Get your skin ready for the summer – take astaxanthin

Sunny and warmer days are approaching, so we have to prepare our skin for sun exposure and shield it appropriately from within.
Different creams, lotions and oils with a protective factor nourish and preserve the skin only superficially. To preserve the skin completely and add a radiant appearance to it, it is essential to nourish the skin from within. Surely you are wondering how to achieve this? The answer lies in astaxanthin – a powerful carotenoid.
The skin’s exposure to UV rays
During spring and summer months, it is natural to spend more time outdoors. Our skin is then more exposed to ultraviolet (UV) radiation. It is important to know that the intensity of UV radiation depends on the time of day and season – it is strongest between 10 and 16 hours during spring and summer months. While being engaged in outdoor sports activities, walking or sunbathing, our skin and subcutaneous tissue are under the direct influence of UV radiation, which speeds up the formation of pigment in the skin, thus affecting tanning of the skin. UV radiation also affects the synthesis of vitamin D in the body.
People who expose their skin to the sun for longer periods of time (farmers, construction workers and similar occupations) are faced with skin problems, because, in most cases, the skin gets rough, it ages more quickly and other diseases may develop, including skin cancer. Research also shows an increasing interrelation between ocular melanoma and exposure to UV radiation1.
Moderate sunbathing in the summer can have beneficial effects on health, but many people spend too much time continuously exposed to the sun’s UV rays, which leads to the formation of free radicals in the body in the process of photooxidation, resulting in tissue damage (membranes, lipids, proteins and DNA cells). The formation of Reactive Oxygen Species (ROS) is considered to be a central mechanism leading to (premature) skin aging2.
How does astaxanthin help to protect and preserve the skin?
Light-skinned people, as well as light-eyed people, are genetically more predisposed to getting sunburns, so their skin can be severely damaged when exposed to the sun. In order to prevent such damage, it is important to use the antioxidant astaxanthin, a carotenoid that allows the skin to adapt more quickly to UV radiation.
Astaxanthin affects skin beauty and glow by protecting it from the harmful UV rays, preventing and reducing hyperpigmentation and enhancing skin elasticity and moisture3.
Although some food contains astaxanthin (algae, salmon, krill, lobster, etc.), we don’t obtain enough of it in our daily diet, so many health authorities recommend using astaxanthin as a dietary supplement, but that is gained from a natural source. Natural astaxanthin, namely, has many times greater antioxidant potential and stability compared to its synthetic form.
