Abstract
The science of formulation involving cosmetic ingredients has always been a challenge
since the release of active components greatly depends upon the carrier system involved
and the selectivity of skin barrier. The principle obstacle of the skin resides in
the epidermis and it’s hard for many active components to cross it. The formulation
related factors like size of particles, viscosity and lipophilicity of the components
also play an important role in permeation of the dermal composition. Though widely
used; conventional creams and gels still struggle in terms of success. This work focuses
on nano based formulation strategies for successful delivery of cosmetic agents. Novel
strategies like nanoemulsion, nanogels, liposomes, aquasomes, niosomes, dendrimers
and fullerenes have paved way for successful delivery of dermal formulations to desire
depths in the skin.
