Dermal Filler

Fillers are not a single product but a family of materials that share one idea: placing a soft, biocompatible substance under a depression so the surface sits more level with the skin around it. Hyaluronic acid gels are the most widely used and have their own dedicated entry; this entry focuses on the filling approach itself, especially for rolling or shallow boxcar acne scars and other localized dents, with collagen stimulators such as poly-L-lactic acid or calcium-based materials as the slower-acting branch of the family.

What filling can address is a volume deficit: a soft depression that flattens when the surrounding skin is gently stretched is the classic target. What it cannot do also matters. It does not treat active acne, redness, or pigmentation left behind by breakouts, and it works poorly on narrow, deep ice-pick scars. Scars tethered down by fibrous bands often need a release procedure such as subcision first, or the filler simply sits around a still-anchored pit.
