I am new to phermo. so I don’t know what to expect per say…I just ordered my first phermo. spray (Instant Shine) and I rec. a free bottle of MX423. I can say this…MX423 smells so damn good! LOL…LOL. I have been using it with Instant Shine yet I don’t know what to expect from either per say. I will say that when I used the Instant Shine, I seemed to be more confident.
