The neck is a delicate area and can show signs of aging from wrinkles to sagging skin.

Since the skin on the neck is so delicate, it might be the best idea to just bring your face routine down to the neck.

The neck is so delicate and deserves a little more attention:

"It's thinner and it doesn't contain the same oil composition as the face does, so it's more prone to irritation. It's also more prone to wrinkles and dryness since it doesn't have that same oil protection."
