Décolleté is a French word that describes the low neckline of a womans dress or top. In the beauty world, it means the area of a womans chest and neck that a low-cut top would expose. The skin in this area is susceptible to sun damage and other harmful elements that can create sunspots, wrinkles, hyperpigmentation, and more. Therefore, it is important to nourish the neck and décolleté with the same degree of care as the face.

The word "décolleté" can also be used as an adjective to describe a womans garment that is low-cut. It can also be used as a noun to refer to a low-cut neckline.

To care for the décolleté, it is recommended to include it in the overall skincare regimen, including cleansing, moisturizing, and sun protection. Adding a retinol to the regimen can also help improve texture and tone, while reducing fine lines.
