SLIK was designed to be used for chafing caused by friction think the kind between thighs, underarms, under sports bras, etc. Whilst its buddy SLATHER was designed to protect skin from tearing and chafing caused by bike seats and the rubbing between your toes, etc.
Many of our Skin Strong Squad use SLATHER and SLIK interchangeably, and many customers use them together in problem areas such as under sports bras. We recommend a spray of SLIK followed by SLATHER where exceptional chafe protection is needed!
