I cannot tell u enough how this peel changed my life!i have used it many times and my skin has improved amazingly-and transformed my skin after a disfiguring car accident! the formulation is so safe and exact and i have never damaged or burned my skin with it-my skin gets more smooth and glowing every time i use it!i used some of julie;s great retinol peels and latte peels for about 6 months and then graduated to this fantastic peel!i trust this peel as i trust all of ur wonderful products julie!!
