Is Hyperpigmentation After Vi Peel Permanent?

Vipeel chemical peels can cause post treatment redness, itching,
dryness, and ironically, hyperpigmentation. Early post-peel care is
vital. I would use a curated combination of Covalent peels, fractional
laser, and topical creams to treat the skin after a Vipeel. Start with
Elevase to help with dryness of the skin. Melarase creams are ideal to
combat pigmentation.

Skin should be prepped prior to peels. There are several important reasons for this. One, it helps take off the stratum cornium (the dead skin layer) and allows the peel to penetrate deeper. Second, it reduces the hyperactive pigment cells that can cause post inflammatory hyperpigmentation ( dark spots). Third, it helps  to see how compliant the patient will be with their skin care, in the critical  and vulnerable post peel period.

I like to use a product with Retin A, hydroquinone, Kojic acid, hydrocortisone, Vitamin E and C, for a minimum of six to eight weeks, and even longer in darker skin types, before peeling my patients.

People with darker skin, or genetic background of darker skin, even if they are light skinned, have a greater risk of post inflammatory hyperpigmentation. Prep well before your peel. If you develop  post inflammatory hyperpigmentation, have your doctor start you on a lightening program. See them frequently. Be patient as it  may take a while to improve.

Hi there-
Though this is not a common occurrance with the vi peel, there is always a risk of pigmentation changes after any chemical peel.
Typically this reaction is not permanent and can be resolved. It sounds as though you are experiencing Post Inflammatory Hyperpigmentation. This can be due to inadvertant sun exposure that caused the activation of the pigment cells during the healing process after the peel.
If the skin has not returned to its normal shade after the peeling process is completed, I would recommend seeing the person that performed the Vi Peel and they should be able to prescribe a bleaching cream that you can apply that will lighten the skin.
