Sunbathing has multiple benefits: it improves your mood, promotes the synthesis of vitamin D, helps enhance your immune system… But excess sunbathing and not using sunscreen can be dangerous. The most obvious and immediate consequence of prolonged and unprotected sun exposure is skin redness, which can lead to sunburns, even if you have used sunscreen. According to the latest studies published in the British Journal of Dermatology, we don’t reapply sunscreen correctly, apply a suitable amount or reapply it as frequently as we should.
Regardless of your skin type, overexposure to ultraviolet (UV) radiation is directly related to premature skin ageing, therefore protecting your skin only externally is not enough. A very recommendable option is to include in your diet products that help protect your skin from within, such as REPASKIN Helioses, an innovative nutraceutical based onPolypodium Leucotomos chitosomes.
Polypodium Leucotomos, also known as calaguala, is a tropical fern from the rainforests in Central America. It originally grew in water, but during its evolution over thousands of years it adapted to life on land, developing auto-defence mechanisms that allowed it to protect itself from the sun and repair its damage. According to numerous studies, oral intake of Polypodium Leucotomos can effectively counteract and repair most negative effects of UV radiation on the skin, including photo-ageing, thanks to its powerful antioxidant action*.
However, Sesderma’s R&D team discovered that the properties of this tropical fern in its natural form are not enough to achieve repair, and it is necessary to apply nanotechnology to encapsulate Polypodium Leucotomos.
Chitosomes are a new encapsulation system developed by Sesderma using their know-how and wide experience in the field of nanotechnology, combining the properties of liposomes and chitosan. Liposomes are known for being excellent carriers of orally-administered molecules. Sesderma uses them in most of their products, since they extend the action time of the active ingredients and maintain their effectiveness against degradation. On the other hand, chitosan is a biopolymer with many properties; through encapsulation, it helps improve the bioavailability of Polypodium Leucotomos compared to its free form,minimising damage caused by sun exposure on the skin**.
The innovative formulation of REPASKIN Helioses helps enhance the effectiveness of its active ingredients thanks to nanotechnology in order to provide greater benefits for the organism.
