Aging, poor posture, and a lack of skin care can all cause neck lines. The creases across the neck are unsightly, make you look older, and are even ranked in online polls among the hardest lines to get rid of. This article explains the four types of neck lines and what causes them, and which aesthetic medicine treatments can smooth away stubborn neck lines in addition to daily care and prevention.
3 Types of Horizontal Neck Lines and Their Causes
1. Aging-Related Neck Lines
With age, the collagen and elastic fibers in the dermis of the neck gradually break down, and the keratinocytes in the epidermis age, so the creases sink in and grow deeper. The skin on the neck also has fewer sebaceous glands than other areas, so it dries out more easily, and prolonged dehydration or UV damage makes neck lines more pronounced. Sun exposure, dryness, and friction can all age the skin and cause horizontal neck lines.
2. Fat-Related Neck Lines
These neck lines are mostly caused by obesity or genetic factors that lead to excess subcutaneous fat, with fat building up and stacking over time, forming layers of fat around the neck like a “swim ring.” The skin is squeezed into folds, which slowly become true neck lines.
3. Posture-Related Neck Lines
Constantly looking down at your phone, or sleeping on your side or stomach, keeps the neck bent for long periods. This compresses the skin of the neck and keeps the neck muscles from relaxing, and once the skin has been creased, neck lines form naturally. At first, posture-related neck lines are “dynamic” lines, but if poor posture is kept up for a long time, they become “static” lines, and the neck lines are visible even when you are not moving.
Causes of Vertical Neck Lines (Turkey Neck)
The superficial muscle layer of the neck runs vertically down to the collarbone. This muscle, the platysma, is controlled by the facial nerve, so it also moves whenever you make facial expressions. If the platysma contracts too much or becomes too tight, vertical neck lines form easily, commonly known as turkey neck. They gradually appear in most people after age 45, but for some people it is genetic: a platysma with stronger tension or greater development produces obvious vertical neck lines.
Everyday care can help prevent neck lines from forming, but once they appear, it takes a lot of effort to smooth them out, and ordinary skin care products can rarely remove them. If neck lines bother you, you can consider the aesthetic medicine treatments below.
Horizontal Neck Line Treatment: Filler Injections
1. Hyaluronic Acid Filler
Injecting small-molecule hyaluronic acid fills depressions and smooths fine lines, and it also hydrates the skin, which in turn improves neck lines. Results usually last 8-12 months, so regular touch-ups are needed. The filler also should not be overinjected, or the skin may become uneven.

2. Collagen Stimulators
- AestheFill
AestheFill is made from a new type of ingredient, poly-D,L-lactic acid (PDLLA). Starting 1 month after injection, it continues to stimulate the body to produce about 1.5-2 ml of its own collagen, more collagen than either Ellansé or Sculptra produces. This abundant collagen quickly restores the skin's elasticity and brings back plump, full skin.
- Sculptra
Sculptra is mainly composed of poly-L-lactic acid (PLLA). Once injected into skin tissue, it stimulates the body's fibroblasts over about 4-6 weeks to produce new collagen fibers. As collagen increases, the skin looks fuller, and deep wrinkles and hollows are reduced.

- Ellansé
Ellansé is mainly made of “70% CMC gel + 30% PCL microspheres,” a medical-grade polymer that the body can fully absorb and that induces its own new collagen. After Ellansé is injected under the skin, the CMC gel immediately fills depressions; as the body gradually metabolizes and absorbs the CMC gel, the PCL microspheres keep working and stimulate the tissue to produce collagen. The new collagen tissue completely replaces the original CMC gel and PCL microspheres, leaving the skin smooth and natural while maintaining its elasticity.

Horizontal Neck Line Treatment: RF and Ultrasound Lifting
For a neck with mild laxity and aging, RF and ultrasound lifting can be used. These non-invasive treatments induce new collagen and elastin remodeling, which improves neck laxity, softens fine lines, and firms the skin.
1. Morpheus8 Microneedle RF
MORPHEUS8 is the newest “microneedle RF” treatment, combining the characteristics of microneedling and radiofrequency. Ultra-fine gold-plated microneedles first create controlled injury in the epidermis and dermis to trigger the skin's regenerative response, while the needle tips deep in the skin continue to release RF energy. Because the energy is released in the deeper layers of the skin, and the probe tip has a non-insulated design, the epidermis is not heated. This lets the deep dermis be heated more safely and precisely to stimulate collagen and elastin production for lifting, tightening, and wrinkle reduction, and it is the most effective option for treating neck lines.

2. Thermage FLX
Thermage FLX uses monopolar RF technology. Wireless high-frequency RF waves that oscillate about 6 million times per second provide wide-area “3D volumetric heating,” delivering 55-65°C heat into the dermis and subcutaneous tissue, where collagen is most abundant, to stimulate the regeneration of the body's own collagen and elastin. The RF energy triggers the body's natural repair response, thereby reducing wrinkles, fine lines, and sagging.

3. 4th-Generation Ultraformer MPT
The all-new 4th-generation Ultraformer MPT uses the principle of high-intensity focused ultrasound (HIFU) to concentrate 65-75°C heat at a targeted depth. Besides causing immediate contraction, these tiny thermal coagulation points stimulate collagen remodeling and regeneration, so the skin tissue gradually regains its elasticity one to three months after the procedure, and can even achieve a firmer, more defined contour.

Vertical Neck Line Treatment: Botulinum Toxin
Botulinum toxin injections help relax the neck muscles and reduce the fine lines and wrinkles caused by facial expressions or skin tension. The treatment is especially effective for vertical neck lines caused by long-term overuse or frequent contraction of the neck muscles, and treating once every 4-6 months can make turkey neck less noticeable and help prevent static neck lines from forming.
Recommended botulinum toxin brands: Neuronox, BOTOX
