Abstract

Pigmented spots are widely perceived as a sign of skin ageing. These spots occur when the enzyme tyrosinase, which is mainly involved in melanin synthesis, is overproduced because of ageing or overexposure to UV light and pollution. Researchers recently conducted in vitro tests to explore the potential of a new active ingredient extracted from the Lansium domesticum plant to reduce tyrosinase and melanin levels in the skin through a previously unknown epigenetic pathway. In vivo testing then confirmed that this 100-percent natural ingredient decreases the surface area of pigmented spots and reduces the total quantity of melanin. This opens up opportunities for cosmetics manufacturers to meet demand for anti-ageing skincare products that address pigmented spots.


ADDRESSING A COMMON SIGN OF SKIN AGEING

Signs of ageing skin include wrinkles, crow’s feet and pigmented spots. Many consumers use moisturisers to smooth out the first two signs – and a new natural ingredient has now demonstrated efficacy in addressing the third. In vitro and in vivo testing has shown that an extract of the Lansium domesticum plant shrinks and lightens pigment spots on the skin, creating a more homogenous skin tone that is associated with youthful appearance. This 100% natural ingredient with the INCI name Maltodextrin (and) Lansium Domesticum Leaf Extract leverages a new epigenetic mechanism to deal with pigment spots at their root cause rather than just on the surface.

 

Pigmented spots on the face, hands and décolleté area are among the most common visible signs of photoaging. Studies have demonstrated that the formation of these spots is accelerated by exposure to UV light and traffic-related air pollution. An observational study in Japan showed that women from Kagoshima have a significantly higher degree of facial hyperpigmentation than women from Akita, where there is less UV radiatio ...
