Why this vitamin A powerhouse remains a cult favorite—and how to choose the right level for you.
The AVST moisturisers by Environ are some of our most requested skincare staples—and with good reason. This industry-favorite range is a smart, strategic way to introduce vitamin A into your skincare regimen. But with five levels to choose from, it’s easy to feel unsure about where to start and when to level up.
Here’s our definitive guide to navigating the Environ Skin Essentia AVST range—so your skin gets the most out of this results-driven line.
What is AVST?
AVST stands for Advanced Vitamin Skin Therapy, and the range is endorsed by the Swiss Vitamin Institute—a gold standard for potency and efficacy. At its core, AVST delivers increasing concentrations of vitamin A, which is one of the most critical nutrients for skin health.
Vitamin A improves cellular turnover, visibly reduces the appearance of lines and wrinkles, and promotes a more even skin tone. As Dr. Des Fernandes, Environ’s founder, often says: “Your skin needs vitamin A like your body needs oxygen.” It’s not optional—it’s essential.
Why the Numbers?
The AVST system includes five levels (AVST 1 through AVST 5), each with a progressively higher concentration of vitamin A and other active ingredients. This step-up system allows your skin to gradually build tolerance, helping to avoid common side effects like dryness or flaking.
Starting at a higher level might sound tempting—but trust the process. It’s designed for long-term skin health, not short-term gains.
Which AVST Level is Right for Me?
Always begin with AVST 1. Even if you’ve used other forms of vitamin A before, Environ’s delivery system and potency require a measured approach.
Once your skin has comfortably adjusted to a level—usually after finishing one or two bottles without sensitivity—you may be ready to move up. AVST 3 is well-tolerated by most skin types, while levels 4 and 5 are more potent and best introduced with guidance.
Pro tip: To transition smoothly, you can blend a small amount of your current level with the next one up. This helps ease your skin into the next stage without overwhelming it.
