Detailed answer

Serums are highly concentrated formulas that contain active ingredients targeted to address specific skin concerns. For acne, serums containing ingredients like salicylic acid or tea tree oil can help unclog pores and reduce inflammation. Anti-aging serums often contain ingredients like retinol or hyaluronic acid to promote collagen production and improve skin elasticity. Serums for hyperpigmentation may include ingredients like vitamin C or niacinamide to brighten and even out skin tone. It's important to choose serums with appropriate ingredients and use them consistently as part of a skincare routine to see desired results. Remember to read product labels, patch test new products, and consult with a skincare professional if needed.
