Skin hydration, barrier function, and the gradual introduction of vitamin A.

AVST Moisturizer 1 is the starting point in the Skin EssentiA Vitamin STEP-UP System. It contains a low concentration of vitamin A, alongside antioxidants and vitamin C, to help the skin begin normalizing moisture levels and supporting overall skin function. This measured approach allows the skin to adapt comfortably while laying the foundation for long-term skin health.

Used after cleansing and toning, as your daily moisturizer. Suitable for morning and evening use.

Ideal for those new to vitamin A or returning after a break. Often recommended when building a consistent, skin-first routine focused on long-term support rather than immediate change.

After cleansing and toning, apply to the face and neck and massage gently into the skin. Use morning and evening.

Use a minimum of 2–3 bottles before advancing to the next step.

This moisturizer is designed to be used consistently before progressing within the Vitamin STEP-UP System. Most skin benefits from using a minimum of two to three bottles before moving to the next level.
