Detailed answer

Serums are lightweight and typically have a water or gel-like consistency, which means they won't contribute to oiliness. Unlike moisturizers or creams, serums are designed to penetrate deeper into the skin and deliver active ingredients, such as antioxidants, vitamins, or hydrating agents, without leaving a greasy residue. In fact, serums can actually help balance oil production by providing the skin with the necessary hydration it needs, reducing the likelihood of excessive oil production. However, it is important to choose a serum that is appropriate for your skin type and concerns. If you have oily skin, opt for oil-free or mattifying serums, and if you are unsure, consult with a skincare professional for personalized recommendations.
