Ethosomes of Phenylethyl Resorcinol as Vesicular Delivery System for Skin Lightening Applications

Figure 5

The effects of ethosomes containing PR on melanin production and tyrosinase activity in B16 melanoma cells. B16 melanoma cells were treated indicating formulations (each formulation containing 5 μM PR). Relative melanin contents and tyrosinase inhibition activity were measured at 24 h after treatment. Each value represents the mean ± SD (). , compared with the control (a). The visual examination of melanin content (b).
