Chemical Peel to Enhance Absorption of Bleaching Creams?

Multiple light chemical peels work best such as Jessner's solution ($175 per peel) or 10-15% TCA peels ($250 per peel) done every 2 weeks for 3-6 peels. Also, using a bleaching cream which has retin A in it and a cortisone cream as well do really nice. 

Yes, based on a most recent study, monthly superficial chemical peel can help with the efficacy of Triluma cream. The key word here is superficial, especially for dark-skinned people. I think among all the superficial peels, salycylic acid peel is the safest for dark skin types.

Yes - light or superficial chemical peels can not only help with even out skin tone, they can also help improve the penetration of any topical skin care products you are using to correct the skin tone. I agree with the other comments that care must be taken in dark skin not to irritate the skin too much as this can lead to post inflammatory hyperpigmentation or PIH. If you get any irritation or excessive peeling or dryness from a peel - keep area coated with vaseline or a thick moisturizer to help healing.
