Hi Sam and a big welcome to the forum. Congratulations on taking the initiative to start looking after your skin. I am no skin expert but I do know a lot about different products etc. Starting with what you have purchased I would start:
Cleansing with you cleanser twice per day, once in the morning and once before bed at night. Cleansing really is the most important part of any skin care regime as it gets rid of all the toxins and dirts etc that build up on the skin and cause breakouts etc.
I would use the sample exfoliant scrub you got once to twice a week to start off with. You need only use a small amount and evenly distribute it on your forehead, nose, chin and cheeks. Massage in gently and in small circular motions (remember to massage gently as you don’t want to be too harsh on your skin).
I would suggest moisturising only when and where you need it. Did you get a skin consultation with your purchase. Do you know your skin type?
You also might like to get an eye cream to use on the delicate skin under your eyes. There are many different sorts avaialble and I’m sure Allison or Luisa Brown could recommend one for you. I am currently using Dermadoctor Wrinkle Revenge eye cream and it is amazing. However I don’t want to give you a heart attack by telling you the price of it so I will leave the suggestions to the professionals!
Good Luck with your skin care!!
