I have a somewhat sun-damaged decolletage (thanks, most women's clothes, for all having v-necks and low cuts!) but this serum just sinks into it and in just one week has made it look less wrinkled. It also feels less parched, which is the biggest win for me - no more stretched and itchy feeling at the base of my neck. It's a little tricky to balance the right squeeze to get the product out onto the three massaging heads (with the amount of pressure I'm exerting on the tube, I always worry that it's just going to explode everywhere), but it's a great product and I'll definitely buy it again (and again and again...)
