Hello. I'm Dr. Jung Huh, Chief Director of Ruby Dermatology Clinic, where we restore natural skin health and a dimensional look suited to each person's anatomy.

"As I age, my cheeks are hollowing and the marionette lines at the corners of my mouth are getting deeper, making me look sad. I'm concerned about graft survival and foreign-body feeling with fat grafting, and I'm worried regular fillers will turn lumpy. Which choice is right for me?"

This is a question I often hear from people who come to me worried about volume loss and contour changes after middle age.

The days of blindly filling hollow areas with a physical substance are over. Once you clearly understand the difference between Juvelook Volume, which prompts your own skin to produce collagen and form natural volume, and fat grafting, which uses your own tissue, you can restore a youthful, firm facial contour without looking awkward.

💡 [3-Point Summary]

Fat grafting: Fat harvested from the thighs or abdomen is injected. Initial volume is reliable, but there are risks of variable graft survival, clumping and sagging.

Juvelook Volume (PDLLA + HA): A polymeric PLA particle that induces your own collagen production, creating not artificial volume but natural volume that builds up from within your own skin, along with improved elasticity and texture.

Criteria for choosing: If you need large-volume, immediate contour reconstruction, fat grafting is the choice; if you want gradual, smooth, natural results with no foreign-body feeling in hollow cheeks, marionette lines and nasolabial folds, Juvelook Volume is the better fit.

A. Why Juvelook Volume? The Anatomical Principle of a Collagen-Regenerating Skin Booster

Loss of volume is caused not only by simple fat loss but by a combination of reduced dermal collagen and weakening of the subcutaneous fat layer and fascia (SMAS).

How PDLLA (poly-D,L-lactic acid) induces your own collagen:

Juvelook Volume's PDLLA particles, which have a porous network structure, settle in the subcutaneous fat layer and lower dermis and stimulate fibroblasts. Over the several months in which the particles slowly break down, newly formed collagen firmly builds up the empty space.

Volume that doesn't look artificial:

Unlike conventional fillers, it does not stay in lumps that move or clump, and because your own tissue regenerates, it looks very natural and soft when you make expressions.

C. A Guide to Choosing the Right Treatment for You

1) When Juvelook Volume is recommended

People with hollow cheeks, temples, nasolabial folds or marionette lines who need a natural-looking fill

People who are uncomfortable with foreign material or fillers and want to fill in the skin texture smoothly and densely with their own collagen

People who are bothered by fat-harvesting surgery or long downtime

2) When fat grafting may be considered

When large-volume, immediate contour reconstruction is needed across the whole face

When you are comfortable with fat harvesting and can accept the swelling during the graft-healing process

D. Recovery and Duration of Results

Treatment interval: For Juvelook Volume, we recommend 3 sessions at 1-month intervals as the standard protocol.

Duration of results: The collagen volume your body produces lasts 1.5 to 2 years or more, and the particles are fully broken down into water and carbon dioxide and eliminated from the body.

E. 🔥 Completing Volume & Elasticity: the 'Ruby Dual Volume Layering' Synergy

Juvelook Volume + Ulthera / Thermage:

After tightening the sagging contour framework and skin with Ulthera or Thermage, filling in collagen in the hollowed areas with Juvelook Volume creates an anti-aging synergy that delivers lifting and volume at the same time.

Juvelook Volume + Skin Botox:

Deep volume is filled with Juvelook, while fine lines and pores on the surface are refined with skin Botox, creating a dimensional, dense skin foundation.

F. Dr. Jung Huh's Practical Know-How & Clinical Insights

What matters most in Juvelook Volume treatment is 'a precise nodule-prevention hydration (reconstitution) protocol' and 'a multi-layer cannula injection technique that follows the anatomical grain.'

Several days before treatment, I prepare the product by mixing purified water and HA in an optimal ratio so the PDLLA particles form a uniform three-dimensional network structure. During treatment, I use a blunt-tip, high-quality cannula instead of a sharp needle to avoid vascular injury, and I apply the '3D dual-layer vector injection technique,' placing the product densely, layer by layer, in the subcutaneous fat layer and above the fascia. This greatly reduces the risk of nodules while firmly restoring each person's natural dimension.

📌 [Final Notes] Pre- and Post-Treatment Precautions

Treatment-area massage: To help the particles spread evenly and your own collagen form well, gently massage the area for the period your clinician advises.

Avoid alcohol and saunas: To minimize irritation of the injection area and support collagen formation, avoid alcohol, smoking and steam rooms for one week.

Drink plenty of water: Drink at least 1.5 L of water a day to support the collagen hydration reaction and skin regeneration.
