This area tends to show change before the face does, for reasons that are anatomical rather than anything to do with how well it has been looked after. Here is what is happening — and one caution specific to the neck.
The neck and jawline tend to show change earlier than the face, and people often notice it there first. The reasons are anatomical rather than anything to do with how well the area has been looked after.
If you have noticed the jawline and under-chin area look different first thing than they do later in the day, that is fluid, redistributing as you become upright and move. It is not a change in your skin — and knowing this is genuinely useful, because it stops you judging any product by how you look at seven in the morning.
The massage component has a plausible role here, given how much lymphatic drainage converges in the neck. Reduced puffiness is the effect people most commonly report first, and this is the area where it tends to be most visible.
The light component targets the collagen side, gradually and modestly, over weeks to months.
The thyroid gland sits at the front of the neck. As a general precaution, avoid treating directly over the front of the throat, and speak to your doctor first if you have any thyroid condition. Also avoid the immediate eye area entirely and never look into the light source. Our safety page has the complete list of cautions.
Skin here is drier and thinner than on the face — glide matters more, and dragging matters more.
This follows the direction of lymphatic drainage towards the nodes near the ear.
Again following drainage direction. Stay to the sides — avoid the front of the throat.
This is the thinnest skin you will use it on. Almost no pressure. If it feels like dragging, add more serum.
Two habits do more for this area over a decade than any device will, and one of them is free:
Neither is exciting, and neither has a marketing budget. Both have better evidence behind them than anything else discussed on this site.
