In much the same way that a painter uses primer to smooth a surface so paint better adheres to it, facial primers even out the surface of the skin, providing a smoother canvas for a lasting make-up finish — or a natural, no make-up look. The last step in a skin care regimen, a primer also acts as a protective barrier and helps seal in the benefits of skin care products.While the majority of cosmetic makeup primers focus on improving the appearance and wear of make-up, Dermalogica Primers bridge the divide between skin care and color cosmetics by optimising skin health benefits to improve the look and feel of the skin.HydraBlur Primer is the ideal multi-tasking primer for all skin conditions, particularly dry or dehydrated skin. A lightweight, non-greasy formula, it powerfully hydrates and transforms skin into an even surface with its neutral tint and dramatic "blurring" effect.SkinPerfect Primer SPF30 is a make-up primer, sunscreen and treatment for skin ageing in one. Designed to control and prevent skin-aging triggers, it helps fill fine lines and improve skin firmness while balancing skin tone and enhancing luminosity.Formulated without comedogenic waxes or common skin irritants, Dermalogica Primers can be worn alone or underneath make-up for a flawless finish.
