How many ml does a liquid facelift take?
Short answer: There is no single “right ml” for a liquid facelift. With collagen-stimulating PLLA the amount is planned in vials, not ml: for the face usually 1 vial per session, 2–3 sessions 4–6 weeks apart. With CaHA the face usually takes 1–2 syringes (1.5 ml), diluted. The exact amount is set at consultation based on volume loss and skin structure.
Why can’t it be stated in ml?
“Liquid facelift” is not a single product name. The answer to “how many ml” changes with the product, its preparation and the goal. PLLA, for example, is a powder reconstituted with sterile fluid before use; most of the injected volume is this fluid, which is absorbed within a few days.

PLLA: how many vials and sessions?
- Current consensus recommends reconstituting one vial with about 8–16 ml of fluid.
- The face usually takes 1 vial per session; more may be needed with marked volume loss.
- Sessions are usually 4–6 weeks apart; most people need 2–3.
- Early fullness is fluid and swelling; the real effect develops over weeks and months.

CaHA: how many syringes?
CaHA products usually come in 1.5 ml syringes. For skin quality and tightening on the face the product is usually diluted (for example 1:1); thin-skinned areas such as the neck use higher dilution. A typical facial plan is 1–2 syringes over 1–2 sessions.
What determines the amount?
- How much volume has been lost and where
- Skin thickness and degree of laxity
- Age and factors affecting collagen response (smoking, rapid weight loss)
- Previous fillers or procedures
Does more product mean a better result?
No. With marked excess skin, more product can make the face look heavy and unnatural. In that case surgery or other methods such as endolaser are discussed.
Frequently asked questions
Is one session enough?
Usually not with PLLA; collagen develops gradually, so several sessions are planned.
How long does it last?
With PLLA the effect can last up to about 2 years; it varies between individuals.
Is it the same as hyaluronic acid filler?
No. Hyaluronic acid adds volume immediately; PLLA and CaHA aim for a collagen response.
