If on the third day of using Benzagel 5, my skin has become dry, is this normal?

Yes, it is normal for Benzagel 5 to dry out your skin if you apply it all over. It is recommended to only apply it to the areas where you have acne or are prone to getting it. Additionally, it is important to use a moisturizer specifically designed for acne-prone skin to keep your skin hydrated. Make sure to apply it in the morning and evening for best results.
