The photoaging processes, which are caused by UV radiation, are the main source for skin damages and its early and accelerated aging processes. The UVA rays constitute the main cause for early aging of the skin and to the appearance of dyspigmentation spots and the formation of wrinkles. They penetrate the dermal layer, where they damage the DNA in the skin-cells, and createpro-inflammatory components, which lead to the destruction of the collagen and elastin proteins. The UVB rays are absorbed by the epidermis, and they are the ones that cause sunburns.
Sunscreens are the most important and proven element in the protection of the skin from these damages. The evidence for their effectiveness originates in clinical studies, which point to their effectiveness both in protecting the skin from premature aging and in the prevention of skin cancer. However, in order to gain an effective impact, it is necessary to combine both UVA and UVB protection. At HL laboratories, the area of skin protection is at the center of research and development.
The unique line of sunscreens that has been developed by the company provides the skin with dual protection against the sun’s dangerous UVA and UVB rays, which is based on particularly high sun protection factors (SPF), and on a nano-technology based sunblock that operates to block the sun’s rays in a physical process.
