Due to a greater capacity to synthesize melanin, a natural pigment for protecting the skin from UV rays, black skin has a better adaptation to the sun compared to Caucasian skin. However, the tolerance of black skin is not without limits. Indeed, this natural protection is most of the time insufficient, the risk of burns ("sunburns") and other undesirable effects (spots) is not excluded. It is therefore important to understand the challenges of sun protection adapted to black, matte and mixed skin.
Let's see in detail the reasons and solutions provided by the IN'OYA Laboratory ...
The sun's rays: different wavelengths for different effects
The sun's rays that arrive at the surface of the earth break down into 3 different types according to their wavelength:
- Infrared (IR), giving the feeling of heat.
- Visible light, allowing to distinguish the different colors of the light spectrum.
- Ultraviolet, themselves divided into 2 types: UVA and UVB. Their action on the body is both beneficial but also has disadvantages. Indeed, UVB is essential for the synthesis of vitamin D, which allows the mineralization of bones. UVA and UVB are also used in the treatment of certain dermatoses, such as psoriasis. However, UV rays are also responsible for burns (erythema), accelerated skin aging (helioderma) and even skin cancers (carcinomas and melanomas).
Melanin, an insufficient natural protection
Melanin, and more specifically eumelanin, the pigment responsible for the brown color of integuments, is essential to protect against the effects of the sun. As a result, black and matte skin is naturally better protected against UV radiation. On the other side of the coin, vitamin D deficiencies are more common.

During intense sun exposure, this natural protection is insufficient; the risk of the appearance of brown spots is accentuated. Also, the sun also aggravates acne and darkens scars. Other dermatoses, such as melasma, can occur because of UV radiation. Although in winter the feeling of heat decreases, sunny days deserve the same attention as in summer. This rigor is all the more important when an anti-spot or acne treatment is undertaken because the skin is more vulnerable to radiation. |
In'OYA Laboratory's solutions to protect your black skin without white traces

My SUN'OYA® SPF 50 sun fluid is perfectly suited for black and matte skin since it is easy to spread and guarantees optimal protection without white marks. On the other hand, an innovation incorporating a patented active ingredient vitamin D-Like has also been added to combat vitamin D deficiencies. Finally, the presence of vitamin E, a powerful antioxidant, helps fight against harmful free radicals formed during sun exposure. The composition of My Solar Fluid SPF 50 SUN'OYA® has been studied with the greatest attention, excluding the presence of nanoparticles, the use of which is now questioned by scientists. Helianthus annuus oil allows light hydration with a matte finish thanks to the incorporation of tapioca powder. |
