What product should be used to dissolve oils and close pores on oily skin?

1. Toner

2. Moisturizer

3. Exfoliator

4. Serum

The correct answer is: Toner

Using a toner is effective for dissolving excess oils on the skin and helping to close pores, especially on oily skin. Toners often contain ingredients such as witch hazel, astringents, and various acids that can reduce oiliness and tighten the skin. The application of toner after cleansing helps to remove any remaining impurities and balance the skin's pH, contributing to a fresher and clearer complexion. In contrast, moisturizing products are designed to hydrate and nourish the skin without necessarily addressing oiliness or pore size. Exfoliators focus on sloughing off dead skin cells to prevent clogged pores but do not specifically target refining pore appearance or directly addressing oil levels. Serums, while beneficial for various skin concerns, typically provide concentrated active ingredients and may not have a direct impact on oil reduction and pore tightening like toners do.
