Yes, coconut oil can be used as a cleanser. Its emollient properties help dissolve makeup and grime, but it's best suited for dry skin and should be thoroughly removed to prevent clogged pores.

A primary disadvantage is that coconut oil is comedogenic, meaning it can clog pores and potentially lead to breakouts, especially for those with oily or acne-prone skin. It's also not suitable for all skin types.

Cardiologists often advise limiting coconut oil consumption due to its high saturated fat content, which can raise LDL (bad) cholesterol levels and increase the risk of heart disease. Moderation is key when incorporating it into your diet.

Coconut oil typically doesn't significantly alter the skin's pH. However, using it as the sole cleanser without proper rinsing could leave a residue that might indirectly affect the skin's natural balance. Always follow with a toner if needed.
