RADIESSEin Gangnam, Seoul
Support and contour, planned in balance. RADIESSE contains calcium hydroxylapatite (CaHA) microspheres in a gel carrier. Treatment considers both tissue support and a collagen response. At QD Clinic in Gangnam, Seoul, South Korea, your goals and skin assessment guide the product, area and recovery plan.


Who it’s for
- Discuss changes in facial support, contour and firmness. Skin thickness and the specific treatment goal guide the plan.
- Undiluted and diluted uses have different goals and cannot be described as having the same effect. Because CaHA is not readily dissolved with an enzyme the way HA filler is, choosing the treatment area carefully is important.
Suitability requires an examination. Skin thickness, health and previous procedures may make a different approach more appropriate.

THE MECHANISM, STEP BY STEP
01The product and material
RADIESSE contains calcium hydroxylapatite (CaHA) microspheres in a gel carrier. Treatment considers both tissue support and a collagen response.
02Checking your skin
Discuss changes in facial support, contour and firmness. Skin thickness and the specific treatment goal guide the plan.
03What sets it apart
Undiluted and diluted uses have different goals and cannot be described as having the same effect. Because CaHA is not readily dissolved with an enzyme the way HA filler is, choosing the treatment area carefully is important.
04Assessing the change
Collagen-stimulating treatments are assessed over weeks to months. Fullness on the treatment day does not establish the final effect.
Treatment areas
- Areas to assess
What the procedure is like
- 1Tell us whether contour support or skin firmness is your priority. Previous CaHA or HA filler, collagen stimulators, thin skin and existing lumps affect selection. Eye and lip areas require separate consideration.
- 2Undiluted and diluted uses have different goals and cannot be described as having the same effect. Because CaHA is not readily dissolved with an enzyme the way HA filler is, choosing the treatment area carefully is important.
- 3After appropriate comfort measures and cleansing, the doctor treats the agreed areas.
- 4Watch for bruising, swelling and tenderness, as well as lumps or uneven areas that persist. CaHA cannot simply be dissolved with an enzyme the way HA filler can. Pressure and massage instructions depend on how the product was actually used; do not apply another filler’s aftercare on your own.
Appointment length depends on consultation, numbing and treatment extent. Tell us your available time and important plans when booking.
Recovery & aftercare
- Avoid strong irritation, overheating and strenuous exercise while the skin settles. Follow your instructions for washing and makeup.
- Massage and pressure advice differs by product. Follow your clinician’s instructions rather than another product’s routine.

Review RADIESSE
RADIESSE used for structural support and diluted use for skin quality have different goals. We distinguish early shape from the later collagen response and review the agreed contour or firmness target. At review we also check for lumps or surface unevenness that remain after bruising and swelling have settled.
Next steps
Even with the same RADIESSE, the number of sessions differs depending on whether it is used undiluted or diluted. Purpose, skin thickness, area and the first response guide further treatment. Remaining swelling should settle before judging an apparent shortfall.
