8 Easy-to-do Steps to better skin:
To begin, you should wash your hands thoroughly and also wash and pat dry any skin areas that you are going to use.
To prevent stinging, next apply to the skin being treated, a numbing antiseptic gel, keeping it away from your eyes.
Using a paper towel, wipe off any excess gel.
Make sure the roller has been sterilized in an alcohol bath for 3 minutes.
Using care slowly roll the roller across your skin 4 times back and forth and right and left diagonally over every area of skin being treated.
Do not use on eyelids or lips.
No blood should be visible if light pressure is used, although you may see some temporary reddening.
Sunblock can actually prevent reddening.
Dip a clean face cloth into a bowl of iced water and dab on the areas treated (This will help reduce the pores).
Pat dry with a clean towel.
After use, liberally apply an antibacterial cream and moisturizer to the areas treated.
Moisturizers containing Vitamin C and E are best. With proper use you will begin to see noticeable results in as little as 4-6 weeks and what's more, you will have achieved these results without expensive and potentially dangerous surgery and/or injections
