Treating the neck and décolleté with skincare at home is important because this area is often overlooked in daily routines but is highly susceptible to visible signs of aging. The skin on the neck and chest is thinner, more delicate, and has fewer oil glands, making it more prone to dryness, creasing, and the formation of fine lines and wrinkles. As we age, collagen production in these areas decreases, leading to sagging and the appearance of horizontal lines. Additionally, the neck and décolleté are frequently exposed to sun damage, which accelerates aging and causes pigmentation issues.
