It is effective.. but it usually takes 4-5 patches to dry up.

so far this product is good . repurchase ? absolutely yes !

So great to have this set at home in case of pimple emergency. I heped me twice to avoid from ugly pimple. I put it on night and in the morning it is almost gone. Great! 

- very effective to treat coming spots 

- does not dry your skin underneath 

- prevent from having scars or any hyper pigmentations due to the spot

All I am going to say is they work amazingly everyone needs them they are a holy grail product just buy them and buy lots for the rest of your life
