Ageing is not only about lines — it is about the quiet loss of the collagen that holds your face up.

Sculptra for collagen loss and volume is a poly-L-lactic acid (PLLA) injectable that gradually restores facial volume by stimulating your own collagen, rather than filling a line instantly — giving a subtle, natural rebuild over several months.

Why we lose collagen and volume

The ageing timeline

Collagen makes up a large share of the skin’s structure, and production declines steadily from our mid-twenties. The result is flatter cheeks, hollow temples and softening contours.

Why volume loss ages the face

As deep support fades, the overlying skin has less to rest on, so folds deepen and the face can look tired — even when the skin surface is well cared for.

How Sculptra restores collagen and volume

The active ingredient

Sculptra is made of poly-L-lactic acid, described by the Cleveland Clinic as a collagen stimulator that absorbs into the body and encourages cells to produce more collagen.

The gradual rebuild

A published review describes how PLLA promotes collagen through fibroblast activity and thickens the dermis, so volume returns progressively rather than all at once.

Which areas Sculptra treats

Sculptra is well suited to broad, gradual volume restoration:

• Cheeks and mid-face flattening
• Temples and the area beside the eyes
• Nasolabial folds and marionette lines
• Jawline and pre-jowl softening
• Overall skin quality and firmness

Where it is not first choice

For precise lip shaping or the tear trough, HA dermal fillers are usually preferred because they add controlled, immediate volume.

Sculptra compared with other options

Ranges are typical and individual results vary. See our Ellanse vs Sculptra comparison.

What results look like and how long they last

The timeline

Most people see gradual improvement over about six weeks to a few months as collagen builds, with the fuller effect after a completed series.

Longevity

Sculptra results can last up to around two years in many people, after which a maintenance session helps sustain the effect. Longevity varies with age, skin and lifestyle.

Preparing for and recovering from Sculptra

Simple steps support a smooth treatment and the best collagen response:

1. Have a consultation with Dr. Narathai to map areas and confirm suitability.
2. Avoid alcohol and blood-thinning supplements for 24–48 hours before, where appropriate.
3. Arrive with clean, make-up-free skin.
4. After treatment, follow the 5-5-5 massage guidance your clinician provides (massage the area 5 minutes, 5 times a day, for 5 days).
5. Avoid saunas, intense sun and heavy exercise for the first day or two.
6. Return for your next session on schedule to complete the plan.

Safety and choosing the right clinic

An experienced injector

Because PLLA is not dissolvable, even placement and correct reconstitution matter. Choose a licensed medical clinic with doctors experienced in biostimulators.

Genuine Sculptra

LIV Clinic uses genuine, medical-grade product and follows an open-box approach, and we caution against unverified or non-medical injectables.

Sculptra in Koh Samui

On Koh Samui and Koh Phangan, Sculptra appeals to people who want a longer-term investment in skin structure rather than a quick fix. Many start a plan on the island and continue maintenance over the year. Cost is usually quoted per vial and depends on how many vials your face needs, confirmed at consultation. Explore our collagen-stimulation treatments or book a consultation.
