Warning: it is strongly scented like alcohol and stings every now and then. The tingle is bearable, however, and in my opinion a sign that it's working. DO NOT apply it over broken skin or blemishes that have been victim of your fingertips though - it will hurt!
I wouldn't say it has wowed me like I hoped (I had high expectations), but it is good and effective! It seems to work much better on more mature pimples...aka. ugly white heads...but I would rather it miraculously zap away painful spots that appear under the skin and linger for way too long. Unfortunately it doesn't make them disappear overnight, but it does seem to shrink them. I've also noticed less scarring and hyper pigmentation after I incorporated this treatment into my skincare routine.
It costs $20 CAD, which is neither cheap nor overly expensive, but a little goes a long way and this bottle is going to last a while.
So, although it's not exactly gold...I am a fan and I am happy I gave this product a chance.
