HArmonyCa กับ Profhilo ต่างกันอย่างไร?

The table below compares HArmonyCa, Profhilo and Sculptra on what first-timers usually ask: which concern each suits, how it is injected, what the evidence says and what to watch for. Data come from the clinic's service pages and the studies that could be checked. The figures come from studies designed differently, so they cannot be compared directly across columns, and the table is not a ranking.

Thai registration status of all three products was not checked in this article. Ask to see the box, label and Thai FDA registration number of the product actually used before every injection. Service details: HArmonyCa, Profhilo and Sculptra

HArmonyCa vs Profhilo: the short answer for first-timers

In the simplest terms, HArmonyCa works in the deeper layer to support tissue and add some volume, while Profhilo works in the skin layer to improve skin quality; it is like reinforcing the frame underneath versus conditioning the surface above. This is an analogy to help picture it, not a detailed medical explanation. Per the clinic's service pages, HArmonyCa is a hybrid filler and not a lifting device^[2] , and Profhilo is not injected to add volume.^[3]

The clinic's earlier article compared the two along the same lines^[1] . Checking against the research, no study compares the two directly, so every figure here comes from studies of each product separately. If you are not yet sure what a biostimulator is or how it differs from a filler, start with How do biostimulators differ from fillers

Why "which is better" is the wrong question

Because the two answer different problems. Someone whose cheeks are flattening and jawline is blurring has a volume and structure problem; someone with dry, mildly slack skin has a skin-quality problem. The choice should start from your goal and facial anatomy, not from a product name.^[2][3]

Ingredients, injection layer, and what is Profhilo Structura

HArmonyCa: HA plus CaHA

HArmonyCa is made by Allergan Aesthetics and contains cross-linked HA 20 mg/mL plus CaHA particles at 55.7% w/w, injected in the deep dermis and subdermal layers according to the studies and the product information the clinic cites^[2][5] . The idea is that HA gives volume and support early, while CaHA is the component thought to stimulate collagen. In a 15-person study using ultrasound and elastography, collagen fibers increased from day 60, were confirmed at day 90 and peaked between days 90 and 180; another 15-person study found dermal thickness increased at 90 and 120 days. Both were small studies.^[6][7]

Profhilo: high- and low-molecular-weight HA combined

Profhilo, from IBSA, combines high- and low-molecular-weight HA as complexes, injected as small points in the dermis. A review of postmarketing data describes it as made by a heat process without chemical cross-linkers and with low viscosity^[11] . The clinic's service page says the collagen claim comes from cell experiments and has not been shown directly in human skin^[3] . As for regulatory status, per a company press release from July 2026 the product still needs U.S. approval before sale there, and its Thai status was not checked.^[18]

HArmonyCa vs Profhilo Structura: how do they differ?

Profhilo Structura is another IBSA version. In the sources checked, the only information found is trial registration NCT06719154, sponsored by IBSA. Its title says it evaluates the safety and efficacy of Structura for face adipose tissue restoration, its status is recruiting, estimated enrollment is 164, and it describes a product with high- and low-molecular-weight HA that has not been chemically modified^[14] . No published results were found, so Structura cannot be compared with HArmonyCa using numbers.

What can be said carefully is that the study title suggests Structura is being developed for facial volume goals, unlike the original Profhilo, which the clinic's page describes as aimed at skin quality^[3][14] . The clinic's Profhilo page does not mention Structura, so anyone interested should ask whether it is offered and request the product registration details before deciding.

Does one work faster or last longer? What the evidence shows

HArmonyCa: peak around months 3-6, then a decline

In the 140-person open-label post-marketing study without a control group, the share rated improved by at least one grade was 82.8% at month 1, 84.8% at month 3, 82.7% at month 6, 74.8% at month 9 and 65.9% at month 12. The authors concluded results last about a year, but the figures were not constant and most participants had lighter skin^[5] . The study was manufacturer-funded.^[2]

