Carol Ann, neck lines are a big challenge! I would recommend a heavy-duty moisturizer like our Firming Densifier. Use it both AM and PM to help firm the area up. Also, our necks get tons of sun that we don’t notice. Protect the area diligently with sunscreen to prevent further damage and give your skin a chance to repair itself. Also, remember to apply any serum you use on your face to your neck. The Transforming Infusion would probably be best due to the high niacinamide content. Combining it with the Firming Densifier should help quite a bit. I’d say it will take about two months to see real results.
