Detailed answer

Eye cream is specifically formulated for the delicate skin around the eyes, which is thinner and more prone to dryness and wrinkles. The skin on the neck is thicker and has different needs than the delicate eye area. It is recommended to use products specifically designed for the neck and décolletage, which usually have different ingredients and textures that cater to the thicker skin in those areas. Using eye cream on the neck may not provide the desired results and could potentially cause irritation or other adverse effects.