Profhilo: mild to moderate skin-quality change, results vary by study

The 64-person study was a single-site open-label study with 2 sessions 4 weeks apart; improvements were significant from week 4 or 8 and still significant at week 16^[10] . The neck study of 25 people found laxity improved 15% at 1 month and 21% at 4 months, with no control group and IBSA as funder^[9] . In contrast, a randomized split-face trial of 12 people around the mouth, against saline, found 3D images showed improved wrinkles and pores, but skin thickness was no greater than the saline side, and some respondents were dissatisfied^[12] . A systematic review of 9 studies and 278 people, mostly by authors linked to the manufacturer, concluded several measures improved or tended to improve.^[13]

Common claims versus the evidence

• HArmonyCa lasts longer than Profhilo: no direct comparison was found. The HArmonyCa study followed people for 12 months, while the Profhilo studies checked followed people for less time (4 months in the neck study and 16 weeks in the face study). A shorter follow-up does not mean results fade sooner.^[5][9][10]
• Profhilo works faster than HArmonyCa: the 64-person study found significant differences from week 4-8, and HArmonyCa had 82.8% responders at month 1, but the measures and raters differ, so they cannot be compared directly.^[5][10]
• Profhilo vs Sculptra: Sculptra is PLLA injected under the skin in several sessions and belongs to the biostimulator group, while Profhilo is HA injected in the skin layer. Sculptra's 149-person cheek trial against no treatment showed results at month 12, but some authors were affiliated with the manufacturer.^[4][15][16]

Risks, side effects and cautions for HArmonyCa and Profhilo

HArmonyCa: the 2025 open-label study found injection-site reactions in 95.7%, mostly mild to moderate. The most common treatment-related effects were injection-site pain 11.4%, lumps 10.7% and headache 7.1%. No serious treatment-related adverse events were found, but 8 mild events (mostly lumps) were still present in 6 participants at the end of the study^[5] . An advisory-board meeting of 13 European physicians concluded that managing complications of HA-CaHA is similar to managing those of single-agent fillers, and stressed knowledge of anatomy, aseptic technique and correct injection technique.^[8]

Profhilo: the 64-person study reported minor, temporary local reactions in 23%^[10] . Postmarketing data covering more than 40,000 patients over 3 years logged 12 adverse-event reports, none classed as serious, but these are reports sent to IBSA's safety database, and the authors say they cannot rule out under-reporting of minor events.^[11]

A risk common to all injectables is vascular occlusion, which a review of filler complications describes as a serious condition that must be recognized and managed promptly^[17] . If you have unusually severe pain, rapidly pale or discolored skin, abnormal mottling, or any change in vision after injection, contact a doctor immediately. People who are pregnant, breastfeeding, on anticoagulants or prone to raised scars should tell the doctor before every treatment.^[3][4]

Choosing the one that matches your goal

• Flattening cheeks, blurred jawline, loss of mid-face volume: HArmonyCa is the option studied in this group, but accept the limits of manufacturer-funded evidence, and it is not suited to the eye area or lips.^[2][5]
• Dry, mildly to moderately slack skin, wanting better skin quality without changing face shape: Profhilo matches the goal per its service page, but expect modest results that vary between people.^[3][12]
• Wanting gradual results and accepting that correction is harder than with HA filler: Sculptra is another option in the biostimulator group, with randomized trials of low overall quality.^[15][16]
• Deep folds or spot-specific reshaping: another HA filler may fit better; see. Fresh Code Clinic fillers
• Wanting to combine the two: no study of HArmonyCa together with Profhilo was found in the sources checked, so the doctor should assess individually and set the sequence and interval.

Before deciding, ask to see the box and label of the actual product, ask how many sessions and how much product the doctor plans, and ask what the plan is if a lump forms or you are unhappy. More on collagen-stimulating options is in How do biostimulators differ from fillers

FAQ (Frequently Asked Questions)

Conclusion

HArmonyCa and Profhilo differ in goal and injection layer. HArmonyCa is a hybrid HA-plus-CaHA filler injected deeply for volume and tissue support, while Profhilo is HA injected in the skin layer to improve skin quality. No study compares them directly. HArmonyCa's rated improvement fell from 82.8% to 65.9% over 12 months in a study without a control group, Profhilo has a small split-face trial where skin thickness was no better than saline, and the Structura version is still under study.^[5][12][14]

Anyone looking for a Profhilo or HArmonyCa clinic that feels private and hassle-free should ask about the consultation room, advance booking and who will inject before booking, and verify the doctor's license with the Medical Council of Thailand.
