The Neckline Slimmer: A Spring You Bob Your Chin On, with Zero Medical Evidence, Sold to People Who Deserve Better Than a Spring
Claims to slim your neck in 2 minutes a day using spring resistance — a claim supported by exactly zero doctors, zero studies, and zero necks

The Neckline Slimmer is a coiled spring with a chin rest on top. You place the bottom of the spring against your chest, put your chin on the chin rest, and bob your head up and down, compressing and releasing the spring with your chin. That's the exercise. That's the product. You nod at a spring. Repeatedly. For two minutes a day. And the neckline — the area under your chin that you're concerned about — supposedly slims.
It does not slim. It has never slimmed. No dermatologist, plastic surgeon, physical therapist, or person with a medical degree has ever looked at a spring and said, "This will reduce submental fat." You cannot spot-reduce fat with a spring. You cannot spot-reduce fat with anything. Spot reduction — the idea that you can lose fat from a specific body part by exercising that body part — is the most persistent myth in fitness, debunked by every study ever conducted on the topic, and yet it sustains an entire industry of products including the Neckline Slimmer, ab belts, thigh toners, and anything else that promises to shrink one body part through isolated exercise.
The spring provides approximately 0.5 pounds of resistance. Half a pound. Your chin, without the Neckline Slimmer, moves against the resistance of gravity and your own head's weight — approximately 10-11 pounds. The spring adds half a pound of resistance to a movement your head already performs 10,000 times a day (nodding, looking down at your phone, eating). If chin-bobbing against resistance slimmed necks, everyone who looks at their phone would have the jawline of a Greek statue.
The Glorious User Experience

"I bobbed my chin on the Neckline Slimmer for thirty days. Thirty days of dedicated spring-nodding. Two minutes a day. I took before and after photos. I compared them. They were the same photo. My neck was the same neck. The spring had changed nothing. The only difference between day one and day thirty was that I had lost thirty days of two-minute increments to a spring. One star."

“And the neckline — the area under your chin that you're concerned about — supposedly slims”
Click to Tweet"My wife used the Neckline Slimmer in the living room. I walked in. She was sitting on the couch, bobbing her chin up and down on a spring, with the rhythm and expression of a person agreeing very enthusiastically with something nobody was saying. She looked like she was attending an invisible lecture and finding every single point extremely compelling. I asked what she was doing. She said, 'Slimming my neck.' I had follow-up questions. One star."
Sandra from Houston, TX — ★☆☆☆☆
"The spring broke after two weeks. BROKE. The spring that was supposed to transform my neck broke from the stress of being pushed by a chin. My chin defeated the Neckline Slimmer. My chin is apparently stronger than the product designed to strengthen my chin. The chin won. The spring lost. One star."
The Verdict
The Neckline Slimmer is a spring you bob your chin on. It does not slim necks. It cannot slim necks. No spring can slim necks. Neck slimming through chin-bobbing is not a thing that exists in any medical framework, and the 0.5 pounds of spring resistance is less than the weight of the phone you're reading this on.
Chin tucks — a real exercise recommended by physical therapists — are free and actually strengthen neck muscles. CeraVe retinol serum actually improves skin quality over time. And accepting your neck as it is costs nothing and provides immediate relief from spring-nodding.
