This friend, see for yourself whether there are dermatoglyphics on the left red seal. If there are dermatoglyphics, you can rest assured that it will gradually restore the original skin color. It's only a matter of time. In the meantime, pay attention to protection, don't be exposed to the sun, and use some neutral skin care products.

If there is no dermatoglyphics running through, as long as there is no lump, treatment is generally not needed. The color of this scar will be slightly whiter than the surrounding skin in the future. If there is a bulge that obviously affects the appearance, you can go to the hospital for surgery to remove the scar, and you don't have to go to a beauty salon. Dealing with this small scar, the hospital's technology is not worse than theirs.

It usually takes six months to a year for skin color to return to normal. Sometimes longer, rarely more than two years. Except, of course, large scars. The skin care counter in the store has scar removal products, which may reduce the contrast of skin color. Just try it. Personal opinion, for reference only.
