Is TCA 12-13% Spot Treatment Effective for Hyperpigmented Areas on Face?

I have a few small hyperpigmented areas of melasma on my cheeks & my doctor suggested treating them initially with spot application of TCA 12-13% (applied to the affected areas only) followed by full face 40-50% glycolic acid peel. Is this treatment effective or should I skip the spot treatment & stick with only full face GA peel?

Your doc is correct in doing spot treatments

Spot treatments work good for dark spots and may need a few sessions then later require full face peels to blend everything together. Trust your doc.

Combining glycololic acid peels with low strength TCA peels can be very effective for dark spots.

Combining glycololic acid peels with low strength TCA peels can be very effective for dark spots. I first described this approach in the journal Dermatologic Surgery in 1994. Each person's treatment must be customized by a dermatologist very experienced in chemical peeling or the dark spots can be made worse.
