1. Diagnose the cast
Decide what you are cancelling: blue/purple (vascular congestion, smoker's lip, some ethnic pigmentation), brown (melanin), or grey (old tattoo, mixed). Photograph in neutral light; note where it is worst (border, lower lip, patches).
2. Pick the corrector
Blue/purple → warm orange corrector. Brown → warm peach, lighter value. Grey → warm gold plus a brightener. Correctors are iron-oxide-dominant and deliberately warmer/lighter than the final colour.
3. Base layer, lightly
Apply the corrector as an even pixelated base across the affected zones, not packed. Resist the urge to also apply 'the pretty colour' the same day on badly discoloured lips — you will just bury the grey.
4. Heal and reassess
Wait the full 6–8 weeks. Judge the healed neutralisation. Deep cases need a second (occasionally third) corrector session before the cast is gone.
5. Add colour
Once the base heals even and warm, a normal blush colour goes on in a later session and finally 'takes' true. Set the expectation throughout: the destination is even and healthy, not bright.
