Does lemon juice lighten pigmentation caused by acne?

1)acne scar with crater, firstly, need to assess if the skin has healed well before a gentle subcision of the the crater scar. This is followed by a resurfacing, best by a fractional resurfacing laser. Otherwise a spot chemical peel will do well too. often multiple sessions will be needed for both laser and chemical peels. 2)pigmentation it can be many types of pigmentation, from freckles to Post-inflammatory pigmentation(PIH) to moles. pigment laser work well for freckles, but there is down time for 3-5days. PIH can be treated with nonablative laser and creams.

Acne scars and uneven skin texture can be improved using Mosaic or Fraxel whereas pigmentation is best treated using either Q-switched ND:Yag lasers or the newer Picosecond lasers. Mosaic vs Fraxel: Similarities Both lasers use fractional technology. The laser beams create heated columns of “thermal damage” throughout the treated tissue. This results in alteration of the collagen structure in the skin’s deeper layers which creates conditions that are ideal for collagen regeneration and increased elasticity. This results in shallower scars.
