Fernblock® for the prevention of skin damage caused by visible light and infrared radiation
The harmful effects of UVA and UVB rays on the skin are well known, but increasing knowledge is emerging regarding the role of visible light and infrared radiation on skin aging, hyperpigmentation and sun allergies. A recent in vitro study has once again shown the protective action of Fernblock® technology developed by Cantabria Labs, and its contribution to reducing collagen loss caused by visible light and infrared radiation.
This article by Alicia Zamorron et al. was published in the scientific journal “International Journal of Molecular Sciences”. The study demonstrates that the use of Fernblock® could prevent skin damage and, in particular, aging caused by exposure to visible light and infrared radiation.
It is known that visible light and infrared radiation increase the expression of Metalloproteinase 1, an enzyme that is responsible for collagen degradation, while infrared light causes a significant decrease in fibrillin and elastin, both important for the biomechanical properties of most tissues and organs. As can be seen from the study, the protective action of Fernblock® against photo-aging is particularly clear.
Tests performed on dermal fibroblasts showed that Fernblock® increases the survival of cells irradiated with visible light and infrared radiation and reduces the activation of agents that are responsible for collagen degradation, thus protecting the components of the extracellular matrix. Fernblock® also increases the expression of fibrillin and elastin to regenerate the elements of the extracellular matrix of the skin and thereby combat aging.
The investigators conclude that the results support the use of Fernblock® as a tool against skin damage caused by exposure to infrared or visible light, as well as being beneficial in preventing photo-aging.
