Subcision followed by dermal fillers are good for certain, but not all, acne scars and can give rise to long-term improvement due to de-tethering or freeing the skin from the underlying scar tissue caused by acne.
Other common treatments which give long-term results include resurfacing lasers like Fraxel or fractional CO2 lasers. With repeated treatment, these lasers work well for most acne scars. These lasers replace skin affected by irregular acne scars with flatter, smoother skin. They also stimulate collagen production, causing contraction of the acne scars, making them less obvious. I prefer to use Fraxel as it has minimal downtime.
Recently, PicoSure, a US FDA-approved laser, has been shown to be effective in treating acne scars with even less downtime and discomfort. The laser uses photomechanical disruption rather than heat to comfortably improve scars through LIBO or laser induced optical breakdown. Studies have shown resulting new collagen and elastin production without the side effects and downtime of fractional and ablative lasers.
You may want to discuss this with your doctor before deciding. Cheers!
