Aww sis, nakakaintindi ko, visible talaga ang dark marks especially kapag maputi ang skin! Kasi naman ang rashes, pag nag-heal sige na ng post-inflammatory hyperpigmentation, na mahirap mawala agad. Sunscreen talaga ang biggest help (SPF 50+, lagi) para hindi lumala pa ang pangitim habang nag-heal, at moisturizer na gentle like lotion o cream para hindi ulit mag-irritate ang leeg mo, try mo Mama's Choice Face Moisturiser, safe sya even sa sensitive areas and really calming. But honestly, kung nag-worsen pa or hindi umalis within weeks, best to check with derma para alam mo kung may need ng treatment like tretinoin o vitamin C serum para talaga mabilis unwrap yung dark marks, totally worth it!
