What is the definition of Serums? 🙋 🔍
A serum is a liquid or suspension containing a concentrated amount of an active ingredient, such as a drug or a plant extract. It is typically used in the treatment of skin conditions, such as eczema, psoriasis, and acne, to provide localized relief from inflammation and itching. Serums are often applied topically to the skin and can be diluted with water for easier application. They are generally sterile and safe for use by healthcare professionals.
