Question: 1 / 400

What are serums primarily used for in skincare?

Concentrated ingredients used for specific corrective treatments

Serums are primarily used in skincare for their concentrated ingredients that target specific skin concerns and provide corrective treatments. They are formulated with high concentrations of active ingredients like vitamins, antioxidants, and other beneficial compounds to address issues such as aging, acne, hyperpigmentation, and hydration. Serums are lightweight and easily absorbed, making them ideal for delivering potent ingredients deep into the skin for effective results. This is why option A, "Concentrated ingredients used for specific corrective treatments," is the correct answer. Option B, which mentions hydrating and balancing the oil-water moisture content, is more in line with the functions of moisturizers. Option C, protecting the barrier layer of the skin, is typically associated with barrier creams and not serums. Option D, promoting physiological relaxation, is not a primary function of serums in skincare.
