Is this suitable for sensitive skin, or if I already use retinol, acids or scrubs on my body?

The source explicitly advises caution here. It says it is wise to watch how your skin responds, especially if it is very sensitive or if you already use exfoliating acids, retinoids or scrubs on the body. Combining several retinol-based or exfoliating products can over-strip the skin and increase the risk of irritation, so if you already use those products, consider alternating days or reducing the frequency of each.

Avoid using the gel on broken or irritated skin. If dryness appears after use, the source recommends combining it with a richer moisturizer after showering. For most people, starting with a few uses per week and observing the skin's response is a practical approach; if the skin tolerates it well, you can increase frequency. If you have a chronic skin condition, are pregnant or breastfeeding, or are on medication, consult a specialist before use.
