Thought that the SISTAR members got those awesome tans while in Hawaii, shooting their Loving U music video? Guess again.

The secret to their dark skin is out as the members were spotted at a tanning salon.

On July 26, a picture was uploaded on an online community titled, ‘Snapshot of Hyolyn and Soyou at a Tanning Salon.’

The two photos show Hyolyn and Soyou wearing comfortable, but still stylish clothes, as they smiled for the camera in the tanning salon lobby.

Seeing their darkened skin, netizens commented, “SISTAR is so sexy,” “Now I know the secret to their sexiness,” and “I like it because they look healthier.”
