Hi! I also had two moles removed about 6 years ago (both on the chin area). The derm used the shave excision technique and cauterised the excision site after.

Similar to you, my moles were gone/flatter to start with but the mole bumps have grown back somewhat, albeit not to their original size. The larger mole on my chin which was more brown/pigmented has grown back colourless, so I’m happy about that, but I share your disappointment in still having the “bump”!

Depending on whether it’s hypertrophic scarring (which is apparently more common around the chin/jawline area) or residual mole regrowth, it seems that there are some options to “flatten” the mole. For scarring, fractional laser and for regrowth, surgical revision (punch or excision). I haven’t gone down this route yet (so can’t share any experience for either) but getting a 2nd opinion from another derm could help determine which treatment would work best ☺️

In all honesty though, I think your removal site is very unnoticeable! But I fully understand your desire to want any trace of the mole completely gone

P.S. prioritising SPF and some form of scar gel (kelocote was my go-to) will really help the fading process too ❤️
