I'm on my 5th bottle and this formulation never seems to disappoint.
If you have oily to combination skin trust me you will need to get this. I usually break out before my period but this keeps things at Bay and keeps my skin, clear, bright and smooth. Do not use it under your makeup I find it works best if I use this serum before I go to bed. As the AHA and BHA gently exfoliates my skin while I'm sleeping. This is probably the main reason why I always get a nice healthy glow whenever I wake up after using this serum.
