The concept of circadian rhythms isn’t new, but it has only just started to become talked about and a recent study reveals the importance of the biological clock in the regeneration of skin stem cells. When this system is disrupted it results in premature tissue ageing, as well as a greater predisposition to developing skin tumours. Circadia Skin Care protects the skin from ultra violet damage during the day and regenerates it while you sleep – reducing transepidermal water loss, improving hydration and controlling the skin’s ph levels and temperature.
