Detailed answer

It is recommended to exfoliate before using a serum. Exfoliating helps remove dead skin cells and impurities from the surface of the skin, allowing the serum to penetrate more effectively. By exfoliating first, you create a clean and smooth canvas for the serum to work its magic. However, it's important to choose the right type of exfoliation method suitable for your skin type and be gentle to avoid over-exfoliation. Additionally, always follow the instructions provided by the serum manufacturer for the best results.
