Profhilo vs Fillers — The Key Differences and When to Use Each

Profhilo and dermal fillers are both injected into the skin — but they do fundamentally different things, produce different outcomes, and suit different clinical goals. The confusion between them leads to patients receiving inappropriate treatments. Dr. Sin Yong's clear clinical explanation of the distinction and how he decides which to use.

What Profhilo Is — and Is Not

Profhilo is an injectable containing ultra-pure, high-concentration hyaluronic acid. It is not a filler. It does not add volume, create projection, or lift tissue. Profhilo disperses through the skin tissue rather than remaining in a bolus, stimulating collagen and elastin production in the dermis. The result is improved skin quality from within — greater elasticity, improved hydration, increased firmness and luminosity. Skin that has had Profhilo looks and feels healthier — not fuller or more projected.

What Dermal Fillers Do

Dermal fillers add volume and structural support to specific anatomical zones — correcting hollowness (tear troughs, temples, cheeks), creating projection (chin, nose, lips) and lifting descended tissue by volumising deep fat compartments. Fillers produce an immediate, visible result. Used incorrectly — with excessive volume or in the wrong plane — they produce the characteristic overfilled, pillowed appearance.

Dr. Sin Yong's Conservative Philosophy

Dr. Sin Yong is cautious about fillers. He has observed that many patients seeking his help are carrying excessive prior filler volume — sometimes from multiple clinics over years — that contributes to, rather than corrects, an aged appearance. His approach to fillers is conservative: the minimum effective amount, placed precisely, to achieve a natural result. He frequently recommends Profhilo as a better first-line injectable for patients seeking overall facial improvement.
