I have brown skin, with hyperpigmentation on my neck caused by a cut I sustained years ago. I've since had an IPL, CO2 Laser, Chemical Peel, and steroid injections, and now my scar is extremely smooth, but dark brown in color! I tried an at-home TCA peel, which made my skin peel, get dark, and lighten up a shade! Should I keep doing the peels, opt for another laser treatment, or stick to bleaching creams?
Should I Stick with At-home Peels for Hyperpigmentation?

TCA useful for hyperpigmentation
TCA ise a useful peel for irregularites of the skin such as hyperpigmentation and dark patches. Further, TCA is a chemical peeling agent that smooths fine lines and removes some skin imperfections such as brown spots and sun damage. TCA may be combined with another peeling agent known as Jessner's solution. This allows a more uniform and thorough result. TCA is generally conisdered a"medium depth" peel and thus you should expect more than you would acheive with a glycolic peel, but less than with laser skin resurfacing. Healing time is usually 3-5 days.
Reducing Hyperpigmentation Associated With a Scar: Scar Reduction
Scars that are hyperpigmented have usually undergone a melanin stimulatory phase of wound healing that is exacerbated by inflammation.
In these cases, the first course of treatment should always be topical creams. If this does not completely improve the pigmentation, a chemical peel is warranted.
A series of light TCA peels should help
As long as the peels are not too aggressive, the skin should continue to lighten with additional TCA peels. Aside from the at-home peels, topical tretinoin cream (Retin-A) can help as well.
