I have not had any issues with this product. I have been using it for 3 months now, and my skin likes it!
Once a day, I dispense 1.5-2 pumps, and VERY GENTLY massage it on my face. I try to avoid rubbing my fingers to my skin; instead, I let the bubbles do the work.
It has little to no scent, but be careful not to let it get into your mouth it's quite salty. Although that may sound off-putting, do not let that discourage you. Salt is a great exfoliant, and because it never dissolves completely in water, its tiny particles can gently remove dirt from your face.
