Pain Control Through Cooling & Immediate Pore Tightening
A powerful cooling system operates in real time to significantly reduce treatment discomfort while effectively tightening visibly enlarged pores on the skin’s surface.
COOLFASE
Coolfase: Advanced Cooling RF That Firms from Within
High-Density Cooling RF That
Builds Firmness Without Pain
Coolfase lifting rapidly cools the epidermis to sub-zero temperatures, safely minimizing treatment-related pain and skin irritation while delivering powerful RF energy directly and precisely into the deeper dermal layers. By intensively stimulating natural collagen production around the roots of enlarged pores, it provides immediate facial de-bloating after treatment along with a dense, firming effect that builds from within the skin, offering a next-generation anti-aging solution.
Improved Firmness Through RF Energy Reaching Deep into the Dermis
Powerful RF energy precisely penetrates the deeper layers of the skin, densely activating surrounding collagen and improving overall skin firmness.
Preventing Facial Sagging & Improving Fine Lines Through Collagen Remodeling
Collagen fibers activated by RF stimulation spread throughout the skin layers. Through this process, the appearance of sagging and fine lines is improved.
The 3 Key Mechanisms of
Coolfase RF Lifting
CRYO-RF COUPLING
Simultaneous Epidermal Cooling and Deep Thermal Energy Delivery
The skin surface is rapidly cooled to sub-zero temperatures to safely control pain-sensitive nerves, while powerful RF energy is delivered deep into the dermis. By precisely combining heat and cold, Coolfase provides a comfortable lifting treatment with reduced treatment burden.
VOLUME TIGHTENING
Immediate Contouring and Reduction of Facial Swelling
RF energy densely contracts loose dermal tissue, creating an immediate tightening effect that helps refine facial contours after treatment. At the same time, the cooling energy helps support circulation and reduce mild facial swelling.
COLLAGEN FIBER REMODELING
Natural Retuning of Altered Collagen Fibers
Uniform thermal energy is delivered throughout the dermal layer to stimulate the contraction and regeneration of aged, weakened collagen fibers. Over time, the structural support within the skin becomes firmer, restoring its natural resilience and smooth skin texture.
Treatment Time
Approximately 10–20 minutes
Treatment Areas
Full face and localized areas requiring treatment
Downtime
Immediate return to daily activities
Recommended Treatment Interval
1–2 times per week
(Intensive care for the first 4–5 sessions, followed by maintenance treatments)
What Makes Coolfase
Tips Special
The distinctive results of Coolfase lifting begin with the technology of genuine tips opened exclusively for each individual patient. Only single-use, genuine tips approved by the Korean Ministry of Food and Drug Safety are used to ensure strict hygiene and safety. A patented overheating prevention device rapidly delivers powerful RF energy while minimizing skin irritation, significantly reducing both treatment time and discomfort.
Reduced Treatment Burden Through Overheating Prevention Technology
The patented device built into the tip delivers RF energy safely and rapidly, helping prevent skin irritation while reducing treatment time.
Strict Use of MFDS-Approved Single-Use Genuine Tips
Only genuine Coolfase tips approved by the Korean Ministry of Food and Drug Safety are used. To ensure hygiene, each tip is strictly designated as a single-use consumable for one patient only.

COOLFASE Q&A
Is Coolfase really comfortable enough to be performed without anesthesia?At the moment RF energy is delivered, Coolfase’s powerful Cryo cooling system rapidly cools the epidermis to sub-zero temperatures in real time, effectively controlling nerve stimulation. Instead of pain or an intense sensation of heat, you can experience a pleasant cooling sensation and undergo the treatment comfortably without anesthesia.
How is Coolfase different from other RF devices such as Oligio or InMode?Conventional RF lifting treatments deliver thermal energy through the epidermis, which can be accompanied by pain and concerns about burns. Coolfase combines RF energy with cooling technology to significantly reduce epidermal irritation. It also offers a distinctive de-bloating effect, helping reduce facial swelling immediately after treatment and refine facial contours.
When do the treatment effects appear, and how long do they last?Immediately after treatment, you may notice a visibly more defined facial contour as the cooling effect helps reduce swelling and RF energy induces immediate tissue contraction. Over the following 2–4 weeks, collagen remodeling in the dermis continues to improve skin firmness. Depending on individual skin condition, the results can be maintained flexibly for several months.
Post-Treatment Care
Temporary coolness or a tingling sensation caused by the precise cooling energy immediately after treatment will naturally subside and the skin will return to its normal temperature within a few hours.
To help maintain the collagen-regenerating effects of the RF thermal energy delivered deep into the dermis, avoid saunas, jjimjilbangs, and excessively hot baths for approximately 3–5 days after treatment.
As the cells within the skin become activated, temporary dryness may occur. Apply sufficient moisturizing and regenerative creams to keep the skin well hydrated.
To protect the recovering skin barrier and help stabilize the treatment results, be sure to apply sunscreen thoroughly whenever going outdoors.
To prevent irritation to the skin surface, avoid alcohol-containing skincare products, peeling products, and scrubs for one week after treatment. Strong facial massage or meridian massage should also be avoided.
