When it comes to Silk, Faux Mink (usually just referred to as mink) and Synthetic lashes they're all just different names for the same thing. These lashes are all man made, using synthetic fibres.
While the materials are the same, the quality and finish of these lashes can vary. Some may have a glossy sheen to them, while others may have a more matte finish. The glossier lashes will often be branded as 'silks' while lashes with a matte finish tend to be branded as 'minks'. There's currently a lot of inconsistency in the industry however, so this isn't always the case. All that really matters is that you like the look and feel of the lashes you choose. Here at My Lash Store we brand our range as 'silks' due to the finish being on the glossier side.
Real Mink lashes refer to hairs that are actually farmed from live minks. While many people will claim that the Minks aren't harmed during this process, there's a lot of debate over whether or not this is true. For this reason My Lash Store chooses not to stock Real Mink lashes.
