Dark circle has been the biggest problem for me since I was a baby, it is indeed a natural born family signature as my dad also has horrible dark circles. I did not care until I was a teenage, then friends around me asked me to try using concealer to cover up the horrible natural born “issue”. Concealer is considered to be the driest “coverage” foundation, it has to contain a certain level and amount of “thickness” in order to make sure it can cover up dark skin/color tone. It indeed has an immediate awesome results and cover up dark skin tone around eye area for possibly 3 to 4 hours maximum. Immediately after usage, appearance of obvious lines around eye area was the consequences I had to take and became my long lasting problem.
