Detailed answer

Serums are formulated with high concentrations of active ingredients that can target specific skin concerns. When using serums around the mouth area, it's important to choose ones that are suitable for your skin type and concerns. Avoid serums with irritating ingredients like acids or retinol if you have sensitive skin around the mouth. Patch test the serum on a small area before applying it in larger quantity. Also, make sure to follow the manufacturer's instructions for application and avoid direct contact with the lips. In case of any adverse reactions or redness, discontinue use and consult a skincare professional.
