Can I use this if I already use other exfoliating products like AHAs/BHAs or retinol?

Proceed with caution and pay close attention to how your skin reacts. This lotion contains citric acid, which helps refine the skin's surface. If you are already using other exfoliating products such as alpha-hydroxy acids (AHAs like glycolic acid), beta-hydroxy acids (BHAs like salicylic acid), or retinoids, layering them could increase the risk of irritation, redness, or dryness.

A good approach is to introduce this product gradually. You could start by using it once a day, perhaps only in the morning, while continuing your other actives in your evening routine. Watch for signs of sensitivity, such as stinging, peeling, or significant redness. If any irritation appears, you should stop use. It is often recommended to consult with a dermatologist or skincare specialist before combining multiple products with active ingredients, especially if you have sensitive, reactive, or compromised skin.
