Various studies have proven red light therapy’s effectiveness against common skin concerns such as hyperpigmentation and dark spots - and while the treatment may seem straightforward, there are a few factors that must be taken into account to ensure its peak efficiency. One of these involves the wavelength at hand, which affects how deeply the light penetrates the skin. Longer wavelengths penetrate the skin deeper than shorter ones.
When targeting hyperpigmentation and dark spots, in particular, two of the most commonly recommended wavelengths are 630 nm and 810 nm. For those new to red light therapy, choosing between the two might be overwhelming, but don’t worry. This guide from our team at ROJO Light Therapy EU will help clarify the differences between the two to help you make an informed choice.
This shorter wavelength primarily affects the epidermis and upper dermis, penetrating approximately 2mm deep. This makes it ideal for addressing surface-level concerns such as pigmentation irregularities, redness, and uneven tone. It does so through a set of mechanisms including the following:
More often than not, overactive melanocytes, the cells responsible for melanin production, are the culprits behind hyperpigmentation. Studies have found that red light therapy in the 630nm wavelength can help mitigate their effects. Given that red light does not promote melanogenesis, it shows great potential in modulating melanocyte activity, reducing excessive melanin production, and redistributing pigment evenly across the skin.
Inflammation can make pigmentation issues worse - but with red light therapy, this can be avoided. The treatment has been observed to reduce inflammation by modulating inflammatory pathways which calms the skin. This creates an optimal environment for healing and lessening the risk of further pigmentation.
Increased collagen and elastin production is necessary to improve skin texture which can help make dark spots less visible over time. Experts generally recommend 630 nm - 680 nm of red light therapy to stimulate the necessary cellular processes to enhance collagen and elastin production.
This longer wavelength reaches deeper layers of the skin, penetrating up to 5mm. It’s ideal for deeper tissue concerns, improving microcirculation, and reducing oxidative stress. Here’s how it can aid in reducing hyperpigmentation and dark spots.
Near-infrared light at 810nm directly stimulates cytochrome c oxidase, a key enzyme in the mitochondrial respiratory chain. This powers the maximum production of adenosine triphosphate (ATP), which bankrolls the cells’ repair and rejuvenation abilities. This helps fix the damage to the skin barrier causing hyperpigmentation and dark spots.
Near-infrared light at 810 nm reduces the buildup of reactive oxygen species (ROS) and inflammation. With this, the skin is better able to maintain a balanced melanin production process and heal from damage.
Studies have shown that red light therapy can enhance microcirculation through the release of nitric oxide (NO), which encourages vasodilation - effectively increasing the density of blood flow across affected blood vessels. Through this, the skin cells get the nutrients and oxygen they need, allowing accelerated skin turnover. While it is a gradual process, this slowly but surely evens out the skin tone.
Selecting the best wavelength ultimately depends on your specific skin concerns and goals. Consider the following:
By understanding the unique 630nm and 810nm red light therapy benefits, you can target your concerns with precision and confidence. However, effectively treating concerns such as hyperpigmentation and dark spots take time and most importantly, consistency. Also, having a quality device is essential.
