Cellulite and Stretch Mark Treatment in Singapore

Cellulite treatment in Singapore matched to the cause of dimpling

Cellulite is the dimpling produced when fibrous bands (septae) tether the skin to deeper tissue while fat pushes up between them, over a dermis that has thinned and lost collagen support. It is not a fat problem alone, so weight loss and creams do not remove it.¹ The Skin Longevity Clinic treats cellulite on the thighs and buttocks by matching each treatment to its cause. Poly-L-lactic acid (PLLA) and poly-D,L-lactic acid (PDLLA) collagen biostimulators and extracellular matrix (ECM) skin boosters thicken the dermis, Bellasonic LDM ultrasound improves skin texture, subcision releases the fibrous bands behind deep dimples, fractional laser improves surface texture, and radiofrequency tightens lax skin. Severity also guides the choice. For moderate cellulite, current evidence favours energy-based devices, among which radiofrequency shows the strongest results. Severe cellulite is best treated with subcision and injectables, whereas mild cellulite is managed first with lifestyle measures such as exercise.¹

A 2025 systematic review of 24 randomised trials (2,084 patients) found the most promising results for shockwave therapy, radiofrequency and injectable treatments.¹²

Cellulite treatments compared

PLLA collagen biostimulator for cellulite

PLLA is injected across the dimpled area as a dilute suspension. Its microparticles trigger a controlled tissue response in which fibroblasts lay down new collagen around them as the particles are slowly absorbed over several months, thickening the dermis so dimples become shallower and the skin looks smoother. In a randomised, double-blinded split-body trial, 20 women with mild to moderate cellulite and skin laxity received three PLLA sessions four weeks apart on one side and water injections on the other. The treated buttocks showed shallower depressions and less laxity, and the treated thighs fewer and shallower depressions, over 11 months of follow-up.² A 2025 international consensus supports PLLA for body skin quality, laxity and cellulite, typically as two to three sessions four to six weeks apart, although the evidence base is still largely observational.³ A 2026 study treated grade 2–4 cellulite on the back of the thighs with one to three sessions four to six weeks apart. At month 9, 28 of 29 patients (97%) were rated improved, improvement held at 93% or more through month 12, and no treatment-related adverse events were reported.¹³ Further detail is on the clinic’s PLLA collagen biostimulator page and in the collagen biostimulator treatments guide.

PDLLA collagen biostimulator for cellulite

Poly-D,L-lactic acid (PDLLA) is a collagen biostimulator related to PLLA, with a different particle structure, and it is reconstituted and injected in a similar way.¹⁴ There are no published trials of PDLLA for cellulite. It is used for the same purpose as PLLA: to thicken and firm the skin over the dimples. It suits mild to moderate cellulite where thin, crepey skin is part of the problem. Read more on the clinic’s PDLLA collagen biostimulator page.

ECM skin boosters for cellulite and skin quality

ECM skin boosters are made from human acellular dermal matrix, which is donor dermis with the cells removed, and are injected into the dermis to restore the matrix itself rather than add a single ingredient. In a randomised, double-blinded split-face trial in 20 adults, the matrix booster improved skin density, elasticity, wrinkle depth and hydration more than hyaluronic acid over 20 weeks.⁵ No trial has yet tested it on cellulite or stretch marks, so its use on the body is extrapolated from this facial evidence to the thin, crepey skin over cellulite and to mature stretch marks. At the clinic, ECM boosters are used alone for mild dimpling with poor skin quality, or with PLLA where laxity is also present. The ECM skin boosters page and the skin boosters in Singapore comparison describe the product in detail.

Bellasonic LDM for cellulite

Bellasonic uses LDM (local dynamic micro-massage), a multi-frequency ultrasound technology. In a 2024 case series, 20 women with cellulite had triple-frequency LDM as the only treatment. The average cellulite severity score fell from 2.22 to 1.18 by the last session and to 0.84 at follow-up, about one grade of improvement, with 8.95/10 satisfaction and no side effects.¹⁵ The study was small, had no control group, and one author works for the device manufacturer. LDM is non-invasive and needs no downtime, so it pairs well with injectable collagen biostimulators. Read more on the clinic’s Bellasonic LDM page.

Combination treatments for deeper cellulite

When dimples are deep or the skin is loose, the first-line treatments above are combined with subcision, fractional laser or radiofrequency.

Subcision for cellulite dimples

Deep, well-defined dimples are caused by fibrous septae pulling the skin down, and subcision releases them. Under local anaesthetic, a fine needle or cannula is passed beneath the dimple to cut the bands, and the skin lifts as the released space fills with new connective tissue.¹ Bruising lasts one to two weeks. Subcision is often combined with PLLA in the same session. In a series of 24 women with cellulite and skin laxity of the buttocks and thighs, the combination most often earned a “great improvement” rating from an expert panel, and no nodules formed.⁴ The same release technique is used for rolling acne scars (see subcision for acne scars).

Fractional laser for cellulite skin texture and stretch marks

Fractional laser creates microscopic columns of heat injury separated by untouched skin, and the columns heal with new collagen. The result is smoother surface texture, less crepiness, and narrower, softer stretch marks.⁸ On cellulite, fractional laser treats the skin surface rather than the dimples, so it is used alongside subcision or PLLA and not alone.¹ A course runs to three to five sessions four to six weeks apart, and redness and fine grazing settle within three to five days. In darker skin, energy and density are kept low to limit post-inflammatory darkening.

