Environ Skin EssentiA AVST 4 Moisturiser is the fourth level in Environ’s progressive Vitamin STEP-UP SYSTEM™ and is designed for experienced Environ users whose skin has already adjusted to the previous AVST levels.
This advanced 50ml facial moisturiser combines Vitamin A as Retinyl Acetate with Vitamin C, Vitamin E, beta-carotene, antioxidants, botanical extracts and Matrixyl® 3000 peptides.
Used morning and evening, AVST 4 helps support the skin’s natural moisture levels while improving the appearance of fine lines, uneven-looking skin tone and texture. Skin is left looking smoother, more radiant and healthier.
AVST 4 is not normally the starting point for new Environ users. If you are unsure which AVST level is right for your skin, our skincare team can help you choose the appropriate step.

Who It Is For
Who It Is For
Environ AVST 4 is best suited to existing Environ users who have progressed through the earlier Skin EssentiA AVST moisturisers and are ready for the fourth step of the Vitamin STEP-UP SYSTEM™.
It may be particularly suitable if you are looking to improve the appearance of:
- Fine lines and visible signs of ageing
- Uneven-looking skin tone
- Rough or uneven skin texture
- Dullness
- Skin that would benefit from greater vitamin A exposure
- Loss of moisture and a less radiant-looking complexion
How To Use
How To Use
- Prep: Pre-cleanse, cleanse, and tone with your preferred Environ products.
- Apply: Massage AVST 4 into the face and neck morning and evening, including the delicate eye area.
- Protect: Always follow with an Environ SPF daily, as high-level Vitamin A requires consistent sun protection.
- Duration: Use AVST 4 for 6–12 months before considering a progression to the final step, AVST Moisturiser 5.

I have been using the AVST series in steps since 2016 and have always purchased from Chelleon. This product has nourished my complexion and supported my skin while transitioning through my late 30s into my 40s. It has helped maintain the health of my skin and minimised aging.
