MICROSPHERES
Microspheres, typically defined as spherical
microparticles between 1 micron and 1000
microns (1 mm) in diameter, have been widely
used in personal care and the cosmetics
industry over the past decade. In skin care
lotions and creams, microspheres can help
deliver a soft and smooth feel, excellent lubricity
and soft focus effects that reduce the
appearance of fine lines and wrinkles.
Microspheres have numerous advantages in the
personal care and cosmetics industry. Due to
their unique geometry and the smallest surface
area to volume ratio of any shape, microspheres
offer beneficial properties such as ball bearing
effect for superior texture, light scattering or
“optical blurring” for minimising lines and
wrinkles, gentle but effective exfoliation, as well
as the ability to house colorants and active
ingredients. The use of microspheres in the
personal care and cosmetics industry is growing
as microspheres are getting incorporated into
an increasing number of anti ageing creams
(Sharma and Sharma, 2012).
CR1 Moisturiser is an example of microsphere
containing anti-ageing formulation. It is a deeply
hydrating cream with anti-ageing collagen
tripeptide microspheres which adheres to the
skin upon application stimulating collagen
synthesis thus reducing signs of wrinkles.
