What is Linear Z?

Linear Z is an upgraded version of the Linear Firm device. Instead of placing individual focused points, it sweeps energy in continuous lines, which allows denser, faster delivery. According to the manufacturer, 100 shots can be completed in well under a minute.

Energy creates coagulation zones at several depths, including the upper and mid dermis, the subdermal layer and the SMAS. The tissue responds by rearranging collagen and elastin, which may gradually improve firmness, lift and fine wrinkles.

Who it's for

Linear Z may suit people concerned about:

• Overall facial laxity and loss of elasticity
• Uneven or blurred facial contours
• Double chin and jowls
• Lines and loose skin on the neck
• Laxity on the upper arms, thighs or abdomen
• Wanting V-line definition with little disruption

How we treat it at Egg Clinic

Your doctor selects cartridges by depth and plans how many lines to place in each area. The linear delivery allows even coverage on broad surfaces and efficient treatment of the body.

Facial areas include the full face, facial contour, double chin and neck. Body areas include the arms and upper arms, thighs and abdomen. Deeper and shallower passes are often layered for a more thorough effect.

What to expect

Your appointment starts with a consultation. Numbing cream is applied to the face, and the treatment takes about 20 to 30 minutes. You may feel warmth or brief prickling.

Makeup and face washing are usually fine right afterward. Temporary tingling, swelling, bruising or redness can last several days.

Firmness develops progressively as collagen remodels. Sessions are commonly spaced 1 to 3 months apart depending on the area and your goals. Results vary.

Aftercare

• Use sunscreen, moisturizer and antioxidants such as vitamin C
• Avoid saunas, alcohol, peels and scrubs for one week
• Wash with lukewarm water for 3 days
• Resume normal exercise once tenderness settles
• Contact the clinic if bruising or swelling persists

Frequently asked questions

What is the difference between line and dot HIFU?

Dot-type HIFU places separate focal points, while line-type delivery sweeps energy continuously, allowing denser coverage in less time. Both aim to stimulate collagen.

Can Linear Z be used on the body?

Yes. It can be used on areas such as the upper arms, thighs and abdomen to help improve skin firmness.

Is it painful?

Most people feel warmth or tingling. Numbing cream is used on the face, and settings can be adjusted to your comfort.
