The Environ range works as a step up process so everyone, unless you are very oily,/acne prone or very sensitive will start on AVST 1 as your day and night moisturiser, with SPF over your AVST during the daytime. When you have used up 2 bottles of AVST 1 you will then move up to AVST2 and so on. By introducing selected products within the range there are 12 steps and as you work your way up through these steps the level of Vitamins A, C & E increases with each level so you are always progressing with your skincare and not just staying at the same level. The range also includes a full range of items to suit each skin concern and need.
We would always recommend consulting your Environ Therapist before considering moving up to the next level.
