Creates a solid triple foundation of skin, fat, and fascia

Eternal Youth Skin Solution 

Only at YELINE

YELINE focuses not just on appearance,

but first on the structural balance

beneath the skin 

Simply lifting the visible face is not enough. If the internal balance of bone, muscle, ligaments, fat, and cells is disrupted, even the best procedures can lead to sagging and imbalance again over time 

Doctor’s 1:1 Consultation-Based

Personalized Treatment Design

With over 20 years of clinical experience, Dr. Hwang Ui-Kyung analyzes each patient’s unique facial anatomy—facial asymmetry, skin thickness, and elasticity loss—to design fully personalized procedures 

PRP Fat Grafting 

YELINE’s unique solution that goes beyond filling fat, promoting skin regeneration and elasticity

The most critical factor in fat grafting is

“how much survives”

Fat grafting is a procedure that transfers autologous fat from other areas of the body (e.g., abdomen or thighs) to the face. Once injected, the fat is not yet vascularized and must survive by absorbing oxygen and nutrients from the surrounding tissue 

Fat cells that fail to connect to blood vessels will either be reabsorbed or die, resulting in volume loss, irregular texture, or uneven contours

PRP acts as a 'graft booster' by helping the transplanted fat cells survive 

PRP-enhanced fat grafting promotes faster blood vessel formation, protects against cellular damage, and regulates inflammation, helping the fat survive as part of your own tissue

  Stimulates new capillary formation  

  Protects cell membranes from damage

  Enhances elasticity and skin texture  

Boot-up Treatment 

A highly effective skin regeneration protocol based on 20 years of clinical experience Combining PRP + Collagen Stimulator (Juvelook) + PN for optimal synergy

Unique Boot-Up Formulation Technique Stimulates collagen directly to fortify the scaffold layer

YELINE’s Boot-Up treatment is

not a basic PRP injection

This formulation combines PRP with high-molecular ingredients that stimulate collagen directly. It promotes stem cell activation, immune regulation, and collagen regeneration all at once, helping the skin naturally recover elasticity and volume beyond simple filling 

Not a generic blend, but a science-backed ratio 
verified in thousands of clinical cases 

Based on over 5,000 procedures, Director Hwang has established an optimal ratio of PRP and collagen-based PDRN. This protocol delivers results that are more natural and longer-lasting than conventional skin boosters 

Over 90% patient satisfaction Combines 

natural volume and tissue regeneration 

Ideal for those seeking deep structural improvement in volume and elasticity, this treatment shows high satisfaction. Yeline’s Boot-Up technique yields natural results that improve over time

FIT-VOL Injection 

Exclusively at YELINE

Personalized volume that

fits your face naturally 

Natural yet Long-Lasting Volume Skin

that moves naturally without stiffness 

FIT-VOL uses autologous PRP and collagen to gradually stimulate regeneration within the skin, resulting in a natural look evenwith facial expressions and a sense of restored skin texture and volume

If you get fillers regularly, 

FIT-VOL is the clear choice 

While conventional fillers simply fill hollow areas, FITVOL stimulates your skin to regenerate volume naturally. Even after the visible effects fade, the skin continues to strengthen and improve from within
