Can I use brightening products on a healing insect bite or picked spot?

Care for the wound first and avoid picking. Do not apply exfoliating products to an open area. Once the skin is fully closed and comfortable, you can reassess discoloration without treating an active wound as a pigment problem.

Heal the skin before treating the mark

After it has healed, sun protection can help limit discoloration; there is no single day when every brightening product automatically becomes suitable.
