Can I use this on my neck, chest, and hands, or is it just for the face?

Yes, this serum is well suited for use beyond the face. The directions specifically mention the throat area as a primary application zone, and many users extend it to the décolleté, jawline, and hands — all areas where skin can lose firmness and tone over time. The lightweight formula absorbs quickly without residue, making it practical to apply to larger areas without a greasy or heavy feel. The same firming and tightening action that benefits the face and jawline applies equally to sun-damaged or crepey skin on the chest and hands. Apply the same way as you would on the face — massage in gently and allow to absorb fully before layering other products on top.
