Pain Control Through Cooling and Immediate Pore Tightening on the Skin's Surface
A powerful cooling system operates in real time to dramatically reduce pain, while effectively tightening pores that appear loosened on the skin's surface.
COOLFASE
Cool and precise from deep within the skin, COOLFASE.
Powerful Surface Cooling & Pore-Level Collagen Regeneration
Coolfase lifting rapidly cools the epidermis to sub-zero temperatures, safely blocking treatment pain and skin irritation, while delivering powerful radiofrequency energy in close contact deep into the dermis. It intensively stimulates collagen regeneration around loosened pore roots, offering a next-generation anti-aging solution that reduces facial swelling right after the procedure while delivering a tightening effect that builds density from within the skin.
Improved Elasticity Through Radiofrequency Energy Reaching Deep into the Dermis
Powerful radiofrequency energy precisely penetrates deep into the skin layers, densely activating surrounding collagen and improving overall elasticity.
Preventing Facial Sagging and Improving Fine Lines Through the Spread of Collagen Remodeling
Collagen fibers activated by radiofrequency stimulation spread throughout the skin layers, and through this process, sagging and fine wrinkles are improved.
Coolfase RF Lifting's 3 Key Mechanisms
CRYO-RF COUPLING
Simultaneous implementation of superficial cooling and deep heat transfer
The skin's surface is rapidly cooled to sub-zero temperatures to safely control pain receptors, while powerful radiofrequency energy penetrates deep into the dermis at the same time. This precise combination of heat and cold achieves lifting with no side effects.
VOLUME TIGHTENING
Instant contraction and swelling relief of collapsed contours
Radiofrequency energy tightly consolidates loosened dermal tissue, inducing a tightening effect that refines the facial contour immediately after the procedure. At the same time, the cooling energy supports circulation, quickly reducing fine facial swelling.
COLLAGEN FIBER REMODELING
Spontaneous retuning of denatured collagen
Uniform thermal effects are delivered throughout the dermis, stimulating the contraction and mass regeneration of aged, weakened collagen fibers. Over time, the skin's internal support structure becomes firmer, restoring its natural firmness and smooth texture.
Procedure time
Approximately 10 to 20 minutes
Treatment area
Front face and irritated local area
recovery time
Can return to daily life immediately
Treatment cycle
1 - 2 times a week
(maintain after initial intensive care 4 to 5 times)
Coolfase: The Distinction of the Tip
The differentiated effect of Coolfase lifting begins with the technology of a genuine tip opened exclusively for each individual patient. We use only single-use genuine tips approved by the Ministry of Food and Drug Safety (MFDS), thoroughly guaranteeing hygiene and safety. A patented overheat-prevention device delivers powerful radiofrequency energy quickly and without irritation, dramatically reducing the burden of treatment time and pain concerns.
Reducing Treatment Burden
Through Overheat-Prevention Technology
A patented device built into the tip delivers radiofrequency energy safely and quickly, preventing skin irritation and reducing the burden of treatment time.
Adherence to the Principle of
MFDS-Approved, Single-Use Genuine Tips
We use only genuine Coolfase-exclusive tips approved by Korea's Ministry of Food and Drug Safety (MFDS), strictly adhering to the principle of single-use consumables for each individual patient to ensure hygiene.
LIEUL Coolfase Personal Lifting Plan
Personalized aftercare is tailored differently for each individual, based on the day's skin condition, oil-moisture balance, and the level of irritation right after the procedure. Rather than a one-size-fits-all approach, we provide a customized soothing and regenerating solution precisely calibrated to your skin's own recovery pace.

COOLFASE Q&A
Is Coolfase truly painless even without anesthesia?With Coolfase, the moment radiofrequency (RF) energy is emitted, a powerful sub-zero cryo-cooling system wraps around the epidermis in real time, effectively controlling nerve stimulation. Instead of pain or a hot burning sensation, you'll feel a pleasant coolness and can undergo the procedure comfortably without anesthesia.
How is it different from other radiofrequency devices like Oligio or InMode?Conventional RF lifting delivers heat through the epidermis, which can come with the risk of burns and pain. Coolfase, on the other hand, combines cooling technology to block epidermal irritation at the source. It's further differentiated by its unique de-bloating effect, which immediately reduces swelling and refines facial contours right after the procedure.
When do results appear, and how long do they last?Right after the procedure, you can feel a clear facial-line refining effect from reduced swelling due to the cooling effect, combined with immediate tissue contraction from the radiofrequency energy. Over the following 2 to 4 weeks, collagen in the dermis continues to remodel, further building elasticity, which typically remains flexible for several months depending on individual skin condition.
Precautions after treatment
Any temporary coolness or tingling in the skin caused by the precision cooling energy will naturally return to normal temperature within a few hours.
To preserve the collagen-regenerating effect of the radiofrequency heat delivered deep into the dermis, avoid saunas, steam rooms, and excessively hot baths for about 3 to 5 days after the procedure.
As internal cells become activated, the skin may become temporarily dry, so be sure to apply moisturizing and regenerating creams generously to keep the skin hydrated.
To protect the skin barrier during recovery and help the treatment results settle in stably, be sure to apply sunscreen thoroughly whenever going outside.
To prevent irritation to the skin's surface, avoid alcohol-based cosmetics, peeling products, and scrubs for one week after the procedure, and refrain from strong lymphatic massage.
