Dr Win L. Chiou, a renowned authority in pharmacokinetics, has recently published a commentary in The Scientific Pages of Dermatology questioning some widely accepted concepts and postulating his own new theories in anti-ageing. An expert in dermatology, Dr Chiou believes this may have many important implications and applications in future ageing and anti-ageing research.

It is typically believed that sun exposure contributes to around 80 percent of skin ageing. Dr Chiou believes that exposure to the sun’s ultraviolet radiation has no noticeable effects on the ageing of skin collagen and superficial capillaries. In his research, he found that age spots – commonly assumed to result from photoaging – were frequently found on thighs, forearms and backs in older people that were rarely exposed to sunlight.

Dr Chiou postulates that we need to re-evaluate the general recommendation to wear sunscreen when we go outdoors. He believes this is especially significant because exposure to sunlight has important health benefits such as reducing blood pressure, heart attacks and strokes, and increasing the immune system with vitamin D. He argues these health benefits outweigh the risk of getting skin cancer.

In his commentary, Dr Chiou also theorises that the formation of age spots mainly results from birth defects and later acquired injuries in superficial capillaries that nourish the skin, which is why these disorders are generally first initiated by intrinsic aging. Dr Chiou noted that young children and youths with healthy skin may stay outdoors unprotected daily for months or years without developing age spots or wrinkles.
