liver spots.
Melasma (Chloasma)
Melasma is often called “the mask of pregnancy.” Melasma (chloasma) is characterized by big, darker areas of skin, usually on the forehead, face, and stomach. It mainly affects people with medium to darker complexion tones and women. Particularly those who are pregnant or taking birth control pills.
Post-inflammatory Hyperpigmentation (PIH)
This kind appears as darkish patches or spots. They appear after a skin injury or after an inflammatory skin disorder like eczema or acne. Sun exposure can exacerbate the appearance of PIH. It can form anywhere on the body.
Causes of Hyperpigmentation
UV Exposure
The body produces more melanin after extended exposure to the sun as a defense mechanism. It results in dark spots like sun spots or age spots. One of the main causes of skin pigmentation is UV exposure.
Inflammation
Areas of the skin may darken as a result of inflammation brought on by diseases, including
- Lupus
- Eczema
- Acne
- Trauma
Those with darker complexion tones are especially prone to this.
Hormonal Changes
Dark patches of skin, like melasma, can be brought on by hormonal changes. Such as those that occur during pregnancy or as a result of taking oral contraceptives. It is well known that when the body is exposed to sunshine, the female sex hormones progesterone and estrogen promote the production of melanin.
Drugs and Medical Conditions
Some medications can cause hyperpigmentation. Such as tricyclic antidepressants and antimalarials. It can occasionally turn areas of skin gray. Hyperpigmentation can also result from more severe medical disorders like
- Hemochromatosis
- Addison’s disease
Chemicals used in topical treatments may also result in hyperpigmentation.
Skin Injury
Dark patches can result from melanocytes being stimulated to create more melanin by skin trauma. Such as cuts, burns, or acne. Additionally, picking at spots and scabs can exacerbate hyperpigmentation.

Skin Types More Prone to Pigmentation Issues
People with all skin types are susceptible to the prevalent skin disorder known as hyperpigmentation. On the other hand, dyschromias like post-inflammatory hyperpigmentation are more common and more severe in those with darker skin tones. Such as Fitzpatrick skin types III to VI. This is because melanin content is naturally higher in darker skin.
Can Red Light Therapy Cause Hyperpigmentation?
Red light therapy, or RLT, is generally regarded as safe and usually helps to lessen hyperpigmentation rather than increase it.
According to scientific research, LED irradiation can dramatically lower
- Tyrosinase expression
- Melanin formation
Especially at wavelengths like 830 nm and 850 nm. Red light therapy can also assist in balancing melanin production. It will help remove dark spots that are already present and lessen the chance of new ones developing.
Although increased hyperpigmentation is not usually linked to red light therapy. Some research indicates that darker skin may be more susceptible to LED-RL. Hyperpigmentation and temporary erythema were noted as moderate side effects at higher fluences.
In particular, it was determined that LED-RL was safe for skin of color up to 320 J/cm² and for non-Hispanic Caucasians up to 480 J/cm².
When Red Light Therapy Might Affect Pigmentation
Let’s see when red light therapy may affect pigmentation!
Inappropriate Use (Wrong Wavelength, Intensity, Overexposure)
Even though red light treatment is usually thought to be safe. Using extremely high light intensities may cause burning and redness on the skin. Your skin may get damaged if you misuse products by using them excessively or by not following instructions.
Use on Sensitive or Inflamed Skin
Red light exposure can exacerbate certain skin diseases, including lupus. This causes people to become more sensitive to light. The anti-inflammatory qualities of red light therapy may help soothe irritated skin if you have reactive or sensitive skin.

Reaction with Topical Products (such as Photosensitizing Agents)
Red light therapy should not be advised if you are taking any medications that make your skin more sensitive to light. For instance, photosensitizing drugs that activate when exposed to light.
Even after treatment, some substances may make you more sensitive to light.
Fitzpatrick Scale Skin Type Considerations
Studies show that people with darker skin tones are more sensitive to visible light. Hyperpigmentation is produced by this increased sensitivity. It can also produce darker spots that are more intense and persistent than those brought on by invisible light, such as sunshine.
Physicians can estimate the risk of skin cancer and choose the best settings for light-based therapies. That too, with the help of the Fitzpatrick skin type classification system.
Blue light may momentarily worsen pigmentation in those with Fitzpatrick III and IV skin types (darker skin types). Although subsequent usage of near-infrared light can help lessen this.
