Can I combine Ellansé and an HA skin booster in one visit?

Clinics sometimes offer both in the same course since they target different layers and goals, volume versus hydration, but this depends on the practitioner's assessment of the treatment areas and spacing between injections.

How soon can I fly home after treatment?

For Ellansé, practitioner guidance suggests waiting about 1 to 2 weeks before flying due to the risk of swelling from cabin pressure. For HA skin boosters, there is no formal published rule, but a caution period of 24 to 72 hours is often advised.

Will I need more than one trip to Seoul to complete treatment?

Ellansé is often done in a single session, so one trip may suffice. HA skin boosters are given as a course of about 3 sessions over several weeks, which may require multiple visits or a longer single stay.

Is Ellansé permanent?

No. Manufacturer materials describe it as bioresorbable, with duration depending on the product grade, ranging from about 1 to 4 years, and results vary by individual and injection site.

Which lasts longer, Ellansé or an HA skin booster?

Ellansé lasts longer, with published or extrapolated durations up to several years depending on the product grade, while HA skin boosters show effects lasting a matter of months.

Question: Should I get Ellansé or an HA skin booster at a Seoul clinic?
Treatments compared: Ellansé, HA skin booster

Comparison

	Ellansé	HA skin booster
What it is	A filler made of polycaprolactone (PCL) microspheres, 25 to 50 micrometers, suspended in a carboxymethylcellulose gel carrier	A hyaluronic acid based injectable designed to hydrate and smooth skin texture rather than add volume; some products use polynucleotides instead of HA
How it works	The CMC gel gives immediate volume, then degrades as PCL particles stimulate the body's own collagen production over time	HA binds water in the mid dermis to improve hydration and smoothness; polynucleotide versions aim to support the skin's own repair processes
Sessions	Often 1, sometimes repeated once after several months depending on area and product grade	A course of 3 sessions, spaced 2 to 4 weeks apart, though single-session HA products also exist
Downtime	Mild swelling or bruising at injection points for a few days; normal activity resumes the next day	Minimal; redness or small bumps settle within hours to 1 to 2 days
Flying after	Clinics and injector guidance suggest waiting about 1 week, with some recommending 2 weeks before flying	No specific published wait time; general caution of 24 to 72 hours is advised, but this is practice guidance, not a formal rule
How long it lasts	Depending on the product grade (S, M, L, E), published or extrapolated duration ranges from about 1 to 4 years	Effects are shorter, lasting several months up to about 9 months for some HA products
Regulatory status	Manufactured by Sinclair/Sinclair Pharma, marketed in over 60 countries and regions; specific MFDS approval status in Korea was not confirmed in public sources checked	Individual HA and polynucleotide skin boosters have separate device registrations by product and country; for example, SKINVIVE by Juvederm (sold as Volite outside the US) has US FDA premarket approval since 2023
Suited for	Volume loss and longer-term collagen support in areas like cheeks, temples or jawline	General skin hydration, texture and glow, often used as a maintenance or add-on treatment
Evidence base	Supported by peer-reviewed studies on PCL induced neocollagenesis and long-term volumizing effect	Supported by manufacturer-funded clinical trials for specific HA products showing improved smoothness up to 6 months and hydration up to 9 months
