Pre-cleanse, cleanse and tone the skin. Introduce Retinol by adding one drop to your recommended Environ vitamin A moisturizer every evening. Gradually increase the amount of Retinol while ensuring that your skin remains comfortable. Use 2-4 bottles before progressing to the next step of Retinol. Alternatively, apply Retinol to the entire face area or to the areas you would like to target before moisturizing with your recommended moisturizer. These steps can eventually be followed morning and evening.
