Provided are cosmetic preparations for topical application containing nanocrystals of cosmetic actives leading to an increased bioactivity of the molecules in the skin and methods of making the cosmetic preparations. The nanocrystals can be added to any cosmetic topical formulation, e. g. creams, lotions and liposomal dispersions. The drug nanocrystals are produced by a combination process of low energy pearl milling followed by a high energy high-pressure homogenization leading to nanocrystal suspensions (nanosuspensions) of improved physical stability.
