Detailed answer

Serums are lightweight and highly-concentrated formulations that can address various skincare concerns. They come in different types such as hydrating, anti-aging, brightening, and clarifying serums. Due to their lightweight texture, serums are suitable for all skin types, including oily, dry, combination, and sensitive skin. However, it is important to choose a serum that is specifically formulated for your particular skin concern. If you have sensitive skin, it is advisable to patch test new serums and choose ones that are fragrance-free and hypoallergenic. Additionally, individuals with oily skin can opt for oil-free or water-based serums to prevent any greasiness. To ensure optimal results, it is recommended to incorporate serums into your skincare routine after cleansing and toning, and before moisturizing.
