Use a moisturiser that suits the skin type and offers day-long hydration. This will plump up the skin, providing a smooth, even surface for makeup application.
Makeup is easier to apply on a moisturised skin. Moisturiser provides a soothing and protective film on the outer layer of the skin. This helps the skin to remain moist and hydrated by keeping the water content of the skin intact.
Also moisturiser will improve the health of your skin and will protect it from wind, heat and other environmental assault. In short, cleanse, tone and moisturise are the important elements needed for skin care.
