Final answer:
Products designed to remove excess dead cells from the skin surface are called exfoliants, which help in skin renewal and clarity. Cleansers, toners, and moisturizers are used for different purposes like cleaning, balancing pH levels, and hydrating the skin, respectively.
Step-by-step explanation:
Products that help remove excess dead cells from the skin surface are called exfoliants. The removal of excess dead skin cells from the surface helps in skin renewal and unclogging pores, making the skin smoother and clearer. On the other hand, cleansers are used to remove dirt, oil, makeup, and other types of pollutants from the skin, helping to prevent acne and skin irritation.
Toners are used after cleansers to remove any remaining makeup or cleanser residue, to balance the pH levels of the skin, and to prepare the skin for moisturizers or other skin treatments. Lastly, moisturizers are applied to hydrate the skin by modifying the rate of water loss, containing active ingredients such as occlusives and humectants that help to trap moisture in the skin or draw moisture from the environment into the skin's surface.