Radiofrequency for cellulite with skin laxity

Where cellulite comes with loose skin, radiofrequency is added to heat the dermis, which contracts existing collagen and stimulates new collagen to tighten the skin. RF microneedling is used for skin texture, and XERF body treatment for the thighs, abdomen and arms. In a prospective multicentre trial of a subcutaneous microneedle radiofrequency device in 50 people with moderate to severe (grade II to III) thigh cellulite, a single treatment improved dimple number or severity in 93 per cent at six months.⁶ Radiofrequency microneedling remodels collagen gradually, with improvement continuing for at least six months, and is safe in darker skin types.⁷

Stretch mark treatment in Singapore

Stretch marks (striae) are tears in the dermis caused by rapid stretching during pregnancy, growth spurts or weight change. They are red or purple when new (striae rubra) and white and depressed when mature (striae alba). A systematic review of 151 studies found that collagen-stimulating treatments improve the width, depth and texture of stretch marks, but complete clearance was rare with any method.⁸ In a meta-analysis, microneedling-based treatment performed as well as laser with less post-inflammatory darkening, an advantage in Asian skin.⁹ The plan at the clinic depends on the stage of the marks.

• New red stretch marks are treated with an ECM skin booster to support dermal repair while the marks are still active.
• Mature white stretch marks are treated with PLLA injected along the marks to thicken the thinned dermis, with the 1540 nm erbium glass laser (Secret DUO) or RF microneedling for texture.
• Stretch marks with loose skin after weight loss or pregnancy are treated with the same injectables combined with XERF body (see loose skin after weight loss).

Cellulite and stretch mark treatment sessions and results

PLLA is given as two to three sessions four to six weeks apart, with results building over six months and lasting 18 to 24 months.³ PDLLA is planned at consultation on the same schedule principle. ECM boosters are given as one to two sessions and reviewed at three months.⁵ Bellasonic LDM is given as a course of sessions.¹⁵ Collagen biostimulator results build gradually over two to three months as collagen forms. Subcision is usually a single session per area, reviewed at three months. Fractional laser requires three to five sessions, and RF microneedling three sessions four weeks apart. Cellulite is photographed and graded at baseline and at each review, and improvement of about one grade is typical, not complete removal.^1,2

Cellulite treatment risks

Subcision causes bruising for one to two weeks and temporary lumpiness, and rarely over-correction or a collection of blood under the skin (haematoma). Fractional laser causes redness for a few days and can cause post-inflammatory darkening in darker skin if the settings are too high. Injectables cause bruising, swelling and tenderness for about a week. PLLA can also form small nodules if it is placed too superficially or not massaged, so treated areas are massaged for five days after each session.³ PDLLA carries the same risks of bruising, swelling and, uncommonly, nodules. No side effects were reported with Bellasonic LDM in the cellulite study.¹⁵ Radiofrequency causes redness and swelling for a few days, with rare burns or pigment change if settings are incorrect.⁷ None of these treatments is performed during pregnancy or breastfeeding.

What affects cellulite treatment cost in Singapore

The cost of cellulite treatment depends on the area treated, the cellulite grade, the treatments combined (PLLA, PDLLA, ECM boosters, Bellasonic LDM, subcision, fractional laser and radiofrequency), the number of collagen biostimulator vials and the number of sessions.

Cellulite and stretch mark treatment FAQs

Can cellulite be removed completely?

No treatment removes cellulite entirely. Subcision, collagen stimulation and radiofrequency together reduce dimpling and improve skin texture, typically by about one grade.^1,2

Which cellulite treatment is best?

The choice depends on the cause. Subcision treats deep dimples from fibrous bands. PLLA has randomised trial evidence for cellulite of the buttocks and thighs² and a 2026 posterior-thigh study,¹³ and PDLLA works on the same collagen-stimulating principle. ECM boosters are chosen when thin, crepey skin is the main problem, and Bellasonic LDM suits mild to moderate cellulite. Most plans combine two treatments.

Do stretch marks go away with treatment?

Mature stretch marks fade and narrow with collagen-stimulating treatment but rarely disappear, and new red marks respond best.^8,9

How many sessions are needed for cellulite?

A typical plan is two to three PLLA sessions or one to two ECM sessions, with radiofrequency added if laxity is present. Results are judged at six months.³

Does losing weight fix cellulite?

Weight loss reduces fat volume but does not release the fibrous bands or reverse the dermal thinning that cause dimpling, and it can make skin laxity more visible.¹

Does Bellasonic work for cellulite?

In a 2024 study of 20 women, a course of LDM ultrasound improved cellulite by about one grade, with no side effects.¹⁵ It works best on mild to moderate cellulite and is often combined with a collagen biostimulator.

PDLLA or PLLA for cellulite: which is better?

PLLA has the cellulite trial data, including a randomised trial and a 2026 thigh study.^2,13 PDLLA works on the same principle but has not been tested for cellulite. The choice depends on skin thickness, the area and how many sessions suit you.

Is there a permanent treatment for cellulite?

No treatment removes cellulite permanently, because the fat lobules and septa that cause it remain. Collagen biostimulator results lasted to 12 months in the 2026 study,¹³ and maintenance sessions keep the skin firmer.
