When will redness be gone after Vi Peel?

It is not advisable to peel off the skin. You should let it slough off naturally. Peeling off the skin will prolong your healing time and increase redness. The redness should resolve over time. During the peeling process you should apply the post peel protectant as needed. There is a post peel kit that comes with instructions as well. You should consult with the person who performed your peel.

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.

Your skin will most likely take longer to recover because you exposed skin that was not ready to be exposed.  This also puts you at higher risk for hyperpigmentation.  Follow up with your provider and be sure to follow all your discharge instructions. 

Hi there-
Everything you have explained sounds like a normal reaction to the vi peel.
It is very important however that you do not try to pull off the dead skin as this can take healthy tissue with it and leave the new skin very red and inflamed.
The redness will heal but may take a few days to subside after you have finished peeling. Typically the peeling process is complete by the end of day 5 and then the skin remains pink and somewhat sensitive for another 2-3 days after that.
By day 10, most patients are very pleased with how their skin looks and feels and do not have any remaining redness or irritation.

Thank you for your message! It is difficult to fully assess your concerns without pictures. We advise that you do not peel the skin off yourself, but rather let it come off as you wash your face or apply moisture to the skin. Peeling the skin off yourself increases the risk of scarring or inflammatory issues. Any redness is normal after chemical peels, but you may have prolonged the healing process as bit. I would follow up with your provider for further information or assistance!
