Ladies, please take my testimonial seriously because I speak the truth here. I am 43 years young. I started to seriously take care of my skin at the age of 35 after my son was born. I started using Dr. Perricone's products which I must say did wonders but as we age we lose elasticity and start deflating in the jowel area. I spent an insane amount of money on a cream that was supposed to address that problem from his line and it did absolutely NOTHING. I was very dissapointed and started looking in to non surgical fillers even botox to fix the problems. Then I started browsing this line and said I will give it one last try. This product is incredible, my jowels tightend within days, my 11 line is just about gone!! My close friends thought I went ahead with botox and fillers that is how great this serum is. Worth every penny!! Believe it!!
