my sister is a cosmetic surgen and she put me threw 5 lots of treatment at her clinic over 5 months. i have noticed that there has been a massive inprovemnt. the results are best achieved with after treatment care. no face scrub or anythig abrassive. only a light moistuiser and some sun screen for a week after. using a face scrub will cause large sun spots 2-6 days after treatment and they can be permenent. was worth all the pain!
