What can I do to get rid of two childhood scars? (Photos)

After three months a scar is considered mature and, unfortunately, even with the best of treatments or combinations of treatments available today, the best improvement in appearance that can be realistically obtained ranges between a 60-80 percent overall improvement in appearance.
At least from the photos, the scars appear indented. So, I would subcision to elevate and smooth them as much as possible. Following this, I would consider the use of manual, mechanical Microneedling (no need for the added expense or risks of RF microneedling) accompanied by the topical application of Rx pigment enhancing agents, such as tyrosine and latanoprost, in order to blend the scars better in both color and texture with the surrounding normal skin.
You would be wise to consult with an experienced, board certified cosmetic dermatologist scar treatment specialist and best of luck.

Thank you for sharing your concerns and history. Scars that have been present since childhood are usually more resistant to treatment because the skin has had many years to remodel and mature. That being said, there are still approaches that can help soften their appearance and improve skin texture, even if complete removal is not possible.

Since you’ve already tried several resurfacing methods such as microneedling, laser, retinol, and peels, the next steps often involve combining treatments or trying more targeted procedures. Options can include:
Fractional or ablative lasers (such as CO₂ or erbium) which can sometimes provide deeper resurfacing than non-ablative lasers.

Surgical scar revision for very stubborn or linear scars, this involves carefully excising and re-closing the scar to make it less visible.

Fillers or fat grafting if there’s any indentation, as they can help lift and smooth the area.

Advanced resurfacing techniques like radiofrequency microneedling, which can stimulate deeper collagen remodeling.

While treatments may not erase scars entirely, a combination approach often leads to noticeable improvement in blending them into the surrounding skin.

It’s also worth keeping in mind that sun protection and ongoing topical care (such as retinoids) can support any procedural results and prevent the scars from standing out more with time.
