PLLA, in no hurry

Poly-L-lactic acid isn’t a filler in the way people mean the word. A hyaluronic gel works by occupying space: it goes in, it takes up volume, the shape changes while you’re still in the chair. PLLA works by conversation. It’s a fine polymer, suspended in liquid and placed in the deeper planes, where it does nothing except prompt your own tissue to rebuild — gradually laying down fresh collagen and matrix over the months that follow.

The fullness you leave with is water

This is the part worth hearing twice. Whatever plumpness you see in the mirror on the way out is mostly the carrier fluid and a little swelling, and it drains away within days. People who don’t know this panic in the first week, certain it has failed. It hasn’t. The real change arrives quietly, weeks to months later, and it usually takes a short series of sessions spaced a few weeks apart before the whole picture is there.

It doesn’t fill your face. It asks your face to rebuild itself.

That slowness is exactly why it looks the way it does. Because nothing is added all at once, there’s no day when friends notice a change; there’s a month when they think you look well. For diffuse loss — a face that has thinned generally rather than fallen in one spot — it’s one of the few things that can answer honestly. When it works, the effect tends to hold for a year or two: a range, not a promise, and the evidence behind those numbers is thinner than the marketing suggests.

Who it suits — and who shouldn’t have it

PLLA suits someone with generalised volume loss and softening tissue quality, who wants gradual change and can be patient. It’s a poor choice for a small, precise correction, for anyone who needs to look different by Thursday, and for lips — classic PLLA has no business in a lip. Active infection or inflammation at the site means we wait. Pregnancy, breastfeeding, a history of keloid, connective-tissue or inflammatory disease each need an individual conversation rather than a rule.

The honest caveat

Two things separate it from hyaluronic acid, and both cut the same way. First, there is no antidote: a hyaluronic filler can be dissolved with an enzyme in an afternoon if you dislike it; PLLA cannot. Second, its signature problem is a small lump that can appear under the skin months later — uncommon, made less likely by careful depth, even placement and diligent aftercare, but never reducible to zero. Anyone quoting you a precise percentage is quoting marketing, not evidence.

Which makes PLLA a decision rather than a purchase. It rewards the patient and punishes the impatient; it depends far more on the hand and the plan than on the vial; and it doesn’t come back if the plan was wrong. That’s why the consultation matters more here than almost anywhere else — and why, more often than with anything else we offer, the honest answer is sometimes that this simply isn’t your treatment.

Frequently asked questions

When will I see the result of PLLA?

Not on the day — the fullness you leave with is carrier fluid and settles within days. The real change builds over weeks to months as your own collagen forms, usually across a short series of sessions.

How long does PLLA last?

For many people the effect holds around one to two years, but that is a range rather than a promise: it depends on the product, the amount, the area and your own tissue.

Can PLLA be reversed if I don’t like it?

No — unlike hyaluronic-acid filler, there is no enzyme that dissolves it quickly. That is exactly why patient selection and a careful plan matter more here than almost anywhere else.

Where can I have PLLA in Karaj?

PLLA is performed by Dr. Mostafa Havasi at the Azimieh clinic in Karaj (with a second clinic in Tehran, Chitgar); a private, no-obligation consultation decides whether it suits you at all.
