Exfoliation scrapes off the dead skin cells from the surface and reveals the fresh new cells from underneath. It is important that you exfoliate your neck and décolleté areas on a regular basis in order to keep the skin healthy and radiant. Use a gently exfoliating skin care product tthat gently strip off the dead cells without removing the natural moisture of the skin. However, avoid using cleansers and scrubs that contain harsh particles. This is because the skin on these areas extremely thin and fragile and can be easily damaged by harsh ingredients.

Another important step that is often overlooked is moisturization. Often women use moisturizers on their face but forget to extend it to the neck and décolleté areas. Body moisturization is an essential step towards healthy skin care. Therefore use a hydrating cream and slather it liberally over your neck and décolleté. The best time to moisturize your skin at night is immediately after you get out of the shower. This is because the moisturizing ingredients are able to penetrate better and the water locks the moisture within the skin surface.
 

To enhance dermal tissue support, Guerlain explains the appropriate technique:

First, take a little cream and warm it in the palms of your hands.

Place your open hands at the base of the neck, moving upwards until your fingers touch the nape of the neck. Apply light pressure using your fingertips.

To increase dermal tissue tone, place your hands flat against your chest, facing each other, and draw them outward while pressing firmly with your fingertips. 

To oxygenate the skin, place an open hand around your throat and draw it downward to your décolleté, alternating one hand after the other.

Repeat each step 5 times.

Guerlain suggests her Orchidée Impériale Neck and Décolleté Cream, a concentrate of active ingredients to preserve the radiance of the neck and décolleté. A combination of licorice and algae extracts reinforces Imperial Orchid Molecular Extract's powers to regulate pigmentation for brightening action. Extracts of Geranium Robertianum inhibit the enzyme responsible for the deterioration of collagen structures I and IV, which are the guarantors of the architecture and tone of the skin's underlying structure and support. Its re-densifying action is reinforced by a double anti-slackening effect: A soy protein extract stimulates the myofibroblasts, cells that support skin tissue networks, and a plant-based film helps to tighten the skin. After treatment, the neck and décolleté appear immediately smoothed, as if lifted. Spots are diminished; the décolleté recovers a satiny radiance. With continued use, the skin recovers its strength and tone; it appears denser, stronger and firmer.
