Yes. However, acne scars are not a single type of scar, so repeating one device or one method uniformly across the whole face has its limits.
On a single face, lesions at different stages often coexist: active inflammatory acne, early lesions progressing towards scarring, and older scars whose shape is already fixed. Established scars also differ in depth, shape, margins, the degree of tethering to underlying tissue, location and the thickness of surrounding skin. Rather than treating every lesion identically under the single diagnosis of 'acne scarring', we therefore begin by analysing and classifying each scar.
If inflammation is ongoing, the acne itself must be stabilised first, or controlled alongside scar treatment, so that new scars do not form. For established scars, different methods, depths and energies — subcision, fractional laser, microneedling RF and others — are selected or combined according to shape, depth and tethering.
There is one important principle in scar treatment: its essence is not injuring the skin, but reconstructing abnormally tethered scar tissue to the extent required and inducing more normal collagen to form in its place. Neither 'how strongly it was treated' nor 'how quickly it healed' matters on its own; sufficient and accurate therapeutic injury must be created where needed, and that site must then be able to recover as healthy tissue. Conversely, repeating aggressive treatment without regard to the skin's regenerative capacity or current state can lead to a cycle of injury, incomplete recovery and further injury, leaving persistent redness and irritation and a weakened skin barrier. Adequate recovery between sessions and aftercare are therefore part of scar treatment.
Enlarged pores likewise do not all arise from the same cause. Pores with heavy sebum production, pores whose surrounding tissue has been damaged by repeated inflammation, and pores that appear wider through ageing and loss of elasticity each call for a different priority. Rather than repeatedly applying strong energy to the pores, we distinguish the cause, control sebum and inflammation, and induce dermal collagen remodelling where required.
Returning an established scar completely to original skin is not realistic. But by intervening from the stage at which scars form, classifying each existing scar accurately and combining the necessary tissue reconstruction and regeneration, the depth and margins of scars and the overall texture of the skin can be improved progressively.
