What is Coolfase?

Coolfase delivers radiofrequency (RF) energy into the dermis to heat collagen-rich tissue. The heat encourages collagen to contract, regenerate and remodel, which may improve firmness and elasticity over time.

A patented direct contact cooling system chills the skin surface throughout treatment. This helps protect the epidermis and allows RF energy to be delivered steadily to the deeper layers, which many patients find makes the experience more comfortable.

Who it's for

Coolfase may suit people concerned about:

• Sagging along the jawline and lower cheeks
• Loss of elasticity and fine lines
• Nasolabial folds and marionette lines
• Laxity around the eyes and forehead
• A double chin or softening contour
• Having avoided lifting because of discomfort

How we treat it at Egg Clinic

Your doctor maps the face and applies the cooled handpiece in a stamping pattern, with each pulse combining surface cooling and deep heating. Energy is planned for each area according to skin thickness and laxity.

Treatment areas include the forehead, eye area, the front, side and deep cheeks, double chin, neck, nasolabial folds, facial contour and marionette lines. Coolfase can be used alone or combined with focused ultrasound treatments.

What to expect

Following a consultation, numbing cream may be applied, though many people find the cooling keeps treatment comfortable. Sessions take about 15 to 30 minutes.

Light makeup is possible right after treatment, with your full routine from the next day. Mild swelling or tenderness may persist for 3 to 7 days depending on your response.

Improvement tends to build gradually over several weeks. Many patients repeat treatment every 3 to 6 months. Results vary.

Aftercare

• Avoid alcohol, smoking, strenuous exercise, saunas and hot baths for one week
• Apply a recovery cream regularly to prevent dryness
• Use sunscreen consistently when outdoors
• Keep skincare gentle for a few days
• Contact the clinic if swelling or tenderness persists

Frequently asked questions

Why is cooling important?

Cooling protects the skin surface while heat is delivered deeper, which helps with comfort and supports safe energy delivery.

Is there any downtime?

Most people return to normal activities right away. Some experience mild swelling or tenderness for several days.

How is it different from HIFU?

Coolfase uses radiofrequency to heat the dermis broadly, while HIFU focuses ultrasound at specific depths. They are sometimes combined for layered results.
