Facial Volume Loss & Hollow Cheeks

Home › Skin Concerns › Volume Loss

Facial volume loss is the gradual thinning of fat, collagen and bone support that leaves cheeks, temples and other areas looking hollow, flat or tired. At Yaan Clinic in Gangnam, Seoul, volume loss is restored without surgery using hyaluronic acid fillers for immediate results and collagen stimulators such as Sculptra and Juvelook Volume for gradual, natural-looking change.

What causes hollow cheeks and temples?

Hollow cheeks and temples are usually caused by age-related loss and descent of facial fat pads, thinning collagen and gradual bone resorption. Weight loss, intense exercise, genetics and sun damage can make hollowing appear earlier.

• Temples – hollowing makes the upper face look narrow and the brow tail look heavier.
• Mid-cheeks – flattening makes the face look tired and can deepen smile lines.
• Under the cheekbone – hollows create a gaunt look, especially in slim faces.
• Forehead, chin and under-eye – flat or sunken areas that change facial balance.

Volume loss often contributes to sagging, because the tissues lose the support that held them up. See the sagging skin and jowls guide if drooping is also a concern.

Which treatments restore facial volume?

There are two main approaches: hyaluronic acid fillers, which add volume immediately, and collagen stimulators, which build your own collagen gradually over weeks to months. Yaan Clinic offers both and often combines them.

Treatment at Yaan	Type	Results appear	How long it lasts (as stated by Yaan)
HA filler(Bellast, Restylane, Juvederm)	Hyaluronic acid filler	Immediately	Varies by product; confirmed at consultation
Skin Plus-Hyal	Dissolvable long-lasting HA filler	Immediately	2–3 years
Sculptra	PLLA collagen stimulator	Gradually, over months	About 2 years
Juvelook Volume	PDLLA + HA collagen stimulator	Around 6 weeks	Formula degrades over 1–2 years
Artecoll	Semi-permanent PMMA + collagen filler	Immediately	Over 10 years

Should I choose filler or a collagen stimulator?

Choose filler if you want an immediate result or precise shaping of a small area. Choose a collagen stimulator such as Sculptra or Juvelook Volume if you prefer gradual, natural-looking change across a wider area and are not in a hurry.

Yaan Clinic notes that Sculptra is designed not to overfill, with collagen regeneration noticeable between about 8 and 24 months. Yaan uses one full vial rather than dividing by cc, and a precise mixing system to reduce the risk of nodules. Juvelook Volume, for which Yaan is a "Meister" Key Doctor clinic, does not migrate the way HA filler can.

Is temple and cheek filler safe?

Temple and cheek filler is generally safe when an experienced injector uses careful technique, because these areas contain important blood vessels. Bruising and swelling are common and temporary; serious complications are rare.

Yaan Clinic uses an AccuVein infrared vein finder and blunt microcannulas to reduce vessel injury and bruising, and only genuine products in the correct dosage. Hyaluronic acid fillers can usually be dissolved with hyaluronidase if needed. See genuine products and safety.

Will lifting treatments make my cheeks more hollow?

Some energy devices can reduce fat, so in a slim face they may worsen hollowing if settings are not adjusted. Yaan Clinic tailors energy by area and avoids the mid-cheek where volume is needed.

If you want lifting as well, tell your doctor about any hollowing so your plan balances tightening and volume.

Who is a good candidate for volume restoration?

Good candidates are adults with hollow cheeks, temples or other flat areas who want a fresher, more balanced look without surgery. Yaan Clinic notes that volume and elasticity matter more than age, so people in their 30s can be suitable too.

Share your history of previous fillers, threads or lifting with your doctor. Yaan Clinic states that collagen stimulators and Artecoll can follow earlier HA filler once the type, location and condition of the existing filler have been evaluated.

What combinations does Yaan Clinic suggest?

A common approach is to use filler for structure and a collagen stimulator for overall support and skin quality. Your doctor will confirm the plan.

• Filler plus Sculptra – immediate correction in key points, gradual support across the face.
• Juvelook Volume plus skin booster – volume with improved texture and elasticity.
• Volume plus lifting – filler or collagen stimulator with carefully adjusted lifting for laxity.
