Formulation, characterization and invitro permeation/penetration of a-Arbutin creams and hydrogel / Nurul Fatin Fakhira Mohd Padli
a-Arbutin is a skin whitening active which is highly hydrophilic and difficult to permeate into hydrophobic skin barrier. Nowadays, cosmetic consumers are mainly focused on the multi-sensory experience of a cosmetic product. However, a cosmetic product with good sensory feeling upon application is n...
